Description

Technical Field

[0001] The present invention relates to transparent aligners for orthodontics, and more particularly to a method and program for designing transparent aligners using a computer.

[0002] Specifically, the present invention relates to a program for designing a transparent aligner that optimizes the correction of target teeth by scanning the patient's oral structure with a 3D scanner, generating and saving treatment image information, and displaying the stored tooth image together with the designed transparent aligner.

[0003] The process of directly manufacturing transparent aligners with a 3D printer can be divided into two stages: the first stage is the set-up stage of moving the target teeth to the desired position, and the second stage is the stage of designing the transparent aligners based on each of the above set-up stages.

[0004] Provided by the present invention is a procedure for designing a transparent aligner for each stage of mobile setup. Background Art

[0005] The existing method for manufacturing a dental brace is as follows: First, the operator needs to understand the patient's oral structure and then make a dental model that is the same shape as the teeth. The patient's dental model is usually made by making a mold of the oral structure and casting it with materials such as plaster.

[0006] Next, a sheet of polyol material is used and pressed up and down at high temperature using a molding machine to produce a transparent aligner that fits the patient. This is the traditional production method.

[0007] However, this manufacturing method requires collaboration between doctors and dental technicians and manual operations, usually performed by skilled dental technicians, so the process is time-consuming and labor-intensive, resulting in increased manufacturing costs for dental braces.

[0008] In recent years, more and more dental clinics have begun to use 3D scanners to scan patients' oral structures, save this information and make tooth models based on it. This method is more advanced than the traditional method of directly taking impressions to make tooth models.

[0009] Specifically, the dental clinic can transmit the patient's oral 3D scan data to the dental laboratory, which will make a tooth model based on the received data and make transparent aligners based on this model.

[0010] The above methods all require making a tooth model first, and then making the orthodontic appliance based on the model. However, the present invention is different in that it uses 3D printing technology to directly output the orthodontic appliance, so no tooth model is required.

[0011] The present invention relates to a process for designing transparent aligners for direct production using a 3D printer. Summary of the invention

[0012] Technical issues The computer-designed transparent braces program described in the present invention is intended to significantly reduce the manufacturing time and manual workload of the dental braces by directly outputting the dental braces using a 3D printer without the need to make a separate tooth model, thereby significantly reducing the manufacturing cost of the dental braces.

[0013] In addition, the computer-designed transparent aligner program described in the present invention is intended to avoid the cumbersome cooperation process between dental clinics and dental laboratories, allowing dental clinics to directly manufacture aligners, thereby simplifying the aligner manufacturing process.

[0014] Furthermore, the computer-designed transparent corrector program described in the present invention is intended to provide optimal corrective force for each corrector setting stage, specifically by optimizing the shape, thickness, and medial side spacing of the transparent corrector, thereby improving the comfort and practicality of the transparent corrector produced using a 3D printer.

[0015] The computer program for designing transparent aligners described in the present invention overlaps the image of the transparent aligner with the image of the patient's tooth arrangement (hereinafter referred to as "dentition") at each movement setup stage of the target teeth for correction, and designs the transparent aligner in this state, thereby achieving more accurate and convenient transparent aligner production. This is the technical problem to be solved by the present invention.

[0016] Technical Solution In order to solve the above technical problems, the present invention proposes the following technical solutions: First, design it by following these steps: Step S01: Generate and store a plurality of dentition images after the target teeth are moved and set in sequence at each correction stage.

[0017] Step S02: randomly displaying one of the multiple dental images.

[0018] Step S03: In the displayed dental image, in order to determine the overall shape of the transparent aligner, a transverse reference line of each tooth is set and displayed.

[0019] Step S04: Starting from the reference line, set it toward the gums with a fixed value, and display the cutting line of the transparent aligner, that is, the edge line of the aligner.

[0020] Step S05: According to the cutting line set in step S04, a first treatment image reflecting a transparent aligner covering the upper dentition and the lower dentition is displayed, and the aligner is in a semi-transparent state.

[0021] Step S06: Input the overall gap value between the dentition and the transparent aligner.

[0022] Step S07: Generate and display a new second treatment image according to the gap value input in step S06.

[0023] Step S08: Select the tooth that needs to be corrected, and adjust the gap between the inner side of the transparent corrector and the selected tooth to be smaller than the gap value input in step S06.

[0024] Step S09: Generate and display a new third treatment image according to the gap value adjusted in step S08.

