摘　　要：目的:通过对12例下颌骨缺损患者采用个性化钛下颌修复,评价了该方法的临床可用性,探讨了在设计及临床应用中应注意的问题。方法:采用RP-SL技术及快速反求技术完成原型设计,经真空离心铸造完成钛下颌骨制备,经常规手术完成植入。结果:12例患者术后均获得良好外形,下颌功能获得恢复。2例分别于术后6月、7月出现异常,与手术无直接关系。结论:基于RP-SL技术可以个体化恢复患者面下1/3形态及功能,具有良好的临床应用前景。Objective：To evaluate the clinical applictation of rapid prototyping -stereolithography technique on 12 cases of mandibular defect patients who were treated with individual artifical titanium mandibular. Methods： To get the prototype with RP - SL technique and rapid reverse engineering, make the individual artifical titanium mandibular by vacuum centrifugal force casting, implant the individual artifical mandibular through routine operation. Results： All 12 patients obtained well face outline and their mandibular function reverted. 2 cases showed abormality in the sixth month and the seventh month, But it was not related to the operations. Conclusion： Individual reparation of mandibular based on RP - SL technique could revert low 1/3 face outline and its function . It will have a good future in clinical use .
