Abstract

Introduction: Patients with oroantral fistula usually have severe alveolar bone defects. Alveolar bone augmentation procedure may be needed when placing implant in atrophic bone. Currently, various alveolar bone augmentation techniques are recognized as promising treatments. The purpose of this study is to evaluate the results of simultaneously performed sinus augmentation, guided bone regeneration (GBR) and block bone graft procedures in patient who have the severe alveolar bone loss with oroantral fistula.

Case: A 58-year-old male patient was referred for implant removal at #15, 16 intruded in the right maxillary sinus. At first, implant fixture was removed and, #14 was extracted. After 7 months, combination technique including sinus augmentation & block bone graft & GBR was carried out. Sinus augmentation was performed by the lateral approach. The bone block harvested from the mandibular ramus was performed. The bone block is placed on the alveolar bone and fixed with a screw to the alveolar bone with GBR. At 7 months after bone augmentation, Implants were placement at the #14, 16, 17 edentulous site. After implantation 6 months, implant second operation was done. And the prosthetic procedure was completed.

Conclusion: Healing occurs without complications and at 9 months follow-up check, normal clinical and radiological findings were observed.
