Abstract:
Objective To develop and validate a new genioplasty templates system for monoblock osseous genioplasty.Methods Thirty-six patients with chin deformities were enrolled in this study.The chin template system included a cutting guide and a repositioning guide for a genioplasty.Chin templates were designed in a computer and fabricated using a three-dimensional printing technique.The accuracy of the genioplasty templates were assessed by comparing the actual postoperative outcomes with the virtual plan.Results All genioplasty was successfully completed by the template system.The largest linear rootmean-square deviation(RMSD) between the planned and the postoperative chin segments was 1.16 mm and the largest angular RMSD was 3.06°.Conclusions The results showed that the chin template system provides a reliable method for transfer of genioplasty planning.The operation precision of the genioplasty can be improved by using the surgical templates system.
