The Influence of Design on Stress Concentration Reduction in Dental Implant Systems Using the Finite Element Method

Crystals, 2023
Dental implant fracture is closely connected to the stress buildup surrounding the implant system during static loading. In areas where the cross-section of the implant rapidly changes or where the geometry of the implant system has discontinuities ...

INFLUENCE OF DIFFERENT IMPLANT ABUTMENT CONNECTION DESIGNS ON ABUTMENT SCREW LOOSENING IN DENTAL IMPLANT SYSTEMS – A SYSTEMATIC REVIEW.

International Journal of Medical and Biomedical Studies, 2019
Background: Dental implants have provided an alternative method of prosthetic rehabilitation with high long-term success rates. However, mechanical or biological complications may occur with implants amongst which loosening of the screw is very common. Loosening of the screw might cause misfit of implant?abutment interface and may occur due to preload ...

The effect of dynamic loading on bacterial microleakage of the dental implant fixture-abutment interface: An in vitro study

The Journal of Indian Prosthodontic Society, 2021
Aim: Bacterial micro leakage at implant-abutment interface under functional loading is an important factor, may lead to crestal bone loss and affect the long term success of dental implants.

Osseointegration of zirconia implants compared with titanium : an in vivo study [PDF]

, 2008
Background Titanium and titanium alloys are widely used for fabrication of dental implants. Since the material composition and the surface topography of a biomaterial play a fundamental role in osseointegration, various chemical and physical surface ...
