Vertical Bone Augmentation Using a Polytetrafluoroethylene Nonporous Barrier for Osseointegrated Implants Partially Inserted in Tibiae of Rabbits
(Lippincott Williams & Wilkins, 2009-04-01)
Purpose: The aim of this study was to evaluate the possibility of obtaining guided bone regeneration using a poly-tetrafluoroethylene (PTFE) nonporous barrier for 2 endosseous implants, partially inserted in tibiae of ...
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 ...
Use of carbon dioxide (CO2) laser radiation in exposure of implants (stage II): A metallography evaluation in dogs
(Laser Inst Amer, 2002-11-01)
In this study we analyzed possible damages that vaporization from laser radiation could cause to implant material. Fifteen standard titanium implants, measuring 3.75 mm in diameter by 7 mm in length, were placed into the ...
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 ...
Evaluation of Stress Patterns Produced by Implant-Retained Overdentures and Implant-Retained Fixed Partial Denture
(Lippincott Williams & Wilkins, 2011-11-01)
The purposes of this study were to photoelastically measure the biomechanical behavior of 4 implants retaining different cantilevered bar mandibular overdenture designs and to compare a fixed partial denture (FPD). A ...
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 ...
Alveolar bony crest preservation at implants installed immediately after tooth extraction: An experimental study in the dog
(2013-01-01)
Aim: To evaluate the influence of deproteinized bovine bone mineral in conjunction with a collagen membrane, at implants installed into sockets in a lingual position immediately after tooth extraction, and presenting initial ...
