  • Title: [An adjustable distractor for transverse maxillary distraction osteogenesis].
    Author: Leyder P, Wycisk G, Quilichini J.
    Journal: Rev Stomatol Chir Maxillofac Chir Orale; 2013 Jun; 114(3):170-4. PubMed ID: 23827271.
    Abstract:
    INTRODUCTION: The posterior skeletal widening in conventional distractions (Surgical Assisted Rapid Maxillary Expansion) is often modest, in contrast with a predominant anterior expansion. Until recently, it was not possible to consider transverse palatal distraction osteogenesis and Le Fort I impaction or advancement in the same procedure, as the osteosynthesis plates impeded maxillary anterior opening. We developed new sliding osteosynthesis plates allowing to perform an advancement or impaction Le Fort I osteotomy associated with a low-resistance bipartite palatal distraction osteogenesis. We had for aim to describe the device and to determine its clinical applications. MATERIAL: This new palatal distractor is made up of two independent stainless steel jacks allowing for an adjustable distraction in the anterior or posterior area as needed. Bone-borne and tooth-borne versions are available. DISCUSSION: This new distractor can be adjusted sagittally. The distraction can be angular or parallel, and the distraction mode can be modified during post-operative distraction. This device should be adapted to all clinical presentations. It can be used in combination with sliding osteosynthesis to perform a Le Fort 1 osteotomy and at the same time a complete correction of vertical, horizontal, and sagittal deficiencies.
