Description

Technical Field

[0001] This disclosure relates to a method, apparatus, and storage medium for designing, selecting, distributing, performing minor surgery on, or providing related information about customized prefabricated abutments. Background Technology

[0002] An implant is a substitute for missing human tissue. In dentistry, an implant generally refers to a substitute for the tooth root (root) that is implanted and integrated into the alveolar bone after the natural tooth root has fallen out.

[0003] Dental implants can be classified in various ways based on how the artificial tooth is attached to the tooth root. One type is the bolt-type implant, which utilizes the locking force of a bolt. Existing bolt-type implant systems (implant assemblies) consist of the implant, abutment, and artificial tooth.

[0004] When performing dental implant surgery, the surgeon will select the appropriate product from implants or abutments of various diameters and pitches, taking into account the patient's oral condition.

[0005] In particular, in implant systems, the abutment located between the implant and the artificial tooth can take various shapes, depending on the condition of the implant placed in the jawbone or the condition of the patient's oral cavity.

[0006] Recently, a method has been proposed for manufacturing and using customized abutments tailored to individual patients using computer-aided design and manufacturing (CAD-CAM) methods, which do not use abutments provided in a finished product form.

[0007] Custom-made abutments are time-consuming and expensive because they are made to fit each individual tooth and gum. However, because they are designed to fit perfectly to the tooth and gum, they prevent food impaction and offer superior aesthetics. On the other hand, pre-fabricated abutments are mass-produced products that are delivered by the manufacturer. Due to mass production, they are readily available and inexpensive. However, pre-fabricated abutments may not fit the tooth and gum, potentially leading to food impaction or tooth dislocation. Summary of the Invention

Therefore, the terminology used in this disclosure should be defined according to the meaning of the terms and the overall content of this disclosure, and not merely as the names of the terms.

[0039] Throughout the specification, when a part is described as "including" a component, it indicates that other components may also be included, rather than excluding other components, unless otherwise stated. Furthermore, terms such as "...part" or "...module" used in the specification refer to units that perform at least one function or operation, which can be implemented by hardware or software, or a combination of hardware and software.

[0040] Throughout this specification, "support" can be broadly interpreted to include performing related operations to achieve a specific purpose, without being limited in meaning. Furthermore, throughout this specification, "provide" includes the process by which an object obtains specific information or directly or indirectly sends / receives information to a specific object, and can be understood as comprehensively including the execution of related operations required in these processes.

[0041] In the following detailed description, embodiments of the present disclosure will be given with reference to the accompanying drawings to enable those skilled in the art to readily implement the invention. However, the present disclosure can be implemented in various different forms and is not limited to the embodiments described herein.

[0042] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0043] Figure 1 This is a diagram illustrating the construction of a custom-designed finished base 100 according to one embodiment.

[0044] Reference Figure 1The custom-designed prefabricated abutment 100 may include: a post 110 located at the upper end for integration with the interior of the crown; a lower part 130 located at the lower end for integration with the implant in part or all of the lower part; and a gingival portion 120 located between the post 110 and the lower part 130 for contact with the gingiva without integration with the implant.

[0045] Customized prefabricated abutments 100 refer to prefabricated abutments with customized abutment shapes that have been statistically optimized for the oral environment of most patients.

[0046] The dimensions of the custom-made prefabricated abutment 100 can be determined according to various standards. For example, the dimensions of the custom-made prefabricated abutment 100 may include the horizontal and vertical lengths of the axial projection image of the abutment, the height of the gingival portion 120, and the height of the base portion 110, etc.

[0047] The custom-designed prefabricated abutment 100 can be defined according to various standards and measurements thereof. For example, the custom-designed prefabricated abutment 100 can be defined by the horizontal and vertical lengths of the axial projection image of the abutment, the height of the gingival portion 120, the height of the base portion 110, and the angle of the base portion 110, but is not limited thereto. The angle of the base portion 110 can be the angle between the base portion 110 and the gingival portion 120 or the angle between the base portion 110 and the lower portion 130.

