Zirconia implant abutments: a review.
OBJECTIVES An increasing aesthetic demand within developed populations conducted to the fabrication of metal-free restorations and to a wide use of ceramic materials, due to its excellent characteristics of biocompatibility and aesthetics. With the incessant increase of commercial labels involved in this technological advance, a review is imposed on ceramic abutments, specifically on zirconia. ...
متن کاملZirconia implant abutments: A review
PURPOSE: The aim of this study was to evaluate in vitro the microgap between different zirconia abutments and their titanium implants. MATERIALS AND METHODS: Four systems were evaluated: Procera zirconia (Nobel Biocare) (Nb), Cercon Balance Anterior (Dentsply Friadent) (Ba), ZirDesign (Astratech) (Zd), and Straumann Cares ceramic (Straumann) (Ca). Five assemblies were assessed for each system. ...
متن کاملZirconia implant abutments: A review
OBJECTIVE: The purpose of this study was to determine the fracture strength of zirconium implant abutments and the torque required to unfasten the retaining screw before and after applying cyclic loading to the implant-abutment assembly. The dynamic behavior and stress distribution pattern of zirconium abutments were also evaluated. METHODS AND MATERIALS: Static and cyclic loading of 7 XiVE imp...
متن کاملMechanical behavior of provisional implant prosthetic abutments
INTRODUCTION Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization. OBJECTIVES In vitro testing of strength and deformation of implant ...
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)...
