4 results about "Masticatory muscle" patented technology

The masticatory muscles are used in chewing. They include the jaw muscles and the muscles of the temples. Therefore, masticatory muscle myositis is inflammation of the muscles in the jaw and temple. It affects the trigeminal nerve and can lead to atrophy of the muscles and dogs may have a dropped jaw that cannot stay closed.

Intelligent reconstruction method for missing tooth morphology based on contralateral tooth mirror transformation

The present application relates to the technical field of image data processing, in particular to a missing tooth shape intelligent reconstruction method based on contralateral tooth mirror image transformation. According to the patient's masseter axial ultrasound image and temporal muscle axial ultrasound image, the robustness of each side of the masticatory muscle of the patient's both cheeks is determined; the average wear degree of each side of the patient's both cheeks is measured, and then a regression equation of the average wear degree and the robustness is constructed; the coordination coefficient between the missing tooth side and the contralateral side of the patient is determined by using the regression equation, and then it is judged whether the contralateral homonym tooth of the missing tooth needs to be corrected; if correction is needed, the wear degree correction coefficient of the contralateral homonym tooth is constructed, and then the contralateral homonym tooth of the missing tooth is corrected, and the missing tooth shape reconstruction is carried out based on the corrected contralateral homonym tooth. The present application corrects the contralateral homonym tooth of the missing tooth, so that the missing tooth shape reconstruction is more consistent with the dynamic coordination of masticatory movement.

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.

Method, system and equipment for manufacturing and testing double-jaw digital biteplate and medium

ActiveCN121796107ADetails involving processing stepsImpression capsDynamic motionImage processing software
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.
