Vector alignment in maxillary distraction osteogenesis.
نویسندگان
چکیده
Maxillary distraction osteogenesis is an alternative treatment of cleft patients with severe maxillary hypoplasia. The aim of this paper is to present the combined surgical/orthodontic treatment of a cleft lip and palate patient and to evaluate the maxillary distraction procedure and the distraction vector in high Le Fort I osteotomy.

The role of computer-aided 3D surgery and stereolithographic modelling for vector orientation in premaxillary and trans-sinusoidal maxillary distraction osteogenesis.
BACKGROUND Maxillary distraction osteogenesis is a challenging procedure when it is performed with internal submerged distractors due to obligation of setting accurate distraction vectors. METHODS Five patients with severe maxillary retrognathy were planned with Mimics 10.01 CMF and Simplant 10.01 software. Distraction vectors and rods of distractors were arranged in 3D environment and on STL...
متن کاملInitial Experience With a New Intraoral Midface Distraction Device
Maxillary hypoplasia that necessitates surgical advancement affects approximately 25% of patients born with cleft lip and palate. Syndromic conditions such as Crouzon may also be accompanied by significant maxillary hypoplasia. Severe maxillary hypoplasia can result in airway obstruction, malocclusion, proptosis, and facial disfigurement. For optimal stability, severe hypoplasia is best address...
