Bottom Line: Many different causes can be responsible for short clinical crown.In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length.According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment.

ABSTRACT
The aim of this case report was to describe the surgical sequence of crown lengthening to apically reposition the dentogingival complex, in addition to an esthetic restorative procedure. Many different causes can be responsible for short clinical crown. In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length. According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment.

Mentions: Initially, an impression of the maxilla was obtained to realize the diagnosis wax-up (Figure 3), and then a surgical guide in silicone, with the edge tangent to the cervical region of wax-up, was confectioned (Figures 4 and 5). The guide was inserted in mouth and the new gingival margin was registered with a scalpel (Figure 6). Thus, a full-thickness mucoperiosteal flap was elevated (Figure 7) and the gingival collar extracted with a Gracey curette. For the osteotomy, measurement of the distance between the guide edge and the cervical bone was recorded (Figure 8). This distance should be about 3 mm, for the biologic width maintenance and installation of prosthesis. The creation of a precise biologic width requires, in addition, a precise osseous contouring, which was performed using manual instruments (surgical chisels) and carbide/diamond burs with adequate irrigation, for preventing bone necrosis (Figures 9–11); then, the flaps were sutured (Figure 12). After 6-month healing (Figure 13), the provisional facets were installed for aesthetic test and posterior definitive prostheses were delivered (Figure 14).
