OBJECTIVE The aim of this study was to evaluate the influence of implant diameter, length and shape on a surrogate parameter of implant survival; i.e. the implant return rate in a big data analysis. MATERIALS AND METHODS A retrospective study was conducted and the factors influencing the success rates of 69,377 sold implants over a seven-year period were evaluated. The osseointegration progra...

the main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region.four three-dimensional finite element models (3d fem) were designed from a mandible containing an implant-supported bridge extending between canines, and a bilateral distal extension remo...

BACKGROUND Acceptable short-term survival rates (>90 %) of mini-implants (diameter < 3.0 mm) are only documented for mandibular overdentures. Sound data for mini-implants as strategic abutments for a better retention of partial removable dental prosthesis (PRDP) are not available. METHODS/DESIGN The purpose of this study is to test the hypothesis that immediately loaded mini-implants show mor...

This study's aim was to evaluate the stress distribution in a mandibular implant-supported prosthesis and peri-implant bone considering implant quantity, diameter and position using linear 3-D finite element analysis. Models of an anterior jaw comprised 4 groups according to implant quantity, diameter, and position: control group C, 5 regular implants; R, 3 regular implants; W, 3 wide implants;...

OBJECTIVES This preliminary investigation aimed to evaluate the potential of contaminated implants to reosseointegrate into pristine sites and, in addition, to assess the potential of osseointegration of new implants in peri-implantitis sockets in a canine model. METHODS All mandibular premolars were bilaterally extracted from two mongrel dogs. Following 12 weeks of healing, two dental implan...

To address the need for minimally invasive treatment of unresectable tumors, intratumoral polymer implants have been developed to release a variety of chemotherapeutic agents for the locoregional therapy of cancer. These implants, also termed "polymer millirods," were designed to provide optimal drug release kinetics to improve drug delivery efficiency and antitumor efficacy when treating unres...

The possibility of using osseointegrated implants for orthodontic anchorage is well known. When absolute orthodontic anchorage is needed, mini-implants can be inserted in the non-alveolar bone area (e.g. palatal process or retromolar areas of the mandible). However, what happens to these implants at the end of treatment can be a problem as neither trephine explantation nor simply leaving the su...

With the 2006 Food and Drug Administration approval of round silicone gel breast implants in the United States, there still remained a lack of versatility in implant options. The approval of Sientra's shaped cohesive implants in 2012 brought with it the innovations needed to address varying patient needs. Because access to shaped devices is still fairly recent in the United States, some surgeon...
