Fixed jaw position navigation registration guide and its registration method

Abstract

The invention belongs to the technical field of cranial and maxillofacial surgery, in particular to a fixed jaw position navigation and registration guide plate and a registration method thereof, including an occlusal plate. The occlusal plate and the occlusal plate are in close contact with the mandibular teeth, and the two occlusal plates are fixedly connected by pillars. The side of the occlusal plate is provided with discretely distributed virtual registration landmark points; In the intraoral surgery of the same path, the pillar part can ensure sufficient surgical space to meet the surgical needs. The patient only needs to take an imaging examination according to the doctor's requirements during the first visit, which can avoid secondary radiation damage. The fixed jaw position navigation and registration guide plate is A novel guide plate combines computer-aided design technology, three-dimensional printing technology and navigation technology, and its corresponding registration method uses virtual design registration marker points to complete system registration, which is an innovative registration method.

Description

technical field [0001] The invention belongs to the technical field of craniomaxillofacial surgery, and in particular relates to a fixed jaw position navigation and registration guide plate and a registration method thereof. Background technique [0002] Optical navigation technology and its corresponding registration methods are very mature, and the target registration accuracy can satisfy most craniofacial surgeries. However, in the clinical work, the inventors found that a large number of cases need to be maintained in a specific jaw position, such as the maximally open jaw position and the median occlusal position, that is, it is necessary to maintain the mandible in this specific position during the operation. [0003] Because the position of the mandible changes during the operation, the position of the anatomical structure during the operation does not match the imaging data before the operation, resulting in image drift and greatly reducing the navigation accuracy. ...
