Description

TECHNICAL FIELD

[0001] The present disclosure relates to a customized finished abutment. BACKGROUND

[0002] An implant refers to a substitute for repairing a missing human tissue, and in dentistry, it generally refers to a substitute for a tooth root (root portion) implanted and combined to a jawbone after a natural tooth root is lost to replace a missing tooth.

[0003] According to a method of combining an artificial tooth to a tooth root, the dental implant can be classified in various ways. Among them, there is a bolt-type implant using the locking force of a bolt, and the existing bolt-type implant system (implant assembly) is composed of an implant, an abutment, and an artificial tooth.

[0004] In performing a dental implant surgery, a practitioner selects a suitable product from among products having various diameters and pitches of implants or abutments, etc. and performs a surgery.

[0005] In particular, in the implant system, the abutment located between the implant implanted into the alveolar bone and the artificial tooth can adopt various shapes according to the state of the implant implanted in the jawbone or the state of the inside of the patient's mouth, etc.

[0006] Recently, a method of manufacturing and using a customized abutment suitable for an individual patient in a computer-aided design and manufacturing (CAD-CAM) manner without using an abutment provided in a finished product has been proposed. Since the customized abutment needs to be individually tailored for an individual, it takes a long time to manufacture and is expensive. However, since the customized abutment is manufactured to well fit the artificial tooth and the gum, it can prevent food impaction and is excellent in terms of aesthetics. On the other hand, the finished abutment is a mass-produced product that is collected and used by a manufacturer in a distribution manner, and has the advantages of being collected in a short time and being inexpensive due to mass production. However, the finished abutment can not fit the artificial tooth and the gum, and thus there can be a problem of food impaction or tooth displacement. SUMMARY

[0007] TECHNICAL PROBLEM

[0008] The present disclosure can provide a customized finished abutment. In particular, the present disclosure can provide an abutment having advantages of both a customized abutment and a finished abutment.

[0009] The technical problem to be solved is not limited to the above-described technical problem, and can include various technical problems within the scope obvious to those skilled in the art.

[0010] TECHNICAL SOLUTION

[0011] The first aspect of the present disclosure can provide a customized finished abutment including a post at an upper end so as to be combined with an inner portion of a crown, a lower portion at a lower end so that a part or all of the lower portion is combined with an implant, and a gingival portion between the post and the lower portion so as to contact a gum without being combined with the implant, wherein the customized finished abutment is designed and manufactured in a plurality such that a coverage rate of each group after grouping all teeth of an upper jaw and a lower jaw into upper incisors, lower incisors, canines, premolars, and molars reaches 65% or more based on a patient customized abutment.

[0012] Also, the customized finished abutment is designed and manufactured in a plurality such that a coverage rate of each group after grouping all teeth of the upper jaw and the lower jaw into the upper incisors, the lower incisors, the canines, the premolars, and the molars reaches 65% or more based on a statistical data of the patient customized abutment.

[0013] In addition, when the type of the tooth is the premolar and the unit length corresponds to 0.5㎜, a statistical distribution range determined from horizontal and vertical lengths of an axial projection image of the abutment is divided into 9 regions, and a coverage rate for the 9 regions can reach 85% or more.

[0014] In addition, when the type of the tooth is the premolar and the unit length corresponds to 0.5㎜, a statistical distribution range determined from horizontal and vertical lengths of an axial projection image of the abutment is divided into 7 regions, and a coverage rate for the 7 regions can reach 75% or more.

[0015] In addition, when the type of the tooth is the premolar and the unit length corresponds to 0.5㎜, a statistical distribution range determined from horizontal and vertical lengths of an axial projection image of the abutment is divided into 5 regions, and a coverage rate for the 5 regions can reach 65% or more.

[0016] In addition, when the type of the tooth is the premolar and the unit length corresponds to 0.5㎜, a statistical distribution range determined from horizontal and vertical lengths of an axial projection image of the abutment is divided into 9 regions, and a coverage rate for the 9 regions can reach 90% or more.

[0017] In addition, when the type of the tooth is the premolar and the unit length corresponds to 0.5㎜, a statistical distribution range determined from horizontal and vertical lengths of an axial projection image of the abutment is divided into 7 regions, and a coverage rate for the 7 regions can reach 80% or more.

[0018] In addition, when the type of the tooth is a small premolar and the unit length corresponds to 0.5 mm, a statistical distribution range determined based on horizontal and vertical lengths of an axial projection image of an abutment is divided into 5 regions, and a coverage ratio for the 5 regions can reach 65% or more.

