The aim was to review the literature and discuss the occlusal concepts in oral rehabilitation with complete dentures, emphasizing the advantages and needs of each occlusal scheme. A search was carried out on the databases PubMed, SciELO, Google Scholar and in textbooks, using "Dental Occlusion"; "Dental Occlusion Balanced"; "Canino guidance"; "Denture complete"; and "Denture design" as keywords and the Boolean operators AND, OR, and NOT. Among the occlusal schemes available for prosthetic planning, the bilateral balanced occlusion (BBO) and the canine guided occlusion (CGO) were the most studied and discussed in the disocclusion of complete dentures. Studies indicate the type of occlusion can interfere with muscle activity of the stomatognathic system, masticatory efficiency, bone resorption, retention and stability of removable dentures, and patient satisfaction. In the literature examined, the recommendation of the CGO as the preferred occlusal scheme in the planning of complete dentures was noticeable. The results of the studies indicate less muscle activity during mastication, better retention, and stability of the total denture. It is simpler and easier to obtain this occlusal scheme than the BBO. CGO benefits phonetics; it is aesthetically preferred by patients; and, in terms of quality of life, self-perception of masticatory and occlusal strength, has shown to be satisfactory. We conclude that CGO can be recommended as a favorable occlusal scheme for oral rehabilitation with complete dentures. [ABSTRACT FROM AUTHOR]

Objective: To conduct a cross-sectional analysis of the sociodemographic and clinical profile of edentulous bimaxillary patients and their habits of using old complete dentures (CD). Subsequently, the participants were rehabilitated with complete dentures, in three years (2017-2019), in three municipalities located in the state of Pernambuco, - Brazil, through a university extension program. Methods: We evaluated a total of 58 participants through a questionnaire with 73 questions. Data collected were used for quantitative assessment, and the level of significance was set at 0.05. Results: Most of the participants were elderly patients with an average total edentulous time of 24.3 ± 15.3 years, and 22.14 ± 14.22 years at the maxilla and mandible, respectively. In addition, there was a high prevalence of users who had bimaxillary prostheses (74%). In 57.1% of the sample, there was a predominance of brushing with toothpaste, 42.9% used soap/detergent, sodium hypochlorite solution, and (or) sodium bicarbonate as adjuvants in cleaning. Moreover, 66.6% of the patients needed a clinical intervention for CD repairs. About the harmful habits, the elderly showed a less frequent habit of sleeping with their prostheses compared to the adults (p ≤ 0.001). Conclusion: Most of the participants were female with an average age of 63 years. They presented an average of 20 years of edentulousness (maxilla and mandible) and the extended use of the dentures (> 10 years), in addition to the habit of continuous use. More than half of the participants used inadequate cleaning methods. [ABSTRACT FROM AUTHOR]

Individuals with different functions such as the functions of the stomatognathic system (SE), such as decreased chewing capacity, phonetic alteration and aesthetic impairment. The prosthetic oral rehabilitation assumes a function of great importance for the patient with prognosis, being able to be paramount for general health and quality of life. Rehabilitation as functions of SE and reinserting the individual into the social environment. Objective: to establish a prosthetic technique performed with no intention to promote the prognosis of a person over a series of years after the creation of a conventional molding technique. Methods: This is a case report, reporting a volunteer patient who needs a new total prosthesis. Clinical and laboratory stepswere used. Results: It as found to improve the retention, stability and aesthetics of the device as an improvement in patient occlusion. Conclusion: An issue that maybe easier to correct on a large scale in the chewing and phonation functions is greater than the disadvantages to dental discrepancy of the inter-arch size present in prognostic patients.

Introduction: overdentures are removable, muco-implantsupported, complete dentures, stabilized by elements installed on residual roots or implants. A variety of docking systems have been used to support overdentures, including bar-clip systems, balls, magnets and telescoping crowns. Objective: to evaluate, through a literature review, the overdentures retained by bar-clip system, exposing a correct planning, as well as describing protocols of making such devices. Methods: a literature review was carried out in the databases of the Latin American and Caribbean Center on Health Sciences Information (LILACS), Medline, Brazilian Dentistry Bibliography (BBO), the virtual library (SCIELO) and the collection of books from the University of Passo Fundo/RS (UPF). Literature Review: the bar-clip system consists of a plastic bar for casting or already metal and a retention clip. In some situations, the clip-on system is more suitable than other systems, although it has limitations in certain clinical scenarios. The bar-clip system allows considerable retention and stability, resulting in a restoration of the masticatory function, greater safety and great patient satisfaction. Final considerations: most of the studies showed an improvement in the quality of life related to the oral health of the patients after treatment with overdenture compared to the conventional total removable prosthesis.

