Marker for image information registration

Abstract

Disclosed is a marker for image information registration. The marker for image information registration according to one embodiment of the present invention is provided inside an oral cavity of the person to be operated on and provides a reference point for obtaining image information associated with the oral tissue of the person to be operated on.

Description

technical field [0001] The present invention relates to a marker, in particular to a marker for integrating image information, which synchronizes the following information, thereby making it easy to make a surgical guide: image information of intraoral tissues of the surgical object data, and the image information data included in the model that replicates the intraoral tissue of the surgical object, or the coordinate relationship between the processing instrument placed on the model that replicates the intraoral tissue, and the above-mentioned surgical guide accurately guides the intraoral surgery. Background technique [0002] In general, in the field of dental surgery, image technology is used both in diagnosis and surgical planning, and importantly in the field of surgical guidance. The image technology described above is used in various fields, including: shape design of dentures, fabrication of surgical guides for implant surgery, jaw plasticity required for relative m...

AI Technical Summary

Problems solved by technology

Image information about teeth (including dentures) or gums can be obtained in the image information of the replica inside the oral cavity, and the shape of the alveolar bone or teeth (including dentures) is mainly obtained in the anatomical image information inside the oral cavity, but when the teeth are formed into When there is a lot of image noise due to metal dentures, or when the accuracy of the image is reduced according to the tooth shape, or in the case of patients without teeth, it is not easy to use common elements for integration

In addition, when specifying the gingiva using an integrated common element, it causes a troublesome problem that the surface information about the gingiva is not easily acquired from anatomical image information like CT, and in order to acquire, air is blown in the oral cavity, or Contains a radiographic construct, or acquires image information with an additional surgical guide for incision of soft tissue placed, or coats or adapts a radiographic construct to the interior of the oral cavity

[0012] In order to integrate information and synchronous coordinates required in the process of making a surgical guide for guiding implant surgery, a surgical guide in the form of thermoplastic resin that covers the gums and teeth is used, but it will cause the following problems: The surface of the guide plate is embedded with a radiopaque material through more than one perforation, and then it is applied to the oral cavity of the surgical object and CT scans are performed, and the preparation process and time required before CT scans increase

[0013] In addition, in the case of markers that are simply covered in the oral cavity of the subject to be operated or occluded and fixed between the upper and lower occlusal surfaces, there are problems that the repeatability of the position placed in the oral cavity is significantly reduced or the fixation site is fragile. Cannot achieve firm fixation
