EVALUATION OF ALVEOLAR OSTEOTOMY FOR CORRECTION OF VERTICAL BONE RESORPTION IN ANTERIOR MANDIBULAR RIDGE USING A MIXTURE OF TWO GRAFTED MATERIALS

Abstract

INTRODUCTION: Extensive loss of alveolar bone and teeth in the anterior mandible presents a complex problem for reconstruction. Alveolar osteotomy technique with the use of mixture of hydroxy apatite and beta-tricalcium phosphate together with injectable PRF is one of the reliable methods to restore vertical ridge deficiencies. OBJECTIVES: : Evaluate vertical ridge augmentation using sandwich osteotomy technique in anterior atrophic mandible and the use of hydroxy apatite, beta-tri-calcium phosphate mixed with injectable PRF as a grafting material. MATERIALS AND METHODS: This study was conducted clinically on 8 patients indicated for vertical ridge augmentation by sandwich technique osteotomy and fixation of the osteomatized segment by micro-plates and screws, and the placement of Ha- BTCP mixed with I-PRF as interpositional graft material. Patients were evaluated clinically and radiographically by using panoramic radiograph and cone beam computed tomography (CBCT). RESULTS: In this study no severe pain was recorded postoperatively. No signs of inflammation or swelling were observed in almost all of the patients along the follow up period. Vertical bone height gain of the residual ridge was satisfactory and prepared the ridge to receive final prosthesis successfully. CONCLUSIONS Sandwich osteotomy technique with Ha- BTCP mixed with I-prf is a reliable method to restore vertical ridge deficiencies in anterior mandible.
