The periodontal-restorative interface: enhancement through magnification.

One critical factor associated with aesthetics, periodontal health, and the longevity of restorations is the precision of the margins at the periodontal-restorative interface. Improper margins can cause overhangs and overcontouring that may ultimately result in caries, periodontal inflammation and breakdown, and compromised aesthetics. In order to prevent pathology at the restorative-tooth interface, each phase of the aesthetic treatment must be performed with precision and care. This article presents the utilization of an operating microscope to improve the marginal adaptation of all-porcelain restorations.
