Problems solved by technology

The accuracy of registration using anatomical landmarks is low and depends on the doctor's operating experience, while using artificial landmarks for registration usually needs to be implanted in the patient's alveolar process or jawbone, which will cause unnecessary trauma to the patient even lead to infection

Abstract

The embodiment of the invention provides a registration method and system for a dental navigation operation. The registration method comprises the following steps of: setting artificial mark points onthe jaw of a patient in a noninvasive manner; clicking the artificial mark points set on the jaw of the patient by utilizing a probe of a visual navigation instrument or a drill bit of an implantingmobile phone according to the special structures of the artificial mark points; determining the coordinates of the tips of grooves in the artificial mark points in a coordinate system of the visual navigation instrument, and determining the coordinates of the tips of the grooves in the artificial mark points in a CT image space coordinate system; registering the corresponding relation of the two coordinate systems according to the coordinates of the tips of the grooves in the artificial mark points in the two coordinate systems; and finally obtaining the mapping relation between a virtual space coordinate system and the coordinate system of the visual navigation instrument, thereby finishing the registration of the dental implanting navigation operation.

Description

technical field [0001] The invention relates to the technical field of oral medicine, in particular to a registration method and system for dental navigation surgery. Background technique [0002] Many factors in daily life can lead to tooth loss. Compared with fixed dentures and removable dentures, dental implants have gradually become a common method of tooth loss restoration. The accuracy of the position and angle of implant placement is a key factor affecting the success of dental implant surgery. [0003] Registration is a key step in oral implant navigation surgery, which is to determine the relative position and posture relationship between the virtual space coordinate system and the visual navigation instrument coordinate system. At present, the method of marker registration is often used to realize the mapping relationship between the two spaces by establishing the mapping relationship between the marker points on the medical image and the corresponding marker poin...
