Embodiment 1
[0022] see Figure 1-3 , the present invention provides the following technical solutions: a fixed jaw position navigation registration guide plate, including an occlusal plate 1, the number of the occlusal plates 1 is two, and the two occlusal plates 1 are respectively an occlusal plate and a mandibular tooth in close contact with the maxillary teeth The occlusal plate 1 in close contact, the part of the occlusal plate 1 is used for close contact with the upper and lower jaw teeth to ensure the stability of the mandible after the patient wears the guide plate during the operation, and the two occlusal plates are fixedly connected by the pillar 2, The pillar 2 is a cylinder connected to the upper and lower jaw occlusal plate 1, and the supporting force is strong enough to avoid deformation after being worn by the patient during the operation. The side of the occlusal plate is provided with discretely distributed virtual registration marker points 3.

Abstract
The invention belongs to the technical field of craniomaxillofacial surgery, and particularly relates to a fixed mandibular position navigation registration guide plate and a registration method thereof. The fixed mandibular position navigation registration guide plate comprises two biting plates, wherein the two biting plates are respectively biting plates in tight contact with maxillary teeth and biting plates in tight contact with mandibular teeth, and the two biting plates are fixedly connected through a supporting pillar; discrete-distribution virtual registration mark points are formed on the sides of the biting plates; in accordance with the operation in the mouth cavity at specific mandibular position transoral approach, the supporting pillar parts can guarantee sufficient operation space, and can meet operation requirements; patients only need to shoot imaging inspection once according to the requirements of doctors during primary examination, and secondary radiation injury can be avoided; and the fixed mandibular position navigation registration guide plate is a novel guide plate. Through combination of a computer auxiliary design technique, a three-dimensional printing technique and a navigation technique, the corresponding registration method adopts the discrete-distribution virtual registration mark points to complete system registration, and the method 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. ...
