Dental implant guide plate, visual guide system and registration method thereof

Abstract

The embodiment of the invention provides a dental implant guide plate, a visual guide system and a registration method thereof. The dental implant guide plate is used for being attached to a dentition, at least three through holes are formed in the dental implant guide plate in a penetrating mode, and each through hole is used for forming a registration point so that the tip of the calibration probe can make contact with a corresponding marking point on the dentition after being inserted. The embodiment of the invention provides a registration method. The dental implant guide plate is attachedto the dentition of a patient; in the registration process, a calibration probe is used for contacting and aligning to a registration point on the dental implant guide plate, and space coordinates ofregistration point in a visual sensor coordinate system can be obtained; due to the fact that the registration points on the dental implant guide plate are set in advance, a doctor does not need to find tooth feature points in an operation to serve as the registration points, so registration operation is facilitated, registration precision is improved, and finally the precision of implantation operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dental implant guide plate, a visual guidance system and a registration method thereof. Background technique [0002] In recent years, with the clinical promotion of oral implant technology and the improvement of people's requirements for oral health, more and more patients choose to have implant restoration treatment for missing teeth. The position and angle of implant placement are key goals for successful surgery, and implant guide technology and implant navigation technology are sharp tools to achieve this goal. [0003] Registration is a key step in implant navigation technology, which is to determine the relative position and posture relationship between the virtual space coordinate system and the visual coordinate system. At present, the method of marker registration is often used to realize the mapping relationship between the two spaces by establishing the map...

AI Technical Summary

Problems solved by technology

Anatomical landmarks are used for registration, the registration accuracy is low, and it depends on the doctor's operating experience; while artificial markers are used for registration, it needs to be implanted in the patient's alveolar process or jaw, which is not only cumbersome to operate , but also cause unnecessary trauma to the patient and even lead to infection
