Evaluation of the marginal fit at implant-abutment interface by optical coherence tomography.
Vertical misfit of implant-abutment interface can affect the success of implant treatment; however, currently available modalities have limitations to detect these gaps. This study aimed to evaluate implant-abutment gaps in vitro using optical coherence tomography (OCT). Vertical misfit gaps sized 50, 100, 150, or 200 μm were created between external hexagonal implants and titanium abutments (N...
متن کاملMarginal Vertical Fit along the Implant-Abutment Interface: A Microscope Qualitative Analysis
The aim of this study was to qualitatively evaluate the marginal vertical fit along two different implant-abutment interfaces: (1) a standard abutment on an implant and (2) a computer-aided-design/computer-aided-machine (CAD/CAM) customized screw-retained crown on an implant. Four groups were compared: three customized screw-retained crowns with three different "tolerance" values (CAD-CAM 0, CA...
متن کاملAnalysis of implant/abutment marginal fitting
The success rate of osseointegrated implants is reported to be above 90%. Despite of the knowledge of the mechanisms of osseointegration, some faults still occur at implants systems. Recent researches assign those faults mainly to patient’s prosthetic rehabilitation. The misfit at abutment-implant interface and the missing of a passive adaptation between the prosthesis and the abutment can lead...
متن کاملComparative study of torque resistance and microgaps between a combined Octatorx-cone connection and an internal hexagon implant-abutment connection.
STATEMENT OF PROBLEM Although the implant-abutment connection may prevent crestal bone loss around dental implants, its failure often leads to treatment failure. Microgap and micromovement of the implant-abutment connection could be causes of bone resorption around dental implant neck. PURPOSE The purpose of this study was to compare torque resistance and microgaps between a new cone and inde...
متن کاملMarginal fit at cylinder-abutment interface before and after overcasting procedure.
The aim of this study was to measure marginal fit at cylinder-abutment interface, before and after overcasting procedure. A hexagonal implant was fixed to a stainless steel base and a Estheticone-like abutment used during all the experiment. Before casting procedure, gold (Group I) and Ni-Cr-Be (Group II) premachined cylinders were tightened to the abutment with gold and titanium screws (in bot...
