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.
