Surgical occlusion setup and skeletal stability of correcting cleft-associated class III deformity using surgery-first bimaxillary surgery.

The surgical occlusion for correction of cleft-associated class III deformity using the surgery-first approach was characterized with large overjet and positive overbite, and posterior cross bite and open bite. On average, there was occlusal contact on four to five teeth; half of surgical occlusion setups had contact on three segments. The post-surgical skeletal stability was not related to the surgical occlusal contact but to the surgical skeletal movement.
