Decortication Assisted Orthodontic Treatment for Bimaxillary Dentoalveolar Protrusion
Keywords:
Decortication, Corticotomy, bimaxillary protrusion, Orthodontic treatmentAbstract
Bimaxillary protrusion is a condition characterized by protrusive and proclined upper and lower anterior teeth and an increased procumbency of the lips. Many patients with bimaxillary protrusion seek orthodontic treatment to decrease this procumbency; correction might involve removal of 4 premolars and retracting the anterior segments to reduce lips protrusion. However, during retraction, the characteristics of the anterior alveolar bone can resist the efforts to remodel bone. Also, orthodontic treatment requiring closure of extraction space has a high risk of side effects. Corticotomy, alveolar augmentation, and orthodontic treatment. They have noted that orthodontic tooth movement is accelerated by the increase of bone turnover and decrease of bone density. It is interesting that corticotomy. Can remove some limits to tooth movement in bimaxillary protrusion patients.
