目的：评价多层标准化选择性激光烧结（SLS）技术制作颅面三维模型的准确性。材料与方法：19个模型均经多层螺旋CT（MSCT）检查。分析用于3D建模的患者CT数据，并与3D模型数据进行比较。定义了15个解剖标志，并对20个距离进行了数字测量。将两组CT数据集的数字测量值与SLS模型的手动测量值进行比较。
Purpose: To evaluate the accuracy of craniofacial 3D models produced in the standardized selective laser sintering (SLS) technique from multislice. computed tomography (MSCT) data sets in comparison with patient data and to investigate the effect of potential causes of inaccuracies.Materials and Methods: 19 models were considered and examined by MSCT. The patient CT data used for 3D modeling was analyzed and compared to the 3D model data. 15 anatomical landmarks were defined and 20 distances were digitally measured. The digital measurements of both CT data sets were compared to manually measured distances of the SLS model.Results: There was not a statistically significant difference (p
