The objective of this study is to present a surgical approach to reactive lesions for rehabilitation purposes in an elderly patient. A 63-year-old male patient presented to the dental clinic of a higher education institution reporting swelling in the inner/upper part of his mouth, as well as aesthetic dissatisfaction when smiling. During the medical history, he reported that he had used the prosthesis for approximately 5 months but stopped using it continuously due to severe pain in the areas corresponding to the "edges" of the prosthesis, but he did use it while chewing. On intraoral examination, lesions with a hyperplastic appearance could be highlighted in the fundus of the vestibule of the upper arch bilaterally. Based on the clinical characteristics presented, it was decided with the patient to remove the lesions surgically, followed by referral for prosthetic rehabilitation. The fragments were removed and sent for confirmation of the condition, confirming the hypothesis of reactive fibroepithelial hyperplasia. The patient was then referred for prosthetic rehabilitation. Surgical approach for conditioning of gingival tissue prior to rehabilitation treatment is, therefore, a viable option with a good prognosis when it comes to a reactive lesion, making the environment suitable for the installation of removable prostheses.

RESUMO Objetivou-se descrever a condição de saúde bucal de idosos institucionalizados, com enfoque no edentulismo, na necessidade de prótese e na Autopercepção de Saúde Bucal (ASB), e explorar a associação com fatores individuais. Um estudo transversal foi realizado em Ponta Grossa, município do Sul do Brasil, com amostra de conveniência de idosos residentes em três Instituições de Longa Permanência para Idosos. Por meio de questionário estruturado, foram coletados dados sobre características demográficas, de saúde geral e bucal e acesso a serviços de saúde. No exame bucal, avaliou-se o Índice de dentes permanentes Cariados, Perdidos e Obturados (CPO-D), número de dentes presentes, uso e necessidade de prótese dentária e presença de lesões bucais. Foram avaliados 130 idosos, a maioria com mais de 80 anos (62,20%). O CPO-D médio foi de 30,62 (desvio-padrão 2,85), 62,31% dos idosos eram edêntulos, 41,54% usavam e 79,23% necessitavam de prótese dentária. As lesões bucais foram identificadas em 35,42% dos avaliados, e 64,86% dos idosos classificaram a ASB como boa. Conclui-se que a saúde bucal dos participantes foi considerada ruim, do ponto de vista clínico, levando em consideração a alta prevalência de edentulismo e a necessidade do uso de prótese dentária.

O objetivo do presente estudo foi analisar a expansão da oferta de prótese dentária pelas Equipes de Saúde Bucal (ESBs) conforme as regiões geográficas brasileiras. O estudo de série temporal foi realizado com dados secundários do Módulo II do 1º ciclo (2011-2012), Módulo VI do 2º ciclo (2013- 2014) e Módulo V e VI do 3º ciclo (2015-2018) do instrumento de Avaliação Externa do Programa de Melhoria do Acesso e Qualidade da Atenção Básica (PMAQ-AB). Houve comparação das proporções entre as regiões brasileiras pelo teste Qui-quadrado, e entre os anos pelo teste Q de Cochran, com uso do teste z ajustado pelo método Bonferroni (p0,05). A Prótese Parcial Removível aumentou no Brasil de 2012 (25,7%) para 2014 (30,5%) (p

The search for an aesthetically attractive smile has been a striking feature in contemporary society, driving modern Dentistry to constantly develop materials and techniques for oral rehabilitation from a perspective of form, function, and aesthetics. Porcelain, as a dental material with excellent properties as translucency, fluorescence, chemical stability, coefficient of linear thermal expansion and biological compatibility, which justifies its preference. In this context, the application of ceramic laminates has often been recognized as a prominent choice, allowing results that harmonize color and shape, providing an aesthetically pleasing smile. Its application must comply with scientific precepts, with the correct prescription and application of the technique, meeting the specific needs of the patient. The objective of this article is to report a detailed clinical case of aesthetic and functional rehabilitation of the maxillary arch using porcelain veneers and crowns in fixed prostheses. The study aims to demonstrate the effectiveness and applicability of these restorations, in addition to their indications as a treatment option for esthetic rehabilitation. [ABSTRACT FROM AUTHOR]