Introduction: the odontological records are the documents kept during the treatment. It offers data about both the patient's anamnesis and theirs pre-existing conditions, as well as the planning and all the work already done. Objective: identify, by way of analysis of the records, all information obtained about the patient's profiles and the work offered in dental prosthetics in a center dedicated to odontological specialties in a city in the countryside of Bahia State both in 2016 and 2017. Methodology: this study refers to a retrospective observation of cross-sectional cuts, descriptive and analytic, with the purpose of making a full analysis of the patients' records of the patients treated at the Centro de Especialidades Odontológicas na Bahia (Center of Odontological Specialities at Bahia). Results: the results showed a higher frequency of female, age from 61 to 65 years, with systemic pathologies. The upper and lower total edentulism was more frequent, and the mean time to complete rehabilitation was 6 months. Conclusion: the analysis of the odontological records is the most efficient way of obtaining all the needed information of the users and the quality of the services provided. A file well-filled offers to the professional every detail of each patient, ensures an excellent and tailored clinical work. [ABSTRACT FROM AUTHOR]

Introduction: the dental total prosthesis is an artificial organ that should promote health and quality of life. The way of use, conservation and hygiene is fundamental for the success and longevity of it. One tool that seems to be effective in detecting and disseminating this type of information is activities of University extension. Objectives: to analyze the level of knowledge about the use of complete sets of dentures and their conservation in a low-income population through a cross-sectional epidemiological study. Methods: This research had a convenience sample of 37 users of complete sets of dentures. Data was collected using a questionnaire applied by two trained examiners. The data were interpreted via descriptive and statistical analysis (tests of Kruskal-wallis e Kolmogorov -- Smirnov/ p = 0,05). Results: The average income of the sample was R$ 668.00. The average time of denture use was 7.3 years; 70.27% of the patients sleep with their dentures, and 83.78% of them sanitize the dentures with a toothbrush and toothpaste. Conclusion: Regarding the variables association, we noticed tendencies yet to be explored in the habits of the complete denture wearer. Moreover, we conclude that the population's level of knowledge on the subject needs to be improved. Thereby, once these conditions are detected and transmitted to government officials, the extension project through the research tool will be able to assist government's course of action regarding oral health.

Introduction: the total dentures are aimed at preserving the function of the stomatognathic system of the fully edentulous patient. However, in the oral mucosa may appear manifestations whose main cause are the totally unsuitable dentures. Objective: this study aims to investigate the proliferation of tissue lesions caused by removable dentures by impregnation method for silver (AgNOR), thereby facilitating the treatment and determining the prognosis of the lesions to be studied. Methodology: we selected all cases of oral lesions most commonly associated with the use of dentures recorded in Histopathological Diagnostic Service ICB-UPF in the years 2012 and 2013, having been found 5 cases of pyogenic granuloma, 5 cases of hyperplasia, 5 cases of irritation fibroma and 2 cases of peripheral ossifying fibroma. Histopathological lesions cuts were impregnated by silver (AgNOR method), having been obtained with the aid of the program Image Tool®, the number of NOR cells 100 in each case, resulting in an average NORs in every group of lesions. Results: the results were tabulated in a spreadsheet and comparing the average number of NORs of each group was conducted through ANOVA, 5% significance level. Results: The group of hyperplasias showed average of 2.41 NORs per nucleus, the group of pyogenic granulomas showed 2.44, the irritation fibroma 2.22, and peripheral ossifying fibroma showed average of 1.89 NORs for cell nucleus, differing significantly from that of the aforementioned lesions (p = 0.002). Conclusion: the peripheral ossifying fibroma proved the injury caused by removable dentures with lower cell proliferative activity. This study needs to be complemented by future clinical studies.

