Sequential tooth preparation for aesthetic porcelain full-coverage crown restorations.

The fabrication and delivery of functional, biocompatible restorations with a natural appearance have become the definitive goals of restorative dentistry. Although contemporary ceramic materials allow light to be manipulated in restorations to replicate the natural dentition, this objective can be difficult to achieve when tooth preparation is not performed properly. This article presents a sequential approach that can be used to render the proper shape and margin design critical to the fabrication of full-coverage crown restorations that are indistinguishable from the adjacent natural teeth.
