title: Altered passive eruption.
abstract: Biologic contributions to the smile play an important role in esthetics. The impact of the gingival complex on the esthetic qualities of a smile are significant, and both patients and dentists are developing a greater appreciation for the impact of gingiva on the beauty of a smile. Historically, the focus of periodontal therapy has been on managing patients with longer-appearing teeth secondary to attachment loss through pathology or as a result of periodontal surgery. Nevertheless, early diagnosis and treatment, as well as modern techniques and materials, have helped periodontology evolve to a point where such problems occur less frequently.
