At present, most clinical operations are that a doctor firstly determines the vertical occlusion distance for a patient according to certain experience, and then guides the patient to move a mandibular condyle to a most anterior most stable position of a temporomandibular joint fossa in a swallowing occlusion way to determine a median relation position. However, such procedures are highly dependent on experience and are only suitable for experienced physicians.
In order to improve the accuracy and objectivity of determining the center relation position, a description method of the trace of the movement of the lower jaw outside or inside the mouth, namely a gothic arch description method, is adopted at present, generally, a maxillary clamping plate is fixedly arranged on an upper jaw occlusal dike, a mandibular clamping plate is fixedly arranged on a mandibular occlusal dike, and the movement trace of the lower jaw during the protrusion and lateral movement in the horizontal plane is described as the gothic arch by the maxillary clamping plate and the mandibular clamping plate. The top point of the gothic arch is formed by the intersection of a plurality of trajectory lines, the intersection point is the only position of the mandible retreating, and when the mandible clamping plate is positioned at the intersection point, the recorded jaw position is the median relation position.
However, the fixing structure of the current goter type bow tracing device is relatively simple, if the wax occlusal dikes are used for fixing components such as the mandible clamping plate and the maxilla clamping plate, the components are easy to loosen, shift and even fall off in the mandible movement, which leads to inaccurate tracing, and if the occlusal dikes made of light-cured resin are used for fixing the components, the resin is needed to be ground during final disassembly, which is troublesome in operation.
