Tooth root canal orifice treatment aided navigation method and system based on mixed reality technology

The invention provides a tooth root canal orifice treatment aided navigation method and system based on a mixed reality technology, and belongs to the field of root canal therapies.The method comprises the steps that a first marker and a second marker are pre-installed on teeth of a patient respectively, and the first marker and the second marker serve as base points; identifying and marking the shape and the position of the tooth root canal orifice based on an AI deep learning algorithm and an image identification algorithm, and matching the tooth root canal orifice marking point with the coordinate position of the first marker in the world coordinate system to obtain the coordinate position of the tooth root canal orifice marking point in the projection coordinate system; and matching the coordinate position of the second marker under the projection coordinate with the coordinate position of the tooth root canal orifice mark point under the projection coordinate system to obtain the relative position of the
