Abstract
A mixed reality system and method for determining spatial positions of dental instruments without having a fixed intra oral reference point is disclosed. An intra-oral image sensor-based positioning device including at least two cameras is provided to sense and track the movements of dental instruments being used. The three-dimensional coordinates relating to the movement and orientation of the dental instruments are obtained for real time or delayed use in a mixed reality environment.
