Embodiment Construction

[0027] The specific embodiments of the present invention have been described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, equivalent changes and modifications made without departing from the spirit and scope of the present invention shall fall within the scope of the present invention.

[0028] The method of positioning the temporomandibular joint based on CBCT, such as figure 1 shown, including the following steps:

[0029] (1) Capture images

[0030] The temporomandibular joint is scanned twice based on the CBCT equipment. The first scan obtains the CBCT image V1 including the entire dentition and the temporomandibular joint when the mouth is opened; the second scan narrows the beam limiter window and uses the laser light posi...

Abstract

The invention discloses a method for positioning temporomandibular joints based on CBCT. The method comprises the following steps of (1) performing image acquisition; (2) performing image fusion; and(3) performing parameter calculation. The opening and closing images of the temporomandibular joints are fused based on CBCT three-dimensional data, and displacement information of condyles at the temporomandibular joints and angle information of the opening and closing condyles and the horizontal line for diagnosis of doctors are obtained. The opening and closing movement track of a patient is obtained through secondary CBCT irradiation, the rotation center of the condyle process and the condyle guide inclination are determined, and therefore, precise positioning of the temporomandibular joints is achieved.

Description

technical field [0001] The invention relates to a positioning method, in particular to a method for positioning temporomandibular joints based on CBCT. Background technique [0002] Temporomandibular joint position is the key to correct occlusion reconstruction and orthodontic treatment. The current conventional clinical method takes the patient's dental model, uses the facebow and the fork to transfer the position of the maxillary dentition relative to the craniofacial frame to the frame, and reflects the position of the patient's temporomandibular joint through the mechanical joint structure of the frame. Simulate the jaw situation of the teeth in the oral cavity. [0003] However, the method of closing the frame is cumbersome to operate, and the fully adjustable frame is expensive, and it is impossible to ensure that every patient can be put on the frame in time, and it is very inconvenient to transmit the patient's occlusal information through the frame and the processi...
