Introduction: Alveolar ridge defects resulting from tooth extraction, trauma, or periodontal disease often require surgical correction prior to prosthetic reconstruction. Posterior ridge deficiencies are challenging defects to treat. Therefore, augmentation of deficient alveolar ridges is an important aspect regardless of whether implants or conventional fixed prosthetic treatment is being planned. Several techniques have been used to augment the bone volume, including bone grafts from extra oral and intraoral sites, guided bone regeneration with bio-resorbable or non-resorbable membrane and alveolar distraction osteogenesis.
Materials and Method: This case report describes the management of a localized maxillary posterior alveolar ridge defect. The deficient site was augmented using autogenous particulate chin graft along with placement of bio-resorbable membrane- Sybograf-GBR (Guided bone regeneration). Pre- operative radiograph was taken to assess ridge deficiencies in the edentulous areas.
Results and Conclusion: Six months post-operative clinical and radiographic examination revealed a significant increase in height and width of alveolar ridge in the edentulous area.
 The results showed that combined treatment modalities using autogenous chin graft and GBR membrane is beneficial for the treatment of localized posterior alveolar ridge defects.
