Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of dental orthodontics, and in particular to a dental model and an identification system. Background Art

[0002] Currently, the preparation of shell-shaped dental appliances typically involves several steps: 3D printing of the dental model, film preparation, lamination, shell-shaped appliance cutting, and cleaning. The 3D printing of the dental model requires a 3D printer using photosensitive resin as the raw material.

[0003] See also Figure 1 The printed dental model 100A typically includes a jaw portion 110A, a base 120A for supporting the jaw portion 110A, and an information block 140A on which an information code 130A is disposed. The information block 140A is a block-shaped object independent of the jaw portion 110A and the base 120A. The information block 140A is typically located lingually between the base 120A and the jaw portion 110A, allowing the information block 140A to utilize the space between the base 120A and the jaw portion 110A, thereby reducing the volume occupied by the dental model 100A. To ensure automatic absorption of the dental model 100A by the information block 140A and reliable information recognition, the information block 140A of the existing dental model 100A is typically larger in size. Consequently, a large amount of photosensitive resin is consumed during the 3D printing process of the dental model 100A.

[0004] In order to reduce the amount of resin consumed in printing the dental model, in the existing technologies such as patent CN220988936U, an information code is set on the lingual side of the anterior tooth area of ​​the base. Although this information code setting method can reduce the amount of resin consumed in printing the dental model, when the dental model is placed on the bearing surface of the carrier tooling, since the information code is placed gingivally and maxillary upwards adjacent to the bearing surface of the carrier tooling, and there is a positioning structure between the dental model and the carrier, it is easy to cause visual recognition interference when the information code is recognized by the visual system, and it will also increase the difficulty of setting up the visual system. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a dental model and an identification system, which aims to solve the problem that the existing dental model sets an information code on the lingual side of the anterior teeth area of ​​the base, which is prone to visual recognition interference when the information code is recognized by the visual system, and also increases the difficulty of setting up the visual system.

[0006] In order to solve the above technical problems, the embodiment of the present invention provides a dental model, comprising: a dental part, a support part for supporting the dental part, and an information code for marking the dental model information; wherein,

[0007] The information code is provided on the side of the buccal or lingual side of the support portion, or a connecting portion is provided between the lingual side surfaces of the two posterior tooth regions of the support portion, and the information code is provided on the first side surface of the connecting portion away from the anterior tooth region;

[0008] The information code is arranged to be inclined gradually away from or adjacent to the support portion in the gingival and maxillary direction.

[0009] The dental model of the present invention sets the information code on the side of the supporting part or the first side of the connecting part, and then there is no need to set up an additional information block of relatively large size. This can reduce the amount of resin consumed in printing the dental model, thereby greatly reducing the printing cost of the dental model; and by setting the information code tilted in the gingival and maxillary direction, not only can visual recognition interference be prevented when the information code is recognized by the visual system, but also the layout of the visual system can be made more convenient and flexible.

[0010] Preferably, an information code support portion is provided on a side surface of the support portion or on the first side surface of the connecting portion, the information code support portion having an inclined surface, and the information code is provided on the inclined surface. By providing the information code on the inclined surface of the information code support portion, an inclined setting of the information code is achieved. Providing the information code support portion on the dental model facilitates forming a relatively regular inclined surface on the dental model.

[0011] Preferably, the difference in height between the end of the inclined surface adjacent to the jaw portion and the end distal thereto, in the direction from the buccal side to the lingual side, is 1.5 mm to 3 mm. By optimizing the range of the difference in height between the two ends of the inclined surface, the information code has a more appropriate tilt angle, thereby preventing visual recognition interference and facilitating the deployment of the visual system.

[0012] Preferably, the information code is directly protruded on the side surface of the support portion or on the first side surface of the connecting portion, wherein the difference in protrusion height between the end of the information code adjacent to the maxillary portion and the end away from the maxillary portion in the direction from the buccal side to the lingual side is 1.5mm to 3mm. The information code is set as a positive structure, and the protrusion height of the information code is set to be gradually changed in the gingival and maxillary direction to achieve the tilt setting of the information code. The positive structure increases the shadow effect of the information code, which is more conducive to subsequent accurate recognition; and by optimizing the value range of the protrusion height difference between the two ends of the information code, the information code has a more appropriate tilt angle, which is conducive to preventing visual recognition interference and is more convenient for the layout of the visual system.

