摘要
目的 :研究选择性激光烧结 (selectedlasersintering ,SLS)法烧结新型复合蜡粉 (PCP1)进行鼻石膏模型的蜡模型快速成型及鼻硅橡胶赝复体的制作。方法 :采用三维激光扫描仪扫描鼻石膏模型获得鼻三维数据并进行三维实体重建 ,用选择性激光烧结法烧结蜡粉制作鼻蜡模型 ,并制作出硅橡胶鼻赝复体 ,对蜡模型及硅橡胶鼻进行测量 ,比较与原石膏模型的差异。结果 :取得了与原石膏模型基本一致的鼻蜡模型及硅橡胶赝复体。结论 :用SLS法烧结复合蜡粉所得的鼻蜡模型符合赝复体制作的要求 ,可以应用于临床。
Objective:To reconstruct a 3-D wax nose model and make a s ilicone elastomer nose prosthesis. Methods:Laser scanning was us ed to get the data of a nose model, selective laser sintering and wax powder wer e used to fabricate a wax nose model,the nose prosthesis was made by silicone el astomer. The differences in length(L),width(W),deepth(D),height(H) and tip-angl e(TA) among the nose models made with plaster, wax powder and silicone elastomer were compared. Results:L(mm) in plaster, wax and silicon e models was 36.61,36.60 and 36.60 respectively.W(mm),D(mm),H(mm) and TA(°) in the three kinds of models were the same:36.23,18.45,43.14 and 74.57 respectively .Conclusion:Nose model made of the wax powder is precise and can meet the requirements for maxillofacial prosthesis.
