Computer-aided oral implantology: methods and applications.
Aiming at transferring the preoperative planning information to the patient in oral implantology, this study presents an image guided oral implant system (IGOIS), which integrates 3D medical modelling, preoperative surgical planning and intraoperative tracking into a dental navigation system. With the fabrication of a tooth-supported polymer resin template, a non-invasive point-based registration method through ICP algorithm is explicitly discussed. The experimental test shows that deviation between planned and achieved position of the implant is 1.2 mm at the tip and 1.3 mm at the head, which thereby demonstrates that IGOIS can reach a level of accuracy where further clinical developments are feasible.
