Description

Technical Field

[0001] This invention relates to the field of dental implant manufacturing technology, and in particular to an integrated printing method and system for implanting a superstructure metal inner crown. Background Technology

[0002] In dental implant treatment, the implant superstructure is a crucial component connecting the implant abutment and the crown. Its precision and stability directly affect the outcome and lifespan of the implant restoration. Traditionally, implant superstructures are manufactured using a split-processing method, where the threaded base is first fabricated using casting or forging, the superstructure is then machined separately, and finally, the two are assembled by welding or bonding.

[0003] However, this modular processing method has many drawbacks: on the one hand, assembly errors are prone to occur after modular processing, resulting in insufficient coaxiality between the inner crown and the base, affecting the overall stability of the implant, and problems such as loosening and falling off may occur after long-term use; on the other hand, stress concentration may be introduced during welding or bonding, reducing the mechanical strength of the metal inner crown, and the assembly process is cumbersome and has low production efficiency, making it difficult to meet the needs of large-scale personalized production.

[0004] In addition, traditional processing methods lack effective positioning marking and traceability mechanisms. During mass production, it is not only difficult to accurately control the printing position of the inner crown, resulting in poor product consistency, but also impossible to quickly link the inner crown with the corresponding patient information. Once a quality problem occurs, it is difficult to trace the source, which poses a safety hazard to clinical applications.

[0005] Therefore, there is an urgent need for a manufacturing method for implantable upper metal inner crowns that can achieve integrated manufacturing, improve precision and production efficiency, and have traceability functions. Summary of the Invention

[0006] This invention provides an integrated printing method and system for implanting a superstructure metal inner crown. The integrated printing achieves a seamless connection between the threaded base and the inner crown, while laser marking enables precise positioning and patient information traceability, thereby improving product quality and production efficiency.

[0007] This invention provides an integrated printing method for implanting a superior metal inner crown, comprising:

[0008] Step 1: Control the metal printing equipment to perform the base printing task according to the production task to obtain several threaded bases, and use a multi-functional laser device to mark the inner crown printing position corresponding to each threaded base;

[0009] Step 2: Transport each of the threaded bases to the quality supervision area for product qualification verification to obtain the qualification status of each of the threaded bases;

[0010] Step 3: Control the metal printing equipment to print the inner crown at the inner crown printing position on the qualified threaded base with normal conditions, so as to obtain an integrated inner crown;

[0011] Step 4: Determine the matching patient for each integrated inner crown according to the production task, and set a corresponding coding mark for each integrated inner crown using the multifunctional laser device.

[0012] In one feasible approach

[0013] Also includes:

[0014] The production quantity for this operation will be determined based on the aforementioned production task.

[0015] When the actual production quantity corresponding to the integrated inner crown does not match the current production quantity, the unfinished sub-task is determined according to the coding mark.

[0016] The metal printing device is controlled to perform supplementary printing based on the unfinished sub-task;

[0017] When three consecutive supplementary printings are performed, the three-dimensional structure to be printed is constructed based on each of the unfinished sub-tasks described above.

[0018] The parameters of the metal printing equipment are adjusted according to the required three-dimensional structure, and supplementary printing is performed using the adjusted metal printing equipment.

[0019] In one feasible approach

[0020] Step 1 includes:

[0021] Step 11: Identify several printing sub-tasks included in the production task, and draw the three-dimensional inner crown structure corresponding to each printing sub-task respectively. Printing sub-tasks with the same three-dimensional inner crown structure are regarded as the same printing class, and the printing differences between different printing classes are obtained.

[0022] Step 12: Based on the different printing points, deduce the parameter adjustment amount corresponding to the metal printing device switching from one printing type to another, construct several complete printing switching processes, and control the metal printing device to execute the optimal complete printing switching process with the minimum total parameter adjustment amount;

[0023] Step 13: Obtain the real-time printing progress of the metal printing equipment, determine the base attributes corresponding to each threaded base in combination with the optimal complete printing switching process, and determine the printing sub-task and corresponding three-dimensional inner crown structure corresponding to each threaded base in combination with the production task.

[0024] Step 14: After completing all the printing sub-tasks, the production task is determined to be completed. The inner crown structure is identified in each of the three-dimensional inner crown structures. Based on the identification results, the inner crown printing position corresponding to each threaded base is determined. At the same time, the multi-functional laser device is controlled to set corresponding marks on the inner crown printing position.

[0025] In one feasible approach

[0026] Step 14 includes:

[0027] Step 141: When the metal printing device completes a threaded base, a corresponding printing sub-task is matched for the threaded base, the real-time printing progress of the metal printing device is constructed, the time of completion of the production task is determined, and the real-time printing data of the metal printing device is collected at the same time.