[0048] The dimensions of the customized prefabricated abutment 100 or the angle of the base portion 110 can be determined based on the regional division results of the overall statistical distribution range of the patient-customized abutment. Here, regional division can be understood as a specific one or more local distribution ranges on a two-dimensional or one-dimensional distribution of statistical data.

[0049] According to one embodiment, multiple region division operations can be performed based on unit length, and the length difference between groups can be indicated by multiples of unit length.

[0050] According to one embodiment, the unit length range may include at least one of 0.5 mm, 0.75 mm, and 1.0 mm. Specifically, the horizontal and vertical length ranges of the axial projection image of the customized finished base 100 may include at least one of 0.5 mm, 0.75 mm, and 1.0 mm. For example, the unit length (or the horizontal and vertical lengths of the axial projection image) may correspond to at least one of 0.5 mm, 0.75 mm, and 1.0 mm. In this case, when the unit length corresponds to 0.5 mm, the unit length may be a value within a preset range (e.g., 0.1 mm, 0.01 mm, and 0.2 mm, etc.); when the unit length corresponds to 0.75 mm, the unit length may be a value within a preset range; and when the unit length corresponds to 1.0 mm, the unit length may be a value within a preset range, but is not limited thereto.

[0051] Regions can be divided for each tooth type, which may include at least one of maxillary incisors, mandibular incisors, canines, micromolars, and macromolars.

[0052] Figure 2 This is a diagram illustrating a method for determining the number of customized finished base stations 100 based on the division results of multiple regions according to one embodiment.

[0053] Reference Figure 2 According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be divided into multiple regions based on a unit length corresponding to 1.0 mm. At this time, the maxillary incisors can be divided into 4 regions (with a coverage rate of 96%), the mandibular incisors into 2 regions (with a coverage rate of 87%), the canines into 4 regions (with a coverage rate of 96%), the small molars into 2 regions (with a coverage rate of 97%), and the large molars into 4 regions (with a coverage rate of 95%). Therefore, the region division result of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be 16.

[0054] According to one embodiment, the statistical distribution range of the height of the gingival region 120 can be divided into multiple regions based on a unit length corresponding to 1.0 mm. In this case, the maxillary incisors can be divided into 5 regions, the mandibular incisors into 5 regions, the canines into 5 regions, the micromolars into 4 regions, and the molars into 4 regions.

[0055] According to one embodiment, the statistical distribution range of the height of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 1.0 mm. In this case, the maxillary incisors can be divided into 3 regions, the mandibular incisors into 3 regions, the canines into 3 regions, the small molars into 3 regions, and the large molars into 3 regions.

[0056] According to one embodiment, the statistical distribution range of the angle of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 12 degrees. At this time, the maxillary incisors can be divided into 2, the mandibular incisors can be divided into 2, the canines can be divided into 2, the small molars can be divided into 2 (or 1), and the large molars can be divided into 2 (or 1).

[0057] Therefore, the horizontal and vertical lengths of the maxillary incisors relative to the axial projection image are divided into 4 regions, the height relative to the gingival portion 120 is divided into 5 regions, the height relative to the abutment portion 110 is divided into 3 regions, and the angle relative to the abutment portion 110 is divided into 2 regions, resulting in a total of 120 region divisions. Thus, 120 custom-made prefabricated abutments 100 can be determined for the maxillary incisors. Similarly, 60 regions can be obtained for the mandibular incisors, 120 for the canines, 48 ​​for the micromolars, and 96 for the macromolars. Therefore, when the unit length corresponds to 1 mm and the unit angle corresponds to 12 degrees, 444 region divisions can be obtained.

