摘要/Abstract

摘要： 目的：探讨骨科和口腔颌面外科立体光固化（SLA）-3D打印模型的精确度，阐明该技术临床应用的可靠性。方法：随机纳入SLA-3D打印模型33例（长骨10例、不规则骨13例和假体10例），进行CT回扫并行三维重建；依据模型临床应用特点选取最大高径（MH）、最大长径（ML）、最大宽径（MW）、滑车宽径（WT）、滑车长径（LT）、关节盂长径（LGC）、关节盂宽径（WGC）、髂前上棘到耻骨结节距离（DPI）、髋臼直径（DA）、髓腔直径（DMC）、右下颌支前缘高度（AHRR）和右下颌支后缘高度（PHRR）等相关参数分别对原始数据及模型数据进行测量，计算各参数的绝对和相对误差，以组内相关系数（ICC）作为评价数据一致性指标，对假体模型进行空间误差分析。结果：33例SLA-3D打印模型中，除不规则骨组MW外，与原始数据比较，各组其他各项参数比较差异均无统计学意义（P > 0.05），模型数据与原始数据间各项参数ICC值均大于0.950，绝对和相对误差最大值分别为-0.58 mm和-1.37%；假体模型空间误差最大值为0.237 mm，总平均值为0.132 mm。结论：SLA-3D打印模型CT的数据与原始数据高度一致，其在骨科及颌面外科疾病诊疗过程中的应用准确而可靠。

Abstract: Objective: To discuss the accuracy of stereolithography (SLA) -3D printing model in orthopedics and maxillofacial surgery, and to clarify the reliability of its clinical application. Methods: A total of 33 cases of SLA-3D printing models were randomly included(10 long bones, 13 irregular bones and 10 prostheses), and the CT scanning and three-dimensional reconstruction were performed. According to the clinical application characteristics of the models, the max height (MH), max length (ML), max width (MW), width of the trochlear (WT), length of the trochlear (LT), length of the glenoid cavity (LGC), width of the glenoid cavity (WGC), distance of pubic tubercle-anterior superior iliac spine (DPI), diameter of the acetabulum (DA), diameter of the marrow cavity (DMC), anterior height of right ramus (AHRR) and posterior height of right ramus (PHRR) were selected to measure the original data and model data, respectively. The absolute/relative errors were calculated. Intraclass correlation coefficient (ICC) was used to evaluate the consistency of the data.The three-dimensional error analysis of the prosthesis model was carried out. Results: There were no significant differences in the anatomical parameters except MW of irregular bone (P>0.05) in 33 cases of SLA-3D printing model.The values of ICC were all greater than 0.950; the maximum values of absolute/relative errors were -0.58 mm and -1.37%, respectively; the maximum 3D error of prosthesis model was 0.237 mm, and the average value was 0.132 mm. Conclusion: The CT data of SLA-3D model is highly consistent with the original data, and it is accurate and reliable in the diagnosis and treatment of the diseases in orthopedics and maxillofacial surgery.
