Description

Technical Field

[0001] This utility model relates to the field of dental teaching demonstration technology, specifically a detachable dental instrument for dental teaching demonstration. Background Technology

[0002] The importance of dental demonstration models in clinical teaching is increasingly prominent. They have become a frequently used tool for doctors in simulated teaching and play an irreplaceable role. Demonstration models enable medical students to better absorb medical knowledge and skills, and their application in trauma-related teaching is particularly crucial. Using models in teaching allows students to learn medical knowledge in an environment without operational risks and to master medical knowledge through practical procedures. With the improvement of people's living standards, a series of oral diseases have come to people's attention, and dental models allow doctors to conduct simulated learning before interacting with patients.

[0003] Existing dental teaching demonstration models are displayed directly using a model of teeth that bite together. Most of the teeth on this model are detachable and can be directly inserted and removed from the crown. However, dental implantation is a complicated procedure, and using the insertion and removal method directly would result in an unclear demonstration and reduce the effectiveness of the demonstration. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable dental instrument for dental teaching demonstrations, in order to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable dental instrument for dental teaching demonstrations, comprising a dental instrument model, several teeth 1 embedded in the crown of the dental instrument model, and teeth 2 disposed on the lower crown, wherein a detachment part is installed between the teeth 2 and the lower crown, and the detachment part includes: A silicone sheet is attached to the crown of the dental model described below at one end and can be flipped over. A through hole is provided in the middle of the silicone sheet, and a silicone pad is attached to one side of the inner wall of the through hole. A threaded hole is provided at the crown of the lower dental model, and the threaded hole corresponds to the position of the through hole; The disassembly component is placed between the second tooth and the silicone skin for demonstrating the disassembly and assembly of the second tooth.

[0006] Preferably, the disassembly component includes: The fixed tube has threads on both its outer and inner walls, and the surface of the fixed tube is connected to the internal threads of the threaded hole. The fixing bolt penetrates the interior of tooth two and connects to the internal threads of the fixing tube.

[0007] Preferably, the disassembly component further includes a sealing plug embedded at the top of the second tooth, and the sealing plug is located above the fixing plug.

[0008] Preferably, a magnet is installed on the crown of the dental model described below, and an iron sheet that works in conjunction with the magnet is installed on the inner side of the silicone skin.

[0009] Preferably, the outer ring size of the silicone pad is adapted to the inner side of the through hole, and the silicone pad is flush with the underlying crown after being attached.

[0010] Preferably, the external and internal threads of the fixed tube are in opposite directions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When demonstrating dental implantation, the instructor can use a teaching scalpel to move along the gap between the silicone skin and the crown to demonstrate the skin cutting effect. Then, the fixing tube can be screwed into the threaded hole, and the second tooth can be positioned above the threaded hole. After the fixing pin passes through the second tooth, it is fixed to the internal thread of the fixing tube. This allows for the demonstration of the dental implantation steps, making it easier for others to learn and observe. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 As shown, a detachable dental instrument for teaching demonstration in dentistry includes a dental instrument model 100, several teeth 200 embedded in the crown of the dental instrument model 100, and teeth 300 set on the lower crown. A detachment part 400 is installed between the teeth 300 and the lower crown. The detachment part 400 includes a silicone skin 410 with one end bonded to the crown of the lower dental instrument model 100 and capable of being flipped. A through hole 420 is opened through the middle of the silicone skin 410. A silicone pad 430 is bonded to one side of the inner wall of the through hole 420. The outer circle size of the silicone pad 430 is adapted to the inner side of the through hole 420. After the silicone skin 410 is attached to the lower crown, it is flat. With this setting, the teeth 300 will not protrude after being installed on the crown of the lower dental instrument model 100.

[0016] The lower dental model 100 has a threaded hole 460 at the crown, which corresponds to the position of the through hole 420. A disassembly component 440 for demonstrating the disassembly and assembly of the second tooth 300 is provided between the second tooth 300 and the silicone skin 410. The disassembly component 440 includes a fixing tube 441 with threads on both the outer and inner walls. The surface of the fixing tube 441 is connected to the internal thread of the threaded hole 460. The external and internal threads of the fixing tube 441 are in opposite directions, so that when the fixing bolt 442 is screwed into the inside of the fixing tube 441, it will not cause the fixing tube 441 to loosen from the threaded hole 460. The fixing bolt 442, which is connected to the internal thread of the fixing tube 441, passes through the second tooth 300. It can be screwed into the threaded hole 460 through the fixing tube 441 by an external medical electric drill. After the second tooth 300 is located on the surface of the fixing tube 441, the fixing bolt 442 can be screwed into the fixing tube 441 through the second tooth 300 to facilitate the fixation of the second tooth 300.

[0017] Based on the above scheme, see Figures 3-5 The disassembly component 440 also includes a sealing plug 443 embedded in the top of the second tooth 300, and the sealing plug 443 is located above the fixing bolt 442. After the fixing bolt 442 is screwed in, the sealing plug 443 can be inserted into the top of the second tooth 300.

[0018] See Figure 4A magnet 470 is installed on the crown of the lower dental model 100, and an iron plate 450 that works with the magnet 470 is installed on the inner side of the silicone skin 410. With this arrangement, the silicone skin 410 is prevented from sliding or moving at will due to the mutual magnetic attraction between the magnet 470 and the iron plate 450.

[0019] Working principle: During use, the teaching knife can be moved along the gap between the silicone skin 410 and the crown. While moving, the silicone skin 410 can be flipped open. Then, the crown of the dental model 100 can be drilled with an electric drill to form a threaded hole 460. Next, the fixing tube 441 is screwed into the threaded hole 460. Then, the silicone skin 410 is reattached to the crown surface. The silicone pad 430 is cut open with the teaching knife to expose the fixing tube 441 from the through hole 420. Then, the second tooth 300 is placed on top of the fixing tube 441, and the fixing bolt 442 is screwed into the fixing tube 441 through the second tooth 300 with an external tool to fix the second tooth 300. The teaching can be carried out continuously during the operation. When disassembling, the above operation can be repeated.
