Abstract

Long-term sequelae of chemical burns in oral cavity can result in severe alveolar bone defects. This case report presents a patient who was 40 years previously burnt with sulfuric, and developed multiple root resorption and a palatal segmental bone defect in the right maxillary anterior and premolar regions without any pathological lesions. Surgical intervention involved the extraction of hopeless teeth (#12, #13, #14), elevation of the palatal soft tissue as a flap, and reconstruction using autogenous ramal cortical bone combined with an allogenic bone graft and covered with a resorbable membrane. Following the healing period, two dental implants were placed at positions 13 and 14 , and a three-unit fixed dental prosthesis was delivered. Complete bone regeneration was achieved and maintained over a 3-year follow-up period. The implants demonstrated excellent stability and satisfactory aesthetic and functional outcomes. Radiographic examination confirmed complete osseointegration and volume stability of the grafted area. This case showed that ramal cortical bone when combined with allogenic bone and covered by healthy palatal tissue, can successfully reconstruct segmental alveolar defects. The use of indigenous palatal soft tissue as a covering flap has proven to be critical for achieving predictable bone regeneration and long-term volume stability.