[0019] A second aspect of the disclosure can provide a customized finished abutment including a post located at an upper end so as to be combined with an inside of a crown, a lower portion located at a lower end so that a part or all of the lower portion is combined with an implant, and a gingival portion located between the post and the lower portion so as to contact a gum without being combined with the implant, wherein at least one of horizontal and vertical lengths of an axial projection image of the abutment, a height of the gingival portion, a height of the post, and an angle of the post are determined by normalizing a result of dividing a statistical distribution range of a customized abutment of a patient into a plurality of regions.

[0020] In addition, a number of the customized finished abutment is determined based on performing unit length and / or unit angle-based grouping on the statistical distribution range for each type of tooth, which can include at least one of an upper incisor, a lower incisor, a canine, a small premolar, and a large premolar, and based on a sum of a number of groups obtained after the performing.

[0021] In addition, as the unit length is determined to be greater than or equal to 0.4 mm and less than 1.1 mm, a number of the customized finished abutment for the upper incisor can be determined to be greater than or equal to 4 and less than 9 based on the horizontal and vertical lengths, a number of the customized finished abutment for the lower incisor can be determined to be greater than or equal to 2 and less than 7 based on the horizontal and vertical lengths, a number of the customized finished abutment for the canine can be determined to be greater than or equal to 4 and less than 9 based on the horizontal and vertical lengths, a number of the customized finished abutment for the small premolar can be determined to be greater than or equal to 2 and less than 7 based on the horizontal and vertical lengths, and a number of the customized finished abutment for the large premolar can be determined to be greater than or equal to 4 and less than 10 based on the horizontal and vertical lengths.

[0033] The terminology used in the embodiments has been selected as widely used and common terms as possible while taking into account the functionality of this disclosure. However, these terms may be changed based on the intent or precedent of those skilled in the art, the emergence of new technologies, etc. In addition, in certain cases, terms may be arbitrarily chosen by the applicant, the meaning of which will be explained in detail in the 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.

[0034] In the entire instruction manual, 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.

[0035] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so as to be easily carried out by one of ordinary skill in the art to which the present disclosure pertains. However, the present disclosure can be implemented in various different forms and is not limited to the embodiments described herein.

[0036] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0037] Figure 1 is a diagram for explaining the configuration of a customized finished abutment 100 according to an embodiment.

[0038] Referring to Figure 1 , the customized finished abutment 100 can include a post 110 located at an upper end so as to be combined with the inside of a crown, a lower part 130 located at a lower end so that a part or all of the lower part is combined with an implant, and a gingival part 120 located between the post 110 and the lower part 130 so as to contact a gum without being combined with the implant.

[0039] The customized finished abutment 100 refers to a finished abutment having a customized abutment shape that is statistically optimized for the oral environment of a majority of patients.

[0040] The size of the customized finished abutment 100 can be determined according to various criteria. For example, the size of the customized finished abutment 100 can include the horizontal and vertical lengths of the axial projection image of the abutment, the height of the gingival part 120, and the height of the post 110, etc.

[0041] The customized finished abutment 100 can be defined according to various criteria and measured values thereof. For example, the customized finished abutment 100 can be defined by the horizontal and vertical lengths of the axial projection image of the abutment, the height of the gingival part 120, the height of the post 110, and the angle of the post 110, etc., but is not limited thereto. The angle of the post 110 can be the angle between the post 110 and the gingival part 120 or the angle between the post 110 and the lower part 130.

[0042] The size of the customized finished abutment 100 or the angle of the post 110 can be determined according to the results of the division of the area for the overall statistical distribution range of the customized abutment for a patient. Among them, the division of the area can be understood as a specific one or more local distribution ranges on a two-dimensional distribution or a one-dimensional distribution of statistical data.

[0043] According to an embodiment, the division of the area can be performed based on a unit length, and the length difference between the groups can be shown by a multiple of the unit length.

[0044] According to an embodiment, the range of unit length can include at least one of 0.5㎜, 0.75㎜, and 1.0㎜. For example, the unit length can correspond to at least one of 0.5㎜, 0.75㎜, and 1.0㎜. At this time, when the unit length corresponds to 0.5㎜, the unit length can be a value within 0.5㎜ to a preset range (e.g., 0.1㎜, 0.01㎜, 0.2㎜, etc.), when the unit length corresponds to 0.75㎜, the unit length can be a value within 0.75㎜ to a preset range, and when the unit length corresponds to 1.0㎜, the unit length can be a value within 1.0㎜ to a preset range, but is not limited thereto.

[0045] According to an embodiment, grouping can be performed for each tooth type, and the grouping of the region division results of the statistical distribution range can be performed according to each tooth type, and the tooth type can include at least one of an upper incisor, a lower incisor, a canine, a small premolar, and a large premolar.

