Description

Method for manufacturing a patient-customized dental indirect bonding tray, a dental simulator for generating a patient-customized dental indirect bonding tray and a patient-customized virtual guide related thereto THE SAME, AND SIMULATOR FOR PRODUCING 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-customized virtual guide related thereto.

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

In direct bonding, a doctor directly attaches metal or the like to the teeth of an orthodontist using an adhesive during orthodontic treatment, and then applies an external force by hanging a thin wire to the bracket to move the tooth that needs orthodontic treatment to an appropriate position. In the case of direct bonding in this way, it takes a long time for the doctor to attach it to the entire tooth individually, and the attachment position is jagged depending on the doctor's skill level, making it difficult to correct it accurately.

In order to alleviate this burden, an indirect bonding method was developed. In the indirect bonding method, the tray is attached to the inside of the tray corresponding to the position to be mounted on the examinee's teeth, and the tray having the attached bracket is appropriately placed on the examinee's teeth, and then the doctor applies pressure to the tray to attach the tray. It is to adhere to the teeth of the examinee. In this way, if the tray using the bracket is used, the dentist can attach the bracket to the examinee's teeth in a short time, thereby greatly reducing the burden on the dentist and the examinee.

On the other hand, recently, with the importance of beauty during orthodontic period, there are cases in which correction is performed by attaching an orthodontic device to the lingual side (tongue side) instead of using a transparent brace or attaching the orthodontic device to the labial side (lip side).

In particular, the dentist's proficiency is the most important in order to fully see the orthodontic effect by attaching the lingual orthodontic appliance to the teeth. Especially in the case of the lingual orthodontic appliance, it is difficult to attach the orthodontic appliance compared to the labial orthodontic appliance, Orthodontic force" is greater than labial braces. Accordingly, an appropriate guide was required to place the bracket of the labial orthodontic device on the examinee's teeth.

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 embodiments are provided to explain the present invention in more detail to those skilled in the art to which the present invention pertains.

Hereinafter, a case in which the bracket is installed on the lingual side, where it is relatively difficult to fix the bracket, will be described by way of example, but the present invention is not limited thereto.

Referring to FIG. 1 , 3D tooth object data for the examinee's teeth is acquired (S1). Tooth image information may be obtained by acquiring a facial image of the examinee through a 3D scanner or the like, or may be acquired through a dedicated medical image acquisition device such as an X-ray. A plurality of three-dimensional tooth object data is acquired from tooth image information.

Then, the 3D tooth object data is aligned with the teeth after orthodontic treatment (S2). For example, alignment with teeth after orthodontic treatment (also referred to as 'set-up') may correspond to standard tooth information. The standard tooth information may be information about a standard tooth set in advance or information about a tooth prepared by an expert such as a doctor. For another example, the alignment of the teeth after orthodontic treatment may be adjusted according to circumstances or arbitrarily by a doctor or the like.

A lingual virtual bracket is attached to the aligned 3D tooth object data (S3). Lingual brackets are attached to the rear surface (lingual side) of teeth, and when orthodontic treatment is performed using lingual brackets, the braces have the cosmetic effect of being invisible and exhibit stronger orthodontic power for individual teeth. On the other hand, it has the disadvantage that it is difficult to attach and that orthodontic treatment is not performed properly when attached incorrectly. The lingual virtual bracket in the present invention for facilitating the attachment of such a lingual bracket may be attached to the aligned 3D tooth object on the same line.

The aligned 3D tooth object data to which the lingual virtual bracket is attached is rearranged to the original position ('the position of the 3D tooth object data initially obtained from the examinee's teeth') (S4). Accordingly, it is possible to obtain virtual attached 3D tooth object data for accurate correction.

A virtual guide is created in the aligned 3D tooth object data using the lingual virtual bracket (S5). For example, a first virtual guide and a second virtual guide are created in the 3D tooth object data based on the base surface of the lingual virtual bracket attached to the 3D tooth 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 come into contact, and the sides of the base surface mean each line segment forming 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 tooth, and the second virtual guide is the base surface of the bracket when attaching the actual bracket to the tooth. It means a molding to be attached to the lingual surface of the tooth. At least one first virtual guide protrudes from the rear surface of the tooth. That is, the number of first virtual guides is not limited. Also, the second virtual guide may be formed at the center of the first virtual guides.

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

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

As another example, the first virtual guide may include a plurality of guide points formed at positions corresponding to sides of the bracket base surface. The cross section of the guide point may have various shapes such as a circular shape, a semicircular 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 closely adhered to.

The step of generating a virtual guide to 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 aligned 3D tooth object data using the virtual brackets may be performed after rearranging the aligned 3D tooth object data to the original position to which the virtual brackets are attached. 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, an orthodontic model including a first bracket guide and a second bracket guide is manufactured using the aligned 3D 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 circumference of the bracket, and the second bracket guide is a guide formed on the lingual surface of the bracket and the tooth.