[0013] Preferably, the information code includes multiple character codes, and the protrusion height difference between the two ends of at least two of the character codes is unequal. The tilt angles of the multiple character codes are not identical. Thus, the tilt angle of each character code can be set according to actual conditions to better prevent visual recognition interference. A larger tilt angle can also be set for character codes that are difficult to recognize.

[0014] Preferably, the information code includes any one or a combination of the following: character code, QR code, barcode, graphic. Providing multiple forms of information code makes the implementation of the information code more diverse and facilitates the selection of different implementation methods according to actual applications, making it applicable to more application scenarios.

[0015] Preferably, the protruding height of the information code increases or decreases gradually from left to right. The information code is also tilted in the left and right directions, which can also prevent visual recognition interference and make the layout of the visual system more convenient and flexible.

[0016] Preferably, the information code is tilted at an angle of 15° to 75° relative to the bottom surface of the support portion away from the maxillofacial portion. The information code is tilted at an angle of 15° to 75° in the gingival-maxillary direction. Optimizing the range of the information code's tilt angle helps prevent visual recognition interference and facilitates the deployment of the visual system.

[0017] Preferably, the height of the support portion in the gingival and maxillary direction is 2mm-8mm; the height of the information code in the gingival and maxillary direction is 1 / 2-3 / 4 times the height of the support portion in the gingival and maxillary direction. By optimizing the range of values ​​for the heights of the support portion and the information code, it is ensured that the support portion has a sufficient height dimension to facilitate the formation of the information code on the support portion, and that the information code has a sufficient height dimension to facilitate identification of the information code after the dental model is printed.

[0018] Preferably, the information code is vertically protruded from the side surface of the corresponding support portion or the first side surface of the connecting portion. The information code is set as a positive structure, which increases the shadow effect of the information code and is more conducive to subsequent accurate recognition.

[0019] Preferably, the information code is provided on the lingual side surface of the anterior region of the support portion. The lingual side surface of the anterior region of the support portion is generally not provided with other information markings and is generally not tilted. The gum line of the lingual side surface of the anterior region of the support portion is higher, thereby facilitating the arrangement and printing of the information code on the lingual side surface of the anterior region of the support portion.

[0020] Preferably, the lingual side of the left and / or right posterior tooth region of the support portion is provided with a positioning rod extending toward the opposite posterior tooth region. The positioning rod is provided with a first positioning structure, which is used to form a positioning fit with a second positioning structure on the carrier tooling. The positioning fit between the first and second positioning structures can achieve the installation and positioning of the dental model on the carrier tooling, and the positioning rod can ensure the stability of the dental model during the hot pressing process, making the dental model less likely to deform.

[0021] In order to achieve the above object, the present invention further provides an identification system, comprising:

[0022] A carrier tool, the carrier tool having a bearing surface, the bearing surface being used to bear the dental model;

[0023] A visual component, wherein the visual component is tilted relative to the bearing surface so that the lens of the visual component faces the information code of the dental model;

[0024] A light source is used to emit light toward the dental model.

[0025] The recognition system of the present invention carries the dental model through a carrier tooling, and the lens of the visual component faces the information code of the dental model to capture the image of the information code. The light source can illuminate the information code to increase the brightness of the information code, so that the visual component can recognize it more accurately. Among them, since the information code is tilted in the gingival and maxillary direction, it can not only prevent visual recognition interference, but also make the layout of the visual component more convenient and flexible.

[0026] Preferably, the optical axis of the visual component is perpendicular to the surface of the information code facing the visual component, so that visual recognition interference is less likely to occur when the visual component recognizes the information code.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The utility model provides a dental model, which is used for forming a shell-shaped dental appliance by hot pressing a membrane. Figure 2 and Figure 3 The first embodiment of the dental model provided by the utility model is shown.

[0046] See also Figure 2 and Figure 3 In the first embodiment, the dental model 100 includes: a dental part 1, a supporting part 2 for supporting the dental part 1, and an information code 3 for marking information of the dental model 100; wherein, the information code 3 is arranged on the side of the labial and buccal side A or the lingual side B of the supporting part 2, and the information code 3 is arranged to be gradually inclined in the gingival and maxillary direction toward a direction away from or adjacent to the supporting part 2.