[0028] Step 142: After completing the production task, construct a three-dimensional base structure corresponding to each thread base according to the real-time printing data, fuse the three-dimensional base structure with the corresponding three-dimensional crown structure, and divide each three-dimensional crown structure into a base structure and a crown structure according to the fusion result.

[0029] Step 143: Determine the base-crown connection position of the corresponding threaded base according to the positional relationship between the base structure and the crown structure in each three-dimensional crown structure, and enhance the base-crown connection position in the corresponding three-dimensional base structure to obtain the corresponding inner crown printing position on each threaded base;

[0030] Step 144: Control the multi-functional laser device to identify the corresponding inner crown printing position in the threaded base and mark it accordingly.

[0031] In one feasible approach

[0032] Step 2 includes:

[0033] Step 21: Transport each of the threaded bases to the quality supervision area for appearance and specification collection, obtain the quality inspection information of each of the threaded bases under each specified quality inspection dimension, and verify the conformity of each quality inspection information according to the BOM list of the production task.

[0034] Step 22: Obtain several verification results corresponding to each thread base, set corresponding verification attributes for each verification result in combination with the quality inspection dimension corresponding to each verification result, and identify defects in each verification result according to the defect identification method corresponding to each verification attribute.

[0035] Step 23: Construct an appearance image of the threaded base based on the quality inspection information generated from the appearance acquisition and the corresponding defect identification results, and obtain the pixel features corresponding to the defect identification results in the appearance image to generate and display the pass / fail status of each threaded base.

[0036] In one feasible approach

[0037] Also includes:

[0038] The location and extent of defects in each threaded base are determined based on the pixel features corresponding to each threaded base.

[0039] Locate the several base functions contained in the production base corresponding to the production task, map the base functions in the production base, and determine the functional location and functional scope corresponding to each base function;

[0040] Analyze the defect function corresponding to each pixel feature in each of the threaded bases;

[0041] Based on the aforementioned defective function, the threaded base is classified into defect-free products, products that can be modified, and products that cannot be modified, and then further categorized.

[0042] Extract the permitted modifications and the corresponding target defects;

[0043] Based on the target defect function, a product modification plan is generated, and the printing task of the metal printing equipment is adjusted according to the product modification plan to modify the permitted product.

[0044] In one feasible approach

[0045] Step 3 includes:

[0046] Step 31: Select qualified threaded bases that meet the production requirements based on the qualified conditions, and transport the qualified threaded bases to the printing area of ​​the metal printing equipment. Use a preset high-precision camera to take pictures of each qualified threaded base to obtain the base image corresponding to each qualified threaded base.

[0047] Step 32: Use the multi-functional laser device to scan the area to be printed to obtain the physical distance between each qualified thread base in the area to be printed and the metal printing device, and construct the virtual three-dimensional printing space of the metal printing device;

[0048] Step 33: Identify the inner crown printing position corresponding to the qualified threaded base in the base image, and mark each inner crown printing position in the virtual three-dimensional printing space. Determine the printing order corresponding to each qualified threaded base with the goal of minimizing the moving distance.

[0049] Step 34: Generate the printing parameter sequence of the metal printing device based on the inner crown position marking result, determine the execution order of each printing parameter in the printing parameter sequence using the printing order, and control the metal printing device to print the inner crown at the inner crown printing position to generate an integrated inner crown.

[0050] In one feasible approach

[0051] Also includes:

[0052] The real-time inner crown printing data of the metal printing device is acquired and transmitted to the virtual three-dimensional printing space for synchronous printing simulation, so as to obtain the virtual printing result corresponding to each integrated inner crown.

[0053] The virtual printing results are structurally analyzed. When a defective integrated inner crown with structural abnormalities is identified in the virtual three-dimensional printing space, the metal printing equipment is controlled to suspend the printing of the inner crown.

[0054] The printing parameter sequence is optimized based on the defect offset of the integrated defective inner crown, and the optimized printing parameter sequence is used to control the metal printing equipment to continue the printing of the inner crown.

[0055] In one feasible approach

[0056] Step 4 includes:

[0057] Step 41: Based on the production task, find the list of patients to be printed and the corresponding inner crown shape characteristics for each patient;

[0058] Step 42: Match the external features of each inner crown with different integrated inner crowns in terms of specifications and appearance to determine the matching patient corresponding to each integrated inner crown;

[0059] Step 43: Determine the patient code corresponding to each integrated inner crown based on the patient list, and control the multifunctional laser device to perform the corresponding coding marking.

