A Noval Alveolar Bone Grafting Technique For The Insufficient Mandibular Anterior Alveolar Bone: Horse-Shoe Technique

Abstract

Objective: Introduction: The purpose of these case report is to report a new technique to provide a sufficient alveolar bone for implant surgery. In this technique,the mandibulary anterior region was aimed to be used as a donor site and the grafted site, simultaneously. Case: Two elderly patients, whose vertical bone height to the mandibular inter-mental region was sufficient but the horizontal bone thickness is insufficient, applied to our faculty clinic. During the operations, the sufficent bone did not exist even in the lower section of the mandible anterior. In these cases, instate of using burs to eliminate the height of the bone, it was decided to use these bony structures as a bone graft in the buccal side of the mandible where the implants were planned to be placed. The piezosurgery was preferred and the horse-shoe shaped block bone graft was fixed horizontally to the anterior region of the mandible with screws. In both cases, the crest split technique was performed to allow placing two implants before these operations. The postoperative periods were uneventful. The control CBCT scan showed a good new bone organization allowing for the placement of a dental implant even in failure situations in 3-4 months. Conclusion: Here we report a novel alveolar bone graftng technique;which was represented as -horse-shoe technique-.The major advantages were no donor site morbidit less risk of the complication of the failure of the bone grafting due to the autogenous bone grafts,and gain a thicker keratinized periodontal tissue in the buccal side of the implants.
