Virtual surgical planning (VSP) has been a significant evolution in orthognathic procedures, transforming the way surgeons approach complex corrections. This technology not only streamlines the workflow but also improves accuracy and efficiency in surgical outcomes. A comprehensive VSP workflow involves several steps, including the use of intraoral fiducial markers, clinical photography, and the digital transfer of occlusal data. These tools are used to create precise surgical plans that can be superimposed on postoperative scans to assess the accuracy of the surgical intervention.
In traditional planning methods, surgeons rely on physical models and two-dimensional imaging, which can be time-consuming and less accurate. Intraoral fiducial markers, for example, help align digital dental models with CT scans, creating a more accurate three-dimensional model of the patient's anatomy. This is a significant step because it eliminates the need for physical casts and model surgery, which were the mainstay of planning in the past. The digital workflow also includes clinical photography, which provides visual information about the patient's facial and dental anatomy. This information is merged with other data sources to create a comprehensive 3D model that surgeons can use to plan and visualize the surgery.
The digital transfer of occlusal data is equally important. This involves capturing the patient's bite and occlusal relationships using digital tools, which are then incorporated into the 3D model. This process is more precise than traditional methods, where occlusal relationships were simulated using stone dental models mounted on an articulator. With VSP, surgeons can perform virtual osteotomies and set the occlusion virtually, ensuring that the planned movements are accurate and align with the desired postoperative outcome.
The final step in the VSP workflow involves creating patient-specific cutting guides and plates. These tools are designed using computer-aided design and manufacturing (CAD/CAM) techniques and are fabricated based on the virtual surgical plan. By using these guides and plates, surgeons can ensure that the actual surgical intervention aligns as precisely as possible with the planned movements, reducing intraoperative inaccuracies and improving patient outcomes.
The benefits of VSP are not limited to precision and efficiency. It also provides a powerful tool for patient education and communication within the treatment team. Surgeons can use 3D models to explain the surgical plan to patients, improving understanding and reducing preoperative patient and surgeon communication errors. Furthermore, the use of VSP has been associated with reduced operative times and cost savings, as it streamlines the planning process and can decrease the time required for actual surgery.
In conclusion, virtual surgical planning has been a significant step in transforming orthognathic procedures. By integrating intraoral fiducial markers, clinical photography, and digital occlusal data into a comprehensive 3D model, surgeons can create accurate surgical plans that improve outcomes and streamline the surgical workflow. This technology not only benefits surgeons but also patients, by ensuring more precise and effective surgical corrections.
