Eleven-Year Follow-Up of a Prospective Study of Zirconia Implant Abutments Supporting Single All-Ceramic Crowns in Anterior and Premolar Regions.

Background: Clinical studies on zirconia abutments report very good survival rates and biological and technical results, but few have an observation period of more than 5 years.

Purpose: The aim of this study was to assess the long-term performance of customized zirconia implant abutments supporting all-ceramic crowns.

Materials And Methods: Twenty-seven patients receiving 54 single implants were included (25 incisors, 14 canines, 15 premolars in both jaws).

Decisive progress in dental technology by Professor Peter Schärer.

Throughout his career, Professor Peter Schärer developed and helped establish some of the most significant advancements in dental technology and technique. In honor of his legacy, this article presents a number of Prof Schärer's most notable contributions to the field, such as the hotpressing technique, full waxup try-in, and advancements in zirconium oxide materials. Professor Schärer's dedication to bold and innovative ideas, as well as his philosophy of collaboration between the dentist and dental technician, are responsible for vast improvements in the field of dental technology, many of which are now recognized worldwide.

Experimental zirconia abutments for implant-supported single-tooth restorations in esthetically demanding regions: 4-year results of a prospective clinical study.

Purpose: This prospective clinical study evaluated an experimental implant abutment made of densely sintered zirconia with respect to peri-implant hard and soft tissue reaction as well as fracture resistance over time.

Materials And Methods: Twenty-seven consecutively treated patients with 54 single-tooth implants were included. Zirconia abutment ingots were individually shaped and set on the implants with gold screws.
