Evaluation of gold-machined UCLA-type abutments and CAD/CAM titanium abutments with hexagonal external connection and with internal connection.
PURPOSE The purpose of this study was to assess the precision at the implant interface of gold-machined UCLA-type abutments and computer-assisted design and manufacture (CAD/CAM) titanium abutments with both external-hexagonal connection and internal-hexagonal connection. MATERIALS AND METHODS Fifteen gold-machined UCLA-type abutments with external-hexagonal connection, 15 gold-machined UCLA-...
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 کاملBending moments and types of failure of zirconia and titanium abutments with internal implant-abutment connections: a laboratory study.
PURPOSE The aim of this study was to examine the bending moments and fracture patterns of different zirconia abutments with internal implant-abutment connections after static loading and to compare their bending moments to those of internally connected titanium abutments. MATERIALS AND METHODS Three types of customized zirconia abutments (Straumann CARES abutments/Straumann BL implants [T1], ...
متن کاملComparison of fit accuracy and torque maintenance of zirconia and titanium abutments for internal tri-channel and external-hex implant connections
PURPOSE This in vitro study aimed to evaluate the effect of implant connection design (external vs. internal) on the fit discrepancy and torque loss of zirconia and titanium abutments. MATERIALS AND METHODS Two regular platform dental implants, one with external connection (Brånemark, Nobel Biocare AB) and the other with internal connection (Noble Replace, Nobel Biocare AB), were selected. Se...
متن کاملComparison of internal fit between implant abutments and cast metal crowns vs laser-sintered crowns.
AIM A common problem related to cemented single crowns is the internal misfit, which may cause inadequate retention, especially when seated on the implant abutment. The aim of this study was to compare the internal fit of Co-Cr crowns using a traditional lost-wax casting technique from laser-sintered Co-Cr alloy crowns. MATERIALS AND METHODS Twelve metallic crowns per each technique were fabr...
