Abstract:
Objective To measure the dimensional error of three dimensional printing maxilla models for the clinical application to oral and maxillofacial surgery.Methods The FDM 3D printing was employed to make standard geometric shape models and maxillary models.After the surface finish of both models being observed,the contour data and fineness of geometric models,as well as the distance error of bony markers between maxillary models and jaw bones specimen were measured.Results Within the 3D printing standard geometric model,the fiber arrange horizontally in X-Z,Y-Z surface and crosswise in X-Y surface,and the accuracy errors range from-1.67% to 1.47%.Moreover,the maximum resolution was 0.25 mm in X and Y axis,and 0.50 mm in Z axis.Within the maxillary model,the distance error of bony markers range from-0.08 % to 1.96 %,and the mean errors were 1.59 %,0.86%,0.42% in X,Y and Z axis respectively.The mean error in X axis was significantly larger than that in Y or Z axis (P<0.05).Conclusion 3D printing maxilla models may possess high accuracy and apply to clinical practice.