[0060] This invention provides an integrated printing system for implanting a superior metal inner crown, comprising:

[0061] The base printing module is used to control the metal printing equipment to perform base printing tasks according to the production task to obtain several threaded bases, and to use a multi-functional laser device to mark the inner crown printing position corresponding to each of the threaded bases.

[0062] The conformity verification module is used to transport each of the threaded bases to the quality supervision area for product conformity verification, and to obtain the conformity status of each of the threaded bases.

[0063] The inner crown printing module is used to control the metal printing equipment to print the inner crown at the inner crown printing position on the qualified threaded base under normal conditions, so as to obtain an integrated inner crown.

[0064] The coding and marking module is used to determine the matching patient corresponding to each integrated inner crown according to the production task, and to set a corresponding coding mark for each integrated inner crown using the multifunctional laser device.

[0065] The beneficial effects of the above technical solution are as follows: To improve the lifespan of dentures, reduce adjustment procedures during clinical installation, and lower the risks of implant loosening and occlusal discomfort caused by structural deviations, the following steps are taken: First, a multi-functional laser device is used to mark the printing position of the inner crown, providing a millimeter-level precise positioning reference for subsequent inner crown printing and effectively controlling the positional deviation of the inner crown printing. Then, the threaded base undergoes product verification, and its core performance is comprehensively tested, avoiding ineffective processing of the inner crown on a substandard base and reducing waste of metal materials and printing time. Furthermore, to ensure that the threaded base and the inner crown use the same metal material, the metal printing process is controlled. The inner crown is printed on a qualified threaded base, avoiding the weak interface strength caused by material differences, welding, and bonding processes in traditional split processing. Finally, specific patient information is associated with the production task and a unique code is set. This not only meets the differences in oral anatomy among different patients, but also allows for quick matching of patients with corresponding inner crowns through coding, reducing the time cost of clinical sorting and verification, and improving the efficiency and accuracy of implant surgery. Furthermore, it is associated with information such as patient name, medical record number, and production batch, forming a full-process traceability chain. If quality problems occur in subsequent clinical practice, the specific production link and corresponding workpiece can be quickly located, facilitating problem investigation and responsibility determination, and improving the safety and reliability of clinical applications.

[0066] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0067] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0071] Figure 3 This is a schematic diagram of the composition of an integrated printing system for implanting a superstructure metal inner crown, according to an embodiment of the present invention.

[0072] Among them, frame 1 is the inner crown metal part, and frame 2 is the threaded base metal part. Detailed Implementation

[0073] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0074] Example 1:

[0075] This embodiment provides an integrated printing method for implanting a superior metal inner crown, such as... Figure 1 As shown, it includes:

[0076] Step 1: Control the metal printing equipment to perform the base printing task according to the production task to obtain several threaded bases, and use a multi-functional laser device to mark the inner crown printing position corresponding to each threaded base;

[0077] Step 2: Transport each of the threaded bases to the quality supervision area for product qualification verification to obtain the qualification status of each of the threaded bases;

[0078] Step 3: Control the metal printing equipment to print the inner crown at the inner crown printing position on the qualified threaded base with normal conditions, so as to obtain an integrated inner crown;

[0079] Step 4: Determine the matching patient for each integrated inner crown according to the production task, and set a corresponding coding mark for each integrated inner crown using the multifunctional laser device.

[0080] In this example, the present invention achieves seamless connection between the threaded base and the inner crown through integrated printing, fundamentally avoiding problems such as insufficient coaxiality and excessive gap caused by positioning deviation during the assembly process. This ensures the structural consistency between the inner crown and the base. The integrated molding structure allows stress to be evenly transferred between the base and the inner crown, significantly improving the flexural strength and fatigue resistance of the finished product, meeting the long-term oral chewing force requirements, and extending the service life of the implant.

[0081] In this example, the production task indicates the task of producing an integrated inner crown.

[0082] In this example, both the threaded base and the inner crown are made of metal, such as Figure 2 As shown, frame 1 is the inner crown metal part, and frame 2 is the threaded base metal part;

[0083] In this example, the multi-functional laser equipment achieves millimeter-level accuracy during marking. The same multi-functional laser equipment can be reused to complete two key processes: marking the inner crown printing position and marking the integrated inner crown coding. This eliminates the need for multiple dedicated marking devices, reducing equipment changeover time and space requirements, and simplifying the production layout.

[0084] In this example, the integrated inner crown refers to the product obtained by fixing the metal of the inner crown and the metal of the threaded base together with a screw.

[0085] In this example, the process of verifying the quality of the threaded base also includes: using X-ray flaw detection to eliminate defects such as internal pores and cracks, ensuring that all bases entering the inner crown printing stage are qualified, thus avoiding the risk of implant breakage and infection caused by base quality problems from the source;

[0086] In this example, one patient corresponds to one code.

