Portions 22 are located behind the tooth bodies 12 . The gum structure 2 is also produced by 3D printing.

Referring to FIGS. 4 to 6 , the sensing unit 3 includes two sensing elements 31 respectively embedded in the extending portions 22 of the gum structure 2 and located behind the tooth bodies 12 , and a light-emitting element electrically connected to the sensing elements 31 . components 32 and a battery 33 disposed on the mandible body 11 and electrically connected to the sensing components 31 . Each sensing element 31 has a main body 311 , an insulating layer 312 covering the main body 311 , and an outer conductive layer 313 covering the insulating layer 312 . The insulating layer 312 is made of silica gel, and the outer conductive layer 313 is made of conductive material. The positions of the sensing elements 31 roughly correspond to the positions of the alveolar nerves of the human body. When the user can use a metal needle 10 to pierce the gum structure 2 for a simulated exercise of anesthesia injection, when the metal needle 10 pierces the When the gum structure 2 , the outer conductive layer 313 and the insulating layer 312 are in contact with the main body 311 of the sensing element 31 , the battery 33 , the main body 311 of the sensing element 31 , the outer conductive layer 313 , the metal needle 10 and the A passage is formed between the light-emitting elements 32, and the light-emitting element 32 emits light, indicating that the metal needle 10 has been injected to the correct position, and the user can get more feedback during the simulation exercise to know whether the operation method is correct. In other embodiments, the number of the sensing element 31 may be only one, which is embedded in one of the extending portions 22 .

To sum up, the present novel tooth model teaching tool is provided with the sensing element 31 of the sensing unit 3 , when a metal needle 10 pierces the gum structure 2 and contacts the body of the sensing element 31 , the light emitting element 32 It can emit light as a prompt for the correct position of the metal needle 10 inserted into the gum structure 2, so as to improve the interactivity and allow the user to have more feedback in the process of practicing the operation with this teaching aid, which can be matched with the course or self Learning, using this feedback to increase the fun and feedback of learning, so it can indeed achieve the purpose of this new model.
