“…Other medical applications include interpersonal communication training, anatomy instruction, exposure therapy, and pain management 13–17 . VR educational tools for maxillofacial surgery planning have been developed 18–22 . However, the available tools are few in number and the use of VR technology in dentistry is still in its infancy.…”

Purpose Advances in virtual reality technology for surgical simulation methods may improve diagnosis and treatment planning of complex orthognathic surgery cases. The objectives were to assess orthodontic residents’ performance and attitudes when treatment planning orthognathic surgery cases using two‐dimensional (2D) digital, three‐dimensional (3D) digital, and virtual reality (VR) surgical simulations. Methods The study had a mixed methods study design involving 20 graduate orthodontic residents. Their previous experiences, confidence, and competence with orthodontic diagnosis and surgical treatment planning were assessed with a baseline survey. Each resident completed 2D, 3D, and VR treatment planning and simulation tasks in a randomized order and recorded their diagnosis, objectives, treatment plan, and special surgical concerns for each case using a treatment planning worksheet. The worksheets were scored and quantitative data were analyzed. Attitudinal responses to the simulation experience were captured with a post‐survey and interview. Results The number of total prescribed surgical movements was greater for 3D and VR simulation methods (p = 0.001). There were no differences in the overall total written treatment plan analysis score among the three surgical simulation tasks. Participants took longer to complete the VR and 3D tasks (p < 0.001) and asked more questions regarding manipulation (p < 0.001) and software features (p < 0.002) for higher fidelity tools. Analysis of qualitative feedback showed positive attitudes toward higher fidelity tools with regard to visualization, manipulation, and enjoyment of the task. Conclusions The results demonstrate that simulation methods of increased fidelity (3D and VR) are appropriate alternatives to 2D conventional orthognathic surgical simulation methods when combined with traditional records. Qualitative feedback confirms residents’ readiness to adopt VR simulation. However, comprehensive training is needed to increase familiarity and comfort with using the new technology.

“…To support the planning of therapeutic interventions, exact planning and simulation software has been developed on the basis of diagnostic ®ndings and almost realistic patient models stored in data bases [7][8][9][10][11]. To this effect, innovative methods of virtual and augmented reality can be used [12,13]. It is possible to preoperatively simulate different operative strategies and their results, resulting in patient-speci®c planning and individual optimization of the surgical tactics.…”

Computers used as supporting tools for diagnostics, operation planning and therapy are of increasing relevance in surgery. Rapid progress in imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRT) and ultrasound already allows to represent anatomical and physiological conditions with maximal authenticity. In order to simulate complex surgeries we must develop ergonomic and intuitively useable software tools, thus enabling a precise and fast virtual execution of the planned surgical intervention preoperatively. Intraoperative support will consist of passive navigation tools, available already today, supporting the intraoperative orientation and, in the future, robots performing specific steps autonomously. Methods of augmented reality for the interaction of virtual objects and the real surgical scene are also suitable for the visualization of planning data and other medically relevant information in the operation situs. In maxillofacial and craniofacial surgery the techniques mentioned have been applied in all fields from dental implantology up to the correction of craniofacial malformations and the resection of skull base tumors. Many applications are still being developed or are still in the form of a prototype. However, it is already clear that developments in this area will have a considerable effect on a surgeon's routine work.
