Description

Technical Field

[0001] This invention relates to the field of dental crown printing technology, and in particular to a device and method for mass printing dental crowns for implant abutments. Background Technology

[0002] Dentures are artificial dental devices used to replace missing teeth, typically designed and fabricated by professional dentists. Dentures have brought many benefits to humanity; they not only restore normal chewing but also improve pronunciation, protect remaining teeth, maintain oral health, and enhance facial aesthetics. Dentures are crucial for people with missing or unsightly teeth. However, the fabrication process is complex, requiring the taking of an impression in the patient's mouth, the creation of a model, adjustments to the denture's appearance based on the patient's preferences, and finally, printing and installation. While the initial steps can be discussed face-to-face between the dentist and patient, the printing process is independent. Current printing equipment requires manual adjustment of various parameters, resulting in low efficiency and long waiting times for denture installation. Therefore, improving the efficiency of denture printing is a pressing issue.

[0058] Figure 2 This is a schematic diagram illustrating the workflow of a method for batch printing dental crowns for implant abutments according to an embodiment of the present invention. Detailed Implementation

[0059] 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.

[0060] Example 1:

[0061] This embodiment provides a device for mass printing of dental crowns for implant abutments, such as... Figure 1 As shown, it includes:

[0062] The data optimization module is used to perform in-depth optimization of the patient's gingival sampling data using a gingival morphology database, determine the patient's abutment arrangement characteristics, and determine the patient's abutment printing data.

[0063] The denture simulation module is used to create several crown shapes for the patient based on the patient's requested requirements and the abutment arrangement features, and to construct crown printing data corresponding to each crown shape.

[0064] The print selection module is used to simulate the printing effect corresponding to each of the dental crown printing data according to the patient's facial data, and select the target dental crown printing data according to the instruction.

[0065] The printing execution module is used to print the patient's abutment and crown according to the abutment printing data and the target crown printing data, respectively.

[0066] In this example, the denture has two forms: one consists of an abutment and a crown, and the other consists of a crown alone.

[0067] In this example, the gingival morphology database represents a database that stores several gingival morphology data.

[0068] In this example, the abutment print data represents the data presented when the abutment for this patient was printed;

[0069] In this example, the abutment arrangement features represent the characteristics of the patient's abutments;

[0070] In this example, the crown printing data represents the data presented when printing the patient's crowns, and one crown shape corresponds to one crown printing data.

[0071] In this example, facial data refers to data about the patient's facial organs and contours obtained after taking a photograph of the patient's face;

[0072] In this example, several identical dental crowns are printed in batches, and then relevant personnel make minor adjustments to the crowns according to the patient's needs.

[0073] The working principle and beneficial effects of the above technical solution are as follows: In order to improve the efficiency of denture printing and ensure that patients can wear suitable and aesthetically pleasing dentures, the gingival sampling data of the patients is first deeply optimized based on the gingival database to determine the abutment arrangement characteristics and abutment printing data of the patients. Then, the crown morphology of the patients is created according to their needs. The printing effect of each crown morphology is obtained through simulation. Then, according to the instructions of the patients or doctors, the target crown printing data suitable for the patients is selected, thereby controlling the printing equipment to print the abutments and crowns separately. In this way, not only can the printing work be completed, but the printed products can also be ensured to meet the needs of the patients. In addition, this method can determine the preparation of the printing equipment and laser parameters in the early stage of printing, so as to quickly respond to the printing needs when printing is required, and achieve the goal of high efficiency and high quality.

[0074] Example 2:

[0075] Based on Example 1, the data optimization module of the dental crown batch printing device for implant abutments includes:

[0076] The optimization preparation unit is used to divide the patient's gingival sampling data into several single-tooth sub-data, search the library-related data corresponding to each single-tooth sub-data in the gingival morphology database, and construct several single-tooth features corresponding to each single-tooth sub-data using the data overlap information between the library-related data and the single-tooth data.

[0077] The optimized execution unit is used to divide the region of several single tooth features corresponding to each single tooth sub-data according to the gingival sampling data, determine the gingival margin region of the patient, classify the gingival sampling data located in the upper part of the gingival margin region as explicit data, and classify the gingival sampling data located in the lower part of the gingival margin region as embedded data;

[0078] The abutment simulation unit is used to construct the preliminary abutment shape of the patient based on the single tooth feature, to perform appearance correction on the preliminary abutment shape using the explicit data, and to perform embedded reinforcement on the preliminary abutment shape using the embedded data, so as to obtain the effective abutment shape of the patient.

