3D printing mandible impacted wisdom tooth extraction training model

Abstract

The invention discloses a 3D printing mandible impacted wisdom tooth extraction training model which is characterized by comprising a mandible bone, an impacted wisdom tooth growth section, impacted wisdom teeth, mandible second molars, inferior alveolar nerve blood vessel bundles, alveolar bones and normal teeth. The mandibular impacted wisdom tooth extraction training model can be manufactured through 3D customization printing, a typical case is selected for 3D printing to obtain the training model, the training model is detachable in the impacted wisdom tooth generation section, the growth and position conditions of the impacted wisdom teeth exist in the training model, and a nerve structure is printed and designed in the mandible; an operator can extract the impacted wisdom teeth of the lower jaw more truly through the training model, and can master extraction skills more quickly.

Description

technical field [0001] The invention belongs to the field of oral medical auxiliary devices, in particular to a 3D printed mandibular impacted wisdom tooth extraction training model. Background technique [0002] Mandibular impacted wisdom teeth mean that there is no extra space between the second molar and the mandibular ramus, resulting in no way for the wisdom teeth to erupt, so that they are completely embedded in the body of the mandible or the mandibular ramus, and finally form the mandibular impacted wisdom teeth; [0003] There are three main classification methods for mandibular impacted wisdom teeth: the first type is based on the relationship between wisdom teeth and mandibular second molars and mandibular ramus; the first type is that there is enough space between second molars and mandibular ramus to accommodate Wisdom teeth, and then wisdom teeth can erupt completely. The second type is that the gap between the second molar and the mandibular ramus is not large...

AI Technical Summary

Problems solved by technology

[0004] Mandibular impacted wisdom teeth generally cause pericoronitis of wisdom teeth, and then lead to serious complications such as space infection, causing facial pain and limited mouth opening of the patient; if not treated in time, it will bring great pain to the patient; The most common way to deal with mandibular impacted wisdom teeth is extraction; due to the special position of mandibular impacted wisdom teeth, there are nerves and accompanying inferior alveolar blood vessels around them, so extraction is more difficult than other teeth. If the operation technique is not skilled, Peripheral nerves may be damaged during the operation, the wound is too large or bleeding may be caused; for doctors who have no experience in stomatology, the extraction of impacted wisdom teeth requires a lot of practice before they can master the skills. There are several problems in the extraction operation training model of extraction: 1. The structure of the model is single, only the most basic mandible and tooth structure, and the operator can only give theoretical explanations on the simple model; 2. There is no way to observe The direction of the internal dental nerve helps it to grasp the cutting depth and axial direction when the turbine is used to separate the teeth, so as to avoid the dental nerve; 3. Without the structural design of the impacted wisdom teeth, the operator cannot judge when the impacted wisdom teeth have not erupted or erupted a little Its internal growth; 4. The model structure is based on the same theoretical design, and it is impossible to carry out targeted design according to the actual situation. Due to the different growth positions and growth conditions of individual impacted wisdom teeth, the operator needs to judge and master different impacted wisdom teeth The growth and location of the game can accumulate experience
