In this study we tested two different type of implant systems that were selected on the basis of differences in macrogeometry of platform switching in order to evaluate the behavior in term of BIC on the platform.The patients were divided in two groups (Group I and II); group I was composed by 4 patients that each received in the posterior areas of mandible one type A implant (3,6 mm in diameter and 6,5 mm in length GTBPlan1Health Amaro (UD) Italy) one type B implant (4 mm in diameter and 8 mm in length OsseoSpeed Astra Tech, Dentsply Molndal, Sweden). Group II was composed by 3 patients that each received in the posterior areas of jawsbone one type A implant [3,6 mm in diameter and 6,5 mm in length GTB- Plan1Health Amaro, (UD), Italy] one type B implant (4 mm in diameter and 8 mm in length OsseoSpeed Astra Tech, Dentsply Molndal, Sweden). All the implants were placed, by the same operator, in equicrestal position using "one stage" technique with a healing abutment at an adequate gingival height. After 12 weeks of healing all the implants of both groups were harvested with the peri-implant bone tissues. BIC upon platform was calculated considering as implant surface the platform length.Our results showed that the mean percentage of BIC value related to platform surface placed in equicrestal position was higher in patients with type A implant than patients receiving type B implant independently from mandibular or maxillary positions. Moreover the mean percentage of BIC related to platform surface was significantly (p0.05) higher in Group II/A than Group I/A.Our data highlights that the particular features of the Bioplatform of Type A implant systems guarantee a higher value of BIC even if the implants were placed equicrestally.

The amount of marginal bone loss is considered an important criterion to evaluate the implant therapy outcome and to predict the prognosis of the implant rehabilitation. The purpose of this systematic review was to examine the available literature comparing clinical and radiological outcomes like the implant failure rates and marginal bone loss around platform switching dental implants

The objective of this study was to compare different approaches temporary restoration in an immediate implant placement. To determine the respective influence of each parameter, two treatment groups were formed; a strict and standardized study protocol was applied to minimize the influence of bias and confounding factors. The Pink Esthetic Score (PES) - the esthetic out-come of soft tissue appearance was evaluated.Sixteen patients with a single failing tooth in the maxilla and a natural contralateral site were randomly distributed into two groups. Treatment variations affected the provisional restorative in detail, group 1 with immediate implant placement and immediate temporary restoration with the simulation of the first three mm of the root and the seal of the socket, group 2 with immediate implant placement and immediate temporary restoration without the seal of the socket. All patients received the final prosthetic restoration 10-12 weeks after implant placement. Standardized photographs were taken eight months after tooth extraction. Five competent observers analyzed the esthetic outcome according to the PES.The overall scores of the four treatment groups revealed PES values of 8.47 (SD 2.08, group 1), 6.62 (SD 3.24, group 2). The differences between groups 1 and 2 and were statistically significant (P=0.015 and P=0.047). The single parameter analysis displayed a certain range of fluctuation and heterogeneity.Immediate implant placement and restoration appear to be a suitable alternative to early implant placement if an experienced surgeon is entrusted with the implantation procedure.

Many factors could affect the osseous healing of implants such as surface topography of biomaterial, the status of the bone/implant site, implant loading conditions, surgical technique and implant design. The aim of this study was to analyze the BIC of 2 different implants systems characterized by different micro and macrogeometry, that were placed in the posterior maxillary and mandibular jaws of humans, clinically unloaded and retrieved for histomorphometric analyses after 12 weeks.The patients were divided in two groups (Group I and II); group I was composed by 4 patients that each received in the posterior areas of mandible one type A implant [GTB-Plan1Health Amaro (UD) Italy] one type B implant (OsseoSpeed Astra Tech, Dentsply Molndal, Sweden). Group II was composed by 3 patients that each received in the posterior areas of jawsbone one type A implant [GTB-Plan1Health Amaro (UD) Italy] one type B implant (OsseoSpeed Astra Tech, Dentsply Molndal, Sweden). After 12 weeks of healing all the implants of both groups were harvested with the peri-implant bone tissues. Osseointegration process was evaluated throughout measurements of BIC.No statistical significance differences were found among the mean percentage of BIC of Group I - type A were 66,51%Our results highlight that the mean percentage of BIC after 12 weeks from the implants placement without functional loading is not influenced by the composition of the implant surface.

