Description

Technical Field

[0001] The present invention relates to the technical field of zircon disc matching, and in particular to a zircon disc matching method and system for improving utilization rate. Background Art

[0002] Zircon discs are widely used in dental restorations, such as crowns, bridges, and implant abutments. Dental restorations made with zircon discs are not only durable but also natural and lifelike, blending seamlessly with the patient's oral environment and improving both masticatory function and aesthetics.

[0003] The production process involves importing a 3D tooth model into a high-precision machine tool. The machine then uses the model's parameters to cut the tooth onto a zircon disc. Once the tooth is cut, the disc is removed, leaving a cavity in the area corresponding to the tooth, allowing the remaining area to continue processing.

[0004] To improve the utilization rate of zircon disks, related technologies have established a database to collect data on surplus zircon disks worth processing and record the workable area of ​​the remaining zircon disks. When additional teeth need to be fabricated, the area occupied by the tooth's 3D model is obtained and the corresponding remaining zircon disk is searched in the database, allowing the remaining zircon disks to be utilized.

[0005] However, when cutting zircon discs, the machine tool's internal fixtures must hold the disc's edge (i.e., the clamping area). This causes a portion of the disc's edge to be occupied by the fixture, making the clamped area unusable for cutting. Current matching methods also ignore this area. Therefore, how to combine the remaining machinable area of ​​the zircon disc with the edge to achieve a larger matching area is a key challenge. Summary of the Invention

[0006] The object of the present invention is to provide a zircon disk matching method and system with improved utilization, so as to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, one of the objectives of the present invention is to provide a zircon disk matching method for improving utilization, comprising the following method steps: S1. Creating a zircon disk feature database, collecting the machinable area of ​​each remaining zircon disk, and marking the remaining zircon disks as zircon disks to be optimized and ordinary zircon disks based on the positional relationship of the machinable areas, wherein the machinable area of ​​the zircon disk to be optimized is at the edge of the zircon disk to be optimized; S2. Matching a plurality of ordinary zircon discs of corresponding weights to the zircon disc to be optimized, and collecting the stability of the zircon disc to be optimized in different clamping modes. When the stability meets a preset value, marking the clamping area corresponding to the clamping mode as the optimal clamping area of ​​the zircon disc to be optimized; S3, obtaining the number of regions of the zircon disk to be optimized that meet the optimal clamping area, selectively combining the machinable area and the clamping area according to the number of regions, and generating the final clamping point and the final machining area; S4. Establish a data matching platform to match the corresponding remaining zircon disk and the optimal clamping area according to the occupied area of ​​the tooth model.

[0008] As a further improvement of the present technical solution, the steps of marking the remaining zircon disks in S1 are as follows: S1.1. Build a three-dimensional model for each remaining zircon disk; S1.2. Obtain parameter information of the three-dimensional model, and identify the blank area of ​​the remaining zircon disk based on the parameter information; S1.3. Set the area threshold. When the blank area is larger than the area threshold, mark the blank area as a processable area. S1.4. Based on the parameter information in S1.2, the position of the clamping area is obtained. When the machinable area is adjacent to the clamping area, the corresponding zircon disk is marked as a zircon disk to be optimized; when the machinable area is not adjacent to the clamping area, the corresponding zircon disk is marked as an ordinary zircon disk.

[0009] As a further improvement of the present technical solution, the method steps for matching the zircon disc to be optimized with a plurality of ordinary zircon discs of corresponding weight in S2 are as follows: S2.1. Obtaining the weight information of the zircon disk to be optimized and the weight information of ordinary zircon disks ; S2.2. Calculate the weight difference between the optimized zircon disk and the ordinary zircon disk ; S2.3. Setting the judgment threshold , when the weight difference ≤ judgment threshold When optimizing, the zircon disk and the corresponding ordinary zircon disk are bound to the collection group.

