【摘要】：目的分析3D打印上颌骨手术模型的误差,为口腔颌面外科3D打印技术的应用提供基础数据支持。方法应用熔纤3D打印技术制作标准几何模型和上颌骨模型,观测两种模型的表面光洁度,测量几何模型的外形数据和精细度,测量上颌骨模型与颌骨标本骨性标志物间的距离误差。结果 3D打印标准几何模型的表面X-Z、Y-Z平面呈水平排列,X-Y平面呈经纬交错排列,精度误差率在-1.67%~1.47%;最高解析度X及Y轴边长为0.25mm,Z轴边长为0.50mm。3D打印上颌骨模型骨性标志点间距离的误差率在-0.08%~1.96%,X轴向上误差率均值为1.59%,Y轴为0.86%,Z轴为0.42%,X轴误差率显著大于Y、Z轴(P0.05)。结论 3D打印技术制作上颌骨模型具有很高的精确度,通过合理设计可以提高模型制作精度来满足临床需要。
[Abstract]:Objective to analyze the error of 3D printing model for maxillofacial surgery, and to provide basic data support for the application of 3D printing in oral and maxillofacial surgery. Methods the standard geometric model and maxillary model were made by using fused fiber 3D printing technology. The surface finish of the two models was observed and the shape data and fineness of the two models were measured. The distance error between maxillary model and bone marker of maxillary specimen was measured. Results the surface of the 3D standard geometric model was arranged horizontally, and the X-Y plane was staggered between longitude and weft. The accuracy error rate is -1.67 / 1.47, the maximum resolution X and Y axis side length are 0.25 mm / Z axis length and 0.50mm.3D print the distance between the bone mark points of maxilla model. The average error rate is 1.59Y axis 0.86Y axis 0.86X axis error rate is 0.42X axis error rate is significantly higher than that of Y axis P0.05U axis P0.05a, the average error rate is 1.59Y axis 0.86Y axis 0.86X axis error rate is 0.42X axis error rate is higher than that of Y axis and Y axis 0.25mm / Z axis length is 0.25mm / Z axis length and Y axis length is 0.25mm / Z axis length. Conclusion 3D printing technique has a high accuracy in making maxillary model, which can be improved by reasonable design to meet the clinical needs.