[0046] According to an embodiment, at least one of the horizontal and vertical lengths of the axial projection image of the customized finished abutment 100, the height of the gingival part 120, the height of the base part 110, and the angle of the base part 110 can be determined by normalizing the plurality of region division results of the statistical distribution range of the patient customized abutment. The groups determined according to the region division can be determined to ensure the widest possible coverage of the overall statistical distribution range of the patient customized abutment. Among them, the coverage can refer to the ratio of the number of patient customized abutments belonging to the division region to the total number of patient customized abutments included in the overall statistical distribution range of the patient customized abutment. For example, the region division result that makes the coverage of each region greater than or equal to a preset value and maximizes the coverage of the entire region can be obtained by the region division, and as each group corresponding to each region is determined, the wide coverage for the overall statistical distribution range can be ensured. By normalizing the region division result as described above, the customized finished abutment 100 can be obtained. Specifically, the horizontal and vertical lengths of the axial projection image of the customized finished abutment 100, the height of the gingival part 120, the height of the base part 110, and the angle of the base part 110, etc. can be determined according to the normalization.

[0047] The number of the customized finished abutment 100 according to an embodiment can be determined based on the grouping based on the unit length and / or the unit angle performed for each tooth type according to the sum of the number of groups obtained after the performance, and specific embodiments thereof can refer to Figure 2 . In addition, the tooth type can include at least one of an upper incisor, a lower incisor, a canine, a small premolar, and a large premolar.

[0048] According to one embodiment, all teeth in the maxilla and mandible are grouped into maxillary incisors, mandibular incisors, canines, micromolars, and molars, and multiple custom-made prefabricated abutments 100 can be designed and manufactured such that the coverage of each group reaches more than 65% based on the patient-customized abutment. The tooth type of all teeth in the maxilla and mandible can be determined based on the tooth position, and the target tooth can be identified (or grouped) as any one of maxillary incisors, mandibular incisors, canines, micromolars, and molars based on the tooth position. Alternatively, the tooth type indicated by the tooth position can be identified (or grouped) as any one of maxillary incisors, mandibular incisors, canines, micromolars, and molars.

[0049] According to one embodiment, multiple custom-made abutments 100 can be designed and manufactured such that the coverage of each group after grouping all teeth of the maxilla and mandible into maxillary incisors, mandibular incisors, canines, micromolars, and molars reaches more than 65% of the patient-customized abutment based on statistical data of the patient-customized abutment. For example, multiple custom-made abutments 100 can be obtained for each of the maxillary and mandibular incisors, mandibular incisors, canines, micromolars, and molars. As an example, n (n is a positive integer, typically a number between 2 and 9) custom-made abutments 100 can be defined for molars based on the regional division results of the horizontal and vertical lengths of the axial projection image of the custom-made abutment 100. Furthermore, each group (or each tooth type) can be grouped based on statistical data of the patient-customized abutment, and the coverage of the patient-customized abutment can reach more than 65%. See below for further details. Figures 11 to 25 Describes several embodiments in which coverage is maintained above 65%.

[0050] 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.

[0051] 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 result of dividing the axial projection image of the customized prefabricated abutment 100 into 16 regions in terms of horizontal and vertical lengths can be achieved.

[0052] According to one embodiment, the statistical distribution range for the height of the gingival portion 120 can be divided into a plurality of regions based on a unit length corresponding to 1.0㎜. At this time, the upper incisors can be divided into 5, the lower incisors can be divided into 5, the canines can be divided into 5, the premolars can be divided into 4, and the molars can be divided into 4.

[0055] Accordingly, the horizontal and vertical lengths of the upper incisors with respect to the axial projection image are divided into 4, the heights of the gingival portion 120 are divided into 5, the heights of the base portion 110 are divided into 3, and the angles of the base portion 110 are divided into 2 regions, so a total of 120 region division results can be obtained. Accordingly, 120 custom-made abutments 100 can be determined for the upper incisors. In a similar manner, 60 region division results can be obtained for the lower incisors, 120 for the canines, 48 for the premolars, and 96 for the molars. Accordingly, when the unit length corresponds to 1㎜ and the unit angle corresponds to 12 degrees, 444 region division results can be obtained.

[0056] According to one embodiment, the statistical distribution range for the horizontal and vertical lengths of the axial projection image of the custom-made abutment 100 can be divided into a plurality of regions based on a unit length corresponding to 0.75㎜. At this time, the upper incisors can be divided into 6 (at this time, the coverage rate is equivalent to 94%), the lower incisors can be divided into 4 (at this time, the coverage rate is equivalent to 95%), the canines can be divided into 6 (at this time, the coverage rate is equivalent to 95%), the premolars can be divided into 4 (at this time, the coverage rate is equivalent to 90%), and the molars can be divided into 6 (at this time, the coverage rate is equivalent to 90%).

[0057] According to one embodiment, the statistical distribution range for the height of the gingival portion 120 can be divided into a plurality of regions based on a unit length corresponding to 0.75㎜. At this time, the upper incisors can be divided into 5, the lower incisors can be divided into 5, the canines can be divided into 5, the premolars can be divided into 4, and the molars can be divided into 4.