[0047] Specifically, the terms "anterior" and "posterior" are defined based on the tooth classification in the second edition of "Introduction to Stomatology," published by Peking University Medical Press, pages 36-38. The posterior region includes premolars and molars, represented by teeth 4-8 using the FDI notation. The anterior region, represented by teeth 1-3 using the FDI notation, includes the central incisor, lateral incisor, and canine.

[0048] The maxillary portion 1 is mounted on the support portion 2. The anterior region of the support portion 2 is the portion of the support portion 2 used to support the anterior teeth of the maxillary portion 1, while the posterior region of the support portion 2 is the portion of the support portion 2 used to support the posterior teeth of the maxillary portion 1. The support portion 2 is generally U-shaped, having an anterior region and two spaced-apart posterior regions. The gingival-maxillary direction is defined as the up-down direction, with the maxillary portion 1 positioned above the support portion 2. The spacing between the two posterior regions of the support portion 2 is also defined as the left-right direction.

[0049] An information code 3 is provided on at least one of the labial side surface of the anterior teeth area of ​​the support part 2, the lingual side surface of the anterior teeth area of ​​the support part 2, the buccal side surface of the posterior teeth area of ​​the support part 2, and the lingual side surface of the posterior teeth area of ​​the support part 2. By setting the information code 3 on the side surface of the support part 2, there is no need to set an additional information block of a relatively large size. This can reduce the amount of resin consumed in printing the dental model 100, thereby greatly reducing the printing cost of the dental model 100.

[0050] In addition, the information code 3 is arranged to be gradually inclined in the gingival and maxillary direction away from or adjacent to the support part 2, that is, the lower end of the surface of the information code 3 away from the support part 2 (that is, the surface of the information code 3 for visual identification) is upward or the upper end of the surface of the information code 3 away from the support part 2 is inclined downward. This not only prevents visual recognition interference when the information code 3 is identified by the visual system, but also makes the layout of the visual system more convenient and flexible.

[0051] The dental model 100 of the present invention sets the information code 3 on the side of the support part 2, and then there is no need to set up an additional information block of relatively large size. This can reduce the amount of resin consumed in printing the dental model 100, thereby greatly reducing the printing cost of the dental model 100; and by setting the information code 3 tilted in the gingival and maxillary direction, not only can visual recognition interference be prevented when the information code 3 is recognized by the visual system, but also the layout of the visual system can be made more convenient and flexible.

[0052] The side of the support portion 2 is provided with an information code 3. The specific setting style of the information code 3 can be set according to the actual application. Figure 2 and Figure 3 In the first embodiment, the information code 3 includes any one or a combination of the following: a character code 31, a QR code, a barcode, or a graphic. Providing multiple forms of the information code 3 enriches the implementation of the information code 3 and facilitates selection of different implementation methods based on actual applications, making it applicable to a wider range of application scenarios.

[0053] Information code 3 can be positive or negative structure, optional, please refer to Figure 2 and Figure 3 In the first embodiment, the information code 3 is vertically protruded from the side of the corresponding support portion 2. That is, the information code 3 is a positive structure. The positive structure increases the shadow effect of the information code, which is more conducive to subsequent accurate recognition.

[0054] The height of the information code 3 in the gum and jaw direction can be set according to the actual application, and the height of the information code 3 in the gum and jaw direction is usually related to the height of the support part 2 in the gum and jaw direction. Figure 2 and Figure 3 In the first embodiment, the height dimension of the support portion 2 in the gingival and maxillary direction is 2mm-8mm; the height dimension of the information code 3 in the gingival and maxillary direction is 1 / 2-3 / 4 times the height dimension of the support portion 2 in the gingival and maxillary direction. By optimizing the value range of the height dimensions of the support portion 2 and the information code 3, it is ensured that the support portion 2 has a sufficient height dimension to facilitate the formation of the information code 3 on the support portion 2, and it is ensured that the information code 3 has a sufficient height dimension to facilitate the identification of the information code 3 after the dental model 100 is printed. The height dimension of the support portion 2 in the gingival and maxillary direction is set to be greater than 2mm to facilitate the formation of the information code 3 on the support portion 2; and the height dimension of the support portion 2 in the gingival and maxillary direction is set to be less than 8mm in order to reduce the amount of resin consumed in printing the dental model 100. Similarly, setting the height dimension of the information code 3 in the gingival and maxillary direction to be greater than 1 / 2 times the height dimension of the support part 2 in the gingival and maxillary direction can ensure that the information code 3 has a sufficient height dimension to facilitate the identification of the information code 3 after the dental model 100 is printed; and setting the height dimension of the information code 3 in the gingival and maxillary direction to be less than 3 / 4 times the height dimension of the support part 2 in the gingival and maxillary direction can reduce the processing amount of the information code 3.

