Minimally Invasive Surgery for Clinical Crown Lengthening Using Piezoelectric Ultrasound

Figure 3

Surgical procedure. (a) Initial incision with the aid of a mockup that was used as a guide for gingival tissue removal. (b) During the probing procedure, it was verified that the distance from the gingival margin to the top of the bone crest was 1 mm, which meant that the osteotomy procedure was necessary. (c) Osteotomy was performed with piezoelectric ultrasound without flap elevation and without interference in the interdental papillae. (d) The procedure removed 1 mm of bone tissue to restore the biological space, taking into account the thin gingival phenotype presented in the patient. (e) Immediate postoperative situation where it is possible to perceive a minimally traumatic clinical condition. (f) The good postoperative condition observed 6 months after the surgical procedure: the periodontal tissue was completely healed.
