Alumina reinforced zirconia implants: Effects of cyclic loading and abutment modification on fracture resistance

摘要

Objective. The aim of the study was to evaluate the thermomechanical behavior of alumina-toughened zirconia (ATZ) oral implants in the artificial mouth and the fracture resistance (fracture load and bending moment) in a subsequent static fracture load test. The effects of abutment modification and different cyclic loadings were evaluated.
