Abstract

This case report examines the cause of zirconia abutment fracture in implant treatments. Two patients who experienced a fracture of a maxillary incisor received a titanium base implant with zirconia custom abutments. Fractures were observed at the cervical area of the connection of the titanium base and zirconia abutment. Six causes of fracture were analyzed for each of the two cases including manufacturing defects of zirconia blocks, thin sidewall thickness of zirconia, strong internal stress, implant angulation, concentration of excessive stress according to occlusal aspect, adhesion problem of titanium base, and zirconia abutment.
