Tree dimensional analysis of hard and soft issue in jaw deformity

作为应用于颌骨畸形评价和治疗的系统，硬组织和软组织的三维形态分析开发了一个有能力的系统，并进行了这项旨在临床应用的研究。获得横河Materialise和比利时Materialise的研发合作。对SimPlantCMF正颌外科手术支撑系统进行了改进。材料与方法：使用东京齿科大学千叶医院安装的多层螺旋CT进行三维分析的治疗计划数据，研究系统使用Windows XP（Pentium D 3.40GHz，Memory 3.00GB，Graphics FireGL-3100）个人计算机。我们使用SimPlantCMF的3D头影测量分析功能，设置测量点。通过向导，我们采取了截骨术，如勒堡我，SSRO之后。另外，我们可以把它放在t的位置 关于我们 通过截骨术移动骨段，并对软组织的变化进行3D模拟。结果：1.使用Wizard软件进行截骨时，除正常的三维头影测量分析点外，还需要设定其他点。2.与截骨术相比，Wizard在牵引术中的可操作性和治疗计划方面具有上级优势。3.对于面部对称的3D治疗计划的评价，实用性高于传统的2D头影测量分析。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价，与2D治疗计划相比，实用性很大，因为可以预测手术结果。结论：应用Sim Plant CMF，与现有的2D评价系统进行比较，得到以下结论。1.在三维头影测量分析中，我们很难进行与治疗目标值相匹配的评价。至于原因，与临床规范相比是不可能的。2.在模拟截骨术方面，上颌骨和下颌骨的手术是一个实用的水平，但牙槽骨的手术和SARPE是必要的。3.牵张成骨可以随意模拟器械的延伸方向和佩戴以及延伸过程，实用性很高，认为应用于骨骼三维诊断和治疗评价从研究层面进入临床层面。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.
