The implementation of an integrated computer-aided system for dental implantology

This paper presents an implementation of different functionalities on a computer-aided system for dental implantology. The integrated system consists of two subsystems corresponding to two main stages of dental implantology respectively. In the preoperative planning subsystem, we provide different kinds of views based on CT data scanned from a specific patient for the dentist. And the dentist can plan implant path according to these views. The intra-operative navigational subsystem uses an infra-red light based navigation camera to locate the precise position of the surgical instrument. At last, an improved experiment on a phantom model studied the error and accuracy, to demonstrate its feasibility on further clinical trial.