[0010] As a further improvement of this technical solution, the method steps for marking the optimal clamping area in S2 are as follows: S2.4. Identify the number of common zircon disks in the collection group and create a different clamping area for each common zircon disk; S2.5. Establish a human-computer interaction platform. When ordinary zircon discs in the collection group need to be processed, the corresponding clamping area of ​​the ordinary zircon discs will be pushed to the staff; S2.6. Obtain a finished tooth product made from a common zircon plate and compare the finished tooth product with the corresponding three-dimensional model to obtain similarity information. ; S2.7. Setting the Similarity Threshold , when the similarity information ≥Similarity threshold , obtaining a common zircon disk corresponding to the finished tooth product; S2.8. Obtain the clamping area corresponding to the ordinary zircon disk in S2.7, and mark the smallest clamping area among multiple clamping areas as the optimal clamping area.

[0011] As a further improvement of the present technical solution, the method for creating different clamping areas in S2.4 is: gradually reducing the clamping area according to the processing sequence of the ordinary zircon disk.

[0012] As a further improvement of this technical solution, the method steps for generating the final processing area in S3 are as follows: S3.1. Obtain the clamping area of ​​the edge of the zircon disk to be optimized and the number of clamping areas; S3.2. When the area of ​​the clamping area is larger than the optimal clamping area, mark the clamping area; S3.3. When the number of marked clamping areas is greater than or equal to two, the clamping areas of non-adjacent machinable areas are marked as final clamping points, and the clamping areas of adjacent machinable areas are combined to generate the final machining area.

[0013] As a further improvement of this technical solution, the method steps for establishing the data matching platform in S4 are as follows: S4.1. Obtaining the occupied area of ​​the tooth model ; S4.2. Obtaining the area of ​​the machinable region of a common zircon disk , get the area of ​​the final processing area of ​​the zircon disk to be optimized , where the area of ​​the machinable area and the area of ​​the final processing area Larger than the occupied area ; S4.3. Setting the matching threshold , when the area of ​​the machinable area - Occupied area ≤ matching threshold When the tooth model is matched with the corresponding ordinary zircon disk; when the area of ​​the final processing area - Occupied area ≤ matching threshold When the tooth model is matched with the corresponding zircon disk to be optimized; S4.4. When the tooth model matches the corresponding zircon disk to be optimized, the final clamping point corresponding to the zircon disk to be optimized is pushed to the staff through the human-computer interaction platform in S2.5.

[0014] A second object of the present invention is to provide a system for a zircon disk matching method for improving utilization, comprising a zircon disk feature acquisition module, a stability analysis module, a regional combination decision module, and a zircon disk comprehensive matching module, wherein: The zircon disk feature acquisition module creates a zircon disk feature database, collects the machinable area of ​​each remaining zircon disk, and marks the remaining zircon disks as zircon disks to be optimized and ordinary zircon disks according to the positional relationship of the machinable areas, wherein the machinable area of ​​the zircon disk to be optimized is at the edge of the zircon disk to be optimized; The stability analysis module matches the zircon disc to be optimized with multiple ordinary zircon discs of corresponding weight, and collects the stability of the zircon disc to be optimized when facing different clamping methods. When the stability meets the preset value, the clamping area corresponding to the clamping method is marked as the optimal clamping area of ​​the zircon disc to be optimized; The region combination decision module obtains the number of regions of the zircon disk to be optimized that meet the optimal clamping area, selectively combines the machinable region and the clamping region according to the number of regions, and generates a final clamping point and a final processing region; The zircon disk comprehensive matching module establishes a data matching platform to match the corresponding remaining zircon disks and the optimal clamping area according to the occupied area of ​​the tooth model.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the zircon disk matching method and system for improving utilization, the optimal clamping area is obtained by analyzing the adjacent relationship between the machinable area and the clamping area in combination with the weight of the zircon disk, and other clampable positions of the zircon disk are identified based on the optimal clamping area, thereby obtaining multiple clampable positions. The change of the clamping position is utilized to enable the machinable area to be combined with part of the clamping area, thereby obtaining a higher matching area and improving the utilization of the zircon disk.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of the present invention, “plurality” means two or more than two, unless otherwise clearly defined.

