Titanium alloys are widely used in dental implants in virtue of clinical evidences of the excellent biocompatibility performance shown by this alloys. However, there are still a number of unanswered questions regarding the ideal physicochemical properties of titanium surfaces use...

Parafusos de pilar utilizados em implantes dentários / Pillar screws used in dental implants

Due to the surge and success of bone integrated implants, dental implants have been consolidated as an important rehabilitation technique within the general context of dentistry. Functional force, bio-mechanical compatibility and tension transfer to the neighboring tissues are am...

Analysis of intercurrences and complications interfering in the placement and primary loss of osseointegratable dental implants a retrospective study / Análise das intercorrências e complicações interferentes na instalação e perda primária dos implantes dentais osteointegráveis - um estudo retrospectivo

Intrinsically, every surgical procedure presents a certain rate of associated intercurrences and/or complications. Hemorrhages, infections, paresthesias or dysesthesias and primary loss of implants are some of the most common intercurrences and complications related to surgical p...

Electrochemical behavior of three CP titanium dental implants in artificial saliva

The electrochemical behavior of three titanium dental implants purchased on the Brazilian market was evaluated in artificial saliva using open-circuit potential measurements, electrochemical impedance spectroscopy and potentiodynamic polarization. The three implants are passive i...

Virtual planning and construction of prototyped surgical guide in implant surgery with maxillary sinus bone graft

PURPOSE: To evaluate the efficacy of associating techniques of bone grafting in the maxillary sinus with the use of a prototyped surgical guide for planning and positioning dental implants in total edentulous maxillae, rehabilitated after six months. METHODS: Eight patients conse...

Analise histologica e histomorfometrica do reparo osseo perimplantar em cães submetidos a instalação de implantes endosseos com um modelo de carga precoce em dois diferentes desenhos de implantes / Histological and histomorphometric analysis of perimplant osseous repair in dogs submitted to endosseous implant installation with early load model in two different implant design

Several treatment types using prosthesis over implants have been reported, being the singles immediate loading therapy with more controversy. The meaning of the present study is established the characteristics of bone repair in dental implant submitted to immediate loading. It wa...

Analise fotoelastica e extensometrica das tensoes induzidas por estruturas de protese sobre implantes fabricadas pelas tecnicas monobloco, soldagem de borda e metodo CAD/CAM / Photoelastic and strain gauge analysis of tensions induced over implant superstructures manufactured through one-pierce technique., bolder soldering and CAD/CAM method, border soldering and one-piece technique

The lack of passivity of the implant supported prosthesis may lead to mechanical and biological disorders over the implants. By the photoelastic and strain gauge analysis, the purpose of this research was to evaluate the stress over the implants after tightening the prosthesis su...

Análise fotoelástica da distribuição das tensões ocorridas no tecido ósseo, ao redor de cinco diferentes desenhos de implante, quando submetidos ao carregamento axial / Photoelastic analysis of stress distributions occurring around the bone tissue of five different designs of implants when subjected to axial loading

The design of the implant is a highly relevant factor in the distribution of stresses generated in the peri-implant tissues. The proposition of this study was to evaluate the stress distribution of five different designs of implants, when subjected to axial loads uniformly distri...

Dealing with dental implant failures

An implant-supported restoration offers a predictable treatment for tooth replacement. Reported success rates for dental implants are high. Nevertheless, failures that mandate immediate implant removal do occur. The consequences of implant removal jeopardize the clinician's effor...

Experimental study on penetration of dental implants into the maxillary sinus in different depths

The exposing of dental implant into the maxillary sinus combined with membrane perforation might increase risks of implant failure and sinus complications. Objective: The purpose of this study was to investigate the effects of the dental implant penetration into the maxillary s...
