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.