Objective: To conduct a systematic review with meta-analysis (PROSPERO: CRD42022313303) to analyze studies that evaluated techniques used to obtain impressions in single cases and dental partial fixed, using the intraoral scanning system (intervention) compared to the conventional molding system for prostheses (comparison). Methods: The PubMed/Medline, Cochrane Collaboration, Web of Science and SciELO databases were analyzed using the keywords: "Dental Impression Technique"; "Computer - Aided Design"; "Dental, Partial, Fixed" and "Digital Workflow". The final sample consisted of 13 studies selected for data synthesis. The collected data were tabulated and organized qualitatively and quantitatively using Comprehensive Meta-Analysis software®. The level of significance considered was p<0.05. Results: The main results indicated there was no significant difference between digital and conventional flow for the items: marginal adaptation of the dental prosthesis, choice of method by the professional, patient's decision, and clinical execution time, p>0.05. However, the digital flow showed a significant reduction in laboratory time. Conclusion: Given the data, the digital scanning method is feasible for making single and multiple fixed prostheses compared to the conventional method, with the benefit of reducing laboratory time for its execution. More clinical studies are necessary to evaluate both methods. [ABSTRACT FROM AUTHOR]

This study evaluated the dental prosthesis needs and associated factors in indigenous Brazilian adults from Northeastern Brazil. Dental prosthesis needs were assessed in a representative sample of 225 Indians. Edentulous area and current indication for tooth extraction according to periodontal status or non-restorable condition were registered in a clinical chart. Bivariate and logistic analyses were applied to assess associations of dental prosthesis needs and prosthesis type with age, sex, income, education, smoking, moderate or severe periodontitis, plaque index, dental caries experience, and previous dental visit. Prosthetic treatment was necessary in 83% of the participants. These individuals required 339 dental prostheses, including removable partial dentures (60.2%), fixed (33.6%), and complete dentures (6.2%). Regression analysis showed that age =35 years [odds ratio (OR) 5.95, 95% confidence interval (CI) 1.97-17.91, p=0.002] and caries experience =3 [OR 4.01, 95%CI 1.78-9.02, p=0.001] were significantly associated with prosthesis needs. The type of prosthesis required was associated with sex, age, educational level, periodontitis, caries experience, and plaque index (p=0.03). In conclusion, the need for prosthetic rehabilitation was high in this population, and sociodemographic factors, dental plaque level, caries experience, and periodontitis were associated with the required type of prosthesis. These data can be used to plan the allocation of resources to promote preventive and curative strategies in this population. [ABSTRACT FROM AUTHOR]

Two rare 17th century human prostheses were found during archaeological excavations in Lisbon, one of them exhumed from an inhumation grave in Carmo Church and the other from a well, reused as cesspit, in the Santana Convent. The first corresponds to a thumb distal part, made in silver and the other to four teeth (upper incisors), and produced in ivory, probably from elephant. Since early times most human societies gave huge importance to its members' body aesthetics and bodily conditions. However, those aspects, resulting mainly from economic and social factors, perhaps even religious, would be exacerbated, especially among the political, military and religious elites, from the 16th century onwards, where it was intended to identify the look of each person with their social and material condition.

With the increase in life expectancy, the elderly population has substantially increased. It is estimated that this growth will reach an average of 81.04 years by 2060. Such an aging process contributes to the emergence of diseases. Brazil is the sixth country in the world ranking that constitutes the oldest population and has a high prevalence of chronic diseases. In the country, there are 300 million people with Parkinson’s disease (PD), a neurodegenerative pathology, which due to the loss of dopaminergic neurons, motor, and non-motor symptoms compromises the quality of life of people with this condition. The signs and symptoms of PD compromise motor movements, and these individuals are unable to perform adequate oral hygiene, which favors edentulism because of their susceptibility to periodontal diseases and dental caries. Thus, this case report aims to explain the clinical steps involved during rehabilitation, maxillary and mandibular complete denture in a patient with Parkinson ’s disease and dementia, demonstrating that despite the difficulty during management, the fabrication technique did not differ from that used in a healthy patient. The prosthetic rehabilitation treatment restored the masticatory and esthetic functions, which favored social reintegration and contributed to the improvement in the patient’s quality of life. However, treating patients with PD presents challenges, and not all dentists are prepared to manage this condition. In the inherent limitations during the clinical stages, complete dentures resulted in greater benefits for oral and general health. [ABSTRACT FROM AUTHOR]

