Virtual Surgical Planning Assisted Management for Three-Dimensional Dentomaxillofacial Deformities

Objective: 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. Study Design: 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. Result: 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. Conclusion: 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.
