摘　　要：利用3D打印技术制作了定制化的骨缺损替代物塑型器,并通过三坐标测量仪对基于该塑型器制备出来的模型进行测量,与手工制作的骨缺损替代物模型和基于患者的CT数据重构的三维模型进行对比。结果表明:基于塑型器制作的骨水泥模型与重构的三维模型的误差小于1.96%,而手工制作的骨水泥与重构的三维模型的误差为24.7%。采用3D打印制作定制化骨水泥塑型模具,不但能提高骨水泥模型与患侧部位形状的相似程度,而且能有效避免在术中多次调整植入物大小和位置而导致的患者二次创伤,从而提高手术的安全性。A shaping mold to make a customized implant for bone defect was designed and built by3D printing. The model built by shaping mold was measured by the coordinate measuring machine. The manual build bone cement and 3D model reconstructed through the patient′s CT data were compared to analyze the accuracy. The results show that the error between the model of bone cement built with shaping mold and the reconstructed 3D model of the bone is less than 1.96%,the error of manual reconstruction of the bone cement and reconstructed 3D model is 24.7%. Using 3D printing to make customized bone cement shaping mold can not only improve the similarity between the cement model and the shape of the affected part,but also effectively prevent secondary trauma to the patient caused by multiple adjustments of implant size and position during the operation,also improve the safety of surgery.
