Abstract

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.

定制上颌骨-牙体支撑导具对上颌复位精度的影响

本研究的目的是比较使用定制的上颌骨-牙支撑导轨与使用中间计算机辅助设计和计算机辅助制造（CAD/CAM）夹板的上颌重新定位的准确性。这项回顾性队列研究包括手术前和手术后3个月计算机断层扫描显示的牙面畸形患者。使用模拟软件测量3个地标的上颌骨计划位置与术后实际位置的差异。22例患者使用定制的上颌骨-牙支撑支架（A组），22例患者使用中间CAD/CAM夹板（B组）。在所有3个轴上，A组的所有3个标志的差异都比b组小，特别是在22例和所有3个标志上计算的中间夹板在所有3个轴上的差异都明显大于定制的上颌骨-牙支撑导轨在22例和所有3个标志上计算的差异。综上所述，在实现从3D模拟到真实手术的准确转移方面，定制的上颌骨-牙支撑导向比中间CAD/CAM夹板更有效。

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.
