Intraoral distraction osteogenesis for maxillary and mandibular deformities / 实用口腔医学杂志

ABSTRACT

Objective:To describe the application of intraoral di st raction osteogenesis for correction of maxillofacial and mandibular deformities . Methods: 5 cases with serious maxillofacial or mandibula r deformities underwent distraction by using 2 types of intraoral distraction d evice.Mandibular lengthening and maxillary widening for micrognathia and maxilla ty constriction was performed in 1 case with Treacher Collions syndromes. M axillary distraction osteogenesis for maxillary hypoplasia in 2 cases.Simultaneo us maxillary and mandibular distraction in 1 case with hemifacial microsomia. T ransport distraction for mandibular body rectangle defect in 1 case. Results: Satisfactory morphologic results were achieved in all patients with good facial symmetry, ad equate occlusal relationship without any complication.Conclusions: Intraoral distraction osteogenesis provides a safe and effective treatment for the reconstruction of facial morphologic and occlusal relationshi p.
