Abstract
Objective: This is to report the efficacy of the sandwich technique for bone augmentation in a moderate atrophic posterior mandible through clinical and histological results in two cases.
Subjects and Method: Two patients selected had moderate bone resorption in left lower edentulous area. Sandwich osteotomy using the piezosurgery was performed and the osteomized alveolar segments were elevated by 6mm in each two patients. The interpositional mineral allograft materials were inserted in the atrophic posterior mandibles. After four months healing period, bone biopsies in the grafted areas and placement of dental implants were performed. In both cases, panoramic views were taken preoperatively to measure the alveolar bone height for diagnosis, to monitor patient healing, and to evaluate bone healing and bone gain.
Results: Sufficient vertical bone height was gained by using the sandwich technique and implants were placed successfully. In radiological evaluation, there was minimal resorption of bone height after the second operation and in histomorphometric evaluation, they showed favorable new bone formation without inflammation in the grafted areas.
Conclusion: The sandwich technique can be an effective choice for augmenting vertical bone height in the atrophic mandible. More of cases and long term follow-up are needed to evaluate bone resorption and implant prognosis.
