Resistance to dislodgement of zirconia copings cemented onto titanium abutments of different heights.
STATEMENT OF PROBLEM For patients with limited interocclusal space, standard height implant abutments may not be usable. Shorter abutments may be desirable. PURPOSE The purpose of this study was to determine the effect of the height of titanium abutments on the tensile strength required to dislodge zirconia copings. MATERIAL AND METHODS Two experimental groups of abutments were prepared: (1...
متن کاملAssessment and comparison of retention of zirconia copings luted with different cements onto zirconia and titanium abutments: An in vitro study
AIM The purpose of this in vitro study was to assess and compare the retention of zirconia copings luted with different luting agents onto zirconia and titanium abutments. MATERIALS AND METHODS Titanium and zirconia abutments were torqued at 35 N/cm onto implant analogs. The samples were divided into two groups: Group A consisted of four titanium abutments and 32 zirconia copings and Group B ...
متن کاملA Comparison of Zirconia and Titanium Abutments for Microleakage.
BACKGROUND Microleakage through the interface has been documented in implant systems with titanium (Ti) abutments. There is a current increase in the use of zirconia (Zi) abutments especially in esthetic zone in where higher risk of visible metal color through the peri-implant tissues exists. PURPOSE The aim of the present in vitro study is to evaluate the leakage at the implant fixture-abutm...
متن کاملFracture resistance of implant- supported monolithic crowns cemented to zirconia hybrid-abutments: zirconia-based crowns vs. lithium disilicate crowns
PURPOSE The aim of this in vitro study was to investigate the fracture resistance under chewing simulation of implant-supported posterior restorations (crowns cemented to hybrid-abutments) made of different all-ceramic materials. MATERIALS AND METHODS Monolithic zirconia (MZr) and monolithic lithium disilicate (MLD) crowns for mandibular first molar were fabricated using computer-aided design...
متن کاملThe effect of resin cements and primer on retentive force of zirconia copings bonded to zirconia abutments with insufficient retention
PURPOSE The purpose of this study was to investigate the effect of resin cements and primer on the retentive force of zirconia copings bonded to zirconia abutments with insufficient retention. MATERIALS AND METHODS Zirconia blocks (Lava, 3M ESPE, St. Paul, MN, USA) were obtained and forty sets of zirconia abutments and copings were fabricated using CAD/CAM technology. They were grouped into 4...