[0079] The data conversion unit is used to determine the abutment layout characteristics of the patient based on the outline of the effective abutment shape, perform data description on the effective abutment shape, and reorganize several descriptive data of the effective abutment shape to generate the patient's abutment printing data.

[0080] In this example, single-tooth data refers to data describing a single tooth in the gingival sampling data;

[0081] In this example, the library-related data represents the existing data in the gingival morphology database related to single-tooth data;

[0082] In this example, the gingival margin area refers to the junction between the gingiva and the tooth surface;

[0083] In this example, the explicit data represents the data visible on the patient's teeth, while the embedded data represents the data embedded inside the patient's gums.

[0084] The working principle and beneficial effects of the above technical solution are as follows: In order to better serve patients and provide them with aesthetically pleasing and healthy dentures, the patient's gingival sampling data is first divided into single-tooth sub-data. Then, relevant data is searched in the gingival morphology database to construct the patient's single-tooth features. Further, the location of the gingival margin area is determined first, and then the gingival sampling data is divided into regions. By using the single-tooth features, the patient's preliminary abutment shape is constructed. The explicit and implicit data obtained from the region division are used to correct the preliminary abutment shape to construct the patient's effective abutment shape. Based on the data presented by the effective abutment shape and its arrangement characteristics, this method not only allows for analysis of each single tooth, but also allows for adjustment of the abutment shape according to the actual situation, forming an abutment that meets the patient's chewing needs. At the same time, printing data is generated, and the printing equipment can prepare the printing work in advance according to the needs to improve the subsequent printing efficiency.

[0085] Example 3:

[0086] Based on Example 1, the dental crown mass printing device for implant abutments, the denture simulation module, includes:

[0087] The demand parsing unit is used to decompose and train the patient's submitted demands to determine the first correlation between the submitted demands and the base station layout features and the second correlation between the submitted demands and the base station printing data, and to add corresponding matching tags to the submitted demands.

[0088] The crown construction unit is used to construct the initial crown morphology of the patient based on the submitted requirements, determine several crown correction positions included in the initial crown morphology according to the matching tags, determine the correction range of the initial crown morphology according to the first correlation relationship, and determine the numerical range of the initial crown morphology according to the second correlation relationship.

[0089] The crown correction unit is used to correct the corresponding correction range based on the numerical range, obtain several crown morphologies for the patient based on each correction result, and mark the differences between the crowns of different crown morphologies.

[0090] The data determination unit is used to obtain the target crown shape with the fewest differences between the crowns, describe the target crown shape, obtain the crown printing data corresponding to the target crown shape, and adjust the crown printing data based on the differences between different crown shapes to obtain the crown printing data corresponding to each crown shape.

[0091] In this example, the first association represents the relationship between the submitted requirements and the base station layout features, and the second association represents the relationship between the submitted requirements and the base station printing data;

[0092] In this example, the matching label represents the identifier that matches the submitted requirements with the base station layout features, and the identifier that matches the submitted requirements with the base station printing data.

[0093] In this example, the correction range represents the area in the initial crown morphology that needs to be corrected, and the numerical range represents the numerical range of the intensity of the correction to the initial crown morphology.

[0094] The working principle and beneficial effects of the above technical solution are as follows: Since each patient's needs are different, and some patients have a low level of understanding of dentistry, multiple different crown morphologies are provided to patients before printing. First, a preliminary crown morphology is constructed based on the patient's stated requirements. Then, the preliminary crown morphology is modified and adjusted based on the first correlation between the stated requirements and the abutment arrangement features, and the second correlation between the stated requirements and the abutment printing data. The patient's crown morphology is generated based on the modification results. To facilitate subsequent work, differences between the different crown morphologies are pre-screened. Then, data description is performed on the target crown morphology with the fewest differences. The data obtained is then adjusted using the differences between different crown morphologies to generate the crown printing data for each crown morphology. This method not only provides patients with a variety of crown morphologies but also ensures the accuracy of printing data, improves the printing efficiency of the printing equipment, and provides a good printing reference.

[0095] Example 4:

[0096] Based on Example 3, the device for mass printing dental crowns for implant abutments further includes:

[0097] Each of the printed data for the crown is cleaned to obtain several key features of the crown corresponding to the crown morphology.

