Surgical template for crown lengthening: A clinical report

Surgical lengthening of clinical crowns represents one of the most commonly used procedures in contemporary periodontics. Indications include: (1) lack of sufficient length of a clinical crown to ensure a tooth preparation for fixed prosthodontics with retentive and resistance form; (2) preexisting dental caries or restorations in the vicinity of the free gingival margins that prevent preparation of finish lines for restorative margins coronal to the biologic width; (3) the need to develop a ferrule for pulpless teeth restored with posts1,2; and (4) unesthetic gingival architecture as a result of altered passive eruption.
