Impacted wisdom tooth removal model for teaching

Abstract

The embodiment of the invention provides an impacted wisdom tooth removal model for teaching. The impacted wisdom tooth removal model comprises an oral maxillofacial region structure, a fixed adapter,an oral opening and closing control structure and consumables, the oral maxillofacial region structure comprises an upper jawbone and a lower jawbone, the rear end of the upper jawbone is rotatably connected with the rear end of the lower jawbone, a lower tooth set is arranged on the lower jawbone, and an upper tooth set is arranged at the bottom of the upper jawbone; the oral cavity opening andclosing control structure is movably connected with the mandible; the fixed adapter is fixedly connected with the oral maxillofacial region structure; the consumables comprise a mucous membrane layer,mandible impacted wisdom teeth, mandible first molar teeth and mandible second molar teeth, the impacted wisdom tooth removal model for teaching provided by the embodiment of the invention is used for physician training projects, after training is completed, the consumables can be replaced by screwing bolts, and convenience and quickness are achieved; the consumables are made of simulation materials, bones and teeth of the surgical operation consumables are close to the hardness of real tissues, the simulation effect is good, and the teaching quality of impacted wisdom tooth extraction can beeffectively improved.

Description

technical field [0001] The invention relates to the technical field of models for teaching, in particular to an impacted wisdom tooth extraction model for teaching. Background technique [0002] At present, there are three kinds of existing teaching models, one is isolated teeth or resin teeth embedded in plaster, and the defects are as described in the text. The second type is the resin model, which is the most common, and it is also the same for the licensed doctor examination. It can only simulate simple tooth extraction, and cannot carry out impacted tooth extraction. The third is to use pig mandibles, which are similar to the operator’s touch, but the source is limited. Now a large number of meat pigs are suckling pigs, which are quite different from permanent tooth extraction. Most adult pigs are breeding pigs, and the number is very small. Secondly, there are biosafety hazard. None of the existing models can simulate the minimally invasive tooth extraction procedure...

AI Technical Summary

Problems solved by technology

[0003] In view of the technical problems in the prior art that the simulation effect of the oral cavity model is poor, the teaching mode is single, and it is not conducive to students' learning, the embodiment of the present invention provides a model for the extraction of impacted wisdom teeth for teaching
