Placement of Free Gingival Grafts on Denuded Alveolar Bone—Part I: Clinical Evaluations

Abstract

Fourteen patients were examined and determined to lack an adequate zone of attached gingiva in the mandibular incisor region. Each patient was treated on the left side of the mandible by placement of a free gingival graft on denuded bone and 12 of the 14 patients received a free gingival graft on retained periosteum in the right mandibular anterior region. Two patients were treated on the right side by either bone denudation or periosteal bed preparation without graft placement to permit histological evaluation of wound healing under these circumstances. Grafts were retained for time intervals from 1 week to 24 weeks. All patients were evaluated clinically for graft "take", graft healing, graft shrinkage, and graft mobility.
