[The orthodontic conditions for late-primary osteoplasty in cheilognathopalatoschisis].

Pre- and postoperative orthodontic treatment at the time of labioplasty and palatoplasty are essential preconditions for a late-primary osteoplasty. As confirmed in my study this is important to achieve a sufficient base of the cleft jaw and a corresponding alveolus bone. Further conditions are a) the absence of the sagittal and transversal contractions of the cleft jaws and of cross-bites following labioplasty or/and palatoplasty, b) the proximity of germs to the cleft, c) the discrepancy between teeth and jaw size, and the indication for the extractions of teeth. Maxillary micrognathia require osteotomy.