[0087] The working principle and beneficial effects of the above technical solution are as follows: To improve the lifespan of dentures, reduce adjustment procedures during clinical installation, and lower the risks of implant loosening and occlusal discomfort caused by structural deviations, a multi-functional laser device is first used to mark the printing position of the inner crown. This provides a millimeter-level precise positioning reference for subsequent inner crown printing, effectively controlling the positional deviation of the inner crown printing. Then, the threaded base undergoes product verification, with comprehensive testing of its core performance. This avoids ineffective processing of the inner crown on a substandard base, reducing waste of metal materials and printing time. Furthermore, to ensure that the threaded base and the inner crown use the same metal material, the metal printing process is controlled... The inner crown is printed on a qualified threaded base, avoiding the weak interface strength caused by material differences, welding, and bonding processes in traditional split processing. Finally, specific patient information is associated with the production task and a unique code is set. This not only meets the differences in oral anatomy among different patients, but also allows for quick matching of patients with corresponding inner crowns through coding, reducing the time cost of clinical sorting and verification, and improving the efficiency and accuracy of implant surgery. Furthermore, it is associated with information such as patient name, medical record number, and production batch, forming a full-process traceability chain. If quality problems occur in subsequent clinical practice, the specific production link and corresponding workpiece can be quickly located, facilitating problem investigation and responsibility determination, and improving the safety and reliability of clinical applications.

[0088] Example 2:

[0089] Based on Example 1, the integrated printing method for implanting a superstructure metal inner crown further includes:

[0090] The production quantity for this operation will be determined based on the aforementioned production task.

[0091] When the actual production quantity corresponding to the integrated inner crown does not match the current production quantity, the unfinished sub-task is determined according to the coding mark.

[0092] The metal printing device is controlled to perform supplementary printing based on the unfinished sub-task;

[0093] When three consecutive supplementary printings are performed, the three-dimensional structure to be printed is constructed based on each of the unfinished sub-tasks described above.

[0094] The parameters of the metal printing equipment are adjusted according to the three-dimensional structure to be printed, and the adjusted metal printing equipment is used for supplementary printing.

[0095] The working principle and beneficial effects of the above technical solution are as follows: To ensure the smooth progress of printing and the pass rate of integrated inner crowns, the metal printing equipment is controlled to supplement printing based on the unfinished sub-tasks. Targeted supplementary printing is initiated for missing workpieces, eliminating the need to reprint completed and qualified workpieces, avoiding extra consumption of metal raw materials, and reducing the time cost of equipment idling or repeated debugging. When supplementary printing requests occur three times consecutively, it indicates that the metal printing equipment has malfunctioned. This malfunction can be resolved by adjusting parameters, effectively reducing batch scrap caused by continuous equipment malfunctions, improving long-term production stability, and avoiding large-scale production stoppages caused by equipment problems. Furthermore, the adjusted equipment parameters not only solve the current supplementary printing problem but also provide a better parameter benchmark for subsequent printing of similar workpieces, indirectly improving the overall dimensional accuracy and mechanical performance pass rate of the finished product, and reducing hidden quality problems caused by parameter mismatch.

[0096] Example 3:

[0097] Based on Example 1, the integrated printing method for implanting a superior metal inner crown, step 1 includes:

[0098] Step 11: Identify several printing sub-tasks included in the production task, and draw the three-dimensional inner crown structure corresponding to each printing sub-task respectively. Printing sub-tasks with the same three-dimensional inner crown structure are regarded as the same printing class, and the printing differences between different printing classes are obtained.

[0099] Step 12: Based on the different printing points, deduce the parameter adjustment amount corresponding to the metal printing device switching from one printing type to another, construct several complete printing switching processes, and control the metal printing device to execute the optimal complete printing switching process with the minimum total parameter adjustment amount;

[0100] Step 13: Obtain the real-time printing progress of the metal printing equipment, determine the base attributes corresponding to each threaded base in combination with the optimal complete printing switching process, and determine the printing sub-task and corresponding three-dimensional inner crown structure corresponding to each threaded base in combination with the production task.

[0101] Step 14: After completing all the printing sub-tasks, the production task is determined to be completed. The inner crown structure is identified in each of the three-dimensional inner crown structures. Based on the identification results, the inner crown printing position corresponding to each threaded base is determined. At the same time, the multi-functional laser device is controlled to set corresponding marks on the inner crown printing position.