Skin disorders are an important problem in children living in developing countries, but only a few epidemiologic investigations on pediatric dermatoses are available in the literature. Our study is an analysis of the range and frequency of skin diseases presenting to the Italian Dermatological Center in a pediatric Ethiopian population. A retrospective analysis was performed on 17,967 medical records of children aged 0 to 18 years attending the Italian Dermatological Centre in Mekele (Ethiopia) from January 2005 to December 2009. Infections and infestations accounted for 47% of the disorders seen; fungal infections were the most common (44.1%), followed by bacterial and parasitic diseases. Dermatitis constituted the second most common diagnostic category (24.7%) of the disorders seen, and contact dermatitis was the most common diagnosis (48.8%). Pigmentary disorders and disorders of skin appendages were more common in girls, whereas fungal and parasitic infections were more common in boys. Bacterial and parasitic infections were more common in children younger than 1 year old, fungal infections in those aged 1 to 5.9, and disorders of skin appendages and pigmentary disorders in those aged 15 to 18. These findings demonstrate that most of the disorders seen could be easily managed in clinical practice with appropriate skill development. It is crucial to ensure that training of medical students and pediatricians focuses on accurate recognition, diagnosis, and management of these common skin diseases and that families, teachers, health workers, and nurses be educated about the most common signs of prevalent skin diseases to help facilitate appropriate care.

Purpose. The surgical-orthodontic treatment of impacted maxillary canine (IMC) remains a challenge to today’s clinicians. The aim of the present paper is to describe an unconventional treatment of IMC with insertion of implant into the retained canine and 3 years follow-up. Case report. A 55-year-old female patient attended to rehabilitate her maxillary left canine site. An unconventional approach was proposed to the patient. A large diameter tapered implant (Ø 5 x 18 mm) was inserted (Nobel Active, Kolten, Swisse). An immediate loading prosthetic rehabilitation was performed. After checking for implant stability the prosthetic steps were carried out and a single crown was delivered with Procera system. Conclusion. The patient was happy of this kind of single non-invasive session for treating IMC. At the 3-year control, the implant did not show any mobility or signs of peri-implantitis clinically or radiographically. In addiction patient was satisfied of aesthetic results

Spiral dental implant (SDI) is an implant with a conical internal helix that confers the characteristic of self-drilling, self-tapping, and self-bone condensing. These proprieties offer better control during insertion of SDI giving a high primary stabilization, even in poor quality bone. A shorter diameter of SDI results in reduced drilling during insertion and consequently less trauma and minimal bone loss. To address the research purpose, the investigators designed a retrospective cohort study. The study population was composed of 25 patients, 11 males and 14 females that have been treated by Dr. Balan with 187 SDI positioned in mandible and into maxilla bone. The implants were placed during the years 2013 to 2014 in Dr. Balan clinic. All patients underwent the same surgical protocol. Several variables are investigated: demographic (age and gender), anatomic (upper/lower jaws and tooth site), implant (length and diameter and type) variables, edentulism (partial or total), and comorbid status of health (i.e.: hypothyroidism, parodontitis, hypertension, diabetes, presence of cancer, heart disease, hepatitis and rheumatologic disease). Pearson Chi-Square test was used to investigate variables and p < 0.05 was considered statistically significant. Statistically it has been shown that females have a higher possibility of unsuccessful respect of male, with a "p value" of 0.014. Another important impact factor for success of implant insertion has been represented by concomitants pathologies: cancer represents the most negative high factor risk with a percentage of unsuccessful of 50%, followed by heart disease (15%), and diabetes (3.7%). SDIs are reliable tools for difficult cases of oral rehabilitation. They have a higher success and survival rate, which means stable results over time. No differences were detected among SDI lengths, implant/crown ratio. In addition, the insertion of SDIs in banked bone can be performed without adverse effects. Finally, flapless and computer tomography-planned surgery does not significantly increase the clinical outcome of SDIs in complex rehabilitation. Cancer represents the most important variable to consider when a patient wants to do oral rehabilitation because of its high risk of unsuccessful.