[0058] According to one embodiment, the statistical distribution range for the height of the base portion 110 can be divided into a plurality of regions based on a unit length corresponding to 0.75㎜. At this time, the upper incisors can be divided into 3, the lower incisors can be divided into 3, the canines can be divided into 3, the premolars can be divided into 3, and the molars can be divided into 3.

[0059] According to one embodiment, the statistical distribution range for the angle of the base portion 110 can be divided into a plurality of regions based on a unit length corresponding to 12 degrees. At this time, the upper incisors can be divided into 2, the lower incisors can be divided into 2, the canines can be divided into 2, the premolars can be divided into 2 (or 1), and the molars can be divided into 2 (or 1).

[0060] Accordingly, the horizontal and vertical lengths of the upper incisors with respect to the axial projection image are divided into 6, the heights of the gingival portion 120 are divided into 5, the heights of the base portion 110 are divided into 3, and the angles of the base portion 110 are divided into 2 regions, so a total of 180 region division results can be obtained. Accordingly, 180 custom-made abutments 100 can be determined for the upper incisors. In a similar manner, 120 region division results can be obtained for the lower incisors, 180 for the canines, 96 for the premolars, and 144 for the molars. Accordingly, when the unit length corresponds to 0.75㎜ and the unit angle corresponds to 12 degrees, 720 region division results can be obtained.

[0061] According to one embodiment, the statistical distribution range for the horizontal and vertical lengths of the custom-made abutment 100 with respect to the axial projection image can be divided into a plurality of regions based on a unit length corresponding to 0.5㎜, for example. At this time, the upper incisors can be divided into 8 (at this time, the coverage rate is equivalent to 92%), the lower incisors can be divided into 6 (at this time, the coverage rate is equivalent to 91%), the canines can be divided into 8 (at this time, the coverage rate is equivalent to 90%), the premolars can be divided into 6 (at this time, the coverage rate is equivalent to 93%), and the molars can be divided into 9 (at this time, the coverage rate is equivalent to 88%). Accordingly, the region division results for the horizontal and vertical lengths of the custom-made abutment 100 with respect to the axial projection image can be 37.

[0062] According to one embodiment, the statistical distribution range of the height of the gingival portion 120 can be divided into a plurality of regions, for example, based on a unit length corresponding to 0.5㎜. At this time, the upper incisors can be divided into 5, the lower incisors can be divided into 5, the canines can be divided into 5, the premolars can be divided into 4, and the molars can be divided into 4.

[0063] According to one embodiment, the statistical distribution range of the height of the base portion 110 can be divided into a plurality of regions, for example, based on a unit length corresponding to 0.5㎜.

In a similar manner, 180 region division results can be obtained for the lower incisors, 240 region division results can be obtained for the canines, 144 region division results can be obtained for the premolars, and 216 region division results can be obtained for the molars. Accordingly, when the unit length corresponds to 0.5㎜ and the unit angle corresponds to 12 degrees, 1020 region division results can be obtained.

[0066] Referring to Figure 2 When the unit length corresponds to 0.5㎜, 0.75㎜, and 1㎜ and the unit angle corresponds to 12 degrees, 400 or more region division results can be obtained.

[0072] Referring to Figure 5 , according to an embodiment, the statistical distribution range of the angle of the base portion 110 of the customized finished abutment 100 is divided into a plurality of regions based on a preset unit length (for example, 12 degrees), and the region division result can be grouped according to the subgroup of each tooth type. At this time, the maxillary incisors can be divided into 2 groups (at this time, the coverage rate is equivalent to 88%), the mandibular incisors can be divided into 2 groups (at this time, the coverage rate is equivalent to 85%), the canines can be divided into 2 groups (at this time, the coverage rate is equivalent to 91%), the premolars can be divided into 1 group (at this time, the coverage rate is equivalent to 83%), and the molars can be divided into 1 group (at this time, the coverage rate is equivalent to 68%).

[0073] Referring to Figures 6 to 7According to one embodiment, the statistical distribution range of the horizontal and vertical lengths of the axial projection image of the custom-type finished base 100 can be divided into a plurality of regions based on a unit length corresponding to 0.75㎜.

[0074] Referring to 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 custom-type finished base 100 can be divided into a plurality of regions based on a unit length corresponding to 1.0㎜. At this time, the upper incisors are divided into 4, thereby ensuring a coverage rate of 96%; the lower incisors are divided into 2, thereby ensuring a coverage rate of 87%; the canines are divided into 4, thereby ensuring a coverage rate of 96%; the premolars are divided into 4, thereby ensuring a coverage rate of 97%; and the molars are divided into 4, thereby ensuring a coverage rate of 95%.