Ectodermal dysplasia is a group of hereditary syndromes that presents defects in the development of one or more tissues of ectodermal origin. This study aimed to describe an oral rehabilitation of a patient with ectodermal dysplasia. Performed with fixed and removable prostheses, it returned the function and aesthetics, raising his self-esteem. Patient went for outpatient treatment at the Hospital for Craniofacial Anomalies in the dental prosthesis sector, complaining of esthetics and impaired masticatory function. On intraoral examination, numerous tooth absences were observed due to agenesis and malformation in the few remaining teeth (teeth region 13, 11, 21 23). After the clinical and radiographic examination, the treatment included the manufacture of total crowns milled in elements 11, 13, 21, and 23 (06 elements), with bilateral fittings in the canine region to receive a removable partial denture (class I of Kennedy), placing teeth on the free ends due to the impossibility of installing implants. In the lower arch, the only teeth the patient had were the canines 33 and 43, with the aggravating factor that they were rotated and malformed. A fixed canine-to-canine denture and a removable partial denture for the posterior region were made. [ABSTRACT FROM AUTHOR]

Background: By the use of complete or partial dental prosthesis, function, esthetics, and phonetics are reestablished. Few population-based studies are available in the literature using an older adult population. Objective: Evaluate the use of and need for dental prostheses and their associated factors. Method: This study included a random sample of 287 elderly, in the city of Cruz Alta, Brazil. Use of and need for dental prostheses were the main outcomes, and two analytical models were constructed. Subgroup analyses were performed for individuals using fixed partial denture (FPD) and removable (partial and/ or complete) dental prosthesis (RDP). Results: Use of and need for dental prosthesis were identified in 83.6% (n=240) and 42.5% (n=122) of the elderly, respectively. Women presented a significantly higher prevalence ratio (PR) for use of dental prostheses (PR=1.15; 95%IC:1.02–1.28) and lower need (PR=0.70; 95%IC:0.54–0.91). No statistically significant difference was demonstrated for the use of FPD regarding the sex. Higher education level was associated with lower use of prostheses (PR=0.73; 95%IC:0.58–0.91) when compared to lower level of education. Medium level of education showed a significantly lower need for dental prostheses (PR=0.61 – 95%IC:0.39–0.94). Those that did not consume alcohol presented with a significantly lower use of FPD and RDP (PR=0.46; 95%IC:0.23–0.93 and 0.90;0.81–0.99, respectively). Conclusion: The use of and need for dental prostheses were associated with sex, level of education, and behavioral factors. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to conduct a narrative literature review on the importance and influence of the ferrule effect on the fracture resistance of restorations in endodontically treated teeth with or without the use of intraradicular posts. Methodology: The following descriptors indexed in the DeCS (Health Sciences Descriptors) were used: "Ferrule", Dental Prosthesis", "Dental Restoration Failure", "Post and Core Technique", and "Dental Posts", to search on the databases of PubMed, Embase, Lilacs, Web of Science, Scopus, and Cochrane Library data. Results: Data from most of the in vitro or in vivo studies included in this review suggest the use of the ferrule to increase fracture resistance and longevity of endodontically treated teeth. It has been recommended to make a ferrule with a uniform height of 2 mm and a thickness greater than 1.5 mm. Conclusion: The use of intraradicular posts was indicated by most studies, and fiberglass posts are generally recommended instead of cast metal cores to minimize the risk of root fracture due to the modulus of elasticity similar to dentin, in addition to the possibility of retreatments in adhesive failure cases. Despite this, clinical studies with a long-term follow-up are essential to evaluating the longevity of restorations of endodontically treated teeth using fiberglass posts without or with the presence of ferrule in different thicknesses and heights.

