Horizontal Ridge Augmentation in Class III Alveolus Defect According to the Elian and Tarnow Classification

Guided bone regeneration (ROG) is the process of reconstructing bone defects. The size of the alveolar ridge can be affected by loss of alveolar bone due to trauma or periodontal disease. In this case report, horizontal ridge augmentation with a xenograft and resorbable collagen membrane was used to restore anterior bone loss in a 69-year-old patient with stage IV generalized periodontitis, stage B periodontitis and stage III alveolar defects according to Elian and Tarnow. Treatment consisted of the extraction of the affected teeth. The results obtained over six months showed an increase in the horizontal ridge of 4.8 mm, demonstrating the efficacy of ROG in alveolar defects. Finally, the results of this case highlight the potential of ROG for horizontal flanges.
