Geometric considerations in anterior dental aesthetics: restorative principles.

While aesthetics is traditionally regarded as an artistic concept, quantifiable scientific principles are used in its development. Dental aesthetics are governed by mathematical parameters that, when applied by the clinician and laboratory technician, can achieve restorations with a unique aesthetic appearance. These geometric laws should not be viewed as immutable, but as useful guidelines for the fabrication sequence. This article demonstrates a series of geometric principles for the anterior maxillary dentition that can be utilized in the development of aesthetic restorations.
