Problems solved by technology

At present, the common auxiliary training devices are mainly mouth opening training devices, which have certain disadvantages: (1) weak individuation, mostly processed by traditional crafts, (2) function is limited to mouth opening movement, and there is no mandibular protraction at home and abroad Sports Aids Reporting
(3) The stability is poor, and the contact surface between the occlusal plate and the teeth is mostly flat; (4) The wearing comfort is poor
(5) Auxiliary training devices of different specifications are required for different rehabilitation stages of patients, which has high economic costs

preparation example Construction

[0089] The second aspect of the present invention provides a preparation method of a digital mandibular extension exercise auxiliary trainer, the method comprising: constructing the digitalized mandibular extension exercise auxiliary trainer model according to the first aspect of the present invention. Mandibular extension motion auxiliary training device model, preparation of digital mandibular extension motion auxiliary training device. According to the construction method of the digitized mandibular extension motion auxiliary trainer model according to the present invention, the digitalized mandibular extension motion auxiliary trainer model is constructed and the method for preparing the digital mandibular extension motion auxiliary trainer should be for those skilled in the art. It is known that, for example, a 3D printing method can be used, and the material used can be nano-resin and the like.

[0090] The third aspect of the present invention provides a digital mandibu...

Embodiment 1

[0109] 1) For patients whose mouth opening is less than 2cm before operation, CT scan can be performed before operation, with a slice thickness of 0.625mm, to collect occlusal information;

[0110] 2) Input the collected occlusal information into the computer in Dicom format, and transmit it to the analysis and processing terminal, which performs information integration and 3D reconstruction through SurgiCase CMF5.0 software.

[0111] 3) At the same time, the designer designed the digital occlusal plate auxiliary training device needed for the patient's postoperative mandibular movement training process. The specific parameters are as follows: the width of the occlusal part of the maxillary teeth is 7-12mm, and the height is 3mm. The width of the occlusal part of the mandibular teeth is 7-12 mm, and the height is 3 mm. The diameter of the screw accommodation cavity is 7mm. The length of the screw is 27mm. The diameter of the stopper is 8mm. The data is transmitted to the co...

Embodiment 2

[0115] 1) For patients whose mouth opening exceeds 2cm before surgery, a dental model can be taken directly, and the model can be scanned to obtain occlusal relationship data, or the patient's mouth can be directly scanned with a mouth scanner to obtain occlusal relationship data;

[0116] 2) Input the collected occlusal information into the computer in Dicom format, and transmit it to the analysis and processing terminal, which performs information integration and 3D reconstruction through SurgiCase CMF5.0 software.

[0117] 3) At the same time, the designer designed the digital occlusal plate auxiliary training device needed for the patient's postoperative mandibular movement training process. The specific parameters are as follows: the width of the occlusal part of the maxillary teeth is 7-15mm, and the height is 5mm. The width of the occlusal part of the mandibular teeth is 7-15 mm, and the height is 5 mm. The diameter of the screw accommodation cavity is 7 mm. The length o...

Abstract

The invention relates to the field of medical instruments, in particular to a digitized mandibular protraction auxiliary training device and a construction method thereof. The auxiliary training device comprises an upper jaw tooth occlusion in-position part and a lower jaw tooth occlusion in-position part, and a retention assembly is arranged between the upper jaw tooth occlusion in-position part and the lower jaw tooth occlusion in-position part; a first groove body is formed in the side, away from the upper jaw teeth, of the upper jaw tooth occlusion in-place part, a second groove body is formed in the side, away from the lower jaw teeth, of the lower jaw tooth occlusion in-place part, and a screw containing cavity is defined by the first groove body and the second groove body; the tongue side of the first groove body extends to be provided with a tongue side protruding buckle; an internal thread is arranged in the second groove body; a screw rod is arranged in the screw containing cavity, a tongue side limiting piece and a lip side limiting piece are arranged at the two ends of the screw rod respectively, and external threads are arranged on the screw rod. According to the application, a upper tooth socket of the upper jaw tooth occlusion in-position part and a lower tooth socket of the lower jaw tooth occlusion in-position part can be worn on the upper and lower teeth of a patient, and the lower biteplate can stretch forwards and retreat by rotating the lip side limiting piece.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a digital mandibular extension motion auxiliary training device and a construction method thereof. Background technique [0002] After oral and maxillofacial surgery, due to bone tissue adhesion and soft tissue contracture, patients often have limited mouth opening and jaw movement. Postoperative rehabilitation training helps bone tissue and masticatory muscles adapt to the new range of activity, promotes tissue healing, strengthens masticatory muscle strength, and improves patients' language and eating functions. It plays an important and active role in postoperative rehabilitation, mainly including mouth opening training. , Mandibular extension and lateral movement training, according to different stages of postoperative use of different training programs. At present, the common auxiliary training devices are mainly mouth opening training devices, which have certain disadvanta...
