Problems solved by technology

When the patient wears a registration device to guide the real-time position of the dental handpiece to align with the CT image, it will cause the patient to open their mouth for a long time and cause the user's mouth to be tired
Moreover, when performing implant surgery, the doctor needs to look at the real-time situation in the patient's mouth while looking at the screen of the surgical navigation system, which makes it impossible to take care of both at the same time, which will lead to the problem of decreased accuracy of the operation.

Abstract

The invention discloses a surgical navigation method and device based on an AR device. The method includes the following steps of obtaining an intraoral model with at least one marking point, whereinthe intraoral model includes bone information, soft tissue information and face information; converting the intraoral model into an augmented reality (AR) image to be stored; projecting the AR image into a designated area in front of the eyes of a user to be displayed, and prompting that correction succeeds when the marking points in the AR image coincide with corresponding actual intraoral marking points of the intraoral model; tracking and aligning the AR image in real time according to the actual intraoral marking points, and conducting navigation prompting on a dental cell phone. The surgical navigation method and device based on the AR device have the advantages that checking can be conveniently conducted by users at the same time, and operation accuracy can be improved.

Description

technical field [0001] The present invention relates to the field of intraoral implantation, in particular to a surgical navigation method and device based on AR (Augmented Reality, augmented reality technology) equipment. Background technique [0002] When the doctor performs implant surgery, the dental mobile phone used is connected to the surgical navigation system, and the intraoral CT (Computed Tomography) image is displayed on the screen of the surgical navigation system. During operation, the CT image will also have corresponding action synchronization (for example, when a dental mobile phone is used to drill a hole in a patient's tooth, the intraoral CT image displayed on the screen of the surgical navigation system will also have a corresponding drill for the tooth. hole animation). When the patient wears a registration device to guide the real-time position of the dental handpiece to align with the CT image, it will cause the patient to open their mouth for a long...
