Problems solved by technology

The existing aligners and splints have the following defects: 1. The production process is cumbersome, requiring multiple processes, which is time-consuming and labor-intensive; 2. The materials are hard materials, and the wearing comfort is not good; 3. It is not easy to clean and wears for a long time. Oral hygiene has a great impact; 4. With metal accessories, it affects the appearance; 5. It is not light enough, which affects the daily language function of patients; 6. The force is borne by individual teeth, and the shape of the dentition will change after long-term wearing

preparation example Construction

[0039] The second aspect of the present invention provides a method for preparing a self-fixating individualized mandibular retainer, the method comprising: constructing the self-fixed individualized mandibular retainer model according to the first aspect of the present invention. Fixed individualized mandibular retainer model, prepared from fixed individualized mandibular retainer. The self-fixating individualized mandibular retainer model constructed according to the construction method of the self-fixating individualized mandibular retainer model of the present invention The method for preparing the self-fixating individualized mandibular retainer should be simple for those skilled in the art It is known that, for example, oral occlusal relationship data can be obtained through CT scanning and oral scanner scanning, and can be obtained through computer digital modeling combined with 3D printing. The material used can be transparent elastic resin and the like.

[0040] The t...

Embodiment 1

[0060] 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;

[0061] 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.

[0062] 3) Simultaneously, the designer designs the patient's maxillary braces and the occlusal plate required for postoperative mandibular position adjustment. The specific parameters are as follows: the wall thickness of the maxillary braces retention area is 0.6-0.8mm, width 5-12mm, height 5-8mm. The wall thickness of the mandibular occlusal plate area is 2-4 mm, the width is 10-15 mm, and the height is 2 mm. The width of the occlusal junction zone is 10-15 mm, and the height is 1-2 mm. The data is transmitted to the computer output printing termina...

Embodiment 2

[0066] 1) For patients whose mouth opening exceeds 2cm before surgery, the dental model can be taken directly, and the occlusal relationship data can be obtained by scanning the model;

[0067] 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.

[0068] 3) At the same time, the designer designs the self-fixating individualized mandibular retainer required for the patient's postoperative mandibular movement training process. The specific parameters are as follows: the wall thickness of the maxillary tooth sleeve retention area is 0.6-0.8mm, and the width is 5-12mm , the height is 5-10mm. The wall thickness of the mandibular occlusal plate area is 2-4mm, the width is 10-15mm, and the height is 3mm. The width of the occlusal junction zone is 10-15 mm, and the height is 1-2 mm. The data is transmitted...

Abstract

The invention relates to the field of medical instruments, in particular to a self-fixing individualized mandible retainer and a construction method thereof. The construction method comprises the following steps: constructing a jaw bone three-dimensional fusion model based on a jaw bone three-dimensional model, a maxillary tooth three-dimensional model and a mandibular tooth three-dimensional model; based on the outer surface of the maxillary dentition, constructing and obtaining a maxillary tooth sleeve retention area, and forming a maxillary tooth retention groove corresponding to the mandibular dentition in the maxillary tooth sleeve retention area; on the basis of the outer surface of the mandibular dentition, constructing a mandibular tooth biteplate area, and forming a mandibular tooth containing groove corresponding to the mandibular dentition in the bottom of the mandibular tooth biteplate area; and constructing an occlusion connection area, wherein the occlusion connection area is connected with the maxillary tooth sleeve retention area and the mandibular tooth occlusion plate area. A user wears the mandible retainer to fix the mandible at a proper position of the mandible designed by a computer by means of the maxillary tooth sleeve and the biteplate, and the proper position of the mandible is adjusted according to the design of different rehabilitation stages of the user, so that the effect of preventing the mandible from retreating after an operation can be achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a self-fixing individualized mandibular retainer and a construction method thereof. Background technique [0002] Patients with temporomandibular joint disc displacement undergo temporomandibular joint disc reduction, in order to establish a good occlusal relationship, the patient's mandibular position needs to be adjusted to the ideal treatment position. However, the new occlusal relationship needs to be adjusted continuously with the neuromuscular to achieve the final stability. Therefore, patients need to wear a retainer after surgery to stabilize the mandible in an appropriate position to improve the patient's occlusal relationship. [0003] At present, mandibular leading functional appliances, repositioning splints / protrusion reduction splints, and Herbst appliances are commonly used to adjust the mandibular position. The existing aligners and splints have the following defe...
