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.
