Effect of central screw taper angles on the loosening performance and fatigue characteristics of dental implants.

Biomechanical performance plays an important role in the long-term service of dental implants. Loosening and fatigue damage of the central screw are the most common problems. This research investigated the effect of the central screw taper angle on the loosening performance and fatigue characteristics of dental implants.

Effect of Loading Angles and Implant Lengths on the Static and Fatigue Fractures of Dental Implants.

Mechanical properties play a key role in the failure of dental implants. Dental implants require fatigue life testing before clinical application, but this process takes a lot of time. This study investigated the effect of various loading angles and implant lengths on the static fracture and fatigue life of dental implants.
