Full-Zirconia Single Molar Implant-Supported Restorations With Angulated Screw Channel Abutments: 5-Year Results of a Prospective Case Series Study.

ABSTRACT:

Introduction

Full-zirconia (ZrO₂) restorations were introduced to address the most common complications in implant-supported restorations in the posterior region: fractures of the veneering. The aim of this prospective case series study was to evaluate full-ZrO₂ implant-supported restorations with angulated screw channel abutments (ASCs) in the molar region of the maxilla and mandible and their effect on hard and soft peri-implant tissues, and patient-related outcome measures (PROMs), during a 5-year follow-up period.

Material and methods

Patients with a single missing molar in the maxilla or mandible with sufficient bone volume and an implant site free of infection were included. Thirty consecutive patients received a parallel-walled implant with conic
