Accuracy of Maxillary Repositioning Using Customized Maxillary Bone-Dental-Supported Guides.
The purpose of this study was to compare the accuracy of maxillary repositioning using customized maxillary bone-dental-supported guides with that using an intermediate computer-aided design and computer-aided manufacturing (CAD/CAM) splint. This retrospective cohort study included patients with dentofacial deformities on computed tomography before and 3 months after surgery. Differences between the planned and actual postoperative positions of the maxilla were measured using simulation software for 3 landmarks. Twenty-two patients were treated using customized maxillary bone-dental-supported guides (group A) and 22 patients were treated using intermediate CAD/CAM splints (group B). For all 3 axes, discrepancies for all 3 landmarks tended to be smaller in group A than in group B. In particular, intermediate splints, calculated over the 22 cases and all 3 landmarks, showed significantly larger discrepancies on all 3 axes than the customized maxillary bone-dental-supported guides, calculated over the 22 cases and all 3 landmarks. In conclusion, customized maxillary bone-dental-supported guides appear more effective than intermediate CAD/CAM splints in achieving accurate transfer from 3D simulation to real surgery.
期刊介绍：
The Journal of Craniofacial Surgery serves as a forum of communication for all those involved in craniofacial surgery, maxillofacial surgery and pediatric plastic surgery. Coverage ranges from practical aspects of craniofacial surgery to the basic science that underlies surgical practice. The journal publishes original articles, scientific reviews, editorials and invited commentary, abstracts and selected articles from international journals, and occasional international bibliographies in craniofacial surgery.
