Description

A method for manufacturing a patient-specific dental indirect bonding tray, a dental simulator for creating a patient-specific indirect bonding tray for a patient and a related patient-specific virtual guide

The present invention relates to a method for manufacturing a patient-customized dental indirect bonding tray, a patient-customized dental indirect bonding tray, and a dental simulator for generating a patient-specific virtual guide related thereto.

In addition to direct bonding as a method for attaching conventional orthodontic devices (bracket, tube, etc.) to the correct position of the teeth, indirect bonding is attempted indirectly through a dental model simulating the examinee's teeth with plaster. ) is a way.

In direct bonding, a doctor had to use an adhesive to directly adhere to the teeth of an orthodontist, such as a metal, during orthodontic treatment, and then attach a thin line to this bracket to apply external force to move the teeth requiring correction to an appropriate position. In the case of direct bonding in this way, it takes a long time for the doctor to install each tooth individually, and depending on the skill of the doctor, the mounting position is jagged, making accurate correction difficult, which puts a great burden on the examinee as well as the doctor.

In order to alleviate this burden, an indirect bonding method has been developed. In the indirect bonding method, the inner side of the tray is adhered to the location corresponding to the position to be mounted on the examinee's teeth, the tray with the adhered bracket is appropriately placed on the examinee's teeth, and then the doctor applies pressure to the tray to apply pressure to the tray. It is to be adhered to the examinee's teeth. As described above, if the tray using the bracket is used, the doctor can mount the bracket on the examinee's teeth in a short time, thereby greatly reducing the burden on the dentist and the examinee.

On the other hand, recently, as beauty is emphasized during orthodontic treatment, there are cases where orthodontic treatment is performed by attaching orthodontic devices to the lingual side (lingual side) instead of using transparent braces or attaching an orthodontic device to the labial side (lip side).

In particular, the skill of the dentist is most important in order to see the orthodontic effect by attaching the lingual orthodontic appliance to the teeth. In particular, the lingual orthodontic appliance is more difficult to attach than the labial appliance, and The “orthodontic power” is greater than that of the labial orthodontic appliance. Accordingly, an appropriate guide was needed to fix the bracket of the labial orthodontic device to the examinee's teeth.

The present invention provides a method for manufacturing a patient-customized dental indirect bonding tray, a method for manufacturing a patient-customized dental indirect bonding tray, which is used to attach an orthodontic device more precisely and easily in attaching a lingual orthodontic device with emphasis on beauty during the orthodontic period. An object of the present invention is to provide a dental simulator for generating a bonding tray and a patient-customized virtual guide related thereto.

Here, the first bracket guide may be a guide formed on the outer periphery of the bracket, and the second bracket guide may be a guide formed on lingual surfaces of the bracket and the teeth.

Here, the manufacturing of the indirect bonding tray using the orthodontic model may include attaching actual brackets to the orthodontic model through the first and second bracket guides; and placing a flexible sheet on the orthodontic model to which the actual brackets are attached and then vacuum forming to manufacture the in-direct bonding tray.

Here, the step of generating the first virtual guide and the second virtual guide in the aligned three-dimensional tooth object data by using the virtual bracket is performed on the aligned three-dimensional tooth object data after the step of attaching the virtual bracket. The method may include generating the virtual guide or generating the first virtual guide and the second virtual guide in the aligned 3D tooth object data after the step of rearranging the virtual guide to the original position.

Here, the step of generating a first virtual guide and a second virtual guide in the aligned three-dimensional tooth object data using the virtual bracket includes generating the first virtual guide based on the base surface of the virtual bracket, It may include generating a second virtual guide based on the base surface of the first virtual bracket and the lingual surface of the teeth.

Here, the first virtual guide may include guide portions respectively corresponding to at least three sides of the base surface.

Here, in order to adjust the direction and force of the orthodontic force applied to the teeth, the second guide unit may be configured to have a different height.

