Description

Technical Field

[0001] The utility model relates to an orthodontic teaching demonstration and training model, belonging to the technical field of stomatology. Background Art

[0002] The teaching of orthodontics not only includes theoretical learning, but also model operation which is an important part. The orthodontic teaching model can be used as a teaching aid to help students more intuitively understand the principles, techniques and operation steps of orthodontic treatment. Students can use the model for operation training, observe the process of tooth movement, master the use method of instruments, etc., so as to deepen the understanding and mastery of the orthodontic discipline. At present, most of the existing orthodontic teaching models use red wax to simulate the alveolar bone. By heating in a water bath, the red wax can be softened, and the tooth roots can move, so as to simulate the effect of tooth alignment. However, such models have some disadvantages: 1) Heating in a water bath requires a water bath device, which is not convenient to carry and move; 2) After the teeth are aligned and then restored to the malocclusion state, manual tooth arrangement and remolding of red wax are required, which is not convenient. 3) The way of heating in a water bath makes the red wax gradually soften from the outside to the inside, and its softening speed and degree are not consistent at each point, which does not conform to the actual situation that the alveolar bone near the tooth root is rebuilt first during orthodontics. Summary of the Invention

[0024] This embodiment provides an orthodontic teaching demonstration and training model, as Figure 1 shown. The model includes an upper dental arch mold 1, a lower dental arch mold 2, artificial teeth 3, a malocclusion reduction template 4 and an electric heating temperature control component. Both the upper dental arch mold 1 and the lower dental arch mold 2 are bow-shaped and are in a rotational connection relationship. Among them, the upper dental arch mold 1 includes an upper jaw frame 11 and an upper jaw bone 12 installed on the upper jaw frame; the lower dental arch mold 2 is provided with a lower jaw frame 21 and a lower jaw bone 22 installed on the lower jaw frame. The artificial teeth 3 are divided into upper artificial teeth and lower artificial teeth. The artificial teeth 3 include a root pressing part 31 and a crown part 32 that can be detachably assembled.

[0025] In this embodiment, the upper dental arch mold 1 and the lower dental arch mold 2 are rotationally connected through a hinge shaft. In this embodiment, it is preferably connected by a sagittal axis 7. The sagittal axis 7 is provided with three rotating shaft holes, and the sagittal relationship between the upper and lower jaws is changed by switching the rotating shaft holes to simulate the malocclusion types with sagittal disharmony.

[0026] In this embodiment, the upper jaw bone 11 and the lower jaw bone 21 have a hard outer shell. A filling material 8 is provided inside the hard outer shell, and artificial teeth are embedded in the filling material; the filling material is selected from thermoplastic plastics or wax, which becomes soft when heated and hard in a cooled state. The outer side of the hard outer shell is coated with a simulated gum material to form a layer of highly simulated gums.

[0027] In this embodiment, the root part 31 of the artificial tooth is made of a metal material. The crown part 32 of the artificial tooth includes a metal inner core and an outer shell connected to the root pressing part 31. The outer shell of the crown part is detachable and is made of synthetic resin, so as to simulate teeth of different sizes and shapes, and is also beneficial to the update after the surface of the artificial tooth is damaged after repeatedly bonding brackets.

[0028] In this embodiment, an electric heating element 5 is provided inside the tooth root 31 of the artificial tooth, a temperature sensing element 6 is provided in the filling material, an operation module 13 is installed on the upper jaw mount 11, and a switch button, a temperature adjustment button and a time adjustment button are provided on the operation module 13; a control module 23 is provided on the lower jaw mount 21, and a power supply module 24 for supplying power to the electric heating element 5, the temperature sensing element 6, the control module 23 and the operation module 13, and the power supply module can be powered by a storage battery or an external 220V AC power supply; wherein, the electric heating element 5 can be a heating wire or a heating sheet, and the heating wire can be buried into the tooth root 31 of the artificial tooth through the apical foramen.

The controllable electric heating component can selectively heat the filling material to a certain temperature without damaging the wax structure or the metal tooth.

[0029] In this embodiment, the malocclusion reduction template 4 is a female mold made with the crown core part of the artificial tooth as the male mold, and is made of a hard material, and is cut into a buccal part 41 and a lingual part 42, and the head and tail ends are respectively fixedly connected by a pin 43. Cutting it into two parts is to facilitate the reduction of the artificial tooth, and when put together again, the artificial tooth can be completely reduced. When in use, first use the outer buccal part 41. When the filling material is heated and softened, move the artificial tooth to the position corresponding to the outer guide plate, place the inner lingual part 42, and then fix it with a pin. Turn off the heating of the filling material, and after cooling, take out the malocclusion reduction template 4, and the artificial tooth can be arranged according to the shape preset by the guide plate.

[0031] Setting: When initializing the model, install the artificial tooth in a preset incorrect alignment position.

[0032] Activation: Heat by starting the electric heating component to activate the model. After heating, the filling material around the metal tooth is softened so that the tooth can move.

[0033] Adjustment: When the filling material is softened, a preset orthodontic arch wire (which has been set to the final desired position of the tooth, and the orthodontic arch wire is an orthodontic arch wire commonly used in the prior art and is not included in this model) applies force to guide the tooth to move to a new position.

[0034] Cooling and resetting: After adjustment, the model is cooled to solidify the filling material and lock the tooth in the new position. This process can be repeated to simulate different stages of orthodontic adjustment.

[0035] The above are only the preferred embodiments of the present utility model, and do not impose any formal or substantial limitations on the present utility model.