[0055] As described above, the information code 3 may be provided on at least one of the labial side of the anterior teeth area of ​​the support portion 2, the lingual side of the anterior teeth area of ​​the support portion 2, the buccal side of the posterior teeth area of ​​the support portion 2, and the lingual side of the posterior teeth area of ​​the support portion 2. Figure 2 and Figure 3 In the first embodiment, the information code 3 is provided on the lingual side of the anterior region 22 of the support portion 2. The lingual side of the anterior region 22 of the support portion 2 is generally not provided with other information markings and is generally not tilted. The gum line of the lingual side of the anterior region 22 of the support portion 2 is higher, making it easier to arrange and print the information code 3 on the lingual side of the anterior region 22 of the support portion 2.

[0056] As described above, the lower end of the surface of the information code 3 away from the support portion 2 is upward or the upper end of the surface of the information code 3 away from the support portion 2 is tilted downward. There are many specific ways to achieve the tilted surface of the information code 3 away from the support portion 2. Figure 2 and Figure 3 In the first embodiment, an information code supporting portion 5 is provided on the side surface of the supporting portion 2 . The information code supporting portion 5 has an inclined surface 51 , and the information code 3 is provided on the inclined surface 51 .

[0057] Specifically, the information code 3 is arranged on the inclined surface 51 of the information code support portion 5 to achieve an inclined setting of the information code 3. Providing the information code support portion 5 on the dental model 100 facilitates forming a relatively regular inclined surface on the dental model 100. Furthermore, when the inclined surface 51 is an upwardly inclined surface at its lower end, it helps ensure the printing quality and structural strength of the support portion 2 at the information code support portion 5.

[0058] There are many ways to specifically arrange the information code support portion 5 on the side of the support portion 2. For example, please refer to Figure 2 and Figure 3 In the first embodiment, the information code support portion 5 is a boss protruding from the side of the support portion 2. The boss's height gradually increases or decreases from the end adjacent to the jaw portion 1 to the end away from the jaw portion 1 in the direction from the buccal side A to the lingual side B, thereby forming an inclined surface 51 on the information code support portion 5. Providing the boss on the side of the support portion 2 as the information code support portion 5 can enhance the structural strength of the support portion 2.

[0059] Optionally, in other embodiments, the information code supporting portion 5 may also be a groove (not shown) provided on the side surface of the supporting portion 2, and the inclined surface 51 is the bottom wall of the groove.

[0060] Optionally, see Figure 2 and Figure 3 In the first embodiment, the height difference between the end of the inclined surface 51 adjacent to the maxillary portion 1 and the end away from the maxillary portion 1 in the direction from the buccal side A to the lingual side B is 1.5 mm to 3 mm.

[0061] Specifically, the difference in protrusion height L between the end of the inclined surface 51 adjacent to the maxillary portion 1 and the end remote from the maxillary portion 1 in the direction from the buccal side A to the lingual side B is equal to L. The information code 3 is tilted in the gingival-maxillary direction, so that the information code 3 has an inclination angle. The inclination angle of the information code 3 is the angle α between the surface of the information code 3 remote from the support portion 2 and the bottom surface of the support portion 2 remote from the maxillary portion 1. The difference in protrusion height L between the upper and lower ends of the inclined surface 51 is related to the inclination angle α of the information code 3. By optimizing the range of the difference in protrusion height between the two ends of the inclined surface 51, the information code 3 can have a more appropriate inclination angle, which helps prevent visual recognition interference and facilitates the layout of the visual system. Setting the protruding height difference L between the upper and lower ends of the inclined surface 51 to be greater than 1.5mm can make the information code 3 have a more suitable inclination angle, which is beneficial to prevent visual recognition interference and is more convenient for arranging the visual system; and setting the protruding height difference L between the upper and lower ends of the inclined surface 51 to be less than 3mm can avoid the inclination angle α of the information code 3 being too large, which is not only not conducive to the processing and molding of the information code support part 5, but also increases the amount of resin consumed in printing the dental model 100.

