Evaluation of the accuracy of the office-based virtual surgical planning for Orthognathic and Implant surgery

Orthognathic surgery is a procedure used to correct facial deformities and is a mainstay treatment in the oral
and maxillofacial surgery field. Another common procedure in the field of oral and maxillofacial surgery is dental
implant surgery that is used to replace missing teeth. Currently, dental implants are one of the most preferred
treatment options for recreating tooth form and function.
The surgical procedure is complex and requires extensive planning and accuracy to obtain a successful
outcome. For this reason, computer-aided 3D virtual surgical planning has been adopted to improve the
efficiency and accuracy of the procedure. This is most commonly done through a third party company who uses
software to manipulate the data as per the surgeons’ operative plan, which requires significant resource and
time as well as high cost for patients. The purpose of this study is to establish a workflow for an office-based
approach to virtually plan orthognathic and implant surgeries that can be implemented at the surgical facilities.
The proposal develops the methods for evaluation of the accuracy of the office-based virtual surgical planning
for Orthognathic and Implant surgery and helps to better assess the plausibility of the new workflow.