In the oral cavity are several species of microorganisms, some commensals and others that in certain occasions can be pathogenic. Among the most common microorganisms for infections of the oral cavity the fungus of the genus Candida spp. are the most frequent causing a fungal infection known as candidosis. Sampling was done by collecting swab material from the oral cavity of 45 patients with total and / or removable partial dentures, attended at the UNIPLAC Dentistry Clinic and long - term elderly in the city of Lages, Santa Catarina. The study was carried out between September and November 2017. Oral cavity samples were collected with sterile swab and seeded in CHROMagar (CHROMagar, Microbiology, Paris-France) chromogenic medium and incubated at 37°C for 48 hours and colonies identified of Candida spp. through the standard staining characteristics for each species. The positivity for Candida spp. in the oral cavity was 68.89% (31/45), 61,30% were for females and 38,70% for males. The average age of the patients was 65 years. Four yeast species were isolated from the cultivated samples: 54.84% of C. albicans, 6.45% of C. krusei, 3.22% C. tropicalis, only pure samples and 16.12% for C. albicans and C. krusei, 12.90% C. albicans and C. glabrata and 3.23% for C. albicans and C. tropicalis as well as for C. albicans, C. krusei and C. glabrata. The presence of lesions was not frequently mentioned by the patients, and only 4.44% complained of edema or pain and discomfort in the oral cavity. The need for more effective dental monitoring in order to guide patients in a preventive way about the importance of good hygiene and the time of use of the prostheses, since they present conditions of vulnerability to C. albicans infections that can lead to pathological conditions of candidosis.

Introduction : The continued use of dentures and inadequate hygiene may lead to the development of denture stomatitis, a frequent disease in patients who wear dentures and very much associated with Candida spp. Objective : To determine the social characteristics and the care of the individuals with the hygiene of their dentures, as well as the presence of Candida species in patients who wear dentures from a community of Cabedelo Municipality, Paraíba, Brazil. Methods : This is a pilot, cross-sectional, observational and laboratory study with the evaluation of 14 volunteers. Research forms were used and the collection, isolation and identification of the biological material were carried out. Results : The participants had low income and schooling. The daily hygiene of the prostheses, brushing with dentifrice, the non-removal of the prosthesis for sleeping and their use for more than six years were verified in most of the sample. Conclusions : A high presence of Candida spp. in the patients who wear dentures was shown, while C. albicans was the most prevalent species.

A wide variety of dental ceramics is launched every year. Therefore, clinicians should constantly study and update themselves to correctly indicate these materials. This cross-sectional study aimed to assess the association of dentists' academic aspects with their knowledge and the indication of dental ceramics for metal-free restorations. All the dentists from private clinics who affirmed to perform prosthetic treatments on their patients in a Southern Brazilian city were personally invited to this research to avoid dropouts. Participants answered questions related to their knowledge of different dental materials, their information sources and usage frequency of ceramic materials, and related to their academic training/education. Chi-square tests were performed to evaluate the association among the outcomes (knowledge of different materials, information sources considered for material selection and their frequencies of use) and exposure variables (time since graduation and post-graduation degree). Significant associations were also submitted to Chi-square residual analysis. A response rate of 73.3% was reached. The most known and used materials were Y-TZP and porcelain veneered zirconia, respectively, whereas the least known was leucite-based ceramic. The majority of the professionals with at least 25 years since graduation claimed not to know lithium disilicate or leucite-based ceramics, and a significant number of these professionals allow the laboratory prostheses technician to choose the restorative material. In addition, most of dentists with no post-graduation said they did not have knowledge about leucite and lithium disilicate. It was evidenced that continuing education plays an important role in the dentists' attitudes regarding ceramic materials. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Metal-ceramic prosthesis are the treatment of choice in oral rehabilitation because of their high survival rates. However, there are few reports in the scientific literature about factors that lead to fractures of metal-ceramic prostheses. The aim of this study was to evaluate whether prostheses units number, abutment type and number, type of the prostheses, prostheses position in the mouth, bruxism and occlusal plaque influence the incidence of fractures in fixed metal-ceramic prostheses. Methods For this study, 16 patients were selected, totaling 74 metal-ceramic prostheses installed between 2000-2010, with follow up of at least four years. Besides dental history, other information was collected, such as patients’ gender and age, prostheses installation date, and the ceramic system used. In case of prostheses fracture, a questionnaire was applied to identify signs of bruxism. A clinical evaluation was done to evaluate the prostheses integrity and opposing dentition characteristics. Success, failure and survival rates were determined. Results The results showed that the success rate of metal-ceramic prostheses was 87.8% and the survival rate was 89.1%. In addition, the success rate was independent of patient age, prostheses installation time, number of prosthesis, number of prosthesis’ units and abutments. The qualitative variables also did not show significant statistical results between success and failure rates. Conclusion It was concluded that metal-ceramic prostheses have high success and survival rates, what guarantees longevity and indication of this type of prostheses in daily practice.

