Description

Technical Field

[0001] The utility model relates to the technical field of oral orthodontic teaching appliances, in particular to an oral orthodontic simulation training model. Background Art

[0002] Orthodontic treatment mainly uses various correction devices to adjust the positional relationship of facial bones, teeth, and alveolar bones to achieve balance, stability, and beauty of the oral and maxillary system. The correction of malocclusion mainly relies on wearing orthodontic appliances inside or outside the mouth to apply appropriate "biological forces" to the teeth, alveolar bones, and jaws to make them move accordingly. Through the control of support, different amounts of movement of teeth in different positions can be achieved, thereby correcting malocclusion.

[0003] Since the average course of orthodontic treatment is about two years, it is difficult for beginners to complete the entire treatment of a case. In order to enable orthodontic beginners to master more skills in a short period of time, a visual orthodontic operation model is usually used in orthodontic experimental teaching to simulate the clinical correction process to improve teaching effectiveness. Traditional orthodontic operation models usually include a metal jaw frame, on which the upper and lower jaws of the wax ridge are set, and various types of malocclusion teeth are arranged in the wax ridge of the dental model wax. During the experimental operation, the brackets are bonded, the corresponding orthodontic archwires are placed into the slots, and then the wax ridges are placed in a water bath at about 60°C. When the wax ridge is softened by heat, the teeth slowly move to their normal positions under the action of the archwire force. During this process, students can visually observe the accelerated correction process and deepen their learning and understanding. However, because the water bath heats the model as a whole, it is impossible to achieve different degrees of softening of wax blocks in different areas, and it is impossible to simulate the control of different tooth anchors. The alveolar bone is composed of cancellous bone and cortical bone. During the orthodontic tooth movement, the movement speed will slow down after hitting the cortical bone. The wax dam made of a single material cannot accurately simulate the movement process of teeth in the alveolar bone. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an oral orthodontic simulation training model which accurately simulates the dynamic movement change process of teeth under different anchorage controls and the treatment effect during orthodontic treatment.

[0005] The technical scheme adopted by the utility model is: an oral orthodontic simulation training model, comprising a jaw frame, a wax ridge is arranged on the jaw frame, the wax ridge comprises cancellous bone simulated by dental model wax, the cancellous bone is wrapped in cortical bone simulated by red and white proofing paste, a tooth model is arranged in the wax ridge, the tooth model comprises a crown and a tooth root embedded in the cancellous bone, a heating device is arranged on the tooth root, the heating device adopts an electrically heated heat source, and a heating switch and a heating temperature are controlled by powering on.

[0006] Furthermore, the thickness of the red and white proofing paste is 2 mm.

[0007] Furthermore, the heating device is arranged inside the tooth root.

[0008] Furthermore, the heating device adopts a conformable heating sleeve covering the tooth root.

[0009] Furthermore, the conformable heating sleeve is an electric heating wire mesh.

[0010] Furthermore, the tooth models of the molar area and the anterior tooth area are grouped to control the heating temperature.

[0011] Furthermore, the heating temperature is set to a plurality of different temperature levels.

[0012] The utility model has the following beneficial effects:

[0013] 1) Each tooth in the model is independent and can be simulated individually according to the patient's different dental conditions.

[0014] 2) During orthodontic tooth movement, the movement speed will slow down after hitting the cortical bone. The model simulates the cortical bone and cancellous bone to more realistically reflect the relationship between the teeth and the alveolar bone.

[0015] 3) The heating device is set on the tooth root to better simulate the real bone remodeling process after the tooth is stressed.

[0016] 4) Add different front and rear tooth position controls to simulate the anchorage design and reflect the treatment process more realistically.

[0017] 5) The model can be reused.

[0018] 6) Simple operation, just turn on the power. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to better understand the purpose, structure and function of the present invention, an orthodontic simulation training model of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1~Figure 4 As shown, an oral orthodontic simulation training model includes a jaw frame 1, a wax dam 2 is arranged on the jaw frame 1, the wax dam 2 includes cancellous bone 21 simulated by dental model wax, the cancellous bone 21 is wrapped in cortical bone 22 simulated by red and white proofing paste, a tooth model 3 is arranged in the wax dam 2, the tooth model 3 includes a crown 31 and a tooth root 32 embedded in the cancellous bone 21, a heating device 4 is arranged on the tooth root 32, the heating device 4 adopts an electrically heated heat source, and the heating switch and the heating temperature are controlled by powering on.

[0026] In this embodiment, in the wax bank 2 simulating the alveolar bone, 2 mm thick red and white proofing paste is used to simulate the cortical bone 22, and dental model wax is used to simulate the cancellous bone 21. It can accurately simulate that during the orthodontic tooth movement process, the movement speed will slow down after encountering the cortical bone 22.

[0027] The heating device 4 can be directly arranged inside the tooth root 32. In an optional embodiment, the heating device 4 adopts a conformable heating sleeve 41 that covers the tooth root 32. The conformable heating sleeve 41 can be made of a heat-conducting material. The heat source provided in the heating device 4 is connected to the conformable heating sleeve 41 to conduct heat. In this embodiment, the conformable heating sleeve 41 adopts an electric heating wire mesh, and the electric heating wire mesh itself serves as a heat source. The shape of the electric heating wire mesh is similar to that of the tooth root, wrapping around the tooth root 32, and the uniform distance from the tooth root 32 is 1 mm. Since the shape of the tooth root 32 of each tooth is different, the electric heating wire mesh of each tooth has a fixed shape. Orthodontic tooth movement will cause the reconstruction of the alveolar bone. The reconstruction of the alveolar bone first occurs around the tooth root 32. The shape of the heat source wraps around the tooth root, which can more truly reflect the process of bone reconstruction.

[0028] During orthodontic treatment, the support design for teeth in different positions is particularly important. Reasonable support design can accurately control the amount of orthodontic tooth movement. This embodiment simulates support differences by designing heat sources differently in the front and back tooth regions. The electric heating wire mesh in the molar area is controlled by the first control switch 42, and three gears are designed: the maximum temperatures are 50°C, 40°C, and 30°C respectively; the electric heating wire mesh in the front tooth area is controlled by the second control switch 43, and the second gear is designed: the maximum temperatures are 50°C and 30°C respectively.

[0029] The working principle of the utility model is as follows:

[0030] After the disordered teeth are glued on the brackets and the archwires are placed, the wax is heated and softened, and the teeth move along with the shape of the archwire, simulating the movement of teeth during orthodontics. The special shape design of the electric heating wire mesh wrapping the tooth root makes the wax around the electric heating wire mesh melt first, resulting in corresponding tooth movement, simulating the alveolar bone reconstruction and tooth movement under physiological conditions.

[0031] The red and white proofing paste and dental model wax soften to different degrees at the same temperature. At the same temperature, the red and white proofing paste is harder and the dental model wax is softer. This simulates the different reactions of the alveolar bone cancellous bone and cortical bone after the same force is applied (the cortical bone is hard and the cancellous bone is soft).

[0032] Different temperature levels are designed for the front and back teeth. The dental model wax softens to different degrees at different temperatures. The teeth move faster in the softer dental model wax. Different support is designed to simulate the orthodontic process (the stronger the support, the smaller the tooth movement).
