FULL GOLD CROWN

The preparation for a Full Gold Crown involves circumferential (around the tooth) and occlusal (surface of tooth were we bite) reduction of between 0.5 and 1.0 millimeter. This reduction is done to create space for sufficient metal to ensure adequate strength of the crown. The shape, position and contacts of a tooth are very important in the success of a crown. For gingival health, the correct shape of interproximal (space in between teeth) gingival areas are most important. Gold would be preferred for the restoration of occlusal surfaces in the presence of a tooth grinding habit, as gold is a more favorable material for the occlusal surface as its wear characteristics are more in harmony with the enamel (outer layer of tooth) of the opposing tooth.

Tooth preparation for a metal-Ceramic Crown

Porcelain fused-to-metal restorations can achieve the most natural and aesthetic results when the preparation allows sufficient space for both the internal metal substructure and the external build-up of multiple, porcelain layers. In the preparation for a metal-ceramic crown, it is necessary to create space for 0.5 mm of metal plus 1.5 mm of porcelain to ensure adequate strength and optimum esthetics of the ceramic material.
