Highlights

  • In vitro analyses by means of imaging, software and model surgery have shown a high degree of precision in terms of the prediction of skeletal movement, but have proven impossible in transferring such strategies with similar accuracy to the patient intra-operatively

  • Ten patients underwent preoperative and post-operative measurements, which were subjected to analysis of changes in three axes by comparing them with the help of three methods

  • Other procedures included virtual surgery on a computer-generated 3D head model simulated by a computerassisted 3D virtual osteotomy system for orthognathic surgery[2], a complete 3D system of model surgery and navigation[3], computer-assisted simulation system for orthognathic surgery 2001 software for hard tissue prediction of orthognathic surgical procedures[4], computer-assisted 3D virtual reality soft tissue planning and prediction for orthognathic surgery5, 3D cephalometry[6] and 3D imaging for virtual assessment and treatment planning[7]

Summary

Introduction

In vitro analyses by means of imaging, software and model surgery have shown a high degree of precision in terms of the prediction of skeletal movement, but have proven impossible in transferring such strategies with similar accuracy to the patient intra-operatively. This study was designed to allow preoperative maxillary assessment, monitor and guide the changes intra-operatively and analyse postoperative position with the help of Op-Track. Ten patients underwent preoperative and post-operative measurements, which were subjected to analysis of changes in three axes by comparing them with the help of three methods (orthognathic planning using Erickson platform, Op-Track analysis and cephalometric analysis). The aim of this study is to evaluate the accuracy of the maxillary repositioner when used pre-operatively and post-operatively and, more importantly, to intra-operatively assess the location of the maxilla throughout the surgery. The main objective would be realized if there are no significant differences between the values obtained from the three methods (orthognathic planning, maxillary repositioning device and cephalometric analysis) for any movement in the transverse (x), anteroposterior (y) and vertical (z) planes. The repositioner can be developed further to reduce the elaborate laboratory techniques and planning time
