Extensive Amalgam Restorations

Abstract

The restoration of large cavities on posterior teeth with amalgam is a good option to recover the shape and function of the affected tooth. Due to the restoration size, retention is the main concern, and different techniques are presented in this chapter about how to provide it in a natural and artificial way. The procedure of cuspal-coverage is described, which can avoid large fractures of the weakened cusps. Other ways to improve the resistance of the remaining tooth structure and restoration are also presented. Due to the low cost, it can be an alternative to indirect restorations, using just one clinical session. To increase its durability, practitioners must understand and correctly apply the principles associated to the preparation and restorative technique.