[0058] According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be divided into multiple regions based on a unit length corresponding to 0.75 mm. At this time, the maxillary incisors can be divided into 6 regions (with a coverage rate of 94%), the mandibular incisors into 4 regions (with a coverage rate of 95%), the canines into 6 regions (with a coverage rate of 95%), the small molars into 4 regions (with a coverage rate of 90%), and the large molars into 6 regions (with a coverage rate of 90%). Therefore, the region division result of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be 26.

[0059] According to one embodiment, the statistical distribution range of the height of the gingival region 120 can be divided into multiple regions based on a unit length corresponding to 0.75 mm. In this case, the maxillary incisors can be divided into 5 regions, the mandibular incisors into 5 regions, the canines into 5 regions, the micromolars into 4 regions, and the molars into 4 regions.

[0060] According to one embodiment, the statistical distribution range of the height of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 0.75 mm. In this case, the maxillary incisors can be divided into 3 regions, the mandibular incisors into 3 regions, the canines into 3 regions, the small molars into 3 regions, and the large molars into 3 regions.

[0061] According to one embodiment, the statistical distribution range of the angle of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 12 degrees. At this time, the maxillary incisors can be divided into 2, the mandibular incisors can be divided into 2, the canines can be divided into 2, the small molars can be divided into 2 (or 1), and the large molars can be divided into 2 (or 1).

[0062] Therefore, the horizontal and vertical lengths of the maxillary incisors relative to the axial projection image are divided into 6 regions, the height relative to the gingival portion 120 is divided into 5 regions, the height relative to the abutment portion 110 is divided into 3 regions, and the angle relative to the abutment portion 110 is divided into 2 regions, resulting in a total of 180 region divisions. Thus, 180 custom-made prefabricated abutments 100 can be determined for the maxillary incisors. Similarly, 120 region divisions can be obtained for the mandibular incisors, 180 for the canines, 96 for the micromolars, and 144 for the macromolars. Therefore, when the unit length corresponds to 0.75 mm and the unit angle corresponds to 12 degrees, 720 region divisions can be obtained.

[0063] According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be divided into multiple regions based on a unit length corresponding to 0.5 mm. At this time, the maxillary incisors can be divided into 8 regions (coverage equivalent to 92%), the mandibular incisors into 6 regions (coverage equivalent to 91%), the canines into 8 regions (coverage equivalent to 90%), the small molars into 6 regions (coverage equivalent to 93%), and the large molars into 9 regions (coverage equivalent to 88%). Therefore, 37 region division results for the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be obtained.

[0064] According to one embodiment, the statistical distribution range of the height of the gingival region 120 can be divided into multiple regions based on a unit length corresponding to 0.5 mm. In this case, the maxillary incisors can be divided into 5 regions, the mandibular incisors into 5 regions, the canines into 5 regions, the micromolars into 4 regions, and the molars into 4 regions.

[0065] According to one embodiment, the statistical distribution range of the height of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 0.5 mm. In this case, the maxillary incisors can be divided into 3 regions, the mandibular incisors into 3 regions, the canines into 3 regions, the small molars into 3 regions, and the large molars into 3 regions.

[0066] According to one embodiment, the statistical distribution range of the angle of the base portion 110 can be divided into multiple regions based on a unit length corresponding to 12 degrees. At this time, the maxillary incisors can be divided into 2, the mandibular incisors can be divided into 2, the canines can be divided into 2, the small molars can be divided into 2 (or 1), and the large molars can be divided into 2 (or 1).

[0067] Therefore, the maxillary incisors can be divided into 8 regions based on their horizontal and vertical lengths relative to the axial projection image, 5 regions based on their height relative to the gingival portion 120, 3 regions based on their height relative to the abutment portion 110, and 2 regions based on their angle relative to the abutment portion 110, resulting in a total of 240 region divisions. Thus, 240 custom-made prefabricated abutments 100 can be determined for the maxillary incisors. Similarly, 180 regions can be obtained for the mandibular incisors, 240 for the canines, 144 for the micromolars, and 216 for the macromolars. Therefore, when the unit length corresponds to 0.5 mm and the unit angle corresponds to 12 degrees, 1020 region divisions can be obtained.