[0098] The key features of the crown are clustered, and the crown morphology is sorted according to the number of cluster features from high to low. A recommended morphology order is generated and displayed.

[0099] The working principle and beneficial effects of the above technical solution are as follows: Since a dental crown is a small object, its precision determines its practicality. Therefore, recommendations are made to patients based on the key characteristics of the dental crown to help them choose a suitable dental crown appearance.

[0100] Example 5:

[0101] Based on Example 1, the batch printing device for dental crowns of implant abutments, wherein the printing selection module includes:

[0102] The facial analysis unit is used to acquire and construct the patient's facial contour based on the patient's facial data, use AI technology to analyze several facial aesthetic points contained in the facial contour, and search for the aesthetic influencing factors corresponding to each facial aesthetic point in the big data.

[0103] The effect simulation unit is used to input the printing data of each crown into the facial contour to obtain the facial simulation effect corresponding to each crown shape, and to evaluate the aesthetics of each facial simulation effect according to the aesthetic influencing factors to obtain the aesthetics report corresponding to each facial simulation effect.

[0104] The preliminary selection unit is used to determine the aesthetically affected features corresponding to each facial simulation effect based on the aesthetic report, filter the target facial simulation effects that meet the aesthetic requirements based on the feature values ​​of each aesthetically affected feature, and determine several printing effects for the patient.

[0105] The crown determination unit is used to show the patient each of the printing effects, determine the target crown printing data according to the patient's instructions, and deduce and display the patient's crown maintenance plan based on the target crown printing data and the corresponding target crown morphology.

[0106] The working principle and beneficial effects of the above technical solution are as follows: Utilizing AI technology to analyze the aesthetic viewpoints and influencing factors of a patient's facial contours not only allows for keeping up with current trends but also provides patients with inspiration for crown selection. First, AI technology analyzes the patient's facial contours to determine their aesthetic viewpoints and influencing factors. Then, the crown printing data is input for simulation and aesthetic evaluation. Based on the generated aesthetic report, the impact of each facial simulation effect is determined, and facial simulation effects that meet aesthetic requirements are selected to construct the corresponding printing effect. Finally, the target crown printing data is determined based on the patient's needs, while also providing the patient with crown maintenance plans, facilitating advance learning and extending the lifespan of the dentures.

[0107] Example 6:

[0108] Based on Example 1, the batch printing device for dental crowns of implant abutments, wherein the printing execution module includes:

[0109] The printing preparation unit is used to determine several printing execution conditions for this printing based on the abutment printing data and the target crown printing data, and to set corresponding cause identification codes and effect identification codes for the printed abutment finished product and the printed crown finished product, respectively.

[0110] The printing execution unit is used to control the printing equipment to perform printing work using the printing execution conditions, thereby obtaining the abutment and crown of the patient. The printed product is matched according to the cause identification code and the effect identification code to construct and display the appearance effect of the patient's abutment-denture.

[0111] In this example, the printing execution conditions include: pre-printing preparations, laser parameters during printing, and the method of transporting the printed product.

[0112] In this example, the cause identification code and the effect identification code are respectively set on the abutment and crown corresponding to the same single tooth position of the same patient. They are used to distinguish patients and to distinguish the marks according to position.

[0113] The working principle and beneficial effects of the above technical solution are as follows: The execution conditions for this printing are constructed based on the abutment printing data and the target crown printing data. In order to avoid misassembly, the abutment and crown are matched and coded before printing. After printing, the matching is performed in time to obtain the appearance effect for the patient and the doctor to refer to. This improves the intelligence of the device, provides patients with a good medical environment and medical guidance, and gives patients an open and transparent medical process.

[0114] Example 7:

[0115] Based on Example 5, the batch printing device for dental crowns of implant abutments, wherein the printing execution module further includes:

[0116] A special processing unit is used to adjust non-target facial simulation effects that do not meet aesthetic requirements according to special processing instructions uploaded by the doctor, so as to obtain a suitable facial simulation effect for the patient and determine several printing effects for the patient.

[0117] The working principle and beneficial effects of the above technical solution are as follows: Since some patients have complex gingival conditions and require special treatment, the best implantation effect, but with lower aesthetics, will be selected for printing to prioritize the patient's good chewing needs.

[0118] Example 8:

[0119] Based on Example 1, the device for mass printing dental crowns for implant abutments further includes:

[0120] The independent printing module is used to control the printing device to print the abutment or crown separately based on the independent printing instructions uploaded by the doctor.

