目的
探讨应用反求工程(RE)和快速成型(RP)技术制作的个体化钛下颌人工骨修复下颌骨缺损的临床效果。
方法
选择2007 ~2009 年中山市人民医院收治的下颌骨肿瘤病例6 例,通过CT 扫描加三维重建采集病变下颌骨的测量数据,按照手术设计在数字模型上切除病变骨段,形成下颌骨缺损模型,通过数字镜像得到植入体的数字模型,利用RP技术获得树脂实体模型并进行包埋铸造获得个体化人工骨。
结果
术前利用RE 和RP 技术制作个体化下颌人工骨快速精确,术中就位顺利,手术创口均为Ⅰ类愈合,术后随访7 ~30个月,缺损区面部外形恢复满意,开口度3.2 ~3.6 cm,咬合关系正常,张口无偏斜。
结论
应用RE 和RP 技术制作个体化人工骨修复下颌骨缺损,方法简便精确,能达到外形与功能兼备的临床效果。
Objective
To evaluate the clinical results of individualized artifical titanium mandible produced by rapid prototyping (RP) and reverse engineering (RE) technology.
Methods
Six patients with mandiblar tumors and underwent surgery at the Department of Oral and Maxillofacial Surgery, People's Hospital of Zhongshan City, from 2005 to 2007 were selected.Measurement data of mandibular lesions were collected by CT scan and three-dimensional reconstruction.Bony lesions segments were removed in the digital model according to operation design.The mandibular defect models were made.Digital models of the implants were obtained by digital image technology.Resin models were obtained by rapid prototyping technique and used for casting of individual artifical mandible.
Results
The artifical mandibles produced by rapid prototyping fit in place quickly and accurately during surgery.All patients achieved one stage healing.After a follow-up of 7 to 30 months, mandibular defects were reconstructed satisfactorily and the mouth opening was 3.2 - 3.6 cm.The occlusions were normal.
Conclusions
RE/RP technology is feasible and accurate for reconstruction of discontinuous mandible.Individualized artifical mandible can fulfill the requirements of anatomy and function in mandible reconstruction.