[0025] Step S10: Input the overall thickness value of the transparent aligner.

[0026] Step S11: Generate and display a new fourth treatment image according to the thickness value input in step S10.

[0027] Step S12: Select the tooth to be corrected again, and adjust the contact portion between the inner side of the transparent corrector and the selected tooth to a thickness greater than the value input in step S10.

[0028] Step S13: Generate and display a new fifth treatment image according to the thickness value adjusted in step S12.

[0029] Step S14: Save the fifth treatment image generated in step S13.

[0030] Through the above steps, the present invention realizes a more accurate and simple transparent corrector design process, which can effectively reduce manual operations and improve the efficiency and quality of corrector manufacturing.

[0031] Effects of the Invention According to the present invention, a program for designing transparent braces using a computer is used to directly print the dental correction device using a 3D printer without making a separate tooth model, which significantly reduces the time and labor required for making the dental correction device, greatly improves the production efficiency of the dental correction device, and thus improves the economy of the product.

[0032] Furthermore, according to the present invention, the program for designing transparent braces using a computer can significantly reduce the cooperation between dentistry and denture factories, and enable dental hospitals to directly manufacture orthodontic devices (in-house manufacturing), thereby simplifying the manufacturing process of orthodontic devices.

[0033] The computer program for designing transparent braces in the present invention sets the movement of teeth (Setup) in each correction stage, so that the tooth arrangement overlaps with the transparent braces to synthesize the treatment image. The user can change the shape of the braces in real time while viewing these images, and immediately confirm the modified treatment image, so that the transparent braces that best match the target teeth can be easily designed.

[0034] According to the present invention, a program for designing transparent braces using a computer is used to improve the comfort and effect of transparent braces made using a 3D printer by providing the shape, thickness and spacing between the teeth and the inner side of the transparent braces at each setting stage to ensure the best correction force.

[0043] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] The advantages and features of the present invention and the methods for achieving these advantages will be described in detail below in conjunction with the embodiments of the accompanying drawings. However, the present invention is not limited to the embodiments described below and can still be implemented in various different forms. These embodiments are only used to ensure the complete disclosure of the present invention and to clearly explain the scope of the invention to those with common technical knowledge in the field. The scope of protection of the present invention is defined only by the claims.

[0045] The present invention relates to a computer program for designing a transparent correction device. Here, the computer includes various devices that perform calculations and provide results to users, specifically including components such as an input processing unit, a calculation unit, and an output unit.

[0046] In this specification, "treatment images" refer to two-dimensional, three-dimensional, or other multi-dimensional images showing the overall arrangement of teeth, including images obtained by medical image processing using tomography. For example, images captured in various formats, including CT (computed tomography) images, nuclear magnetic resonance computed tomography images (NMR (CT)), positron emission tomography images (PET), cone beam CT (CBCT), oral scanners, etc. In addition, "treatment images" include not only the original images captured, but also two-dimensional or three-dimensional images modified by various other reconstruction techniques.

[0047] In this specification, the "target tooth for correction" refers to a tooth whose position is inappropriate or whose rotation is abnormal, and usually requires correction to move its position and / or rotate the tooth.

[0048] In this specification, "lingual side" refers to the side of the tooth that contacts the tongue, "labial side" refers to the side of the tooth that contacts the lips, "buccal side" refers to the side of the tooth that contacts the inner side of the cheek, "occlusal surface" refers to the upper part of the teeth such as molars that is directly used for chewing food, and "cutting surface" refers to the oblique inward surface (the side with the function of cutting food) of the teeth without an occlusal surface (such as incisors, etc.). At the same time, "maximum transverse portion" refers to the part of the tooth with the largest transverse width.

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0050] The S01 stage is the stage for generating and storing the tooth arrangement images set in sequence for each correction stage. Tooth correction is a long process that is carried out through gradual movement, rotation, embedding or protrusion. During the correction period, the teeth are gradually corrected, so the transparent aligners must also be continuously replaced and worn as the correction progresses. In other words, the tooth correction stage is usually completed through dozens of stages, and matching aligners are required at each stage.

[0051] For example, assuming that the dental correction stage is set to 20 stages, the operator sets the correction goal for each stage according to the passage of time, and finally generates 20 stages of tooth arrangement images.

[0052] The 3D scanner scans and stores the patient's dental arrangement image, which is then transmitted to the computer and displayed. In the displayed dental arrangement image, the operator generates a corresponding dental arrangement image according to the correction target of each stage. This process is called "Set-Up" in the present invention. In other words, "Set-Up" means setting the corrected dental arrangement state for each stage.

