Edentulous ridge space closure after bone augmentation using different graft materials: A report of two cases

Abstract

Abstract Post-extraction alveolar ridge resorption is a common sequela when missing mandibular molar spaces are not managed in a timely fashion. The situation becomes more complicated in patients who seek orthodontic treatment if closure of the edentulous space is the major objective in order to avoid prosthetic rehabilitation. In the present article, two cases are reported, in which different bone augmentation graft materials were used and treatment duration and post-orthodontic alveolar ridge characteristics were compared. A regional acceleratory phenomenon after the grafting procedure facilitated uneventful orthodontic space closure. The status of the investing alveolar bone was compared using post-treatment cone-beam computed tomography. Both autogenous bone graft and allograft ridge augmentation procedures aided in successful molar protraction through the resorbed mandibular alveolar ridge, as well as preventing periodontal attachment loss.
