Description

Lower jaw wisdom tooth extraction simulation training ware

Technical Field

The invention relates to a tooth extraction simulation trainer, in particular to a lower jaw wisdom tooth extraction simulation trainer.

Background

The extraction of the impacted tooth is a common diagnosis and treatment subject related to bone and soft tissue trauma in the clinical practice of alveolar surgery and has obvious postoperative reaction. Some impacted teeth may also be completely embedded by bone tissue due to the malposition of the impacted tooth, which is blocked by adjacent teeth. Therefore, the extraction of the impacted tooth is more difficult than that of other teeth, the gum covered by the gum needs to be cut, the bone embedded by the bone needs to be removed, and the dental crown blocked by the adjacent tooth needs to be split and extracted in a split mode. Therefore, the time for extracting the impacted tooth is long, and the postoperative complications are more, such as bleeding, broken root, adjacent tooth injury, postoperative lower lip numbness, dry socket disease and the like. Improper treatment can negatively affect the life quality of patients and cause psychological secondary trauma to patients.

Therefore, the oral cavity tooth extraction practice model is needed for teaching or practice, but in the existing model structure, the problem of complex model structure exists, and gingiva, teeth and alveolus are connected together by bonding mutually independent structures, so that the combination of the three is not tight, and the simulation effect is poor.

Disclosure of Invention

The invention aims to: to the problem that the simulation effect of tooth extraction operation is poor due to the fact that gingiva, teeth and tooth sockets of a tooth extraction model are connected in an adhesion mode in the prior art, the lower jaw wisdom tooth extraction simulation trainer with the integrally formed back tooth inserter is provided.

In order to achieve the above purpose, the invention provides the following technical scheme:

a lower jaw wisdom tooth extraction simulation trainer comprises a model base and a rear dental insert connected with the model base in an inserting mode, wherein the rear dental insert comprises a simulated bone structure positioned inside, simulated teeth are arranged on the upper portion of the simulated bone structure, and simulated gingiva covers outside the simulated bone structure; the back dental insert is formed by 3D printing, and the simulation bone structure, the simulation tooth and the simulation gum are integrally formed.

By adopting the technical scheme, the back dental insert consists of three structures of a simulated bone structure, a simulated tooth and a simulated gum, fully simulates the internal structure of the tooth, and forms a more vivid tooth extraction environment which can be practiced, so that the model has high simulation degree and good simulation operation effect; in addition, because simulation bone structure, simulation tooth, simulation gum three integrated into one piece, and back dental insert is printed by 3D and is formed for the connection effect of simulation bone structure, simulation tooth, simulation gum is good, does not need additionally to use binder etc. to bond between the three, makes the inside combination of whole back dental insert inseparable, and the simulation effect is good.

Furthermore, the posterior tooth insert is connected with the model base in a horizontal inserting mode. The back dental insert is connected in a splicing mode in the horizontal direction, a certain included angle exists between the back dental insert and the stress direction of the back dental insert during tooth extraction operation, and the stability of the back dental insert in the tooth extraction process is improved.

Furthermore, a T-shaped clamp extends out of the model base towards the rear tooth plug-in unit, and the rear tooth plug-in unit is provided with a clamping groove; the model base and the back tooth insert form tight fit. The checkpost is the T shape, has increased the area of contact of checkpost and back tooth plug-in components for the combination of model base and back tooth plug-in components is inseparabler.

Furthermore, a bottom plate is arranged below the model base, and a front tooth structure is arranged above the bottom plate; the section of the front tooth structure extends out of the clip, and the T-shaped bottom end of the clip is connected to the bottom plate. The T-shaped bottom end of the clip is connected to the bottom plate, so that the long-strip-shaped clip is prevented from being broken, and the stability of the model base combined with the rear tooth insert is improved.

Further, both ends of the anterior tooth structure are connected with posterior tooth inserts. Both ends of the front tooth structure are connected with the rear tooth insert, and both ends can be used for simulating tooth extraction.

Further, the simulated bone structure is transparent. The transparent simulated bone structure is convenient for observing the position of the tooth to be extracted in real time in the process of tooth extraction exercise.

Furthermore, two teeth are arranged on the rear tooth insert, wherein one tooth far away from the front tooth structure on the model base is a wisdom tooth. When the wisdom teeth are pulled out in a simulated mode, teeth close to the wisdom teeth are easy to damage, and the wisdom teeth and the easy-to-damage teeth are integrated on the front tooth structure at the same time, so that the front tooth structure can be conveniently replaced after the teeth pulling exercise; avoid the damage of the tooth on the model base, also make things convenient for the reuse of model base.

Furthermore, the simulated gum is a soft structure, and the simulated bone structure and the simulated teeth are hard structures. The real touch feeling and the hardness of the corresponding structure of the human body are simulated.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: the back dental insert consists of three structures of a simulated bone structure, a simulated tooth and a simulated gum, fully simulates the internal structure of the tooth, and forms a more vivid tooth extraction environment which can be practiced, so that the model has high simulation degree and good simulation operation effect; in addition, because simulation bone structure, simulation tooth, simulation gum three integrated into one piece, and back dental insert is printed by 3D and is formed for the connection effect of simulation bone structure, simulation tooth, simulation gum is good, does not need additionally to use binder etc. to bond between the three, makes the inside combination of whole back dental insert inseparable, and the simulation effect is good.