The dental profession is facing an increase in size and age of the older population. In addition, there is a large number of older people who is completely edentulous. Edentulism can substantially affect oral and general health as well as overall quality of life. The purpose of this article was to investigate in dental literature the relationships among denture wearing, oral health status and general health conditions in elderly people. Chronic disease, psychosocial and physical dysfunction and complex pharmacotherapeutic regimens are prevalent in older people. The last ones may have many adverse effects on the oral health and on the general health of the elderly. In this context dentists must evaluate the oral health status of the elderly and its relationship with the general health and the overall quality of life. [ABSTRACT FROM AUTHOR]

A reabilitação dos pacientes desdentados é uma grande preocupação para a Odontologia, por isso, muitos trabalhos mencionaram a redução das habilidades mastigatórias desse tipo de pacientes. Trabalhos mais recentes definiram as habilidades mastigatórias, diferenciandoas em: nível de satisfação (NS), capacidade (CM), eficiência (EM) e performance mastigatórias (PM). Este trabalho foi idealizado com o objetivo de comparar as habilidades mastigatórias de pacientes desdentados e dentados. Foram selecionados 10 pacientes desdentados reabilitados com próteses totais da Universidade do Sagrado Coração (USC) -- Bauru e 10 pacientes dentados entre 41 e 64 anos. Para o teste da EM, os pacientes mastigaram amêndoas até sentirem que elas estavam em condições de deglutição, num período de 10, 20 e 40 segundos. O conteúdo foi recolhido e colocado num sistema de tamises, peneiras com orifícios de diferentes diâmetros, e avaliado a EM como ótima, boa, regular, ruim e péssima por meio de uma classificação pré-estabelecida. Para o teste da performance, utilizou-se um simulador de alimento em que o paciente foi orientado a realizar 40 ciclos mastigatórios, utilizando o mesmo sistema de tamises. A capacidade foi avaliada, por meio de um questionário, com base em dados fornecidos pelos pacientes, assim como o nível de satisfação. Os pacientes dentados apresentaram 92,5% da EM, 97,5% da PM, 100% da CM e 99,5 % do NS, enquanto os pacientes desdentados apresentaram 25% da EM, 17,5% da PM, 57,86% da CM e 67% do NS. Os pacientes que utilizam prótese total apresentam-se com todas as habilidades mastigatórias bastante inferiores aos pacientes dentados. [ABSTRACT FROM AUTHOR]

O sucesso e longevidade dos tratamentos reabilitadores dependem de diversos aspectos, um deles é a qualidade de higiene do paciente pós-instalação da prótese. Um dos tipos de próteses é a protocolo, sendo ela uma prótese total suportada por implantes, ela oferece muita segurança e conforto ao paciente, porém exige visitas periódicas ao dentista para realização de ajustes, manutenção e higiene. Este trabalho relata um caso clinico no qual a paciente fazia uso de próteses protocolos superior e inferior e apresentava dificuldades para realizar a devida higienização. A paciente foi atendida na clínica do projeto de extensão em Implantodontia no Centro Universitário Sagrado Coração (Unisagrado), além da dificuldade de higiene, ela relatou ardência no rebordo superior. As próteses implantossuportadas foram removidas e a limpeza interna dela foi realizada com jato de óxido de alumínio. A fim de melhorar o espaço para que a higienização fosse realizada de modo eficiente, a prótese protocolo superior foi substituída por uma nova, garantindo o espaço adequado para limpeza e desse modo, melhorar a condição de saúde bucal.

Há necessidade de um protocolo clínico para indicação de diferentes técnicas de moldagem para paciente edêntulos. Por isso, este projeto teve como finalidade conduzir uma revisão sistemática a fim de estudar os dados clínicos de diferentes técnicas usadas para moldagem de pacientes em prótese total. As bases de dados PubMed/Medline, Cochrane Collaboration, Web of Science e SciELO foram analisadas utilizando unitermos relacionados: "Complete denture"; "Impression techniques"; ":material, dental impression". Os dados dos estudos selecionados foram coletados, tabulados e organizados qualitativamente e quantitativamente utilizando o software: Comprehensive Meta-Analysis. O nível de significância considerado foi de p<0.05. Os principais resultados quantitativos apontaram que, comparando o número de consultas controle para obtenção de uma prótese total entre os métodos convencional vs. o método simplificado, assim como quando mensurado a qualidade de vida do paciente, não houve diferenças significativas. Portanto, diferentes métodos clínicos podem ser viáveis para obtenção da prótese total, especificamente, comparando métodos de moldagem convencional vs. simplificado. Dessa forma, a técnicas simplificadas de confecção de prótese total podem ser úteis, pois reduzem o tempo de tratamento e custo financeiro, sem prejuízos para qualidade de vida do paciente.
