Polishing Mechanism And Its Effect On The Mechanical Properties Of Ceramic Restorations - A Review Of The Literature

Abstract

Polishing of dental ceramics has become an increasingly important procedure in restorative dentistry as allceramic restorations, which require post-cementation occlusal adjustment, are gaining in popularity. There are numerous studies in both dental and ceramic literature on polishing of dental ceramics and the effects of polishing on their mechanical properties. However, lack of standardization in polishing parameters, precludes comparison among these studies. A clear understanding is lacking of the relative roles and interdependence of handpiece speed, abrasive characteristic, and polishing load. This paper will discuss the mechanism of polishing and review the literature on polishing and its effect on the mechanical properties of ceramic restorations.