[0102] In this example, a printing subtask represents the result of dividing a production task into several independent single tasks, that is, one printing subtask corresponds to one integrated inner crown;

[0103] In this example, the three-dimensional inner crown structure represents the inner crown structure drawn in three-dimensional space after performing a printing subtask;

[0104] In this example, if the core parameters of the metal printing equipment change frequently and significantly, it will not only increase the equipment calibration time but may also lead to parameter adaptation deviation. Therefore, the optimal complete printing switchover process with the least amount of total parameter adjustment is selected.

[0105] In this example, printing different dots represents the difference between different printing classes;

[0106] In this example, the base attribute represents the specifications and appearance of the threaded base;

[0107] In this example, one of the functions of the multi-functional laser device is to mark the printing position of the inner crown on the threaded base. Due to differences between different models of metal printing devices, manual or software calibration may be used when necessary. The processes are as follows:

[0108] The first method involves manual measurement followed by calibration.

[0109] The second method involves fixing the threaded base at a specified angle to the position to be calibrated, and then using printing and typesetting software to calibrate the fixed position.

[0110] The working principle and beneficial effects of the above technical solution are as follows: By integrating sub-tasks with the same specifications in the production task into the same printing category, the frequent start-up and shutdown and model switching of metal printing equipment are reduced. At the same time, the printing differences between different printing categories are accurately extracted to provide a clear basis for subsequent parameter adjustment, reducing the risk of misprinting or omission due to task mixing. Then, for multi-printing category switching scenarios, the optimal complete printing switching process with the least total parameter adjustment is selected by deriving the parameter adjustment amount. This reduces the losses and errors caused by frequent and large-scale adjustments of equipment parameters from the root. Furthermore, by locating the base attributes of the threaded base, the corresponding sub-task, and the three-dimensional inner crown structure through real-time printing progress and optimal switching process, the printing status and task information of the equipment can be synchronized in real time, greatly reducing the complexity of production management. Finally, by identifying the key features of the three-dimensional inner crown structure to determine the most suitable printing position and then controlling the multi-functional laser equipment for marking, the deviation of the inner crown printing position can be controlled within the micron range, providing a core guarantee for the structural accuracy of subsequent integrated printing and reducing clinical installation difficulties or occlusal discomfort caused by position deviation.

[0111] Example 4:

[0112] Based on Example 3, the integrated printing method for implanting a superior metal inner crown, step 14 includes:

[0113] Step 141: When the metal printing device completes a threaded base, a corresponding printing sub-task is matched for the threaded base, the real-time printing progress of the metal printing device is constructed, the time of completion of the production task is determined, and the real-time printing data of the metal printing device is collected at the same time.

[0114] Step 142: After completing the production task, construct a three-dimensional base structure corresponding to each thread base according to the real-time printing data, fuse the three-dimensional base structure with the corresponding three-dimensional crown structure, and divide each three-dimensional crown structure into a base structure and a crown structure according to the fusion result.

[0115] Step 143: Determine the base-crown connection position of the corresponding threaded base according to the positional relationship between the base structure and the crown structure in each three-dimensional crown structure, and enhance the base-crown connection position in the corresponding three-dimensional base structure to obtain the corresponding inner crown printing position on each threaded base;

[0116] Step 144: Control the multi-functional laser device to identify the corresponding inner crown printing position in the threaded base and mark it accordingly.

[0117] In this example, real-time print data refers to the data generated by the metal printing equipment during the printing process;

[0118] In this example, the base structure represents the threaded base portion of the three-dimensional crown structure, and the crown structure represents the crown portion of the three-dimensional crown structure.

[0119] In this example, the base-crown connection position indicates the location where the threaded base and the inner crown are threaded together;

[0120] In this example, enhancement processing refers to the process of rendering lines and highlighting key points at the abutment-crown connection.

[0121] The working principle and beneficial effects of the above technical solution are as follows: First, real-time tracking of printing progress and collection of printing data allow for timely monitoring of the printing status of the threaded base, providing accurate data support for subsequent steps such as 3D structural fusion and position determination. This ensures data continuity throughout the entire process from base printing to inner crown position marking, reducing errors caused by data gaps. Then, 3D structural fusion is used to divide the base and crown structures, clearly defining their boundaries and relationships, laying the foundation for determining the connection position. Furthermore, the base-crown connection position is determined based on the positional relationship, and this position is reinforced to specifically improve the structural strength of the connection, reducing loosening or damage caused by weak connections during subsequent use and extending the implant's lifespan. Finally, a multi-functional laser device is controlled to identify and mark the inner crown printing position. Utilizing the high precision of laser marking ensures that the marked position is highly consistent with the design requirements, providing a clear and accurate reference for subsequent inner crown printing and reducing printing deviations. This makes the metal printing equipment's operation more organized, reducing the risk of task confusion or omission, ensuring efficient and planned production, and adapting to different implant needs, thus enhancing the flexibility and applicability of the production method.