[0020] See also Figures 1-8 As shown, one of the purposes of the present invention is to provide a zircon disk matching method for improving utilization, comprising the following method steps: S1. Creating a zircon disk feature database, collecting the machinable area of ​​each remaining zircon disk, and marking the remaining zircon disks as zircon disks to be optimized and ordinary zircon disks based on the positional relationship of the machinable areas, wherein the machinable area of ​​the zircon disk to be optimized is at the edge of the zircon disk to be optimized; S2. Matching a plurality of ordinary zircon discs of corresponding weights to the zircon disc to be optimized, and collecting the stability of the zircon disc to be optimized under different clamping methods. When the stability meets the preset value, marking the clamping area corresponding to the clamping method as the optimal clamping area of ​​the zircon disc to be optimized; S3, obtaining the number of regions of the zircon disk to be optimized that meet the optimal clamping area, selectively combining the machinable area and the clamping area according to the number of regions, and generating the final clamping point and the final machining area; S4. Establish a data matching platform to match the corresponding remaining zircon disk and the optimal clamping area according to the occupied area of ​​the tooth model.

[0021] The zircon disk matching method of the present invention obtains the optimal clamping area by analyzing the adjacent relationship between the machinable area and the clamping area in combination with the weight of the zircon disk, and identifies other clampable positions of the zircon disk based on the optimal clamping area, thereby obtaining multiple clampable positions. The change of the clamping position is utilized to enable the machinable area to be combined with part of the clamping area, thereby obtaining a higher matching area and improving the utilization rate of the zircon disk.

[0022] Here, the remaining zircon disk refers to the area of ​​the zircon disk that remains after cutting, which can be used later to make finished teeth.

[0023] In addition, the steps for marking the remaining zircon disks in S1 are as follows: S1.1. Build a three-dimensional model for each remaining zircon disk; S1.2. Obtain parameter information of the three-dimensional model, and identify the blank area of ​​the remaining zircon disk based on the parameter information; S1.3. Set the area threshold. When the blank area is larger than the area threshold, mark the blank area as a processable area. S1.4. Based on the parameter information in S1.2, the position of the clamping area is obtained. When the machinable area is adjacent to the clamping area, the corresponding zircon disk is marked as a zircon disk to be optimized; when the machinable area is not adjacent to the clamping area, the corresponding zircon disk is marked as an ordinary zircon disk.

[0024] It should be understood that the surface of a complete zircon disk is entirely blank, but the remaining zircon disk may have multiple holes on its surface due to machining and cutting. Therefore, the remaining zircon disk surface, excluding the holes, is blank. Blank areas may be separated by holes, so there may be multiple blank areas. Moreover, some blank areas are located between multiple holes, resulting in the inability to process these blank areas if the area is small. Therefore, a region threshold is set to filter the blank area of ​​the blank area, and only blank areas larger than the region threshold can be processed.

[0025] For example, if there are three blank areas on the surface of a remaining zircon disk, with blank areas of 10 square millimeters, 30 square millimeters, and 50 square millimeters respectively, assuming the area threshold is 25 square millimeters, calculations show that the blank areas corresponding to 30 square millimeters and 50 square millimeters are machinable areas.

[0026] After obtaining the machinable area, the remaining zircon disks are marked accordingly by obtaining the location of the machinable area. For example, the machinable area of ​​the remaining zircon disk a is adjacent to the clamping area at the edge. The machinable area and the clamping area can be combined into a complete area (i.e., the final machinable area, which will be described in detail below). Therefore, the remaining zircon disk a is marked as the zircon disk to be optimized. For another example, the machinable area of ​​the remaining zircon disk b is located in the middle and is not adjacent to the clamping area. This machinable area cannot be combined with the clamping area to form a complete area. Therefore, the remaining zircon disk b is marked as a normal zircon disk.

