Overcoming and Preventing Dental Implant Complications: Abutment Fracture Case Report
Since its introduction in northern Europe in the 1960s, dental implant has been used all over the world as an option to restore teeth and periodontal tissues. In the early stage, dental implant prosthesis was used restrictively to replace removable prosthesis; currently, however, it is also used for stationary prosthesis. This treatment utilizes various methods including osseointegration after ...
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 کاملEvaluation 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 کاملSinking and fit of abutment of locking taper implant system
STATEMENT OF PROBLEM Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE In this study, Bicon® Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measure...
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...
