摘要
目的研究选择性激光烧结（selectedlasersintering，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，叮以应用于临床。
Objective 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 etcsoftwareswas 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 elastomer. Results Perfect silicone elastomer 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.
