TL;DR: Multiple linear regression analyses revealed that amount of root movement, long roots, narrow roots, abnormal root shape, and use of Class II elastics were significant risk factors, however, the statistical model had a low explained variance, strongly suggesting a weak prediction power.
TL;DR: The results of experiments in animals and clinical studies indicate that palatal mucosa and labial-buccal gingiva provide an adequate nutrient pedicle for single-stage total maxillary osteotomies.
Abstract: Adult rhesus monkeys were used as experimental analogues to investigate vascularization, revascularization, and bone healing associated with total maxillary osteotomy Microangiographic and histologic studies showed minimal transient vascular ischemia, minimal osteonecrosis, and early osseous union Transection of the greater palatine arteries had no discernible effect on the circulation to the teeth and bone in the maxilla and its enveloping soft tissues The results of experiments in animals and clinical studies indicate that palatal mucosa and labial-buccal gingiva provide an adequate nutrient pedicle for single-stage total maxillary osteotomies
TL;DR: It was concluded that distraction osteogenesis tends to be preferred to conventional osteotomy for younger CLP patients with more severe deformities and in such cases it was feasible to use distraction to correct moderate to large movement of the maxilla by either complete or incomplete Le Fort I osteotomy, and a concurrent mandibular osteotomy was less frequently required.
TL;DR: A cemented palatal expansion appliance with a bite plane is used successfully in adults up to 43 years of age, augmented with lateral maxillary osteotomy in the older ages range.
