This solves the problem in existing technologies where, during the process of performing full crown restoration around a second-tooth malformation model, the area between it and adjacent full-tooth models or first-tooth malformations is small, easily causing interference and affecting the wax drip restoration of the second-tooth malformation model.

Description

Technical Field

[0001] This application relates to the field of oral teaching aids and models, and in particular to a denture teaching model. Background Technology

[0002] In current dental education, prosthetic models are often used to visually demonstrate tooth morphology to students. For example, when teaching the restoration of missing tooth crowns, various models of missing teeth are needed, such as models of first missing teeth with partial defects in different areas and models of second missing teeth with complete crown defects. Wax is then applied to the first and second missing tooth models using an electric wax applicator to repair the missing crown, thus effectively demonstrating the wax application process.

[0003] However, in the process of arranging existing first and second missing tooth models, a full tooth model with a complete crown is required as a reference. After the full tooth model is arranged, the distance between the existing second missing tooth model and the full tooth model or the first missing tooth model becomes relatively close. In particular, when it is necessary to apply wax to the second missing tooth model to restore the entire crown, it is necessary to use an electric wax cutter to repair the second missing tooth model around its entire circumference. During the circumference operation, it is necessary to pass through the area between the second missing tooth model and the full tooth model or the first missing tooth model. However, due to the need for miniaturization of the model as a whole for easier use, the area between the second missing tooth model and the full tooth model or the first missing tooth model is relatively small. This makes it inconvenient for the electric wax cutter to operate in a small area, affecting the wax application restoration of the second missing tooth model.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a denture teaching model that solves the problem that in the process of performing full crown restoration around the second missing tooth model, the area between the denture and the adjacent full tooth model or the first missing tooth model is small, which easily causes interference and thus affects the wax drip restoration of the second missing tooth model.

[0006] This application provides a denture teaching model, including: a support plate, on which an installation part is provided;

[0007] Multiple first tooth malformation models, each with a missing crown, and each missing crown has a gap area, but the gap area is different for each first tooth malformation model;

[0008] The docking part is fitted with the mounting part and is detachably connected to the carrier plate through the mounting part;

[0009] The second missing tooth model is set on the mating part, and the crown of the second missing tooth model is completely missing.

[0010] Optionally, the mounting section includes a mating groove formed on the upper surface of the support plate;

[0011] The mating component includes a mating block, which connects to the second tooth defect model and is pluggable in the mating slot.

[0012] Optionally, the mating groove includes: a groove cavity, the groove cavity being open on the outside away from the central axis of the bearing plate to form an insertion / removal port;

[0013] The limiting stop is set on both sides of the upper opening of the groove cavity, and a limiting groove is formed between the lower surface of the limiting stop and the bottom surface of the groove cavity.

[0016] Optionally, a first inner fillet is provided between the lower surface of the limiting stop and the inner wall of the groove, and a first outer fillet is provided between the upper surface of the limiting side and the side of the limiting side.

[0017] A second inner fillet is provided between the lower surface of the limiting stop and the side wall of the limiting stop, and a second outer fillet is provided between the upper surface of the limiting platform and the side of the mating block.

[0018] Optionally, anti-detachment components are provided on the docking parts and the carrier plate, which are used to lock the docking parts onto the carrier plate;

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer and more explicit, the following detailed description of this application is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0035] like Figure 1 , Figure 2 As shown, this embodiment proposes a denture teaching model, mainly including: a support plate 100, multiple first tooth defect models 200, a connector 300, and a second tooth defect model 400. The support plate 100 in this embodiment can be a disc structure. For ease of structural description, a horizontal disc configuration is used as an example. The multiple first tooth defect models 200 can be fixedly mounted on the upper surface of the support plate 100. Each of the multiple first tooth defect models 200 has a missing crown, and the missing crown has a missing area 210. The missing area 210 of each first tooth defect model 200 is different. By making the missing crowns have different missing areas 210, different appearances of missing teeth can be shown through the multiple first tooth defect models 200, facilitating students' intuitive understanding of the specific morphology of different missing crowns. In this embodiment, the second missing tooth model 400 can be fixedly mounted on the docking member 300, so that the second missing tooth model 400 and the docking member 300 are set as a whole separately. The crown of the second missing tooth model 400 is completely missing, so the second missing tooth model 400 mainly represents the morphology of a tooth without a crown, while the first missing tooth model 200 represents the situation where the crown is partially missing. A mounting part 110 is provided on the support plate 100, and the docking member 300 is matched with the mounting part 110 and detachably connected to the support plate 100 through the mounting part 110; therefore, the second missing tooth model 400 can be removed from the support plate 100 or mounted on the support plate 100.