Self-adhesive resin cements (SARCs) are cementing agents and have the objective of simplifying adhesive cementation, with a simplified use protocol. The aim of this article was to review the literature on SARCs with a focus on the advantages of their use, highlighting their adhesion and biocompatibility mechanism. Thus, the Health Sciences Descriptors "Self-Adhesive Resin Cement", "Dental Cements", "Adhesion" and "Dental Prosthesis" were used, as well as their Portuguese counterparts in the online databases SciELO, PubMed and Bireme in the period of time between the years 2000 to 2020. According to the studies, SARCs have excellent physical and mechanical properties, which include low solubility in the oral environment, adhesion to the dental substrate and the prosthetic part, color mimicry, biocompatibility and fluoride release, in addition to being applied in a single step, optimizing the operator's working time. In addition, self-adhesive cements seem to offer a promising new approach in indirect restorative procedures, which may present a performance similar to conventional ones, however more studies are needed to support their long-term applicability.

This study aims to investigate the extent to which the use of dental prosthesis influences the nutritional intake of the elderly, and to understand the sociodemographic indicators that condition the demand for dental treatment, as well as the use and type of dental prosthesis. Methodologically we proceeded to a cognitive evaluation, a questionnaire identifying the elderly, application of the Geriatric Oral Health Assessment Index tool and a food anamnesis were carried out in a sample of 400 elderly people from three Portuguese districts. There was a correlation (p=0.006) between the level of schooling and the periodicity of dental visits, as well as an association between gender and use of dental prosthesis (p=0.000), between prosthesis use and schooling level (p = 0.007) and between the type of dental prosthesis and yield (p<0.05). Statistically significant differences were observed in the daily intake of iron (p = 0.014) and phosphor (p = 0.042) in individuals with and without dental prosthesis, and differences in the daily intake of total protein, vitamin A, carotenes, α- tocopherol and magnesium (p<0.05) when compared to different types of dental prostheses. It is concluded that the level of education and gender condition the demand for dental treatment. The use of prosthesis affects the daily nutritional supply of iron and phosphorus.

In oral rehabilitation, the technological innovations are imports that came from engineering, physics and chemistry and were adapted to Dentistry. It is up to the prosthodontics specialists to reestablish the patient's oral function, and improve health and aesthetics. But in order to fulfill these requirements, technological support is necessary, among them we can highlight 3D printing. This study aims to review within literature, the main additive manufacturing technologies used in dentistry, as well as their applicability in oral rehabilitation. The methodological approach employed consisted of research carried out on search engines such as PubMed and Google Scholar. The online databases were employed in order to find works published in Portuguese and English from 2010 to 2020. Through this study we can conclude that additive manufacturing technologies are a reality within dental practice. 3D printing has enabled the making printed casts for diagnostic purposes or definitive casts, implant drill guides, castable patterns, custom impression trays and occlusal splints in an agile and completely digital way, consequently reducing the possibility of human error.

Um fator etiológico da doença periodontal é o biofilme. Pelo seu acúmulo, ele pode desencadear fatores de retenção locais, dentre eles estão as próteses parciais removíveis (PPRs). A função desse aparelho protético é substituir os dentes ausentes em pacientes desdentados parcialmente. A relação entre periodontia e prótese dentária na construção de um plano de tratamento integrado permite a manutenção da função da reabilitação protética, com boa expectativa de duração do tratamento. Esta revisão tem como objetivo analisar os estudos científicos presentes na literatura, que relacionem a prótese parcial removível e a doença periodontal. Foram selecionados artigos nas bases de dados eletrônicas PUBMED e Biblioteca Virtual da Saúde (BVS) no período de 2000 a 2018, nos idiomas português, inglês e espanhol. Foram utilizados termos em inglês indexados no Medical Subject Heading Terms (Mesh Terms –MESH) para o PUBMED e termos em português indexados nos “Descritores em Ciências da Saúde” (DECS) para a plataforma BVS. Os estudos analisados mostraram que a PPR aumenta o risco de desenvolver doenças periodontais, dentre elas: periodontite e gengivite. O aumento do risco está relacionado à negligência na higienização e ao planejamento indevido da PPR. Sendo assim, a associação de uma terapia periodontal com o controle de biofilme adequado e periódico em interface a um planejamento e adaptação da PPR pode ser uma boa alternativa para se evitar danos ao remanescente dental e ao periodonto.