[0122] Example 5:

[0123] Based on Example 1, the integrated printing method for implanting a superior metal inner crown, step 2 includes:

[0124] Step 21: Transport each of the threaded bases to the quality supervision area for appearance and specification collection, obtain the quality inspection information of each of the threaded bases under each specified quality inspection dimension, and verify the conformity of each quality inspection information according to the BOM list of the production task.

[0125] Step 22: Obtain several verification results corresponding to each thread base, set corresponding verification attributes for each verification result in combination with the quality inspection dimension corresponding to each verification result, and identify defects in each verification result according to the defect identification method corresponding to each verification attribute.

[0126] Step 23: Construct an appearance image of the threaded base based on the quality inspection information generated from the appearance acquisition and the corresponding defect identification results, and obtain the pixel features corresponding to the defect identification results in the appearance image to generate and display the pass / fail status of each threaded base.

[0127] In this example, the BOM (Bill of Materials) list represents a list of all materials, parts, raw materials, components, and related information for a product or project;

[0128] In this example, the quality inspection dimensions include: the six-view image dimension of the threaded base, the specification location, and the quality dimension;

[0129] In this example, pixel features represent the characteristics of the defect identification results as presented in the appearance image.

[0130] The working principle and beneficial effects of the above technical solution: As the core support structure for implanting the upper metal inner crown, the quality of the threaded base directly affects the assembly accuracy of the inner crown and the base, as well as the final implantation effect. To ensure the quality of the threaded base, firstly, appearance and specifications of the threaded base are collected, and quality inspection information is generated based on each specified quality inspection dimension. This information is then verified against the BOM (Bill of Materials) list of the production task. This approach not only inspects a single dimension but also covers important dimensions such as appearance and specifications, avoiding hidden quality problems caused by missing dimensions. Finally, corresponding quality inspection dimensions are matched to different verification results. The technology verifies the attributes of defects and adapts them to specific defect identification methods, avoiding the limitations of general identification methods. This significantly improves the accuracy of defect identification, reduces the probability of false positives and false negatives, and further transforms quality inspection information and defect identification results into appearance images, marking the pixel features corresponding to the defects. Quality inspectors and production managers can more intuitively perceive the specific details of the defects. In addition, the technology can also generate and display the qualification status of each thread base in a timely manner, enabling the production end to quickly screen qualified products for the next stage, avoiding production delays caused by the mixing of qualified and unqualified products, and improving the overall production flow efficiency.

[0131] Example 6:

[0132] Based on Example 5, the integrated printing method for implanting a superstructure metal inner crown further includes:

[0133] The location and extent of defects in each threaded base are determined based on the pixel features corresponding to each threaded base.

[0134] Locate the several base functions contained in the production base corresponding to the production task, map the base functions in the production base, and determine the functional location and functional scope corresponding to each base function;

[0135] Analyze the defect function corresponding to each pixel feature in each of the threaded bases;

[0136] Based on the aforementioned defective function, the threaded base is classified into defect-free products, products that can be modified, and products that cannot be modified, and then further categorized.

[0137] Extract the permitted modifications and the corresponding target defects;

[0138] Based on the target defect function, a product modification plan is generated, and the printing task of the metal printing equipment is adjusted according to the product modification plan to modify the permitted product.

[0139] In this example, the production base refers to the flawless threaded base obtained after the production task is completed;

[0140] In this example, the base function represents the functionality required for a flawless threaded base.

[0141] The working principle and beneficial effects of the above technical solution are as follows: First, based on the pixel features obtained during the quality inspection of the threaded base, the location and range of defects in the base are determined. Then, combined with the various base functions included in the production task, these functions are mapped onto the base to clarify the location and range of each function. Subsequently, the impact of each defect on the base function is analyzed. Then, based on the defect function, the threaded base is divided into three categories: defect-free products, products that can be modified, and products that cannot be modified, and processed accordingly. For products that can be modified, the corresponding target defect function is extracted, and a special product modification plan is generated. Then, the printing task of the metal printing equipment is adjusted according to the modification plan. Finally, the products that can be modified are modified in a targeted manner, realizing refined control of base defects and efficient utilization of repairable defects.

[0142] Example 7:

[0143] Based on Example 1, the integrated printing method for implanting a superior metal inner crown, step 3 includes:

[0144] Step 31: Select qualified threaded bases that meet the production requirements based on the qualified conditions, and transport the qualified threaded bases to the printing area of ​​the metal printing equipment. Use a preset high-precision camera to take pictures of each qualified threaded base to obtain the base image corresponding to each qualified threaded base.

