Similar to natural teeth, implants are liable to destruction of support structures. This process of destruction is often the result of opportunistic infections by bacteria that colonizes restorations on the implants and adjacent theeth. A. actinomycetemcomitans is often isolated ...

The aim of this study was to develop a dental implant for use in dogs with similar format to the biradicular teeth of these animals and surgical technique for its implantation, with features that allow the osseointegration. The implant is composed of three parts, two conic thread...

Osseointegrated implants and prostheses installed on them have been used in substitution of lost teeth. The index of success in Implantodonty has increased with the discovery of the osseointegration by Professor Branemark, and since then, some systems and implants brands have bee...

The success of the treatment through the placement of osseointegrated implants will require appropriate cavities so it happen an ideal osseointegration. The equipment that was needed to make these cavities must be the most accurate promoting holes with uniform wall and without ne...

The purpose of the present study was the histological and biomechanical comparison of two types of surface in commercially pUfe titanium cylinders implants. For this study the titanium implants with 6 mm oflength and 3 regular V Shaped furrows, were inserted in the tíbial metaphy...

The aim of this study was to evaluate through photoelastic analysis, the distribution of generated stress around implants and adjacent bone tissue, using differents implant-retained overdentures designs. Over an edentulous human mandible, achieve from a human model, 2 or 4 micro-...

A Prótese Buco Maxilo Facial é a especialidade da Odontologia responsável pela confecção de próteses intra e extra-bucais, indicadas quando regiões maxilofaciais foram perdidas. Implantes craniofaciais podem servir como ancoragem para próteses faciais, inclusive as óculo-palpebra...

Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the ...

OBJECTIVES: The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free...

It has been shown that the development of peri-implant mucositis is associated with biofilm accumulation. It is believed that the therapeutic approaches used in periodontal disease may have a positive effect in the cases of peri-implant disease. The aim of this study was to evalu...

Less rigid oclusal materials such as acrylic resins are often used in prosthesis over implants because they are supposed to diminish the loads transferred to the bone; however there is no scientific evidence to support this theory. The objective of this work was to compare by pho...

The clinical success of dental implants has as important factor the way the mechanical stress is transferred from the implant the surrounding bone tissue. This transference and its magnitude may be related to the material of the screwed the prosthesis to the implants, risking the...

The present study aimed at obtaining comparative elements among the guided systems of fixed complete denture with 4 osseointegrated implants with immediate loading, considering the importance of understanding the implant project as a process where biomaterials and biomechanics ar...

Abstract Introduction The bone-implant interface has been studied extensively, but only few papers focused on the nutritional aspects that may affect bone quality, especially salt intake. Objective To study the osseointegration of implants in salt-loaded rats with low mineral...

The osseointegrated titanium implants are reliable and safe alternatives to treatments for long periods of time. For surface modification, thermal aspersion of TiO2 was used. The samples with and without TiO2 were treated with NaOH and SBF in order to obtain a layer of HA. Charac...

A utilização de implantes osseointegráveis como substituto dentário tornou-se amplamente adotada desde a instalação e relato de sucesso dos primeiros implantes em seres humanos. A cirurgia para instalação de implantes osseointegráveis pode ser realizada em dois estágios, aguardan...

Osseointegrated implants have now been proved to be feasible. However, several factors still remain to be explained, particularly because of the large number of manufacturers and models. Although incidence is low, implant fractures are a clinical reality, and therefore researches...
