OBJECTIVE
The purpose of this study was to explore a new method to repair mild mandibular asymmetry using computer-aided design technique.
METHODS
Medical three-dimensional image reconstruction and mirror technique were applied to design individual Medpor implant before operation. A surgical procedure was performed in 9 patients with mild mandibular asymmetry according to the preoperative planning. The Medpor implants in the body were displayed using surface rendering technique after operation, and the postoperative evaluation was performed using matching technique.
RESULTS
All the patients had an ideal clinical outcome, with no complications. Virtual images from preoperative design and postoperative three-dimensional images were registered and superimposed onto each other. The percentage of matching was 87.6% to 96.8% with an average of 93.8%±2.4%.
CONCLUSIONS
The computer techniques play an important role in repairing mandibular asymmetry and will be used widely in craniofacial surgery.
目的
本研究旨在探索一种利用计算机辅助设计技术修复轻度下颌骨不对称的新方法。
方法
术前应用医学三维图像重建和镜像技术设计个体化Medpor植入物。根据术前规划，对9例轻度下颌骨不对称患者实施手术。术后采用表面渲染技术显示体内的Medpor植入物，并采用匹配技术进行术后评估。
结果
所有患者均获得理想的临床效果，无并发症发生。术前设计的虚拟图像与术后三维图像进行配准并相互叠加。匹配率为87.6%至96.8%，平均为93.8%±2.4%。
结论
计算机技术在修复下颌骨不对称中发挥着重要作用，将在颅面外科中得到广泛应用。
