Embodiment 1

[0034] First, take a pair of standard upper and lower jaw dentition models, and record the occlusal relationship, and put the model into the upper jaw frame. For patients with irregular dentition, alginate impression materials can be used to accurately obtain dental impressions and perfusion models. Adjust the opening of the jaw frame to within the range of one to three fingers, and carve the wax shape of the mouth opener in the anterior teeth area, making it into a figure 1 and figure 2 Resin mouth opener in the anterior region shown. Then use Siemens NX 10.0 software to measure figure 1 and figure 2 The size of the anterior tooth resin mouth opener, and then use Siemens NX 10.0 software to design and modify it, remove the undercut of the anterior dentition, eliminate tooth marks, and appropriately expand and smooth the size of the anterior tooth area, so as to design image 3 Universal anterior mouth opener shown.

[0035] In this study, a general-purpose anterior mou...

Abstract

The invention relates to a preparation method of a universal mouth gag for anterior teeth. The method comprises the steps of (1) taking a pair of standard upper and lower jaw dentition models, recording an occlusion relationship, and then installing the models on a jaw frame; (2) adjusting the opening degree of the jaw frame, forming a wax shape of a mouth gag body for an anterior tooth region bymeans of engraving, and manufacturing the mouth gag body by means of resin for the anterior tooth region; (3) measuring the size and designing the resin mouth gag body for the anterior tooth region, and obtaining data of the universal mouth gag for the anterior teeth; (4) converting the data of the designed universal mouth gag for the anterior teeth into data recognized by a 3D printer, and printing the universal mouth gag for the anterior teeth. The preparation method is simple and easy to implement and low in cost, and batched manufacturing can be achieved by adopting a 3D printing technology; the obtained universal mouth gag for the anterior teeth can effectively reduce the frequency of seeing a doctor and shorten the time for seeing the doctor for a patient, can be used as a radiotherapy stent in oral and maxillofacial radiotherapy and an oral fixation device during intraoral surgery, and has a great application prospect 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...
