Assisted Guidance and Navigation Method in Intraoral Surgery

An assisted guidance and navigation method in intraoral surgeries, which is a method using computerized tomography (CT) photography and an optical positioning system to track medical appliances, the method at least comprising:

• (A) providing an optical positioning treatment instrument and an optical positioning device at an intraoral tissue receiving treatment;
• (B) obtaining image data of the intraoral tissue receiving treatment through CT photography, obtaining a positioning relationship between the treatment instrument and the optical positioning device, making the image data and physical space generate correspondence through an algorithm, and then combining actions of the treatment instrument with the image data precisely;
• and
• (C) real-time checking the image data and assisting guidance and navigation to perform a surgery on the intraoral tissue through movement of the treatment instrument at teeth receiving treatment.