[0027] Furthermore, the method steps for matching the zircon disc to be optimized with a plurality of ordinary zircon discs of corresponding weight in S2 are as follows: S2.1. Obtaining the weight information of the zircon disk to be optimized and the weight information of ordinary zircon disks ; S2.2. Calculate the weight difference between the optimized zircon disk and the ordinary zircon disk ; S2.3. Setting the judgment threshold , when the weight difference ≤ judgment threshold When optimizing, the zircon disk and the corresponding ordinary zircon disk are bound to the collection group.

[0028] For example, there are two zircon disks to be optimized, named a and b, and six common zircon disks, named a, b, c, d, e, and f, in the database. Assume that the weight of zircon disk a to be optimized is 2kg, and the weight of b is 3kg; the weight of common zircon disk a is 1.9kg, the weight of b is 2kg, the weight of c is 2.1kg, the weight of d is 2.9kg, the weight of e is 3kg, and the weight of f is 3.1kg; Assume that the weight difference is The weight of the zircon disk a to be optimized is 0.2 kg. At this time, the calculation formula of S2.3 shows that the zircon disk a to be optimized is bound to the ordinary zircon disks a, b, and c; the zircon disk b to be optimized is bound to the ordinary zircon disks d, e, and f.

[0029] It should be understood that the machinable areas of the bound ordinary zircon discs are all located in the middle part and cannot be combined with the clamping area. Therefore, the ordinary zircon disc only needs to match the tooth model of the corresponding area according to the area of ​​its own machinable area. The purpose of binding is mainly to test the clamping area. Since a new zircon disc is heavy, a larger clamping area is required to achieve stable clamping of the new zircon disc; and the remaining zircon disc has undergone cutting, resulting in a reduction in weight. Therefore, after the weight is reduced, by reducing the clamping area of ​​the remaining zircon disc, the stability of the remaining zircon disc can also be guaranteed. When the clamping area is reduced, it means that other parts of the clamping area can be combined with the machinable area.

[0030] Furthermore, the steps for marking the optimal clamping area in S2 are as follows: S2.4. Identify the number of common zircon disks in the collection group and create a different clamping area for each common zircon disk; S2.5. Establish a human-computer interaction platform. When ordinary zircon discs in the collection group need to be processed, the corresponding clamping area of ​​the ordinary zircon discs will be pushed to the staff; S2.6. Obtain a finished tooth product made from a common zircon plate and compare the finished tooth product with the corresponding three-dimensional model to obtain similarity information. ; S2.7. Setting the Similarity Threshold , when the similarity information ≥Similarity threshold When the tooth is finished, a common zircon plate corresponding to the finished tooth is obtained; S2.8. Obtain the clamping area corresponding to the ordinary zircon disk in S2.7, and mark the smallest clamping area among multiple clamping areas as the optimal clamping area.

[0031] For example, the collection team has four ordinary zircon disks, namely a, b, c, and d. In this case, four different clamping areas are set, such as 20 square millimeters, 15 square millimeters, 10 square millimeters, and 5 square millimeters. Then, assuming that a three-dimensional model a of a tooth matches the ordinary zircon disk a, the ordinary zircon disk a needs to be processed. When processing the ordinary zircon disk a, the 20 square millimeter clamping requirement is pushed to the staff through the human-computer interaction platform. Then, the information of the finished tooth a obtained through the ordinary zircon disk a is collected, and the finished tooth a is compared with the three-dimensional model a. If the comparison results are consistent, it indicates that the ordinary zircon disk a is in a stable state when facing the 20 square millimeter clamping state.