[0068] Reference Figure 2 When the unit length corresponds to 0.5mm, 0.75mm, and 1mm, and the unit angle corresponds to 12 degrees, 400 or more region division results can be obtained. (This is based on...) Figure 2 As can be seen from all the embodiments disclosed in the 0.5mm, 0.75mm, and 1mm models, the number of region division results (or the number of customized finished base stations) can be maintained at more than 400 in any case. The effect of a customized base station can only be expected from a finished base station when the number of region division results (or the number of customized finished base stations) reaches a predetermined level. According to this disclosure, all embodiments maintain a number of 400 or more region division results (or the number of customized finished base stations), therefore, even with a finished base station, the effect of a customized base station can be expected.

[0069] In order to use prefabricated base stations as custom base stations, minimum standards must be met, such as... Figure 2 As shown, by maintaining a minimum standard of 400, the effect of a customized base can be expected.

[0070] Figure 3 This is a schematic diagram illustrating an example of the configuration of a device 1000 according to one embodiment.

[0071] According to one embodiment, the device 1000 may include: a receiving unit 1100 that acquires at least 400 sets of customized prefabricated base plates based on a patient database; and a processor 1200 that picks up patient oral data, selects a suitable base plate from the sets of customized prefabricated base plates using software based on the picked-up patient oral data, and provides support for the delivery of the selected customized prefabricated base plate or for personnel performing minor surgeries.

[0072] According to another embodiment, the device 1000 may include: a receiving unit 1100 for acquiring patient oral data, the patient oral data including size information of the target tooth implantation space; and a processor 1200 for determining the number of multiple custom-made abutments to be at least 400 based on the number of regions obtained from the division of multiple regions of the statistical distribution range of the patient's custom-made abutments, and for determining suitable abutments among the multiple custom-made abutments and providing information on suitable abutments based on the tooth type of the target tooth and / or the size information of the target tooth implantation space. The tooth type may consist of maxillary incisors, mandibular incisors, canines, micromolars, and molars, but is not limited thereto. Furthermore, the tooth type can be selected using an automatic recommendation method implemented by software. For example, the device 1000 may use patient oral data including size information of the target tooth implantation space to provide recommendation information for any one of the maxillary incisors, mandibular incisors, canines, micromolars, and molars. Additionally, the tooth type may be selected based on user input regarding the recommendation information. The term "selected" may be interpreted to include, but is not limited to, a determined meaning.

[0073] Please refer to later Figures 4 to 17 A series of operations are described in another embodiment described above.

[0074] According to one embodiment, the receiving unit 1100 can receive information described in full in the specification from other devices, patient databases, or storage devices, such as wired / wireless communication devices capable of connecting to other devices via a network and sending / receiving various types of information described below. Furthermore, the processor 1200 can perform a series of operations, including designing, selecting, and distributing customized prefabricated basepieces, performing minor surgeries on customized prefabricated basepieces, or providing relevant information about customized prefabricated basepieces. This can be implemented by a central processing unit (CPU) controlling the overall operation of the device 1000 and is electrically connected to the receiving unit 1100 and other components to control the data flow between them.

[0075] Furthermore, those skilled in the art will understand that, in addition to Figure 3In addition to the components shown, device 1000 may also include other general-purpose components. For example, device 1000 may also include a patient database for storing patient data, a memory for storing data used throughout the operation, and an input / output interface for receiving user input or output information, etc.

[0076] Figure 4 This is a flowchart illustrating a method for designing, selecting, and distributing a custom-made abutment 100 or performing minor surgery on a custom-made abutment 100 using a device 1000 according to one embodiment, which designs or manufactures a plurality of custom-made prefabricated abutment groups based on a patient database.

