Embodiment Construction

[0021] The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0022] A method for determining jaw position by multi-source data fusion and mandibular movement trajectory adjustment according to the present invention has the following steps:

[0023] Perform multi-source data fusion; adjust the mandibular movement trajectory to determine the relationship of the jaw position.

[0024] in,

[0025] The performing multi-source data fusion includes the following steps:

[0026] S1. Establish a digital dentition model: take clinical impressions, record the occlusal occlusion, make a model, scan the upper and lower dentition models with a three-dimensional scanner of the dental model, and scan the buccal position of the upper and lower dentition models when the cusps are staggered. relationship, registration and reconstruction of the digital dentition model of the upper and lower jaws;

[0027] S2. Three-dime...

Abstract

The invention relates to a method for multi-source data fusion and mandibular movement trajectory adjustment to determine the jaw position, comprising the following steps: performing multi-source data fusion; adjusting the mandibular movement trajectory, and determining the jaw position relationship. The present invention realizes the digital determination of the jaw position relationship of patients with condyle displacement by means of data fusion and mandibular motion trajectory adjustment, and can controllably, directly and objectively determine the jaw position relationship of patients with occlusal reconstruction of condyle displacement and realize the jaw position The seamless connection between relationship determination and restoration digital design provides a digital solution for complex jaw position determination and transfer in clinical practice.

Description

technical field [0001] The invention relates to the fields of stomatology restoration and temporomandibular joints, and in particular relates to a method for determining jaw position by fusion of multi-source data and adjustment of mandibular movement trajectory. Background technique [0002] The determination of the jaw position of occlusal reconstruction is a key step that affects the success of the treatment. Patients undergoing occlusal reconstruction therapy sometimes have TMJ structural disturbances, such as reduced vertical occlusal distance and mandibular receding due to severe dentition wear, with changes in the TMJ space. For the purpose of restoring the dentition and restoring the masticatory function, it is necessary to raise the vertical distance, guide the mandible forward appropriately, determine a more normal overbite covering relationship, and then transfer the new jaw position to the articulator for repositioning the teeth. Pad making. The clinical maxill...
