Three-Dimensional Finite Element Analysis of Vertical and Angular Misfit in Implant-Supported Fixed Prostheses
(Quintessence Publishing Co Inc, 2011-07-01)
Purpose: Three-dimensional finite element analysis was used to evaluate the effect of vertical and angular misfit in three-piece implant-supported screw-retained fixed prostheses on the biomechanical response in the ...
A comparison of profilometer and AutoCAD software techniques in evaluation of implant angulation in vitro
(Quintessence Publishing Co Inc, 2008-07-01)
Purpose: The aim of this study was to compare 2 different methods of assessment of implants at different inclinations (90 degrees and 65 degrees)-with a profilometer and AutoCAD software. Materials and Methods: Impressions ...
Evaluation of transfer impressions for osseointegrated implants at various angulations
(2004-12-01)
The accuracy of impressions that transfer the relationship of the implant to the metal framework of the prosthesis continues to be a problem. This study was designed to evaluate the accuracy of the transfer process under ...
Effect of Metal-Ceramic or All-Ceramic Superstructure Materials on Stress Distribution in a Single Implant-Supported Prosthesis: Three-Dimensional Finite Element Analysis
(Quintessence Publishing Co Inc, 2011-11-01)
Purpose: This three-dimensional finite element analysis study evaluated the effect of different material combinations on stress distribution within metal-ceramic and all-ceramic single implant-supported prostheses. Materials ...
Genotoxicity of corrosion eluates obtained from endosseous implants
(Lippincott Williams & Wilkins, 2007-03-01)
Purpose: Commercially pure titanium alloys are currently used as metallic biomaterials in implantology. Corrosion phenomena appear to play a decisive role in metallic implant long-term behavior. Thus, the goal of this study ...
Evaluation of Torque Maintenance of Abutment and Cylinder Screws With Morse Taper Implants
(Lippincott Williams & Wilkins, 2012-11-01)
The screw loosening of implant-supported prostheses is a common mechanical failure and is related to several factors as insertion torque and preload. The aim of this study was to evaluate the torque maintenance of retention ...
Maxillary and mandibular width changes studied using metallic implants.
(2000-01-01)
The purpose of this implant study was to evaluate the transverse stability of the basal maxillary and mandibular structures. The sample included 25 subjects between 12 and 18 years of age who were followed for approximately ...
Effect of axial loads on implant-supported partial fixed prostheses by strain gauge analysis
(2011-11-01)
Objectives: The present study used strain gauge analysis to perform an in vitro evaluation of the effect of axial loading on 3 elements of implant-supported partial fixed prostheses, varying the type of prosthetic cylinder ...