Introduction: The use of complete dentures has an impact on oral health-related quality of life. Elderly people are the population sector to be researched into from this perspective. Objective: Evaluate the self-perception of the impact of the use of complete dentures on the oral health-related quality of life of institutionalized elderly people. Methods: The study sample was 20 elderly people from Lar dos Idosos Recanto do Tarumã, Curitiba, Paraná, Brazil. Evaluation of demographic and economic details, habits and clinical aspects was based on the information collected with the Geriatric Oral Health Assessment Index questionnaire. The data were subjected to descriptive and bivariate analysis (Chi-squared test), with a significance of 5%. Results: Mean age was 75.2 (SD = 8.8) years and mean time of denture use was 27.9 (SD = 18.5) years. Income was below minimum wage in 80.0% of the participants, whereas the last visit to the dentist had occurred more than a year ago in 70.0%. The worst reports had to do with chewing, represented by problems to chew food and discomfort when eating, with 25% positive answers to each question. The sum of the frequencies of the answers "sometimes" and "always" about dissatisfaction with or unhappiness about the appearance of the mouth was reported by 60% of the respondents. Unsatisfactory retention of the lower denture occurred in 50.0% of the cases, whereas occlusion problems were present in half of the sample. Defects were present in 70.0% of the upper dentures and 45.0% of the lower dentures. No significant association (p> 0.05) was found between independent variables and outcome. Conclusions: The elderly people evaluated, regardless of the conditions of their complete dentures, reported satisfactory oral health-related quality of life.

ABSTRACT CAD/CAM Systems emerge as one of the greatest innovations in contemporary dentistry. Through digitalization, the virtual planning and the manufacture of prosthetic parts, the simplification and optimization of the rehabilitator treatment occurred. The aim of this study is to approach the technique of CAD/CAM use, its main characteristics, advantages and disadvantages when used in dental prosthesis. A literature review was conducted through the search for studies attached in the databases: Bireme and Pubmed, published between 2003 and 2018 years. Among the advantages of using CAD/CAM systems, we can highlight the best reproducibility and accuracy, shorter manufacturing time, besides the possibility of using more resistant ceramics and making restorations with this material. The main disadvantage reported is still the high cost of the equipment. CAD/CAM technology in order to automate and streamline the process of making prostheses, being able to produce high quality parts with a huge variety of materials. Nevertheless, the technique should be adjusted based on the needs of the materials to be used and the preferences of the dentist and technician in dental prosthesis.

Introdução: O envelhecimento da população aumenta a necessidade de reabilitação protética e o custo do atendimento odontológico. Para reabilitar com qualidade e baixo custo é necessário conhecer os materiais odontológicos desse processo, como os materiais de moldagem. O mais utilizado no Brasil é a silicona de condensação, que possui limitações. Porém, o fabricante modificou a fórmula com o intuito de melhorar a estabilidade dimensional. Objetivo: avaliar a estabilidade dimensional da silicona de condensação Speedex com a nova tecnologia DCP, em diferentes tempos de vazamento nas moldagens para prótese fixa. Material e métodos: Foi confeccionado um modelo padrão metálico com dois cilindros de mesmos diâmetros e mesma altura para simular uma prótese fixa. Foi elaborada uma moldeira metálica padronizada com retenções e guias de inserção. A partir dessa, outras quatro, em acrílico incolor, foram reproduzidas pelo alginato reversível. No total, foram realizadas 20 impressões, sendo 5 impressões por grupo. Os grupos foram vazados com o gesso tipo IV em diferentes tempos: grupo 1 (n=5): imediato; grupo 2 (n=5): 30 min; grupo 3 (n=5): 36h; grupo 4 (n=5): 72h. O modelo padrão e todos os modelos de gesso do grupo 1, 2, 3 e 4 foram medidos por dois pesquisadores de forma cega com auxílio de um paquímetro digital. Foram analisadas as distâncias externas e internas entre os pontos de referência dos cilindros. Os grupos foram comparados pelo teste t de Student, o nível de significância considerado foi p0,05). Não houveram diferenças entre os grupos 1 e 2 e 1 e 3; porém houve diferença significativa entre o 1 e 4. Conclusão: A silicona de condensação Speedex, não altera a estabilidade dimensional com o vazamento em até 36 horas.