The histological and histomorphometrical examination were the gold standard in the qualitative and quantitative analyses of the peri-implant tissue around the implant. In recent years, the field of microscopy has witnessed a considerable enhancement of the performance of microscopes that have very high resolution performance and allowing very sophisticated analysis even larger than traditional preparations. The possibility to have an affordable analyses of whole implant with the surrounding different tissues (soft and hard tissues) without the traditional pre-treatment necessary for the histological analysis may represent a goal to describe material properties and behaviors or simply to visualize structural details. The aim of the present study were to evaluate a 3D X-ray microscopic analysis of peri-implant tissue compared to a traditional histological and histomorphometrical analysis of the peri-implant tissues around an implant with a conical connection associated with platform-switching in order to assess the validity of the new analysis technique.

Questo saggio delinea un percorso che parte dal problema della costruzione delle opinioni o credenze. Riprendendo Peirce, il realismo si rileva implicito nel metodo scientifico e conduce a una posizione pragmatista. Il pragmatismo viene porta all'idea di progetto come paradigma di un fare sociale e politico. Il pragmatismo appare, nell'opinione dell'autore, una posizione più feconda del realismo negativo come esemplificato tra gli altri da Umberto Eco.1 Si presenta brevemente, a tal proposito, il nuovo pragmatismo nella teoria di uno dei maggiori rappresentanti, Richard Sennett. Infine, una breve conclusione rilancia alcuni concetti di una semiotica dialogica, pragmatica e progettuale.

Il saggio traccia una mappa storico-teoretica dell'evoluzione dei rapporti tra il movimento pragmatista e la filosofia europea del primo e secondo Novecento, ponendoli a confronto con le riprese statunitensi( in particolare Putnam e Rorty) dei temi cruciali della filosofia di Peirce, James, Dewey e Mead. Non è possibile comprendere pienamente l’evoluzione e le vicissitudini del pragmatismo senza fare riferimento alla filosofia analitica, e viceversa. Si tratta di due prospettive che, nonostante non siano mancati conflitti anche profondi, si sono nei fatti intrecciate, contribuendo l’una alla storia dell’altra. Questa la cornice di un‘analisi allo stesso tempo teoretica e storica, che mette in luce come proprio le interazioni fra i due punti di vista abbiano permesso di pensare in modo nuovo problemi e tematiche tradizionali. A partire dagli anni Sessanta, il pragmatismo ha vissuto una rinascita sia negli Stati Uniti sia in Europa, tanto che è diventato usuale parlare di “svolta pragmatica” della filosofia contemporanea. Questo saggio introduttivo puntualizza le figure chiave di tale cambiamento: Apel e Habermas, Putnam e Rorty, Quine, Sellars e Davidson, i cui contributi su temi come la verità, l’intersoggettività, il realismo sono consapevolmente debitori rispetto alle prospettive dei pragmatisti classici. The essay traces a historical-theoretical map of the relationships between pragmatist thought and European XXth century philosophers, comparing them with the most influential American reinterpretation of pragmatism's pivotal issues. It is impossible to fully understand the development and vicissitudes of pragmatism without referring to analytical philosophy, and vice versa. The two perspectives, in spite of the many and even deep conflicts, have in fact interwoven, each contributing to the history of the other. This is the framework for an inquiry which, on a theoretical as well as historical level, sheds light on how the interactions between the two standpoints have allowed to approach traditional problems and issues according to new criteria. Starting from the Sixties, pragmatism has lived a revival both in the United States and in Europe, insomuch as it is now very common to speak of a “pragmatic turn” in contemporary philosophy. This introductory essay pinpoints the key-figures of that change: Apel and Habermas, Putnam and Rorty, Quine, Sellars and Davidson, whose contributions on themes such as truth, intersubjectivity, realism are consciously indebted to the perspectives of the classical pragmatist.

The essay argues that there are interesting overlappings between the pragmatist tradition and the theses of the liberal forms of naturalism (which oppose the most common form of scientific naturalism).