[0062] In addition to setting the information code 3 on the inclined surface 51 to achieve the inclined setting of the information code 3, optionally, refer to Figure 7 In the fifth embodiment, the information code 3 is directly protruded on the side of the support part 2, wherein the protruding height difference between the end of the information code 3 adjacent to the maxillary part 1 and the end away from the maxillary part 1 in the direction from the labial side A to the lingual side B is 1.5mm to 3mm.

[0063] Specifically, the information code 3 is set as a positive structure, and the protruding height of the information code 3 is set to be gradually changed in the gingival and maxillary direction, so that there is a protruding height difference between the upper end and the lower end of the information code 3 in the direction from the labial and buccal side A to the lingual side B, thereby realizing the tilt setting of the information code 3, and the positive structure increases the shadow effect of the information code 3, which is more conducive to subsequent accurate recognition. At the same time, by optimizing the value range of the protruding height difference between the two ends of the information code 3, the information code 3 has a more suitable tilt angle, which is conducive to preventing visual recognition interference and is more convenient for the layout of the visual system. Setting the protruding height difference between the two ends of the information code 3 to be greater than 1.5mm can enable the information code 3 to have a more suitable tilt angle, which is conducive to preventing visual recognition interference and is more convenient for the layout of the visual system; and setting the protruding height difference between the two ends of the information code 3 to be less than 3mm can avoid the tilt angle α of the information code 3 being too large, which is not only not conducive to the processing and molding of the information code 3, but also increases the amount of resin consumed in printing the dental model 100.

[0064] The information code 3 typically includes multiple character codes 31. There is a difference in protrusion height between the two ends of the information code 3, i.e., each character code 31 has a difference in protrusion height. The protrusion height differences between the two ends of the multiple character codes 31 can be all equal, not completely equal, or unequal. Alternatively, in other embodiments, the information code 3 includes multiple character codes 31, and the protrusion height differences between the two ends of at least two character codes 31 are unequal.

[0065] Specifically, the height difference of the protrusions at both ends of at least two character codes 31 is not equal, that is, the inclination angles of multiple character codes 31 are not exactly the same. In this way, the size of the inclination angle of each character code 31 can be set separately according to actual conditions, so as to better prevent visual recognition interference, and a larger inclination angle can also be set separately for character codes 31 that are difficult to recognize.

[0066] By setting the information code 3 in an up and down tilt direction, visual recognition interference can be prevented, and the tilt angle of the information code 3 is set according to the actual application. Figure 2 and Figure 3In the first embodiment, the inclination angle of the information code 3 relative to the bottom surface of the support portion 2 away from the maxillary portion 1 is 15° to 75°. In this way, by optimizing the value range of the inclination angle α of the information code 3, it is beneficial to prevent visual recognition interference and it is also more convenient to arrange the visual system. Setting the inclination angle α of the information code 3 to be greater than 15° can make the information code 3 have a more suitable inclination angle, which is beneficial to prevent visual recognition interference and it is also more convenient to arrange the visual system; and setting the inclination angle α of the information code 3 to be less than 75° can avoid the inclination angle α of the information code 3 being too large, which is not only not conducive to the processing and molding at the information code 3, but also increases the amount of resin consumed in printing the maxillary model 100.

[0067] Setting the information code 3 at an angle in the vertical direction can prevent visual recognition interference. It is understood that setting the information code 3 at an angle in the left and right directions can also prevent visual recognition interference. For example, if the protrusion height of the information code 3 gradually increases or decreases from left to right, setting the information code 3 at an angle in the left and right directions can also prevent visual recognition interference, making the layout of the visual system more convenient and flexible.

[0068] When visually identifying the information code 3 of the dental model 100, the dental model 100 is usually placed on the carrier tool 200. In order to realize the installation and positioning of the dental model 100 on the carrier tool 200, optionally, refer to Figure 5 and Figure 11 In the third embodiment, the lingual side of the left and / or right posterior tooth area 21 of the support portion 2 is provided with a positioning rod 6 extending toward the opposite posterior tooth area 21, and a first positioning structure 61 is provided on the positioning rod 6. The first positioning structure 61 is used to match the second positioning structure 220 on the carrier tooling 200 to form a positioning fit.

