Abstract

Recent reports documented a tissue engineering approach to simultaneously augment hard and soft tissues for implant site preparation in the esthetic zone. A 31−year−old woman presented with an oblique root fracture of the maxillary central incisor, which could not be saved. The treatment plan was to extract the tooth and replace it with an implant. At the time of tooth extraction, guided bone regeneration (GBR) with −TCP granules and a resorbable membrane and a subepithelial connective tissue graft were simultaneously planned for the buccal bone defect. Nine months after extraction, an implant was placed inthe central incisor position, but the bone at the buccal aspect of the implant was thin and v−shaped. Therefore, the buccal bone defect was simultaneously augmented with GBR. Gingival recession occurred at the buccal aspect of the implant, one month after the healing abutment and provisional restoration were placed. Periodontal plastic surgery was performed to correct the marginal mucosal recession at the implant site. A recall visit forty months after implant placement revealed that the implant was maintained well and the soft tissues were stable.
