Case I
Nearly a year into her orthodontic treatment, a 30-year-old woman with a history of TP and TM(Fig. 1) who had her upper premolars and lower left premolar extracted noticed bony outgrowths on the buccal mucosa during the space closure stages (Fig. 2). A provisional diagnosis of ABE was obtained after a clinical examination, and it was agreed to carry on with regular orthodontic treatment. In order to see if spontaneous remission occurs, all orthodontic forces were stopped at the end of orthodontic therapy. The ABE spontaneously regressed after two months of force cessation (Fig. 3). Once normal alveolar and gingival architecture was attained, the patient was debonded.
