摘要目的 研究选择性激光烧结(selected laser sintering,SLS)法烧结复合蜡粉(PCPI)进行鼻缺损硅橡胶赝复体的制作及临床应用.方法 采用三维激光扫描仪扫描鼻缺损的石膏模型获得三维数据,在计算机软件中进行数据处理,镜像反求获得缺损的三维模型,并进行三维实体重建,用SLS法烧结PCPI制作鼻缺损蜡模型.并进一步制作出硅橡胶鼻赝复体.结果 2例外鼻缺损患者取得了与原鼻完全吻合的硅橡胶赝复体.结论 用SLS法烧结PCPI所得的鼻蜡模型基本符合临床赝复体制作的要求,可以应用于临床.

abstractsObjective To explore the clinical application of reconstructing silicone elastomer nose prosthesis by means of selected laser sintering and wax powder PCPI. Methods Laser scanning was used to get the 3-D data of a nose model. Surfacere 10.0 etc softwares was used to reconstruct the nose by mirroring the digitalized model of absent nose. Selective laser sintering and wax powder was chosen to fabricate a wax nose model and the nose prosthesis made by silicone clastomer. Results Perfect silicone clastomer nose prosthesis was made for 2 patients. Conclusion This study suggests that the wax nose model and the new wax powder can meet the requirement of clinical expectation for maxillofacial prosthesis.