[0032] Then, when the three-dimensional model b of another tooth is matched with the ordinary zircon plate b, the clamping requirement of 15 square millimeters is pushed to the staff, the information of the finished tooth b is obtained through the ordinary zircon plate b, and the finished tooth a is compared with the three-dimensional model b. If the comparison results are consistent, it indicates that the ordinary zircon plate b is in a stable state when facing the clamping state of 15 square millimeters.

[0033] When another three-dimensional model c of a tooth is matched with the ordinary zircon plate c, the clamping requirement of 10 square millimeters is pushed to the staff, and the information of the finished tooth c is obtained through the ordinary zircon plate c. The finished tooth c is compared with the three-dimensional model c. If the comparison results are consistent, it indicates that the ordinary zircon plate c is in a stable state when facing the clamping state of 10 square millimeters.

[0034] When another tooth's 3D model d matches the ordinary zircon plate d, the 5 square millimeter clamping requirement is pushed to the staff, and the information of the tooth product d obtained through the ordinary zircon plate d is collected. The tooth product d is compared with the 3D model d. If the comparison result is less than the similarity threshold , indicating that the finished tooth product d is not similar to the three-dimensional model d, which means that the ordinary zircon disk d has unstable phenomena such as displacement and shaking when facing the clamping state of 5 square millimeters.

[0035] Then, the smallest one, namely 10 square millimeters, was selected from 20 square millimeters, 15 square millimeters and 10 square millimeters. Since the zircon disk to be optimized and the ordinary zircon disk c were in the same collection group and the weights in the same collection group were similar, the clamping state of 10 square millimeters could also stabilize the zircon disk to be optimized. Therefore, 10 square millimeters was marked as the optimal clamping area of ​​the zircon disk to be optimized.

[0036] It should be understood that when the zircon disc is stably clamped, the finished tooth will be consistent with the shape of the corresponding 3D model. Therefore, if the shape of the finished tooth is inconsistent with the shape of the corresponding 3D model, it indicates that the zircon disc is shaking or shifting.

[0037] It should be noted that after the teeth are cut from the zircon disk, they still need to be manually polished and optimized. Therefore, when the adjustment of the clamping area mentioned above causes some teeth to be inconsistent with the model, this can be solved through manual polishing and optimization.

[0038] Specifically, the method for creating different clamping areas in S2.4 is to gradually reduce the clamping area according to the processing order of the ordinary zircon discs. For example, if there are four ordinary zircon discs in the collection team, four different clamping areas are set at this time, for example, 20 square millimeters, 15 square millimeters, 10 square millimeters, and 5 square millimeters respectively. When one of the ordinary zircon discs is processed first, a clamping area of ​​20 square millimeters is selected first. When the second ordinary zircon disc is processed, a clamping area of ​​15 square millimeters is selected. When the third ordinary zircon disc is processed, a clamping area of ​​10 square millimeters is selected, and so on.

[0039] It should be noted that the clamping area is adjusted based on the clamping area of ​​a new zircon disc. For example, the maximum clamping area of ​​a new zircon disc is 20 square millimeters. Therefore, when setting the clamping area, the area will be gradually reduced based on 20 square millimeters. The amount of area reduction can be adjusted based on actual conditions.

[0040] It should be further explained that the above method is only for obtaining the minimum clamping area (i.e., the optimal clamping area) of the zircon disc to be optimized. Other methods can also be used to obtain the optimal clamping area. For example, some processing equipment records the clamping area corresponding to zircon discs of different weights, and these parameters can be directly obtained from the equipment. Alternatively, relevant data can be obtained through a large AI model.

[0041] In addition, the method steps for generating the final processing area in S3 are as follows: S3.1. Obtain the clamping area of ​​the edge of the zircon disk to be optimized and the number of clamping areas; S3.2. When the area of ​​the clamping area is larger than the optimal clamping area, mark the clamping area; S3.3. When the number of marked clamping areas is greater than or equal to two, the clamping areas of non-adjacent machinable areas are marked as final clamping points, and the clamping areas of adjacent machinable areas are combined to generate the final machining area.

