Tree dimensional analysis of hard and soft issue in jaw deformity

作为一种应用于颌骨畸形评估和治疗的系统，对软组织和硬组织的三维形态进行分析，形成了一套有能力的系统，本研究旨在为临床应用而进行。获得横河物化、比利时物化的研发合作。我们改进了SimPlantCMF，这是一个正颌手术支持系统。我们扩展了一个帮助种植牙手术的软件功能，并开发并应用于本研究。材料与方法：我们在东京牙科学院千叶医院安装的二手多层螺旋CT上进行三维分析并获得治疗方案数据。研究系统使用的个人电脑为Windows XP （Pentium D 3.40GHz，内存3.00GB，图形FireGL-3100）。我们使用SimPlantCMF的3d头测量分析功能，设置一个测量点。通过Wizard，我们采取了Le Fort I等截骨术，之后进行了SSRO。此外，我们可以将其放在t…的位置，更多的是通过截骨移动的骨段，3d模拟软组织的变化。此外，我们还回顾了术后真实CT面部软组织形态和预测图像的一致性。除正常的3d头颅测量分析点外，Wizard还需要一个定点进行截骨。与截骨术相比，向导术在牵张术的可操作性和治疗方案上更胜一筹。对于面部对称的三维治疗方案的评估，一个实用程序是一个高系统比传统的二维头测量分析。在颌骨畸形的治疗中，我们对颅骨的上颌骨和下颌骨的位置关系进行了三维评估，当我们将其与二维治疗计划进行比较时，实用性很大，因为可以预测手术结果。结论：应用Sim Plant CMF，与现有二维评价体系进行对比，得出以下结论：1.关于3d头颅测量分析，我们很难评估与治疗目标值相匹配。究其原因，无法与临床规范进行比较。2.在模拟截骨术中，上下颌骨的手术是实际应用的水平，但牙槽骨的手术和SARPE是必要的。3.牵张成骨术可以随意模拟器械的伸展方向、磨损和伸展过程，具有很高的实用性。认为应用于骨骼三维诊疗评价已从研究层面上升到临床层面。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.
