Today’s dentist does not just repair teeth to make them better for chewing. Increasingly, his or her work involves esthetics. With patients demanding more attractive teeth, dentists now must become more familiar with the formerly independent disciplines of orthodontics, periodontics, restorative dentistry, and maxillofacial surgery. This article provides a systematic method of evaluating dentofacial esthetics in a logical, interdisciplinary manner. In today’s interdisciplinary dental world, treatment planning must begin with well-defined esthetic objectives. By beginning with esthetics, and taking into consideration the impact on function, structure, and biology, the clinician will be able to use the various disciplines in dentistry to deliver the highest level of dental care to each patient.
