Tree dimensional analysis of hard and soft issue in jaw deformity

作为一个应用于颌骨畸形评估和治疗的系统，对硬组织和软组织的三维形态进行了分析，开发了一个功能强大的系统，并进行了旨在临床应用的研究。我们获得横河物化和比利时物化的研发合作。对正颌外科手术支持系统SimPlantCMF进行了改进。我们扩展了一款辅助种植牙手术的软件的功能，并在本研究中开发和使用了该软件。材料与方法：使用东京牙科大学千叶医院安装的多层螺旋CT，获取治疗计划数据，其中包括三维分析。学习系统使用Windows XP(奔腾D 3.40 GHz，内存3.00 GB，图形FireGL-3100)的个人计算机。使用SimPlantCMF的三维头影测量分析功能，设置测量点。在巫师的带领下，我们采取了Le Fort I等截骨术，后来又进行了SSRO手术。另外，我们可以把它放在t…的位置更多的是通过截骨移动的骨段，并三维模拟软组织的变化。结果：1.使用WANIZE进行截骨术，除需要一个正常的三维头影测量分析点外，还需要一个设定点。2.与截骨术相比，WIZER在牵张方面优于手术和治疗方案。3.对于面部对称性三维治疗方案的评估，其实用性高于传统的2D-头影测量系统。在颌骨畸形的治疗中，我们对颅骨的上下颌位置关系进行了三维评估，并将其与2D治疗方案进行了比较，其实用性较大，因为可以预测手术结果。结论：将Sim Plant CMF与现有的2D评估系统进行比较，得出了以下结论。1.对于三维头影测量分析，我们的评价很难与治疗目标值相匹配。至于原因，与临床常模相比是不可能的。2.在模拟截骨方面，上颌骨和下颌骨手术是一个实用层面，但牙槽骨手术和SARPE手术是必要的。3.牵引成骨技术可以随意模拟装置的伸展方向、磨损和伸展过程，实用性很高，将其应用于骨骼三维诊断和治疗评价从研究层面上升到临床层面。较少

As a system to apply to evaluation of jaw deformity and treatment, analysis of three dimensions form of a hard and a soft tissue developed a capable system, and this study to be aimed for the clinical application was performed. We obtained research and development cooperation of Yokogawa Materialise and Belgian Materialise. We improved SimPlantCMF which was the orthognathic surgery support system. We expanded a function of software to help an operation of dental implant and developed and used it for this study.Material ＆ Method : The treatment plan data which we included 3D analysis in used multi-slice CT installed in Tokyo Dental College Chiba Hospital and obtained it. A study system used a personal computer with Windows XP (Pentium D 3.40GHz, Memory 3.00GB, Graphics FireGL-3100). We used a 3D-cephalometric analysis function of SimPlantCMF, set a measure point. By Wizard, we took osteotomy such as Le Fort I, the SSRO afterwards. In addition, we could put it together at a position of t … More he bone segment which moved by osteotomy, and 3D-simulated a change of a soft tissue. Furthermore, we reviewed face soft tissue form from real postoperative CT and an agreement of a prediction image.Results:1.There was need to set point except a normal 3D-cephalometric analysis point to take osteotomy by Wizard. 2.Wizard was able to be superior to operability and a treatment plan in Distraction in comparison with Osteotomy. 3.For evaluation of facial symmetric 3D treatment plan, a utility was a high system than a conventional 2D-cephalometric analysis.In treatment of jaw deformity, we evaluated position relations of maxilla and mandible for a skull for three dimensions, and the utility was big when we compared it with a treatment plan in 2D because a prediction of operation results was enabled.Conclusion : It was to apply Sim Plant CMF and got the following conclusions in comparison with an existing 2D evaluation system. 1.About a 3D-cephalometric analysis, the evaluation that we matched with the therapeutic targeted value was difficult. As for the reason, comparison with clinical norm is impossible. 2.About simulation of osteotomy, the operation of a maxilla and mandible bone was a practical use level, but an operation of alveolar bone and a SARPE are necessary. 3.A distraction osteogenesis could simulate an extension direction and wearing of device and an extension course carelessly, and a utility was very high.It was thought that application to skeletal three-dimensional diagnosis and treatment evaluation became a clinical level from a study level.
