Embodiment Construction

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

[0022] A method of multi-source data fusion and mandibular trajectory adjustment to determine the jaw position of the present invention has the following steps:

[0023] Perform multi-source data fusion; adjust the trajectory of the mandible to determine the relationship between the jaws.

[0024] in,

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

[0026] S1. Establish a digital dentition model: clinical impressions, occlusal occlusal records of cusps, pouring models, dental model 3D scanner scans the upper and lower dentition models, and the buccal position of the upper and lower dentition models when the cusps are staggered relationship, registration and reconstruction of upper and lower jaw digital dentition models;

Abstract

The invention relates to a method for determining jaw positions through multi-source data fusion and mandible movement track adjustment. The method comprises the following steps: performing multi-source data fusion, and adjusting the mandible movement track to determine the jaw position relationship. The digital determination of the jaw position relationship of the condyle displacement patient isrealized by using a data fusion and mandible motion trail adjustment method, the occlusion reconstruction patient jaw position relationship of the condyle displacement is controllably, directly and objectively determined, and therefore, the seamless connection of the jaw position relationship determination and the digital design of the prosthesis is realized. A digital solution is provided for complex jaw position determination and transfer in clinic.

Description

technical field [0001] The invention relates to the fields of stomatology restoration and temporomandibular joint, in particular to a method for multi-source data fusion and mandibular motion trajectory adjustment to determine jaw position. Background technique [0002] Determination of the jaw position for occlusal reconstruction is a key step that affects the success of the treatment. Patients undergoing occlusal reconstruction sometimes have structural disturbances of the temporomandibular joint, such as decreased occlusal vertical distance and mandibular setback status due to severe wear of the dentition, accompanied by changes in the temporomandibular joint space. For the purpose of restoring the dentition and restoring the masticatory function, it is necessary to increase the vertical distance and properly guide the mandible forward to determine a more normal overbite coverage relationship, and then transfer the new jaw position to the articulator for repositioning the...