[0069] Specifically, one of the first positioning structure 61 and the second positioning structure 220 is a positioning post, and the other is a positioning hole. When the dental model 100 is placed on the carrier 200, the positioning post extends into the positioning hole, allowing the positioning post and the positioning hole to match each other in a concave and convex manner to form a positioning fit. This positioning fit between the first positioning structure 61 and the second positioning structure 220 allows the dental model 100 to be installed and positioned on the carrier 200. Furthermore, the positioning rod 6 ensures the stability of the dental model 100 during the hot pressing process, preventing deformation.

[0070] The first positioning structure 61 can be a positioning column or a positioning hole. Figure 5 In the third embodiment, the first positioning structure 61 is a positioning hole, which can further reduce the amount of resin consumed in printing the dental model 100.

[0071] A positioning rod 6 is provided on the lingual side surface of the posterior tooth area 21 of the support part 2. The positioning rod 6 may be provided on the lingual side surface of only the left posterior tooth area 21 of the support part 2, or on the lingual side surface of only the right posterior tooth area 21 of the support part 2, or on the lingual side surfaces of both the left and right posterior tooth areas 21 of the support part 2.

[0072] Optionally, see Figure 6 In the fourth embodiment, a positioning rod 6 is provided on the lingual side of the left posterior region 21 of the support portion 2, while no positioning rod 6 is provided on the lingual side of the right posterior region 21 of the support portion 2. Providing positioning rods 6 only on the lingual side of the posterior region 21 of one support portion 2 can reduce the amount of resin consumed in printing the dental model 100.

[0073] Optionally, see Figure 5 In the third embodiment, positioning rods 6 are provided on the lingual side of the left and right posterior tooth areas 21 of the support portion 2. This helps improve the positioning accuracy between the dental model 100 and the carrier tool 200, and also improves the structural strength of the left and right posterior tooth areas 21 of the support portion 2 through the positioning rods 6.

[0074] The positioning rod 6 on the lingual side of the left posterior tooth area 21 of the support part 2 and the positioning rod 6 on the lingual side of the right posterior tooth area 21 of the support part 2 can be connected or disconnected.

[0075] Optionally, see Figure 4 In the second embodiment, the positioning rod 6 on the lingual side of the left posterior tooth area 21 of the support part 2 is connected to the positioning rod 6 on the lingual side of the right posterior tooth area 21 of the support part 2 to form a strip structure. This can further improve the structural strength of the dental model 100.

[0076] Optionally, see Figure 5 In the third embodiment, the positioning rods 6 on the lingual side of the left posterior tooth area 21 of the support portion 2 and the positioning rods 6 on the lingual side of the right posterior tooth area 21 of the support portion 2 are spaced apart in the left-right direction at their respective ends. This helps reduce the amount of resin consumed in printing the dental model 100.

[0077] The utility model provides a dental model, which is used for forming a shell-shaped dental appliance by hot pressing a membrane. Figure 8 The sixth embodiment of the dental model provided by the present invention is shown.

[0078] See also Figure 8In the sixth embodiment, the dental model 100 includes: a dental part 1, a supporting part 2 for supporting the dental part 1, and an information code 3 for marking information of the dental model 100; wherein, a connecting part 4 is provided between the lingual side surfaces of the two posterior tooth areas 21 of the supporting part 2, and the information code 3 is provided on the first side surface 41 of the connecting part 4 away from the anterior tooth area 22; the information code 3 is provided in a gingival-maxillary direction and is gradually inclined in a direction away from or adjacent to the supporting part 2.

[0079] Specifically, unlike the first to fourth embodiments, a connecting portion 4 is provided between the lingual side surfaces of the two posterior tooth regions 21 of the support portion 2, and the information code 3 is provided on a first side surface 41 of the connecting portion 4 away from the anterior tooth region 22. The information code 3 is arranged to be gradually inclined in the gingival-maxillary direction away from or adjacent to the support portion 2, that is, the lower end of the surface of the information code 3 away from the connecting portion 4 (that is, the surface of the information code 3 for visual identification) is inclined upward, or the upper end of the surface of the information code 3 away from the connecting portion 4 is inclined downward. This not only prevents visual recognition interference when the information code 3 is recognized by the visual system, but also makes the layout of the visual system more convenient and flexible.

[0080] The dental model 100 of the present invention sets the information code 3 on the first side surface 41 of the connecting portion 4, thereby eliminating the need for additional information blocks of relatively large size. This can reduce the amount of resin consumed in printing the dental model 100, thereby significantly reducing the printing cost of the dental model 100. Furthermore, by setting the information code 3 tilted in the gingival and maxillary direction, not only can visual recognition interference be prevented when the visual system recognizes the information code 3, but the layout of the visual system can also become more convenient and flexible.