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

After the indirect bonding tray is manufactured, bonding to the actual indirect bonding tray and forming an adhesive on the surface of the actual bracket that comes into contact with the examinee's teeth may be included. Thereafter, the doctor or the like couples the indirect bonding tray including the actual brackets to the examinee's real teeth, and applies force to couple the brackets to the real teeth.

In the method for manufacturing an indirect bonding tray for dental use according to the present invention, the indirect bonding tray can be made flexible by manufacturing the indirect bonding tray using a flexible sheet. Therefore, when attaching the bracket to the lingual side of the tooth, the doctor can accurately attach the bracket without applying much force, preventing secondary damage to the patient's teeth and ensuring the orthodontic effect desired by the doctor. In addition, 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 production costs compared to the case of producing with a 3D printer. can be significantly reduced.

2 to 13 are views for explaining in detail a method of manufacturing an indirect bonding tray for dental use related to an embodiment of the present invention.

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

Referring to FIG. 3 , 3D tooth object data is aligned (300) with the teeth after orthodontic treatment. For example, alignment with teeth after orthodontic treatment (also referred to as 'setup') may correspond to standard tooth information. The standard tooth information may be information about a standard tooth set in advance or information about a tooth prepared by an expert such as a doctor. For another example, the alignment of the teeth after orthodontic treatment may be adjusted according to circumstances or arbitrarily by a doctor or the like. The lingual virtual bracket 310 may be attached to the aligned 3D tooth object data.

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

Referring to FIG. 5, after rearranging the aligned 3D tooth object data to the original position to which the lingual virtual brackets are attached, first and second virtual guides are applied to the aligned 3D tooth object data using the lingual virtual brackets. yields (410,420). In this embodiment, after the aligned 3D tooth object data to which the lingual virtual brackets 310 are attached are rearranged to their original positions, the aligned 3D tooth object data using the lingual virtual brackets 310 are subjected to first and second tooth object data. It will be described based on generating the second virtual guides 410 and 420 . However, after the step of attaching the lingual virtual bracket to the aligned 3D tooth object data, first and second virtual guides may be created on the aligned 3D tooth object data using the virtual bracket.

6 to 9 are views for explaining in detail the shape of the first virtual guide of the present invention.

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

Referring to FIG. 7 , the first virtual guide may include guide parts 410' shaped like "L" corresponding to at least two corners of the base surface of the bracket.

Referring to FIG. 9 , the first virtual guide may include a plurality of guide points 410"' formed at positions corresponding to sides of the base surface. Here, the plurality of guide points 410"' The cross section may have a square shape.

The first virtual guide may be implemented in the same shape or different shapes. Also, the number of first virtual guides may be variously implemented by users or manufacturers. In this way, in addition to the virtual guides shown in FIGS. 6 to 9 , virtual guides of various shapes capable of fixing the bracket to an accurate position may be applied.

On the other hand, the second virtual side 420 is formed inside the first virtual guide so that a gap does not occur between the lingual surface of the examinee's teeth and the base surface of the bracket, so that the force applied to the difference between the examinee's teeth is sufficiently applied to correct the teeth. It functions to be delivered to the teeth. As shown in FIG. 6 , the second virtual guide 420 has a rectangular or square flat plate as a whole, and the curvature of its upper surface may 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 inclined in one direction (eg, left, right, upper or lower) in order to adjust the direction and size 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 is formed of a first virtual guide part 410' having a long bar shape on four sides to define a rectangular space. It should be understood that this is only one example and that the examples of FIGS. 7 to 9 may be used.

Meanwhile, each of the second guide parts 420', 420", and 420"' constituting the second virtual guide may have different heights in order to adjust the direction and force of the orthodontic force applied to the teeth.

Meanwhile, referring to FIG. 13 , an orthodontic model 500 including a bracket guide 510 is manufactured using aligned 3D tooth object data including a virtual guide.

14, the actual bracket 600 is attached to the inside of the bracket guide 510 formed on the orthodontic model 500. Actual brackets can be used off-the-shelf. In this way, by using ready-made brackets, it is possible to solve the problem of not being able to manufacture brackets in a constant and accurate desired shape by individually manufacturing brackets using a 3D printer.

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

After the indirect bonding tray is manufactured, a process of bonding an actual bracket to the indirect bonding tray and forming an adhesive on a surface of the actual bracket that comes into contact with the examinee's teeth may be included. Thereafter, the doctor or the like may couple the indirect bonding tray including the brackets (on which the adhesive is formed) to the actual teeth of the examinee, and apply force so that the brackets (on which the adhesive is formed) are coupled to the actual teeth.

Referring to FIG. 16 , a doctor may attach an indirect bonding tray 700 to an examinee's real tooth T, and apply force to the indirect bonding tray 700 to attach a bracket 600 to the real tooth.