[0126] Step 3: Simulate the printing effect corresponding to each of the above-mentioned crown printing data according to the patient's facial data, and select the target crown printing data according to the instructions;

[0127] Step 4: Print the abutment and crown for the patient according to the abutment printing data and the target crown printing data, respectively.

[0128] In this example, the denture has two forms: one consists of an abutment and a crown, and the other consists of a crown alone.

[0129] In this example, the gingival morphology database represents a database that stores several gingival morphology data.

[0130] In this example, the abutment print data represents the data presented when the abutment for this patient was printed;

[0131] In this example, the abutment arrangement features represent the characteristics of the patient's abutments;

[0132] In this example, the crown printing data represents the data presented when printing the patient's crowns, and one crown shape corresponds to one crown printing data.

[0133] In this example, facial data refers to data about the patient's facial organs and contours obtained after taking a photograph of the patient's face.

[0134] The working principle and beneficial effects of the above technical solution are as follows: In order to improve the efficiency of denture printing and ensure that patients can wear suitable and aesthetically pleasing dentures, the gingival sampling data of the patients is first deeply optimized based on the gingival database to determine the abutment arrangement characteristics and abutment printing data of the patients. Then, the crown morphology of the patients is created according to their needs. The printing effect of each crown morphology is obtained through simulation. Then, according to the instructions of the patients or doctors, the target crown printing data suitable for the patients is selected, thereby controlling the printing equipment to print the abutments and crowns separately. In this way, not only can the printing work be completed, but the printed products can also be ensured to meet the needs of the patients. In addition, this method can determine the preparation of the printing equipment and laser parameters in the early stage of printing, so as to quickly respond to the printing needs when printing is required, and achieve the goal of high efficiency and high quality.

[0135] Example 10:

[0136] Based on Example 9, the method for batch printing of dental crowns for implant abutments, step 1 includes:

[0137] Step 11: Divide the patient's gingival sampling data into several single-tooth sub-data. Search the library-related data corresponding to each single-tooth sub-data in the gingival morphology database. Construct several single-tooth features corresponding to each single-tooth sub-data using the data overlap information between the library-related data and the single-tooth data.

[0138] Step 1 2: Based on the gingival sampling data, divide the region of several single tooth features corresponding to each single tooth sub-data to determine the gingival margin region of the patient. The gingival sampling data located in the upper part of the gingival margin region is regarded as explicit data, and the gingival sampling data located in the lower part of the gingival margin region is regarded as embedded data.

[0139] Step 1 3: Construct the preliminary abutment shape of the patient based on the single tooth feature, use the explicit data to modify the appearance of the preliminary abutment shape, and use the embedded data to reinforce the preliminary abutment shape to obtain the effective abutment shape of the patient.

[0140] Step 14: Determine the abutment layout features of the patient based on the outline of the effective abutment shape, perform data description on the effective abutment shape, reorganize several descriptive data of the effective abutment shape, and generate the abutment printing data of the patient.

[0141] In this example, single-tooth data refers to data describing a single tooth in the gingival sampling data;

[0142] In this example, the library-related data represents the existing data in the gingival morphology database related to single-tooth data;

[0143] In this example, the gingival margin area refers to the junction between the gingiva and the tooth surface;

[0144] In this example, the explicit data represents the data visible on the patient's teeth, while the embedded data represents the data embedded inside the patient's gums.

[0145] The working principle and beneficial effects of the above technical solution are as follows: In order to better serve patients and provide them with aesthetically pleasing and healthy dentures, the patient's gingival sampling data is first divided into single-tooth sub-data. Then, relevant data is searched in the gingival morphology database to construct the patient's single-tooth features. Further, the location of the gingival margin area is determined first, and then the gingival sampling data is divided into regions. By using the single-tooth features, the patient's preliminary abutment shape is constructed. The explicit and implicit data obtained from the region division are used to correct the preliminary abutment shape to construct the patient's effective abutment shape. Based on the data presented by the effective abutment shape and its arrangement characteristics, this method not only allows for analysis of each single tooth, but also allows for adjustment of the abutment shape according to the actual situation, forming an abutment that meets the patient's chewing needs. At the same time, printing data is generated, and the printing equipment can prepare the printing work in advance according to the needs to improve the subsequent printing efficiency.
