Treatment of 3-dimensional dentomaxillofacial deformities remains a significant clinical challenge. This retrospective study aims to present the modalities of management for complex 3-dimensional dentomaxillofacial deformities with the assistance of virtual surgical planning (VSP) and 3-dimensional printed navigation templates.
Ten patients diagnosed with complex 3-dimensional dentomaxillofacial deformities received treatment of combined orthodontics and orthognathic surgery. Various surgical techniques as well as bone graft and distraction osteogenesis were used under the guidance of VSP and 3-dimensional printed navigation templates according to the characteristics of each patient. Follow-up included clinical examination and studies of spiral computed tomography preoperatively and for an average of 12 months postoperatively.
The clinical outcomes of patients showed that VSP was successfully transferred to actual surgery in all the 10 patients. Three-dimensional dentomaxillofacial deformities were corrected significantly. Satisfactory profiles and occlusion were achieved.
The management of 3-dimensional dentomaxillofacial deformities required comprehensive consideration and detailed surgical planning. Virtual surgical planning serves as a reliable assistance in the management of 3-dimensional dentomaxillofacial deformities.
三维牙颌面畸形的治疗仍然是一项重大的临床挑战。本回顾性研究旨在介绍在虚拟手术规划（VSP）和三维打印导航模板辅助下治疗复杂三维牙颌面畸形的方法。
10例被诊断为复杂三维牙颌面畸形的患者接受了正畸与正颌联合手术治疗。根据每位患者的特点，在VSP和三维打印导航模板的引导下，采用了各种手术技术以及骨移植和牵张成骨术。随访包括术前临床检查和螺旋计算机断层扫描研究，以及术后平均12个月的研究。
患者的临床结果表明，VSP在所有10例患者中均成功转化为实际手术。三维牙颌面畸形得到显著矫正。实现了满意的外形和咬合。
三维牙颌面畸形的治疗需要综合考虑和详细的手术规划。虚拟手术规划在三维牙颌面畸形的治疗中是一种可靠的辅助手段。
