INTRODUCTION
An important synergy exists between periodontics and restorative dentistry. The gingival architecture plays a critical role in the development of proper tooth size, shape, and tooth-to-tooth proportion. An accurate understanding of the hard- and soft-tissue anatomy, as well as how they relate to restorative treatments, is vital in creating anterior dental aesthetics. A multidisciplinary approach is often required to achieve ideal results.
The functional and aesthetic requirements of restorative dentistry direct the periodontal component of treatment. Optimal aesthetic restorative results can be accomplished by performing delicate periodontal procedures. Clinical crown lengthening surgery can shape a hard-tissue foundation that will support a natural appearance in the soft-tissue architecture. In addition, clinical crown lengthening will provide sufficient amounts of tooth structure for ideal tooth preparation and restoration.This is very important, due to the detrimental effects of improper placement of restorative margins and violation of biologic width.7
