CAD/CAM-Technique in Restorative Dentistry / CEREC - Pt. 1: Choice of Materials, Treatment Planning, Occlusion Control

CAD/CAM in Restorative Dentistry is introduced in this series by Dr. Alessandro Devigus, Switzerland. In part 1 he presents the diagnostic procedure, his choice of the necessary materials and the general restorative treatment planning with the CAD/CAM-technology by taking the example of a second left molar in the lower jaw. An insufficient composite filling needs to be replaced by a CEREC-inlay.

The most important step previous to preparation and restorative rehabilitation is to analyze the current occlusal contact situation. For analysing the maximum intercuspal position contact points of the static relationship of the maxillary and mandibular teeth are recorded with contact paper documentating strength, extent and location of the occlusal areas. Due to that the jaw relationship during mastication in dynamic occlusion is visualized. Functional movements can be seen in excursion with contact paper.

The functional occlusion has to be reproduced in the ceramic restoration to obtain repeatable static and dynamic information for occlusal harmony without interfering or deflective contacts avoiding dysfunction and fractures. See more about Computer added design (CAD) and Computer added manufacturing (CAM) with the CEREC-system in part 2 to 4 on Dental Online College.
