Guidelines for the Preparation of CAD/CAM Ceramic Inlays and Partial Crowns
Ahlers, M. Oliver / Mörig, Gernot / Blunck, Uwe / Hajtó, Jan / Pröbstere, Lothar / Frankenberger, Roland
Ceramic inlays and partial crowns have become scientifically recognized posterior restorations. Their clinical effectiveness depends on the development of durable dental ceramics and luting materials as well as an effective bonding system. Therefore, these factors were in the focus of interest in the past. In contrast, only little attention was given to preparation techniques. However, current studies show that special preparation rules should be followed to ensure best fitting CAD/CAM ceramic restorations and long-lasting clinical success.This paper describes preparation requirements by means of detailed three-dimensional schematic drawings and then deduces the clinical procedure for the preparation of ceramic inlays and partial crowns with standardized preparation instruments.

Keywords: preparation technique, preparation design, preparation instruments, depth marking, ceramic inlays, ceramic partial crowns, production of CAD/CAM restorations, adhesive bonding, risk of fracture, cavity angle