[0145] Step 32: Use the multi-functional laser device to scan the area to be printed to obtain the physical distance between each qualified thread base in the area to be printed and the metal printing device, and construct the virtual three-dimensional printing space of the metal printing device;

[0146] Step 33: Identify the inner crown printing position corresponding to the qualified threaded base in the base image, and mark each inner crown printing position in the virtual three-dimensional printing space. Determine the printing order corresponding to each qualified threaded base with the goal of minimizing the moving distance.

[0147] Step 34: Generate the printing parameter sequence of the metal printing device based on the inner crown position marking result, determine the execution order of each printing parameter in the printing parameter sequence using the printing order, and control the metal printing device to print the inner crown at the inner crown printing position to generate an integrated inner crown.

[0148] In this example, each qualified threaded base corresponds to a base image;

[0149] In this example, the virtual 3D printing space represents the result of using a virtual method to present the printing space where production tasks are performed;

[0150] In this example, the printing parameter sequence represents a sequence of parameters that the metal printing device continuously adjusts during the printing process;

[0151] In this example, the metal printing equipment needs to accurately print the inner crown onto the inner crown printing position to ensure that the inner crown printing position matches the connection surface and stress height of the threaded base.

[0152] The working principle and beneficial effects of the above technical solution are as follows: To ensure a high degree of connection between the inner crown and the threaded base, qualified threaded bases that meet production requirements are first selected and transported to the printing area. Images of the qualified threaded bases are obtained by capturing images with a pre-set high-precision camera. Simultaneously, a multi-functional laser device is used to scan the physical distance between the base and the metal printing equipment and construct a virtual three-dimensional printing space. Then, the printing position of the inner crown is identified in the base image and marked in the virtual space. The printing sequence is determined with the goal of minimizing the movement distance. Finally, a printing parameter sequence is generated based on the inner crown position markings, and the parameter execution order is determined according to the printing order. The equipment is controlled to print the inner crown at the corresponding position, forming an integrated inner crown. In this way, through high-precision image recognition and virtual space modeling, the precise positioning of the inner crown printing position is achieved, ensuring the matching accuracy between the inner crown and the base. Planning the printing sequence with the minimum movement distance reduces unnecessary equipment movement, improves production efficiency, and reduces energy consumption. At the same time, it ensures the reliability of the integrated inner crown structure, improving the stability and success rate of clinical implantation.

[0153] Example 8:

[0154] Based on Example 7, the integrated printing method for implanting a superstructure metal inner crown further includes:

[0155] The real-time inner crown printing data of the metal printing device is acquired and transmitted to the virtual three-dimensional printing space for synchronous printing simulation, so as to obtain the virtual printing result corresponding to each integrated inner crown.

[0156] The virtual printing results are structurally analyzed. When a defective integrated inner crown with structural abnormalities is identified in the virtual three-dimensional printing space, the metal printing equipment is controlled to suspend the printing of the inner crown.

[0157] The printing parameter sequence is optimized based on the defect offset of the integrated defective inner crown, and the optimized printing parameter sequence is used to control the metal printing equipment to continue the printing of the inner crown.

[0158] In this example, the virtual printing result represents the result of synchronous printing in a virtual 3D printing space.

[0159] The working principle and beneficial effects of the above technical solution are as follows: First, real-time data of the metal printing equipment during the printing process of the inner crown is acquired and transmitted to the previously constructed virtual 3D printing space. Virtual simulation of the inner crown printing process is achieved through data synchronization, generating virtual printing results for each integrated inner crown. Then, structural analysis is performed on the virtual printing results. If a defective integrated inner crown with structural abnormalities is identified in the virtual space, the metal printing equipment is controlled to pause the current inner crown printing operation. Next, the degree of defect offset of the defective integrated inner crown is analyzed, and the original printing parameter sequence is optimized based on this offset. Finally, the optimized... The subsequent printing parameter sequence re-controls the metal printing equipment to resume the inner crown printing process, ensuring that the printed inner crowns meet quality requirements. This method allows for the early detection of structural anomalies during the physical printing process, avoiding the waste of raw materials and printing time caused by continuous defects, and reducing ineffective production costs. Timely pausing of the equipment and optimization of printing parameters based on defect offset can quickly correct printing deviations, reduce the output of defective products, and significantly improve the printing pass rate of integrated inner crowns. At the same time, the combination of virtual simulation and parameter optimization eliminates the need for frequent machine shutdowns for inspection or the need to redo the entire process plan, ensuring the continuity of the printing process and improving production efficiency.

