Surgical Crown Lengthening: A 12-Month Clinical Wound Healing Study
Roberto Pontoriero* and Gianfranco Carnevale†
Background: Surgical crownlengthening has been proposed as a means of facilitating restorative procedures and preventing periodontal injuries in teeth with structurally inadequate clinical crowns or exposing toothstructure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. The few clinical studies in the current literature on postsurgicalsoft tissue modifications after crown lengthening procedures report conflicting results. The present study was designed to assess the alterations of the marginal periodontal tissues asan immediate outcome of surgical crown lengthening and over a 12-month healing period. Methods: The patient sample included 30 patients (84 teeth) who presented with variousconditions hampering proper restorative measures in one or more teeth and, therefore, requiring surgical exposure of tooth substance. After initial supportive therapy, the patients wererecalled for a baseline examination, and the following parameters were evaluated at interproximal and buccal/lingual sites of each experimental tooth: plaque index, gingival index,position of the gingival margin, probing depth, and attachment level. After baseline examination, the patients underwent apically positioned flap surgery with osseous and connective tissueattachment resection. During surgery, the amount of resection and the achieved lengthening of the clinical crown were evaluated. The patients were enrolled in a maintenance programincluding professional tooth cleaning every 2 to 4 weeks. The patients were reexamined 1, 3, 6, 9, and 12 months postoperatively.
