“…We used the same system to control the position of the maxilla after Le Fort I osteotomies and we quantified the discrepancies of the occlusal splint for this indication. 10 The aim of our study was to show that the Orthopilot™ improves the accuracy of a traditional occlusal splint for maxillary repositioning during Le Fort I osteotomy.…”

“…Orthognathic surgery has traditionally been associated with complex presurgical laboratory work that was succeptible to error and could subsequently complicate intraoperative care and compromise outcomes. 8 In their 2005 paper, Zins et al 9 reported that orthognathic surgery is a poorly reimbursed procedure, making these cases financially less practical for the plastic surgeon. In fact, it has been argued that when the additional time for laboratory work is considered, jaw surgery is one of the most poorly reimbursed procedures in plastic surgery.…”

The evolution of virtual surgical planning (VSP) in the last 2 decades has led to improved precision and efficiency for orthognathic surgery, both pre-and intraoperatively. This study evaluates a single surgeon's experience with this technology over the past 6 years. Patients undergoing orthognathic surgery using VSP with the senior author between 2015 and 2021 were retrospectively reviewed. Virtual surgical planning -specific data including incidence of midline/cant correction, occlusal equilibration, serial splints, segmental osteotomies, and custom plates were recorded and analyzed. Sixty patients undergoing orthognathic surgery using simulated VSP in the study period were retrospectively reviewed. Mean age at time of surgery was 23.5 ± 7.9 years. Forty-nine patients (81.7%) underwent LeFort I osteotomy combined with at least 1 additional procedure (eg, unilateral or bilateral sagittal split osteotomy, condylectomy, genioplasty, etc.). Twenty-six (43.3%) of patients in the studied cohort underwent maxillary midline correction, 30.0% required occlusal equilibration, 36.7% underwent maxillary molar cant correction, 30.0% underwent mandibular cant correction, and 21.7% required both maxillary and mandibular cant correction. Three patients required serial splinting, and 15 patients (25.0%) required modification of splint design. Custom plates were utilized in 15 patients (25.0%). This study demonstrates the utility of VSP in accurately detecting occlusal cants, asymmetry, and occlusal interferences. Virtual surgical planning also allows for From the

“…VSP can overcome the potential difficulties in articulator model surgery (17,46) or inaccuracy of the articulator-based conventional model surgery (47). For example, when a maxillary down fracture or asymmetric maxillary impaction with down fracture on the contralateral side are needed, they are definitely accompanied by premature contact with bilateral or unilateral molars.…”

Although there are many benefits to use 3D virtual surgical planning (VSP) for orthognathic surgery, there are only a few reports on the potential errors or mistakes that can occur with VSP and simulation processes. This narrative review updates information on VSP and discusses the various precautions and considerations for VSP in orthognathic surgery. Application of VSP allows visualization of the interosseous relationship, segment overlap or bony interference, and significant interosseous gaps.Potential sites for additional bone grafts or bone reduction can be anticipated. Additionally, presurgical planning can be performed with unlimited time. Since most VSP is performed by an outsourced company, quality assurance in VSP depends on a third-party, and sometimes there is lack of clarity when delineating the responsibilities for surgical outcomes. To increase the precision of 3D planning and simulation, surgeons need to be aware that the VSP cannot automatically ensure the success of surgical outcomes. Errors can occur at every step, such as integration of 3D dentition to skull data, segment identification and mobilization, computer-aided surgical simulation, fabrication of splint and surgical guides, 3D image superimposition, and determination of occlusion in virtual space. Thorough understanding of the source of errors in VSP can lead to successful surgical outcomes in orthognathic surgery performed with VSP.