Here, the manufacturing of the indirect bonding tray using the orthodontic model may include applying a resin to the base surface of the actual bracket; And press-molding the actual bracket to which the resin is applied on the orthodontic model may include the step of manufacturing the in-direction bonding tray.

2 to 16 are views for specifically explaining an embodiment of the present invention and a method for manufacturing a patient-customized dental indirect bonding tray.

17 is a view for explaining a simulator for generating first and second virtual guides related to an embodiment of the present invention;

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. These examples are provided to explain the present invention in more detail to those of ordinary skill in the art to which the present invention pertains.

Hereinafter, the case of installing the bracket on the lingual side, where it is relatively difficult to fix the bracket, will be described as an example, but the present invention does not

Referring to FIG. 1 , three-dimensional tooth object data for the examinee's teeth is obtained (S1). The dental image information may be obtained by obtaining a face image of the examinee through a 3D scanner or the like, or may be obtained through a medical image obtaining apparatus such as an X-ray. A plurality of three-dimensional tooth object data is obtained from the tooth image information.

Then, the three-dimensional tooth object data is aligned with the teeth after orthodontic treatment (S2). For example, alignment with the teeth after orthodontic treatment (also referred to as 'setup') may correspond to standard tooth information. The standard tooth information may be information about a tooth serving as a preset standard, or information about a tooth prepared by a specialist such as a doctor. As another example, alignment with the teeth after orthodontic treatment may be adjusted according to the situation or arbitrarily by a doctor or the like.

A lingual virtual bracket is attached to the aligned three-dimensional tooth object data (S3). The lingual bracket is attached to the back (lingual side) of the teeth, and when the teeth are straightened using the lingual bracket, it has the cosmetic effect of making the braces invisible to the outside and has the advantage of exerting stronger orthodontic power on individual teeth. On the other hand, it has disadvantages in that it is difficult to attach, and in case of misalignment, the orthodontic treatment is not properly performed. The lingual virtual bracket in the present invention for facilitating the attachment of such a lingual bracket may be attached to the aligned three-dimensional tooth object on the same line.

The aligned 3D dental object data to which the lingual virtual bracket is attached are rearranged to their original positions ('positions of 3D dental object data obtained from the examinee's teeth for the first time') (S4). Accordingly, it is possible to obtain virtual attached three-dimensional tooth object data for correct orthodontic treatment.

A virtual guide is created in the aligned three-dimensional tooth object data using the lingual virtual bracket (S5). For example, a first virtual guide and a second virtual guide are generated in the three-dimensional dental object data based on the base surface of the lingual virtual bracket attached to the three-dimensional dental object data (S5). Here, the base surface of the lingual virtual bracket means a surface where the virtual bracket and the rear surface (lingual surface) of the tooth image contact each other, and the side of the base surface means each line segment constituting the base surface. The first virtual guide means a frame that holds the standard so that the actual bracket can be attached to the correct position when attaching the actual bracket to the teeth, and the second virtual guide is the base surface of the bracket when the actual bracket is attached to the teeth. It refers to a molding that is attached to the lingual side of this tooth. At least one first virtual guide protrudes from the back of the tooth and may be formed. That is, the number of the first virtual guides is not limited. In addition, the second virtual guide may be formed in the center of the first virtual guides.

For example, the first virtual guide may include guide portions respectively corresponding to at least three sides of the base surface of the bracket.

For another example, the first virtual guide may include a guide portion having a “L” shape corresponding to at least two corners of the base surface of the bracket.

As another example, the first virtual guide may include a plurality of guide points formed at positions corresponding to the sides of the base surface of the bracket. The cross-section of the guide point may have various shapes, such as a circular shape, a semicircle shape, an elliptical shape, a polygonal shape, and the like.

The base surface of the second virtual guide has a curvature corresponding to the curvature of the base surface of the bracket, so that when the bracket is attached to the lingual surface of the tooth, it can be brought into close contact.