[0081] Optionally, see Figure 8 In the sixth embodiment, what is different from the first to fourth embodiments is that the information code supporting portion 5 is disposed on the first side surface 41 of the connecting portion 4 .

[0082] Specifically, the information code 3 is tilted by setting it on the inclined surface 51 of the information code support part 5, and setting the information code support part 5 on the dental model 100 is conducive to forming a more regular inclined surface on the dental model 100.

[0083] When visually identifying the information code 3 of the dental model 100, the dental model 100 is usually placed on the carrier tool 200. In order to realize the installation and positioning of the dental model 100 on the carrier tool 200, optionally, refer to Figure 8 In the sixth embodiment, a first positioning structure 61 is provided on the connecting portion 4 , and the first positioning structure 61 is used to match the second positioning structure 220 on the carrier tooling 200 in a concave-convex manner to form a positioning fit.

[0084] In the case where a connecting part 4 is provided on the dental model 100, in addition to being provided on the connecting part 4, the first positioning structure 61 can also be provided with a positioning rod 6 in the second embodiment or the third embodiment on the lingual side of the left and / or right posterior tooth area 21 of the support part 2, and the first positioning structure 61 is provided on the positioning rod 6.

[0085] The utility model provides an identification system. Figures 9 to 11 An embodiment of the identification system provided by the present utility model is shown.

[0086] See also Figures 9 to 11 In the seventh embodiment, the recognition system 1000 includes a carrier tooling 200, a visual component 300 and a light source 400. The carrier tooling 200 has a carrying surface 210, and the carrying surface 210 is used to carry the above-mentioned dental model 100; the visual component 300 is tilted relative to the carrying surface 210 so that the lens 310 of the visual component 300 is facing the information code 3 of the dental model 100; the light source 400 is used to emit light toward the dental model 100.

[0087] Specifically, the bearing surface 210 is usually the upper surface of the carrier tooling 200. When the lens 310 of the visual component 300 is located on the upper side of the dental model 100, the information code 3 is gradually tilted from top to bottom in the direction away from the support part 2; when the lens 310 of the visual component 300 is located on the lower side of the dental model 100, the information code 3 is gradually tilted from top to bottom in the direction adjacent to the support part 2. This not only prevents visual recognition interference, but also makes the layout of the visual component 300 more convenient and flexible.

[0088] The light source 400 can illuminate the information code 3 to increase its brightness, allowing the visual component 300 to more accurately recognize it. The light source 400 and the visual component 300 can be arranged on the same horizontal side of the carrier tooling 200, or the light source 400 and the visual component 300 can be arranged on opposite sides of the carrier tooling 200.

[0089] Optionally, see Figures 9 to 11 In the seventh embodiment, the light source 400 is arranged in a ring shape and is mounted outside the end of the vision component 300 close to the lens 310. In this way, the arrangement of the light source 400 and the vision component 300 is relatively compact, and there is no interference between the light source 400 and the vision component 300.

[0090] The recognition system 1000 of the present invention carries the dental model 100 through the carrier tooling 200, and the lens 310 of the visual component 300 faces the information code 3 of the dental model 100 to capture the image of the information code 3. The light source 400 can illuminate the information code 3 to enhance the brightness of the information code 3, so that the visual component 300 can recognize it more accurately. In particular, since the information code 3 is tilted in the gingival-maxillary direction, it can not only prevent visual recognition interference, but also make the layout of the visual component 300 more convenient and flexible.

[0091] The optical axis of the visual component 300 is usually perpendicular or approximately perpendicular to the surface of the information code 3 facing the visual component 300. Figures 9 to 11 In the seventh embodiment, the optical axis of the visual component 300 is perpendicular to the surface of the information code 3 facing the visual component 300. In this way, visual recognition interference is less likely to occur when the visual component 300 recognizes the information code 3.

[0092] Optionally, see Figures 9 to 11 In the seventh embodiment, the second positioning structure 220 is provided on the bearing surface 210 and matches the first positioning structure 61 on the dental model 100 in a concave-convex manner to form a positioning fit. In this way, the positioning fit between the first positioning structure 61 and the second positioning structure 220 can achieve the installation and positioning of the dental model 100 on the carrier tool 200.

[0093] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
