Surgical lengthening of the clinical crown: a periodontal concept for reconstructive dentistry
Huynh-Ba, Guy / Brägger, Urs / Lang, Niklaus Peter
This review presents the various techniques, the indications and contraindications for surgical lengthening of the clinical crown. Based on the concept of biologic width of the dento-gingival complex, the aim of surgical modifications in this region is to create a distance of approximately 3 mm between the foreseeable marginal area of a reconstruction and the crest of the alveolar bone. Studies on wound healing suggest that stability of the soft tissues following such surgical procedures is obtained after a healing period of 6 months. In order to obtain optimal aesthetic treatment outcomes of restorations, the duration of the healing period should be respected.