The step of generating the virtual guide on the aligned 3D tooth object data using the virtual bracket may be performed after the step of attaching the virtual bracket to the aligned 3D tooth object data.

Alternatively, the step of generating the first and second virtual guides in the three-dimensional dental object data aligned using the virtual bracket is to be performed after realigning the aligned three-dimensional dental object data to which the virtual bracket is attached to the original position. can

An orthodontic model corresponding to the three-dimensional tooth object data including the first and second virtual guides is produced (S6). In other words, the orthodontic model including the first bracket guide and the second bracket guide is manufactured using the aligned three-dimensional tooth object data including the first virtual guide and the second virtual guide. Here, the first bracket guide is a guide formed on the outer periphery of the bracket, and the second bracket guide is a guide formed on the lingual side of the bracket and the teeth.

An indirect bonding tray is manufactured using the orthodontic model manufactured in this way (S7). For example, an indirect bonding tray may be manufactured by being attached to an actual orthodontic model through the first and second bracket guides, and vacuum forming after placing a flexible sheet on the actually attached orthodontic model. Here, an actual ready-made product may be used. By manufacturing the indirect bonding tray using the flexible sheet as described above, the indirect bonding tray may be manufactured to have flexibility. In addition, when the second bracket guides have different heights as shown in FIGS. 10 to 12, a resin is applied to the base surface of the actual bracket, and then the actual bracket to which the resin is applied is pressed on the orthodontic model. By molding, the indirect bonding tray can be manufactured.

After the indirect bonding tray is manufactured, the process may include bonding to the actual indirect bonding tray, and forming an adhesive on the surface of the actual bracket in contact with the examinee's teeth. Thereafter, the doctor or the like may couple the in-direct bonding tray including the true bracket to the actual teeth of the examinee, and apply force to couple the bracket to the actual teeth.

In the method for manufacturing an indirect bonding tray for dental use according to the present invention, by manufacturing the indirect bonding tray using a flexible sheet, the indirect bonding tray may have flexibility. Therefore, when the doctor attaches the bracket to the lingual side of the tooth, it is possible to accurately attach the bracket without applying a lot of force, thereby preventing secondary damage to the patient's teeth and guaranteeing the desired orthodontic effect. In addition to being able to do it, the time for attaching the bracket can be shortened.

In addition, the method for manufacturing an indirect bonding tray for dental use according to the present invention produces an indirect bonding tray using a flexible sheet, and uses a ready-made product without separately producing a bracket, thereby reducing the production cost compared to the case of production with a 3D printer. can be significantly reduced.

2 to 13 are diagrams for specifically explaining a method of manufacturing a dental indirect bonding tray related to an embodiment of the present invention.

Referring to FIG. 2 , three-dimensional tooth object data 200 for the examinee's teeth is obtained. That is, information about the examinee's teeth before orthodontic treatment is acquired. The dental image information may be obtained by obtaining a face image of the examinee through a 3D scanner or the like, or may be obtained through a medical image obtaining apparatus such as an X-ray. A plurality of three-dimensional tooth object data is obtained from the tooth image information.

Referring to FIG. 3 , the three-dimensional tooth object data is aligned with the teeth after orthodontic treatment ( 300 ). For example, alignment to the teeth after orthodontic treatment (also referred to as 'setup') may correspond to standard tooth information. The standard tooth information may be information about a tooth serving as a preset standard, or information about a tooth prepared by a specialist such as a doctor. As another example, alignment with the teeth after orthodontic treatment may be adjusted according to the situation or arbitrarily by a doctor or the like. A lingual virtual bracket 310 may be attached to the aligned three-dimensional tooth object data.

Referring to FIG. 4 , the aligned 3D dental object data to which the lingual virtual bracket 310 is attached is rearranged to the original position 200 ('position of 3D dental object data obtained from the examinee's teeth for the first time'). . Finally, the doctor attaches the actual bracket to the position of the lingual virtual bracket included in the orthodontic three-dimensional tooth object data, and then proceeds with orthodontic treatment.

