Description

Technical Field

[0001] The present invention relates to the technical field of dental crown printing, and in particular to a device and method for batch printing dental crowns of implant bases. Background Art

[0002] Dentures are artificial dental devices used to replace missing teeth. They are usually simulated teeth designed and made by professional dentists. The emergence of dentures has brought a lot of meaning to mankind. Dentures can not only restore normal chewing for patients, but also improve patients' pronunciation, protect patients' remaining teeth, maintain oral health, and provide patients with a beautiful facial image. Dentures are very important for people who are missing teeth or have unsightly teeth, but the denture production process is also very complicated. It is necessary to first take a mold from the patient's mouth, then make a model, and then adjust the appearance of the denture according to the patient's requirements. Finally, it is printed and installed. The preliminary work can be communicated face-to-face between the doctor and the patient, but the printing work is carried out independently, and the current printing device requires manual adjustment of various parameters to achieve printing work, which leads to very low printing efficiency. Patients need to wait a long time before they can successfully install dentures. Therefore, how to improve the efficiency of denture printing has become a problem that needs to be solved urgently.

[0074] Example 2:

[0075] On the basis of Example 1, the apparatus for batch printing dental crowns for implant abutments, the data optimization module, comprises:

[0076] an optimization preparation unit, configured to divide the patient's gingival sampling data into a plurality of single-tooth sub-data, search the gingival morphology database for library-related data corresponding to each of the single-tooth sub-data, and construct a plurality of single-tooth features corresponding to each of the single-tooth sub-data using data overlap information between the library-related data and the single-tooth sub-data;

[0077] an optimization execution unit, configured to divide the plurality of single tooth features corresponding to each of the single tooth sub-data into regions based on the gum sampling data, determine the gingival margin area of ​​the patient, classify the gum sampling data above the gingival margin area as explicit data, and classify the gum sampling data below the gingival margin area as embedded data;

[0078] an abutment simulation unit, configured to construct a preliminary abutment shape of the patient according to the single tooth feature, perform appearance correction on the preliminary abutment shape using the explicit data, and perform embedded reinforcement on the preliminary abutment shape using the embedded data, to obtain an effective abutment shape of the patient;

[0079] A data conversion unit is used to determine the patient's abutment arrangement characteristics based on the outline of the effective abutment shape, convert the effective abutment shape into data description, reorganize several description data of the effective abutment shape, and generate the patient's abutment printing data.

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

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

[0082] In this example, the gingival margin area represents the junction between the gums and the tooth surface;

[0083] In this example, the external data refers to the external data of the patient's teeth, and the internal data refers to the embedded data inside the patient's gums.

[0084] The working principle and beneficial effects of the above technical solution: In order to better serve patients and provide them with beautiful and healthy dentures, the patient's gum sampling data is first divided into single-tooth sub-data, and then the relevant data is searched in the gum morphology database to construct the patient's single-tooth features. The position of the gingival margin area is further determined, and then the gum sampling data is divided into regions. The patient's preliminary abutment shape is constructed by using the single-tooth features, and the explicit data and embedded data obtained by the regional division are used to correct the preliminary abutment shape to construct the patient's effective abutment shape. According to the data presented by the effective abutment shape and its arrangement characteristics, in this way, not only can each single tooth be analyzed, but the shape of the abutment can also be adjusted according to actual conditions, forming an abutment that meets the patient's chewing needs, and at the same time generating printing data. At this time, the printing equipment can do the printing work in advance according to demand to improve subsequent printing efficiency.

[0085] Example 3:

[0086] On the basis of Example 1, the apparatus for batch printing dental crowns for implant abutments and the denture simulation module include:

[0087] a demand parsing unit, configured to perform decomposition training on the patient's proposed demand, determine a first association relationship between the proposed demand and the abutment arrangement feature, and a second association relationship between the proposed demand and the abutment printing data, and add a corresponding matching tag to the proposed demand;

[0088] a crown construction unit, configured to construct an initial crown shape for the patient based on the proposed requirements, determine a plurality of crown correction positions included in the initial crown shape according to the matching tags, determine a correction range of the initial crown shape according to the corresponding first association relationship, and determine a numerical range of the initial crown shape according to the second association relationship;

[0089] a crown correction unit, configured to correct the corresponding correction range based on the numerical range, obtain several crown shapes of the patient according to each correction result, and mark different points of the crowns between different crown shapes;

[0090] The data determination unit is used to obtain a target crown form with the least number of crown differences, perform data description on the target crown form, obtain crown printing data corresponding to the target crown form, adjust the crown printing data based on the crown differences between different crown forms, and obtain crown printing data corresponding to each crown form.

[0091] In this example, the first association relationship represents the relationship between the proposed requirements and the base station arrangement characteristics, and the second association relationship represents the relationship between the proposed requirements and the base station printing data;

[0092] In this example, the matching tag represents an identifier for matching the proposed requirements with the base arrangement features, and an identifier for matching the proposed requirements with the base printing data;

[0093] In this example, the correction range indicates the range of the initial crown shape that needs to be corrected, and the value range indicates the intensity value range of the correction of the initial crown shape.

[0094] The working principle and beneficial effects of the above technical solution: Since the needs of each patient are different and some patients have a low understanding of the oral field, multiple different crown shapes are provided to the patient before printing. First, the initial crown shape is constructed according to the patient's proposed needs, and then the initial crown shape is corrected and adjusted according to the first correlation between the proposed needs and the base arrangement characteristics and the second correlation between the proposed needs and the base printing data. The patient's crown shape is generated according to the correction result. In order to facilitate subsequent work, the crown differences between different crown shapes are screened in advance, and then data description is performed for the target crown shape with the least number of crown differences. The crown differences between different crown shapes are then used to adjust the obtained data to generate crown printing data for each crown shape. In this way, not only can a variety of crown shapes be provided to patients, but also the printing data can be determined, the printing efficiency of the printing equipment can be improved, and a good printing reference can be provided.

[0098] The key features of the tooth crown are clustered, and the tooth crown morphologies are sorted in descending order according to the number of cluster features, and a morphology recommendation order is generated and displayed.

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

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

[0106] The working principle and beneficial effects of the above technical solution: Using AI technology to analyze the facial beauty viewpoints and aesthetic influencing factors in the patient's facial contour can not only keep up with the current fashion trends but also provide patients with inspiration for crown selection. First, AI technology is used to analyze the patient's facial contour to determine their facial beauty viewpoints and aesthetic influencing factors. Then, the crown printing data is input into it for simulation and aesthetic evaluation. According to the generated aesthetic report, the impact of each facial simulation effect is determined, and then the facial simulation effects that meet the aesthetic requirements are screened, and the corresponding printing effects are constructed. Finally, the target crown printing data is determined according to the patient's needs. At the same time, a crown maintenance plan is provided to the patient, which is convenient for the patient to learn in advance and extend the service life of the denture.

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

[0113] The working principle and beneficial effects of the above technical solution are as follows: the execution conditions of this printing are constructed according to the abutment printing data and the target crown printing data. In order to avoid the phenomenon of misinstallation, the abutment and the crown are matched and coded before printing. After printing, the matching is carried out in time to obtain the patient's appearance effect for reference by the patient and the doctor, which 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.

[0117] The working principle and beneficial effects of the above technical solution: Since the gum conditions of some patients are relatively complicated, the patients require special treatment. At this time, the effects with the best implant effect but lower aesthetics will be selected for printing, giving priority to meeting the patient's good chewing needs.
