The invention relates to the technical field of image data processing, in particular to a missing tooth form intelligent reconstruction method based on contralateral tooth mirror image transformation. According to a masseter axial ultrasonic image and a temporomuscle axial ultrasonic image of a patient, the robustness degree of masticatory muscles on each side of double cheeks of the patient is determined; the method comprises the following steps: measuring the average wear degree of each side of double cheeks of a patient, and then constructing a regression equation of the average wear degree and the robustness degree; determining a coordination coefficient between an edentulous side and an opposite side of the patient by utilizing the regression equation, and further judging whether the homonymous teeth on the opposite side of the edentulous side need to be corrected or not; and if correction is needed, constructing a wear degree correction coefficient of the opposite-side homonymous teeth, further correcting the opposite-side homonymous teeth of the missing teeth, and performing missing tooth form reconstruction based on the corrected opposite-side homonymous teeth. According to the method, the same-name teeth on the opposite side of the missing teeth are corrected, so that the form reconstruction of the missing teeth better conforms to the dynamic coordination of chewing movement.

The utility model provides a post-radiotherapy oral occlusion exerciser for a head and neck tumor patient. The post-radiotherapy oral occlusion exerciser comprises a body and a fixing belt, the body is a trapezoid table and comprises a first face and a second face, the first face faces the inner side of an oral cavity, the area of the first face is smaller than that of the second face, protruding edges are symmetrically arranged on an upper inclined face and a lower inclined face which are opposite to each other of the body, fixing belts are fixed to the inclined faces on the two sides of the body respectively, and an elastic ball is arranged in the body. According to the distance of the mouth-opening exerciser placed in the oral cavity, mouth-opening exercises can be performed step by step, progressive exercises are realized, and the purpose of mouth-opening exercises is achieved by ensuring that each step is prevented from slipping and teeth are limited during occlusion through the arranged convex edges. Through the elasticity of the bouncy ball, masticatory muscle groups of the jaw are exercised during occlusion exercise, and muscle recovery is promoted. The fixing band of the body is convenient for fixing the body during use, the two hands are liberated, the hand fatigue caused by hand holding is avoided, the length of the fixing band can be adjusted, and the device is suitable for patients with different head circumferences and patients.

The invention discloses a manufacturing and testing method, system and equipment of a double-jaw digital biteplate and a medium. Preoperative masticatory muscle depolarization preprocessing is conducted on a patient, and temporomandibular joint soft and hard tissue three-dimensional data, face proportion data, dentition form data and mandibular dynamic movement track data of the patient are obtained; inputting the soft and hard tissue data into medical image processing software, correcting a condylar process position and virtually positioning the condylar process position to a central position or a muscle-bone stable position of a glenoid fossa in combination with a dentition overlay coverage condition, and obtaining corrected data; by taking the corrected condylar process position as a jaw position reference, the face proportion as a height constraint and the dynamic trajectory as a motion simulation basis, carrying out cooperative processing to generate a three-dimensional model of the biteplate; and manufacturing an entity according to the model, carrying out myoelectricity and occlusion pressure test on the wearer, judging the suitability, and feeding back to adjust the model and remanufacturing the test if the model is abnormal. The personalized adaptation precision, functionality and treatment reliability of the biteplate are improved.

The invention discloses a masticatory muscle recovery training appliance, and relates to the technical field of masticatory muscle training, the masticatory muscle recovery training appliance comprises a support frame, the outer surface of the support frame is provided with a masticatory training assembly for training masticatory muscles of a gout patient, the masticatory training assembly comprises a limiting frame, and the outer surface of the masticatory training assembly is provided with a saliva absorption assembly. According to the masticatory muscle recovery training tool, when a large amount of hydrops appears in the oral cavity in the process that a moderate wind patient uses the masticatory muscle training device, the two occlusal pads are moved forwards into the oral cavity of the patient and between upper and lower incisor teeth, so that the oral cavity of the patient is supported, and then the suction catheter is inserted into the oral cavity of the patient; waste liquid is absorbed through driving of the negative pressure pump, meanwhile, saliva in the oral cavity of the patient is comprehensively absorbed by rotating the suction catheter, and the problem that in the prior art, due to the fact that the stroke patient swallow too slowly and weakly, the patient feels uncomfortable and cannot concentrate on masticatory muscle power generation control, and training efficiency is reduced is solved.
