Description

Technical Field

[0001] The utility model relates to the technical field of dental models, in particular to a dental and dental arch cognitive model. Background Art

[0002] The anatomical shape of teeth and tooth identification are the key points and difficulties in the teaching of oral anatomy and physiology. Mastering and correctly identifying the tooth morphology is the basic requirement for every student majoring in stomatology. However, due to the relatively complex morphological structure of each tooth and individual differences, it adds a lot of difficulty to the teaching of tooth anatomical shape.

[0003] In traditional multimedia teaching, teachers mainly teach through means such as text, pictures and videos. Students passively learn and accept relevant knowledge, and it is even more difficult to observe and identify the similarities and differences in the morphological structures of each tooth from multiple angles and in an all-round way in an active and interesting manner. At the same time, due to the limited number of clinical collected extracted teeth, there are not enough extracted tooth specimens for students to learn in teaching, which brings great difficulties for students to establish an accurate three-dimensional cognition of tooth shape in a short time.

[0004] Therefore, there is an urgent need in teaching for a dental and dental arch cognitive teaching model that can allow students to actively challenge and learn interestingly, has intuitive and three-dimensional perception of standard tooth morphological characteristics, and can be used for self-study and competition, so as to improve students' initiative, interest and the quality of curriculum teaching in the tooth external structure and dental arch cognition.

[0005] Currently, the commonly used teaching models have an alveolar arch, and a plurality of alveolar sockets are arranged on the alveolar arch. A tooth model is inserted into each alveolar socket. The root specifications of the existing tooth models are different, that is, the tooth roots of the tooth models and the alveoli are in a one-to-one correspondence relationship, and the installation of the tooth models is not easy to be confused. In addition, there is a limiting structure between the tooth roots of the existing tooth models and the corresponding alveoli, so that the installation direction of the tooth models is fixed and multi-directional insertion tests cannot be realized.

[0006] Therefore, when the existing teaching models are used, the tooth models can only be correspondingly installed in the corresponding alveoli, and the installation direction is fixed. That is, even if students do not understand the arrangement of teeth, they will not make mistakes, which fails to achieve the learning and training effects. Summary of the Invention

[0007] Aiming at the defects in the prior art, the technical problem to be solved by the utility model is to provide a dental and dental arch cognitive model to facilitate learners to quickly master the external shape of teeth and the arrangement of tooth positions.

[0008] To solve the above technical problems, the present utility model provides a dental and dentition cognitive model, which includes an alveolar model. A plurality of alveolar sockets are provided on the alveolar model, and a tooth model is inserted into each of the alveolar sockets. The tooth model includes a crown and a root, and the root is rotatably inserted into the corresponding alveolar socket; the cross-sectional shapes of the alveoli are the same, and the cross-sectional shapes of the roots are the same.

[0009] Preferably, the cross-sections of the alveolar sockets and the roots are both rectangles with the same dimensions.

[0010] Preferably, the outer dimension of the crown is larger than the outer dimension of the root.

[0011] Preferably, the alveolar model has a U-shaped alveolar arch, and the alveolar sockets are provided on the alveolar arch.

[0012] Preferably, the alveolar arch includes two symmetrically arranged alveolar parts, and the two alveolar parts include the same number of alveolar sockets.

[0013] Preferably, the cross-sections of the alveolar sockets and the roots are both squares with the same dimensions.

[0014] Preferably, there is a gap between adjacent crowns to facilitate the insertion of the tooth model.

[0015] Preferably, the gap is (0.4 - 0.6) mm.

[0016] Preferably, a QR code is provided at one end of the root away from the crown to facilitate obtaining information about the tooth model by scanning the code.

[0017] The present utility model has the following beneficial effects: The dental and dentition cognitive model of the present utility model has an alveolar model and a tooth model. The root of the tooth model can be rotatably inserted into the alveolar socket on the alveolar model, so that the tooth model is detachably connected to the alveolar model, and the circumferential angle is fixed after connection, which is convenient for learners to practice repeatedly. And the cross-sectional shapes of the alveolar sockets are the same, and the cross-sectional shapes of the roots are also the same, that is, the connection structures of the roots and the alveolar sockets are the same, so it is impossible to determine the correct alveolus corresponding to the tooth model according to the matching relationship between the root and the alveolar socket, which is beneficial to help learners master the correct arrangement of tooth positions. In addition, the crown of the tooth model simulates the shape of real teeth, which can facilitate learners to master the shape of the tooth body. Description of the Drawings

[0025] Here, it should be noted that the functions, methods, etc. involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention over the prior art lies essentially in the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is for better explaining the present invention and facilitating a better understanding of the present invention.

[0026] The following will describe in detail the embodiments of the technical solutions of the present invention with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and therefore are only examples and cannot be used to limit the protection scope of the present invention.

[0027] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present invention belongs.

[0028] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, this embodiment provides a dental and dentition cognitive model, including an alveolar model 1. A U-shaped alveolar arch 11 is provided on the alveolar model 1. The alveolar arch 11 includes two symmetrically arranged alveolar parts on the left and right. The two alveolar parts include the same number of alveolar sockets 111. In this embodiment, the total number of alveolar sockets 111 is 14, and each alveolar part has 7 alveolar sockets 111. In practice, the number of alveolar sockets 111 can also be 16 (permanent teeth) or 10 (primary teeth).

[0029] A tooth model 2 is inserted into each alveolar socket 111. The tooth model 2 includes a tooth crown 21 and a tooth root 22. The tooth root 22 is non-rotatably inserted into the corresponding alveolar socket 111. In this embodiment, the cross-sectional shapes of the alveolar sockets 111 are the same, and the cross-sectional shapes of the tooth roots 22 are the same. The cross-sections of the alveolar sockets 111 and the tooth roots 22 are both squares with the same size. Using square plug-in fit can not only achieve the free insertion of the tooth root 22 and the alveolar socket 111 without being restricted by the insertion direction, but also achieve the non-rotating connection between the tooth root 22 and the alveolar socket 111. In practice, the cross-sectional shapes of the alveolar sockets 111 and the tooth roots 22 can also be rectangles with the same size. This cross-sectional shape limits the two insertion directions of the tooth root 22, so that the tooth root 22 can only be inserted into the alveolar socket 111 along two directions. In practice, the cross-sectional shapes of the alveolar sockets 111 and the tooth roots 22 can also be cylindrical. This cross-sectional shape allows the tooth root 22 to be inserted in any direction, so that the tooth root 22 can be inserted into the alveolar socket 111 in any direction.

[0030] Specifically, the outer dimension of the tooth crown 21 is larger than the outer dimension of the tooth root 22, and there is a gap of (0.4 - 0.6) mm between two adjacent tooth crowns 21 after installation. In this embodiment, the gap is about 0.5 mm, making the insertion of the tooth model 2 more convenient.

[0031] Furthermore, a two-dimensional code is printed on the end of the tooth root 22 away from the tooth crown 21. Then, learners can scan the two-dimensional code to learn the typical features and related knowledge of the tooth model 2, and understand the correct tooth position of the tooth model 2 on the alveolar model 1.

[0032] Reference Figure 4 , when using the dental and dentition cognitive model of this embodiment, directly install it on the corresponding alveolar socket 111 of the alveolar model 1. If the installation is correct after inspection, you can continue to learn in combination with adjacent teeth and the opposing teeth. If the installation is incorrect after inspection, you can scan the two-dimensional code on the corresponding tooth model 2 to learn online, and then install it on the alveolar model 1 after understanding the tooth position corresponding to the tooth model 2.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
