A kind of preparation method of universal anterior teeth mouth opener

Abstract

The invention relates to a preparation method of a general-purpose anterior tooth opener, comprising: (1) taking a pair of standard upper and lower jaw dentition models, and recording the occlusal relationship, and then placing the upper jaw on the model; step (2) adjusting the jaw Opening degree, engrave the wax shape of the anterior tooth area mouth opener, and make the anterior tooth area resin mouth opener; step (3) measure and design the size of the anterior tooth area resin mouth opener, and obtain the data of the universal anterior tooth area opener; step (4) Convert the data of the designed universal anterior teeth mouth stretcher into data recognized by a 3D printer, and print out the universal anterior teeth mouth stretcher. The preparation method of the present invention is simple and easy, and the cost is low, and can be produced in batches by using 3D printing technology; the obtained universal anterior mouth opener can effectively shorten the number and time of patient visits, and can be used as a radiotherapy support for oral and maxillofacial radiotherapy As well as an oral fixation device during intraoral surgery, it has great application prospects in the medical field.

Description

technical field [0001] The invention belongs to the field of preparation of mouth openers, and in particular relates to a preparation method of a general-purpose anterior tooth opener. Background technique [0002] At present, patients with oral maxillofacial-head and neck tumors often experience severe lip and oral mucositis during radiotherapy. In addition to the impact of the total dose of treatment, the adverse effects of traditional oral radiotherapy stents cannot be ignored. Traditional oral radiotherapy stents are made of red and white proofing paste, polymer materials (such as polylactic acid), etc. The radiotherapy stents made of these materials are relatively large in size, and after being worn in the oral cavity, they are closely attached to the inner wall of the oral cavity. During treatment, the surface of the stent material will produce scattered rays, which can easily cause radiation oral mucositis, especially in the closely contacted lips. In addition, in so...