[0077] Reference Figure 4 In step S410, device 1000 may include multiple custom-designed prefabricated abutment groups based on a patient database. In one embodiment, device 1000 may collect oral data from multiple patients and create a patient database including the oral data, or it may receive oral data from multiple patients from an already created patient database and analyze the statistical distribution of abutment data for each patient using the oral data, and perform region segmentation based on the analysis results to determine multiple custom-designed prefabricated abutment groups. For example, device 1000 may determine more than 400 custom-designed prefabricated abutment groups by dividing the overall statistical distribution into multiple regions.

[0078] In step S420, device 1000 may acquire patient oral cavity data. In one embodiment, device 1000 may generate patient oral cavity data including dimensional information of the implantation space of the target tooth through imaging, or acquire it from a user device, or receive it through user input. In one embodiment, patient oral cavity data may include 3D surface scan data.

[0079] In step S430, the device 1000 can use software to select a suitable abutment from multiple groups of custom-made prefabricated abutments based on the acquired patient oral data. For example, the device 1000 can determine the size information of a suitable patient-made abutment from the patient's oral data, or use the size information of the implantation space of the target tooth included in the oral data to determine a suitable abutment from more than 400 groups of custom-made prefabricated abutments obtained as a result of region segmentation.

[0080] In one embodiment, the device 1000 can determine a suitable abutment from multiple custom-made abutment groups based on the type of the target tooth and / or the size of the implantation space of the target tooth. For example, the device 1000 can determine the type of target tooth for which a minor surgery is required (e.g., maxillary incisor), the width of the target tooth implantation space (e.g., 0.75 mm), the height of the gingival portion 120, the height of the abutment portion 110, and the angle of the abutment portion 110 (e.g., 12 degrees) based on the patient's oral data, and select the corresponding one as the optimal abutment for the patient from more than 400 custom-made abutment groups.

[0081] In one embodiment, the device 1000 can obtain a virtual implantation result by simulating the implantation of a determined custom-made off-the-shelf abutment assembly into the patient's oral cavity data, and thereby determine whether the corresponding custom-made off-the-shelf abutment 100 fits the patient.

[0082] For example, in step S440, the device 1000 can deliver a selected custom-made prefabricated abutment 100 or perform a minor surgery. For instance, when it is determined that the abutment fits the patient, delivery of the custom-made prefabricated abutment 100 or the minor surgery can be supported by providing order information regarding the selected custom-made prefabricated abutment 100. Furthermore, upon receiving a user order request regarding the provided order information, the device 1000 can provide support to complete the delivery of the corresponding manufactured custom-made prefabricated abutment 100, thereby enabling the use of the custom-made prefabricated abutment 100 delivered to the user during the patient's minor surgery.

[0083] In one embodiment, when multiple custom-designed prefabricated base stations 100 are selected, the device 1000 provides information on the multiple selected custom-designed prefabricated base stations in a priority order, and can deliver the finally selected custom-designed prefabricated base station 100 or perform minor surgery based on selective input of one of the multiple custom-designed prefabricated base stations 100. For example, a base station recommendation catalog including relevant information of the selected custom-designed prefabricated base station 100 is displayed, and the custom-designed prefabricated base station 100 is finally selected based on user selection and input.

[0084] In one embodiment, when multiple custom-made abutments 100 are selected, different priorities can be assigned to the height of the gingival portion 120, the height of the base portion 110, and the angle of the base portion 110. For example, the closer the target is to the statistical average of the custom-made abutment group, the higher the priority can be assigned to the target in the order of the height of the gingival portion 120, the height of the base portion 110, and the angle of the base portion 110.

[0085] In one embodiment, device 1000 can acquire oral data from multiple patients and abutment data for patient-customized abutments associated with them. For example, device 1000 can derive abutment data including size information of patient-customized abutments suitable for the target teeth of each patient by analyzing and measuring the patients' oral data. As another example, patient oral data and patient-customized abutment data derived from minor surgeries performed on the patient or through measurement and analysis can be collected simultaneously.