[0042] For example, the outer ring of the zircon disk to be optimized has three clamping areas: a, b, and c. Assume that the area of ​​clamping area a is 10 square millimeters, the area of ​​clamping area b is 15 square millimeters, and the area of ​​clamping area c is 20 square millimeters. Assuming the optimal clamping area is 10 square millimeters, then clamping areas a, b, and c all meet the requirements. This means that the zircon disk to be optimized has three clamping areas.

[0043] Assuming clamping area a is adjacent to the machinable area, while clamping areas b and c are not, clamping areas b and c are marked as the final clamping points. The area of ​​clamping area a is combined with the area of ​​the machinable area to generate the final area. For example, if clamping area a is 10 square millimeters and the machinable area is 50 square millimeters, the final machinable area after combining clamping area a and the machinable area is 60 square millimeters. This allows for larger teeth and improves the utilization of the zircon disc.

[0044] Furthermore, the steps for establishing a data matching platform in S4 are as follows: S4.1. Obtaining the occupied area of ​​the tooth model ; S4.2. Obtaining the area of ​​the machinable region of a common zircon disk , get the area of ​​the final processing area of ​​the zircon disk to be optimized , where the area of ​​the machinable area and the area of ​​the final processing area Larger than the occupied area ; S4.3. Setting the matching threshold , when the area of ​​the machinable area - Occupied area ≤ matching threshold When the tooth model is matched with the corresponding ordinary zircon disk; when the area of ​​the final processing area - Occupied area ≤ matching threshold When the tooth model is matched with the corresponding zircon disk to be optimized; S4.4. When the tooth model matches the corresponding zircon disk to be optimized, the final clamping point corresponding to the zircon disk to be optimized is pushed to the staff through the human-computer interaction platform in S2.5.

[0045] For example, the area occupied by tooth model a The area occupied by tooth model b is 10 square millimeters. Assuming that the area of ​​the processable area of ​​an ordinary zircon disk is The final processing area of ​​the zircon disc to be optimized is 11 square millimeters. is 16 square millimeters. Assuming the matching threshold If the area of ​​the zircon disk is 2 square millimeters, then tooth model a matches the standard zircon disk, while tooth model b matches the zircon disk to be optimized. Furthermore, because the final processing area of ​​the zircon disk to be optimized is a combination of the machinable area and the adjacent clamping area, the clamping area adjacent to the machinable area cannot be clamped during cutting. Therefore, by pushing the final clamping point to the staff, they can clamp the corresponding position, thus realizing the utilization of the final processing area.

[0046] A second object of the present invention is to provide a system for a zircon disk matching method for improving utilization, comprising a zircon disk feature acquisition module 100, a stability analysis module 200, a regional combination decision module 300, and a zircon disk comprehensive matching module 400, wherein: The zircon disk feature collection module 100 creates a zircon disk feature database, collects the machinable area of ​​each remaining zircon disk, and marks the remaining zircon disks as zircon disks to be optimized and ordinary zircon disks based on the positional relationship of the machinable areas. The machinable area of ​​the zircon disk to be optimized is at the edge of the zircon disk to be optimized. The stability analysis module 200 matches the zircon disc to be optimized with multiple ordinary zircon discs of corresponding weights and collects the stability of the zircon disc to be optimized when facing different clamping methods. When the stability meets the preset value, the clamping area corresponding to the clamping method is marked as the optimal clamping area of ​​the zircon disc to be optimized; The region combination decision module 300 obtains the number of regions of the zircon disk to be optimized that meet the optimal clamping area, selectively combines the machinable region and the clamping region according to the number of regions, and generates a final clamping point and a final processing region; The zircon disk comprehensive matching module 400 establishes a data matching platform to match the corresponding remaining zircon disks and the optimal clamping area according to the occupied area of ​​the tooth model.
