Preparation guidelines for full and partial coverage ceramic restorations.
Aesthetic awareness of dental patients has produced a growing demand for posterior tooth-coloured restorations. This has led to the development of posterior composite resins and, more recently, posterior all-ceramic restorations. In the last decade, modern technological advances have allowed the production of stronger ceramics and better luting techniques, which have led to the use of all-ceramic restorations in posterior sites. The preparation guidelines for posterior ceramic restorations outlined in this paper emphasize rounded internal line angles and a chamfer or rounded shoulder finish-line.
