Localized Ridge Augmentation with Mandibular Block Autograft and Guided Bone Regeneration: A Case Report

Abstract

Numerous alveolar ridge defects resulted post extraction, long standing periodontal disease often require surgical intervention before prosthetic rehabilitation. On the other hand, alveolar bone defects affect the prognosis of dental implants and as a result, their reconstruction is must. Although a wide variety of options have been invented, autogenous bone is still the gold standard and has been yielding promising results. The authors report a case of localized alveolar ridge augmentation using autogenous chin block graft in conjunction with other bone substitutes for prosthetic rehabilitation of lower anterior region. Initially, the alveolar ridge was knife edge and the bone volume was insufficient for placement of dental implant. The CBCT analysis post 6 months shows significant increase in bone volume that was now suitable for prosthetic rehabilitation of the edentulous space.
