Abstract
Moderate to severe dentofacial deformities usually require combined orthodontic treatment and orthognathic surgery to obtain the most stable result with optimal function and facial esthetics. Accordingly, the orthodontist and oral maxillofacial surgeon must be able to exactly diagnose existing deformities, establish an appropriate treatment plan, and execute the recommended treatment. Especially, to obtain optimal result of the maxillary surgery, model surgery is essential. But, the preoperatively planned position of the maxillary dental arch often cannot be sufficiently achieved during actual surgery, and deviations in the sagittal and vertical dimensions are common. To achieve three dimensional repositioning of the maxilla exactly, several methods have been introduced so far. Recently Model Repositioning Instrument (MRI, SAM, Inc., $M\ddot{u}nchen$, Germany), one of these methods, has been introduced and applied clinically, which is reported as accurate, effective and prompt method for three dimensional repositioning of the maxilla. This article describes an introduction and a clinical application of this MRI.
