Abstract

The invention relates to a measuring device for condyle guide inclination, comprising a transmitter, a receiver, a processor, a first measuring fixture and a second measuring fixture; the transmitter is used for transmitting electromagnetic signals for measuring the position of the condyle; the receiver is used for measuring the position of the condyle. The position information is obtained by solving; the first measuring fixture is used to clamp the receiver, providing a measurement reference point to realize the static position measurement of the left and right condyles; the second measuring fixture is used to clamp the receiver to the follow-up of the mandibular movement to measure the static position of the follow-up point and the dynamic pose data when the receiver moves with the mandible; the processor is used to calculate the position difference between the left and right condyles and the follow-up point; according to the measured dynamic pose data Combined with the position difference data, the dynamic trajectories of the left and right condyles are calculated, and then the condyle guide slope is calculated. The condyle guide inclination calculated by the invention has strong practical application value, and significantly improves the possibility of applying the electromagnetic facebow to the market.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a measuring device for the inclination of a condyle. Background technique [0002] In the field of prosthodontics, on the model Frame is an indispensable step in the diagnosis and treatment process, through The simulation of the frame can ensure the coordination of form and function after the restoration made on the plaster model is brought into the mouth as much as possible. while using In order to obtain the simulation results with as little error as possible in the actual movement of the patient’s oromandibular system, the positional relationship between the maxillary dentition and the mandibular joint can be recorded through facebow transfer. [0003] In the process of using the facebow, in order to obtain the condyle guide slope, the patient needs to perform various movements of the mandible to obtain the movement trajectory of the condyle. For t...