Referring to FIG. 5 , after rearranging the aligned 3D tooth object data to which the lingual virtual bracket is attached to the original position, first and second virtual guides are applied to the aligned 3D tooth object data using the lingual virtual bracket. Creates (410,420). In this embodiment, after rearranging the aligned 3D tooth object data to which the lingual virtual bracket 310 is attached to its original position, the first and It will be described based on the generation of the second

virtual guides

Referring to FIG. 6 , the first virtual guide may include guide portions 410 corresponding to at least three sides of the base surface of the bracket, respectively. Here, the cross-section of the guide part 410 may have a rectangular shape, and may be implemented in a form protruding from the tooth surface.

Referring to FIG. 7 , the first virtual guide may include a guide part 410 ′ having a “L” shape corresponding to at least two corners of the base surface of the bracket.

The first virtual guides may be implemented in the same shape or may be implemented in different shapes. Also, the number of the first virtual guides may be variously implemented by a user or a producer. As such, in addition to the virtual guides shown in FIGS. 6 to 9, virtual guides of various shapes capable of fixing the brackets in precise positions may be applied.

Meanwhile, the second virtual side 420 is formed inside the first virtual guide so that a gap does not occur between the lingual side of the examinee's teeth and the base surface of the bracket so that the force applied to the examinee's difference is sufficient to correct the teeth. It functions to transfer to the teeth. As shown in FIG. 6 , the second virtual guide 420 has a flat plate in the form of a right-angled rectangle or square as a whole, and the curvature of the upper surface may be configured to be the same as the curvature of the base surface of the bracket. In addition, the upper surface of the second virtual guide 420 may be configured to be inclined in one direction (eg, left, right, upper or lower) in order to adjust the direction and magnitude of the orthodontic force on the teeth.

Various examples of the second virtual guide 420 will be described with reference to FIGS. 10 to 12 . 10 and 12 , the first virtual guide 410 is formed in the form of a long bar on four sides to define a space of a right-angled quadrangle. This is merely an example, and it should be understood that the examples of FIGS. 7 to 9 may be used.

In order to adjust the direction and force of the orthodontic force applied to the second virtual guide unit, the second guide unit may have different heights, respectively.

Meanwhile, referring to FIG. 13 , the orthodontic model 500 including the bracket guide 510 is manufactured using the aligned three-dimensional tooth object data including the virtual guide.

Referring to FIG. 14 , the actual bracket 600 is attached to the inside of the bracket guide 510 formed in the orthodontic model 500 . For actual brackets, ready-made products can be used. In this way, by using a ready-made bracket for the bracket, it is possible to solve the problem of not being able to produce the bracket in a uniform and accurate desired shape by manufacturing the brackets one by one using a 3D printer.

Referring to FIG. 15 , an indirect bonding tray 700 is manufactured using the orthodontic model 500 . For example, an indirect bonding tray may be manufactured by vacuum forming after a real bracket is attached to an orthodontic model through a bracket guide, and a flexible sheet is placed on the orthodontic model to which the actual bracket is attached.

After the indirect bonding tray is manufactured, the method may include bonding an actual bracket to the indirect bonding tray, and forming an adhesive on a surface of the actual bracket in contact with the examinee's teeth. Thereafter, the doctor or the like may couple the indirect bonding tray including the bracket (adhesive agent formed) to the actual teeth of the examinee, and apply force to bond the bracket (adhesive agent formed) to the actual teeth.

Referring to FIG. 16 , the doctor puts the indirect bonding tray 700 on the examinee's actual teeth T, and applies force to the indirect bonding tray 700 to attach the bracket 600 to the actual teeth. 13, since the indirect bonding tray 700 has ductility and can be moved flexibly by an external force, the doctor can attach the bracket to the examinee without applying a lot of force to the patient's teeth. Not only can secondary damage be prevented, but also the time to attach the bracket can be shortened.
