Abstract:
The influence of angled abutments on stress of peri-implant bone is a controversial issue. It is widely accepted that the use of angled abutments will increase adverse stress distributions on implants and surrounding bones. However, comparisons of clinical success rates of implants restored with angled and straight abutments indicate no significant differences. This review summarized the clinical application and biomechanical research associated with angled abutments. The use of angled abutments did not detrimentally affect the retention of dental implants, and tt was possible that the magnitude of stress within peri-implant bone increased or decreased under different conditions. Therefore, further researches should be conducted to confirm that favorable peri-implant stress levels may be induced if suitable angulation of abutments is selected.
