Abstract
The replacements of missing teeth with implant supported single crowns and fixed dental prostheses have become a standard treatment modality. Metal abutments made out of titanium have proven to be durable, however, it was reported to cause a grayish discoloration of the peri-implanted mucosa. For this reason, all-ceramic abutments made out of high-strength ceramics have been developed. Today, zirconia abutments with various implant-abutment connection geometries exist for different implant types. Significantly higher values were achieved for CAD/CAM zirconia abutments with internal connections via a secondary titanium insert (two-piece) than for the ones with external connections or one-piece abutment. The use of a secondary titanium insert might have a beneficial influence on the stability of zirconia abutments and appears to be clinically useful for anterior single-tooth replacement. This case report provides a clinical case of two-piece zirconia abutment using the titanium core. It may be effective as compared to that of other conventional treatments in esthetics. And further controlled clinical studies are needed to evaluate the effects and complications.