[0086] In one embodiment, oral data can be measured using conventional impression methods or scanning, X-ray, CT, etc., and may include at least one of tooth type, location, gingival height, gingival shape, angle between tooth and alveolar bone, tooth size, and tooth diameter. In one embodiment, abutment data may include at least one of patient-specific prefabricated abutment type, size information, and corresponding tooth type. In one embodiment, for each patient, oral data and abutment data may be interconnected.

[0087] In one embodiment, the device 1000 can determine at least one parameter based on measured and analyzed data of the patient-customized abutment. For example, it can select parameters by analyzing oral data to determine the abutment data to be matched. As another example, it can receive user input of parts that the user considers important and select them as parameters. In one embodiment, at least one parameter may include the height of the base portion 110, gingival portion 120, and lower portion 130 of the aforementioned customized prefabricated abutment 100, the horizontal length, vertical length, angle, and other values ​​of the aforementioned factors, and at least one specific parameter may be selected according to a preset priority order or user input.

For example, as referred to Figure 1 and Figure 2The method described involves obtaining an axial projection image of a customized abutment for each patient and obtaining the horizontal and vertical lengths of the abutment from the projection image. A statistical distribution (e.g., a normal distribution) is derived for the horizontal and vertical lengths as they increase according to a preset unit length (e.g., 0.75 mm). Within the statistical distribution, intervals that meet preset conditions (e.g., 70% or more) are classified into a preset number (e.g., 5). This can be done by dividing the abutment into multiple regions. Based on the region division results, at least 400 customized prefabricated abutments are assembled using at least 26 customized prefabricated abutments 100 classified according to the horizontal and vertical lengths of the axial projection image of the abutment.

[0090] In one embodiment, the device 1000 can perform grouping for each tooth type, which may include at least one of maxillary incisors, mandibular incisors, canines, micromolars, and molars.

[0098] Reference Figures 8 to 10 According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be divided into multiple regions based on a unit length corresponding to 0.5 mm.

[0100] Reference Figures 14 to 16 According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 can be divided into multiple regions based on a unit length corresponding to 1.0 mm.

[0103] Reference Figure 17 In step S1710, the device 1000 can determine the number of customized prefabricated abutments based on the number of regions obtained from the division results of multiple regions of the statistical distribution range of the patient-customized abutment. In one embodiment, when the unit length of the horizontal and vertical lengths of the axial projection image of the customized prefabricated abutment 100 corresponds to 0.5 mm, 1020 regions can be obtained based on the region division results such as the height of the gingival portion 120, the height of the abutment portion 110, and the angle of the abutment portion 110; when the unit length corresponds to 0.75 mm, 720 regions can be obtained; and when it corresponds to 1.0 mm, 444 regions can be obtained. Referring to various embodiments, the number of regions obtained from the region division results can be 400 or more.

[0104] In one embodiment, the device 1000 performs grouping based on the statistical distribution range of abutment dimensions per unit length for each tooth type, and determines the number of multiple standard abutments to be at least 400 based on the sum of the number of groups obtained after performing grouping for each tooth type. According to one embodiment, the tooth type may include at least one of maxillary incisors, mandibular incisors, canines, micromolars, and macromolars.

[0105] In step S1720, device 1000 can obtain patient oral data including the size information of the implantation space for the target tooth. In one embodiment, patient oral data further including the target tooth type and the size information of the implantation space for the target tooth can be received from another device via user input.

[0106] In step S1730, the device 1000 can determine a suitable abutment from a plurality of custom-made prefabricated abutments based on the dimensional information of the implantation space of the target tooth. For example, the device 1000 can determine the type of target tooth for which a minor surgery is required (e.g., maxillary incisor), the width of the target tooth implantation space (e.g., 0.75 mm), the height of the gingival portion 120, the height of the abutment portion 110, and the angle of the abutment portion 110 (e.g., 12 degrees) based on the patient's oral data, and select the corresponding one as the optimal abutment for the patient from a group of more than 400 custom-made prefabricated abutments.