The search for a harmonic smile, and absolutely perfect, elevates the level of requirements and perspective of the patients. The ceramic laminates have become conservative alternative for these rehabilitations due to its biological, chemical, mechanical and aesthetic principles. This article presents a multidisciplinary approach to the rehabilitation minimally invasive technique, through a literature review, conducted using scientific papers written in Portuguese and English from 2009 to 2019, in the database of SciELO, LILACS and PubMed, with the following descriptors: oral rehabilitation, dental prosthesis, dental veneers and ceramics. The paper presents the indications, advantages, disadvantages and operative steps for the dental contact lenses, which have shown to be increasingly imperceptible, with results aesthetically and functionally satisfactory. However, it is necessary to have a proper planning, good technique and clinical care to obtain excellent results. [ABSTRACT FROM AUTHOR]

Introduction: cobalt chromium and chromium nickel alloys are the most used in the manufacture of dental prostheses due to their biocompatibility, high mechanical properties, market availability and reasonable costs; However, the metallic residues of these alloys generated in dental laboratories go to waste without proper disposal, giving rise to environmental problems because they are heavy metals whose particles do not disintegrate neither chemically nor biologically and remain in the environment Corresponding author: Received: 01/16/2020 Accepted: 12/14/2020 for several years, decontamination methods are expensive and long-term, therefore, these residues are dispersed in the ecosystem through leachates that contaminate soil, water and air, reaching the food chain and affecting the health of the population. Objective: to recycle surplus cobalt chromium and chromium nickel alloys generated in the manufacture of dental prostheses. Materials and methods: experimental study resulting from applied research. The metal waste was carried out, the recycled material is weighed, labeled, packed in plastic bags and supplied to Results: a decrease in metal surpluses generated in the production of prostheses was obtained metal waste generated / 6 Kg of recycled material = 1.2. The recycled material was supplied to those for the learning processes of casting and casting of dental prostheses, it allowed to elaborate instruments that serve in the daily work of the dental laboratory such as welding bars and keys for implant screws, which have a high cost in the market. Conclusions: recycling plays a fundamental role in preserving the environment, allows the reduction of electrical energy consumption, the reduction of greenhouse gases, the reduction of soil, air and water pollution. This project made it possible to generate environmental awareness in the students of the program, reduce and take advantage of the metallic surpluses generated in the manufacture of dental prostheses and thus contribute from the profession to sustainable development and environmental quality.

For a long time, dental surgeons have sought a definitive solution to the functional and aesthetic problems of edentulous patients. Several dental implant systems were developed over the years, each one with its advantages. But when the different systems are compared biologically, the maintenance of peri-implant tissues is superior in the Morse taper implant when compared with the Internal Hexagon and External Hexagon (EH) systems. The objective of this paper is to analyze the mechanical behavior of different dental implant systems. For this bibliographic search it was employed an indirect documentation technique, where it used secondary sources of information. Many studies followed the different implant systems for up to 15 years, finding several mechanical flaws in implants, abutments and prosthetic screws. One of the first studies with dental implants followed 1997 implants for 15 years, which the authors found fractures, at different levels, of 3.5% of the implants, the majority occurred after 5 years of follow-up, possibly due to marginal bone loss. To limit the mechanical failures found in EH implants, the researchers tested other connection systems to use in dental implants. In this study, is possible to conclude that the ideal is that the implant and the prosthesis are designed in such a way that there is a distribution of loads in the bone tissue, that can be achieved through of an adequate three-dimensional adjustment of the implant.
