Fracture loads and failure modes of customized and non-customized zirconia abutments

The use of zirconia abutments for dental implants in oral rehabilitation is increasing because of their superior biocompatibility and aesthetics. When a metallic abutment is used and the gingival tissue is thin [1], thus permitting light transmission [2,3], the gingival tissue would appear dark gray due to the underlying metallic abutment. This can be avoided by using ceramic abutments, which will help to achieve gingival appearance similar to that with natural teeth, especially in the anterior region [4].