[0036] like Figure 1 , Figure 2As shown, in this embodiment, the prosthetic teaching model arranges multiple first tooth malformation models 200 with different missing areas 210 on a support plate 100, and a mounting part 110 is provided on the support plate 100. A second tooth malformation model 400 with a completely missing crown is placed on a docking part 300. The docking part 300 and the mounting part 110 cooperate to detachably connect the second tooth malformation model 400 to the support plate 100. When teaching how to repair the crown with wax dripping, the docking part 300 can be removed from the mounting part 110, thereby detaching the second tooth malformation model 400 from the support plate 100. This allows the second tooth malformation model 400 to be separated from the multiple first tooth malformation models 200 on the support plate 100. During the process of repairing the missing crown of the second tooth malformation model 400 with an electric wax cutter, the operation can be performed smoothly around the entire crown without interference or influence from other tooth models on the support plate 100. After the repair is completed, the second tooth defect model 400 is installed on the carrier plate 100 by matets the docking part 300 with the mounting part 110, and is presented together with other tooth models on the carrier plate 100 to improve the teaching effect.

[0037] like Figure 1 , Figure 2 As shown, further, the mounting part 110 of this embodiment specifically includes a docking groove 120, which is formed on the support plate 100. For example, the docking groove 120 can be formed on the outer circumferential side of the support plate 100, and an opening is also formed on the upper surface of the docking groove 120. The docking groove 120 only occupies a part of the overall thickness of the support plate 100, so the docking groove 120 has an inner bottom surface. The docking member 300 includes a docking block 310, which connects to the second tooth defect model 400. The docking block 310 is pluggable in the docking groove 120. When the docking block 310 is inserted into the docking groove 120 from the side, the second tooth defect model 400 protrudes from the opening on the upper surface of the docking groove 120, so that it can protrude from the upper surface of the support plate 100 and be displayed together with the other first tooth defect models 200. By inserting the docking block 310 into the docking groove 120 from the side, the docking block 310 can be pulled out radially along the support plate 100. In this way, the movement direction of the second tooth missing model 400 on the docking block 310 is directly away from other models on the support plate 100, thus making it less likely for other models to collide.

[0038] It should be noted that the docking groove 120 can also be formed on the upper surface of the carrier plate 100, and the docking groove 120 can also penetrate the carrier plate 100 in the vertical direction. In this way, the docking block 310 can be directly inserted and pulled from the upper surface of the carrier plate 100 in the vertical direction, which can also achieve the technical effect.

[0039] like Figure 2 , Figure 3 , Figure 4 As shown, the docking groove 120 in this embodiment further includes a groove cavity 121 and a limiting stop 123. The groove cavity 121 is open on the outer side away from the central axis of the support plate 100 to form an insertion port 122. The insertion port 122 is provided on the outer wall of the side of the support plate 100 to facilitate the docking block 310 to enter and exit the groove cavity 121 radially. The limiting stop 123 is provided on both sides of the upper opening of the groove cavity 121, and a limiting groove 124 is formed between the lower surface of the limiting stop 123 and the bottom surface of the groove cavity 121. Limiting steps 320 are provided on both sides of the docking block 310. The limiting steps 320 are used to be inserted into the limiting groove 124 through the insertion port 122. The width of the opening formed by the limiting grooves 124 on both sides is smaller than the width of the inner bottom surface of the groove cavity 121, so that the limiting side platform 320 can be limited in the vertical direction, and the limiting side platform 320 can slide in and out radially along the limiting groove 124, thereby achieving more stable insertion and removal of the docking block 310.

[0040] like Figure 1 , Figure 2 As shown, in this embodiment, the mating block 310 and the slot cavity 121 are both fan-shaped. The fan-shaped mating block 310 can stably match the entire disc-shaped support plate 100, and can be considered as a portion of the disc surface of the support plate 100, excluding the central area. This makes the surface shape of the support plate 100 uniform after installation on it. In addition, by using a fan-shaped mating block 310, the arc length of the end of the mating block 310 facing the center is less than the arc length of the outer wall of the mating block 310. Therefore, during the process of inserting the mating block 310 into the slot cavity 121, the end with the shorter arc length enters the insertion port 122 first. Since the insertion port 122 is large, it can quickly enter the insertion port 122. Subsequently, during the process of pushing the mating block 310, it can be automatically guided and aligned, making the insertion process more convenient.

