In vivo Evaluation of Zirconia Abutments in Implant supported Restorations in Partially Edentulous Patients
Dental implants have been a universally accepted option for prosthetic rehabilitation of partially edentulous patients. Titanium implants abutments exhibit a dull grayish hue and give an unnatural appearance. Abutments based on zirconia are one of the alternatives to titanium abutments. To date, few comparative studies have reported on esthetic and biological outcomes of implant-supported resto...
متن کاملImplant adaptation of stock abutments versus CAD/CAM abutments: a radiographic and Scanning Electron Microscopy study.
INTRODUCTION The study evaluated a null-hypothesis of no differences of fit between stock abutments and CAD/CAM titanium, gold sputtered and zirconia abutments when examined for radiographic adaptation and Scanning Electron Microcopy (SEM) at their inner aspect. The agreement between microscopic and radiographic fit was also assessed. METHODS Implants (Osseospeed, Astra Tech, Mölndal, Sweden)...
متن کاملbiomechanical effects of platform switching in two different implant systems: a three-dimensional finite element analysis.
the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...
متن کاملPeri-implant bone level around implants with platform-switched abutments.
PURPOSE The purpose of this clinical trial was to evaluate whether the crestal bone height around dental implants could be influenced by the use of a platform-switching protocol. MATERIALS AND METHODS All implants placed in the year 2006 in healed bone without any need for ridge augmentation were included in this study. The following groups were created: (1) wide-diameter implants were placed...
