Abrasive Technology in Ceramic Restorative Dentistry

The application of abrasive technology in dentistry dates from 7000–9000 years. How does this ancient technology affect our modern society where the elderly population needs extensive dental care and ageing well and ageing productively is our first priority? Many patients prefer tooth-colored, all ceramics restorations fabricated by dental CAD/CAM systems for reasons of esthetics, biocompatibility and high efficiency. In spite of the advantages of all-ceramic restorations, ceramic prostheses have not always performed as predicted or desired. Catastrophic fracture has been the most frequently reported reason for failure of all-ceramic restorations. This paper gives a brief review on abrasive technology in ceramic restorative dentistry to highlight problems to be solved by our abrasive technology community.