[0160] Example 9:

[0161] Based on Example 1, the integrated printing method for implanting a superior metal inner crown, step 4 includes:

[0162] Step 41: Based on the production task, find the list of patients to be printed and the corresponding inner crown shape characteristics for each patient;

[0163] Step 42: Match the external features of each inner crown with different integrated inner crowns in terms of specifications and appearance to determine the matching patient corresponding to each integrated inner crown;

[0164] Step 43: Determine the patient code corresponding to each integrated inner crown based on the patient list, and control the multifunctional laser device to perform the corresponding coding marking.

[0165] In this example, one patient corresponds to one patient code;

[0166] In this example, the purpose of specification matching is to identify an integrated inner crown of the model that matches the patient's needs, and the purpose of appearance matching is to identify an integrated inner crown that matches the patient's code.

[0167] The working principle and beneficial effects of the above technical solution are as follows: First, the list of patients involved in this printing and the unique inner crown shape characteristics of each patient are identified through task information, clarifying the target objects and core technical parameters for printing. Then, based on the patient's inner crown shape characteristics, existing integrated inner crowns are matched in terms of specifications and appearance to select the integrated inner crown that best matches the inner crown characteristics of each patient, determining the correspondence between the two. Finally, a unique patient code is assigned to the successfully matched integrated inner crown according to the patient list. Then, by controlling a multi-functional laser device, the code is accurately marked on the corresponding integrated inner crown to achieve precise binding between the inner crown and the patient, preparing for subsequent implantation and use, effectively avoiding implantation adaptation problems caused by mismatch in inner crown specifications or appearance, and improving the success rate of implantation surgery.

[0168] Example 10:

[0169] This embodiment provides an integrated printing system for implanting a superior metal inner crown, such as... Figure 3 As shown, it includes:

[0170] The base printing module is used to control the metal printing equipment to perform base printing tasks according to the production task to obtain several threaded bases, and to use a multi-functional laser device to mark the inner crown printing position corresponding to each of the threaded bases.

[0171] The conformity verification module is used to transport each of the threaded bases to the quality supervision area for product conformity verification, and to obtain the conformity status of each of the threaded bases.

[0172] The inner crown printing module is used to control the metal printing equipment to print the inner crown at the inner crown printing position on the qualified threaded base under normal conditions, so as to obtain an integrated inner crown.

[0173] The coding and marking module is used to determine the matching patient corresponding to each integrated inner crown according to the production task, and to set a corresponding coding mark for each integrated inner crown using the multifunctional laser device.

[0174] In this example, the production task indicates the task of producing an integrated inner crown.

[0175] In this example, both the threaded base and the inner crown are made of metal, such as Figure 2As shown, frame 1 is the inner crown metal part, and frame 2 is the threaded base metal part;

[0176] In this example, the multi-functional laser equipment achieves millimeter-level accuracy during marking. The same multi-functional laser equipment can be reused to complete two key processes: marking the inner crown printing position and marking the integrated inner crown coding. This eliminates the need for multiple dedicated marking devices, reducing equipment changeover time and space requirements, and simplifying the production layout.

[0177] In this example, the integrated inner crown refers to the product obtained by fixing the metal of the inner crown and the metal of the threaded base together with a screw.

[0178] In this example, the process of verifying the quality of the threaded base also includes: using X-ray flaw detection to eliminate defects such as internal pores and cracks, ensuring that all bases entering the inner crown printing stage are qualified, thus avoiding the risk of implant breakage and infection caused by base quality problems from the source;

[0179] In this example, one patient corresponds to one code.

[0180] The working principle and beneficial effects of the above technical solution are as follows: To improve the lifespan of dentures, reduce adjustment procedures during clinical installation, and lower the risks of implant loosening and occlusal discomfort caused by structural deviations, a multi-functional laser device is first used to mark the printing position of the inner crown. This provides a millimeter-level precise positioning reference for subsequent inner crown printing, effectively controlling the positional deviation of the inner crown printing. Then, the threaded base undergoes product verification, with comprehensive testing of its core performance. This avoids ineffective processing of the inner crown on a substandard base, reducing waste of metal materials and printing time. Furthermore, to ensure that the threaded base and the inner crown use the same metal material, the metal printing process is controlled... The inner crown is printed on a qualified threaded base, avoiding the weak interface strength caused by material differences, welding, and bonding processes in traditional split processing. Finally, specific patient information is associated with the production task and a unique code is set. This not only meets the differences in oral anatomy among different patients, but also allows for quick matching of patients with corresponding inner crowns through coding, reducing the time cost of clinical sorting and verification, and improving the efficiency and accuracy of implant surgery. Furthermore, it is associated with information such as patient name, medical record number, and production batch, forming a full-process traceability chain. If quality problems occur in subsequent clinical practice, the specific production link and corresponding workpiece can be quickly located, facilitating problem investigation and responsibility determination, and improving the safety and reliability of clinical applications.