[0041] like Figure 2 , Figure 3 , Figure 4As shown, further, a first inner fillet 125 is provided between the lower surface of the limiting stop 123 and the inner sidewall of the groove 121, and a first outer fillet 321 is provided between the upper surface of the limiting platform 320 and the side surface of the limiting platform 320. A second inner fillet 126 is provided between the lower surface of the limiting stop 123 and the sidewall of the limiting stop 123, and a second outer fillet 322 is provided between the upper surface of the limiting platform 320 and the side surface of the mating block 310. Due to the fan-shaped structure, the shorter end of the mating block 310 enters the insertion port 122 first. Because the insertion port 122 is relatively large, the inner wall of the cavity 121 needs to guide the limiting platform 320 on one side in the left-right direction. On the other side in the left-right direction, the rounded corner of the second inner rounded corner 126 can form a certain guiding pressure on the first outer rounded corner 321 on the limiting platform 320. In this way, during the inward insertion process, it gradually moves towards the limiting slide groove 124, and then the first outer rounded corner 321 on the limiting platform 320 reaches the position of the first inner rounded corner 125, thereby achieving matching and limiting. In addition, the second inner rounded corner 126 and the second outer rounded corner 322 can also match and limit in the end.

[0042] like Figure 3 , Figure 5 As shown, in another structure, the docking block 310 and the docking groove 120 are prone to wear and tear during long-term use, which can easily cause the docking part 300 to become relatively loose from the support plate 100. If it easily falls off, the docking part 300 is easily lost, which is detrimental to the storage and maintenance of the teaching aid. Therefore, an anti-detachment component 500 is provided on the docking part 300 and the support plate 100. The anti-detachment component 500 is used to lock the docking part 300 onto the support plate 100. When in use, the anti-detachment component 500 can be loosened before using the teaching aid; when not in use, the anti-detachment component 500 is locked, thus preventing the docking part 300 from easily falling off the support plate 100.

[0043] like Figure 3 , Figure 5As shown, further, a threaded hole 140 is provided on the support plate 100, and a countersunk hole 150 is provided on the upper part of the threaded hole 140. The countersunk hole 150 is formed on the support plate 100 and the docking member 300. In the specific structure, a small half of the countersunk hole 150 is formed at the edge of the upper surface of the docking member 300, and a large half of the countersunk hole 150 is formed on the support plate 100, located at the edge of the upper opening. After the docking member 300 is inserted into the docking groove 120 and docked with the support plate 100, the two halves of the countersunk hole 150 are also spliced ​​to form a complete countersunk hole 150. The anti-detachment component 500 specifically includes: a locking stud 510 and a locking pressure head 520. The locking stud 510 is disposed in the threaded hole 140, and the locking pressure head 520 is connected to the locking stud 510. By turning the locking stud 510, the locking pressure head 520 is moved out or into the countersunk hole 150. After the complete countersunk hole 150 is assembled, the locking head 520 is lowered by tightening the locking stud 510, thus embedding the locking head 520 into the countersunk hole 150 and locking the mating part 300 onto the support plate 100 to prevent it from coming out. If the model needs to be used, the locking head 520 is raised by tightening the locking stud 510, thus disengaging it from the countersunk hole 150 and unlocking the mating part 300.

[0044] like Figure 3 , Figure 5 As shown, it should be noted that, to facilitate the tightening of the locking stud 510, a tightening handle can be provided on the locking head 520 for easy tightening. Alternatively, the locking head 520 can be directly set as an internal hex screw head, which can also be operated using an internal hex wrench.

[0045] like Figure 1 , Figure 2 As shown, further, after the docking component 300 of this embodiment is installed on the support plate 100, multiple first tooth defect models 200 and second tooth defect models 400 are evenly distributed around the central axis of the support plate 100. The multiple first tooth defect models 200 and second tooth defect models 400 are distributed in a circumferentially spaced manner, which can effectively utilize the surface space of the plate and reduce the area occupied by the entire teaching aid.

[0046] like Figure 1 , Figure 2 As shown, in this embodiment, a full tooth model 160 is further provided at the central axis position of the support plate 100. The full tooth model 160 is a complete tooth model with a complete crown, and is therefore positioned in the middle of the support plate 100 as a reference, so that there is a visual repair standard when repairing other missing teeth.

[0047] like Figure 1 , Figure 2As shown, further, in this embodiment, the missing areas 210 of the multiple first tooth-deficiency models 200 are all located on the side facing outwards, away from the central axis of the support plate 100. Since the missing areas 210 of the first tooth-deficiency models 200 all face outwards, during repair, the wax applicator only needs to apply wax to the outside of the model, avoiding the influence of other models on the operation. A retaining block 220 is also provided in the missing area 210. The retaining block 220 provides an adsorption and support position for the repair wax, facilitating stable adhesion of the repaired wax to the missing area 210 and improving the stability of the repaired wax.

[0048] like Figure 1 , Figure 2 As shown, further, the surface of the carrier disk 100 in this embodiment is provided with a marking portion 170, which is used to mark the tooth name, wherein the multiple first tooth defect models 200 and second tooth defect models 400 are models with the same tooth name. The tooth models on the entire carrier disk 100 can correspond to the same tooth, therefore the specific name of the tooth can be marked by the marking portion 170, making teaching more convenient. The marking portion 170 can adopt a raised letter structure and is arranged around the central axis of the carrier disk 100.

[0049] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