[0053] Finally, the S01 stage is a stage for generating and storing dozens of tooth arrangement images according to the operator's settings, and the S02 stage is a stage for selecting and displaying any one image from the dozens of stored images.

[0054] The S03 stage is to determine the overall shape of the clear aligner, set the horizontal reference line of each tooth, and display it. The reference line here can be created, connected, extended, disconnected or adjusted according to the shape of the tooth.

[0055] The reference line refers to the setting line of the tooth portion covered by the transparent corrector in the present invention. Depending on the tooth portion where the corrective force is applied, the reference line can be the end of the tooth, the connecting line of the largest transverse portion of the tooth (i.e., the ridge of the tooth), or the boundary line with the gums.

[0056] Figure 6 An embodiment of the transparent corrector of the present invention is shown. Figure 7 Another embodiment is shown.

[0057] For example, for teeth that do not require correction, the end of the tooth can be set as the reference line, or the reference line can be set only partially, so that the transparent aligner is not designed in this part, avoiding unnecessary correction. Figure 6 The figure shows that when the molars on both sides do not need correction, the transparent aligner is omitted in that part; Figure 7 It shows the situation where the braces for the corresponding part are omitted when no correction is required for the entire upper part of the dentition.

[0058] On the other hand, if the peak of the correction target tooth is used as the reference line, different interval values ​​and thickness values ​​can be set for the upper and lower parts according to the reference line to meet the correction requirements of each tooth. In addition, if a reference line is created that separates the correction target tooth left and right, different interval values ​​and thickness values ​​can be set for the left and right parts according to the reference line to meet the correction requirements of each tooth.

[0059] The S04 stage is the stage of forming the cutting line. The cutting line is set on the display to form the edge of the transparent braces. The cutting line is set at a certain distance from the reference line toward the gums, and the distance can be set to different values ​​such as 1mm, 2mm, and 5mm. The position of the cutting line will be determined based on comprehensive factors such as the correction force required for the tooth and the wearing comfort of the transparent braces.

[0060] The S05 stage is a stage for displaying the first treatment image of the transparent braces covering the teeth in the displayed tooth arrangement image.

[0061] Here, the transparent braces are covered on the teeth in a semi-transparent form, and are displayed in the manner of the cut lines set in the S04 stage, covering the upper and lower dentitions. The display mode can be to display the upper and lower dentitions at the same time, or to display them separately.

[0062] The first treatment image shows the state where the clear braces are covered on the teeth (the image of the clear braces is displayed overlapping the image of the teeth), which is a screen at the initial stage of the clear braces design.

[0063] The S06 stage is a stage for inputting the distance value between the teeth and the transparent braces in the first treatment image; the S07 stage is a stage for reflecting the input distance value in the new second treatment image and displaying it.

[0064] The distance between the teeth and the transparent braces directly affects the correction force of the teeth. If the distance is too small (that is, there is almost no gap between the teeth and the braces), the braces cannot be worn smoothly, or may cause severe pain to the patient during the correction process. On the contrary, if the distance is too large (that is, the gap between the teeth and the braces increases), although it is easier to wear, the correction force will be reduced, resulting in poor correction results.

[0065] The S06 stage is to set the overall spacing value between the teeth and the transparent braces based on factors such as the overall wearing feel and correction force of the transparent braces, which is equivalent to the preliminary process of transparent braces design.

[0066] In the S08 stage, the distance between the tooth and the inner side of the transparent brace is corrected to apply the best correction force and direction to the correction target tooth, and a smaller distance value is input. In the S09 stage, the distance value input in the S08 stage is reflected in the new third treatment image and displayed.

[0067] In clear braces, the part that contacts the target teeth needs to have a smaller gap than other parts. This is to make the clear braces fit the target teeth more closely, thus giving the teeth a stronger correction force.

[0068] The spacing value can be input through the menu on the screen. The user can enter the number after clicking the menu button, or open a new window through a pop-up window (pop-up) to enter the number, or directly enter the number by dragging the transparent braces on the screen with the mouse.

[0069] After entering the distance value between the target teeth and the transparent braces, the system will immediately display the third treatment image based on the entered value, and the therapist can visually check whether the distance between each tooth and the transparent braces is set appropriately. If there is an error, the therapist can immediately re-enter the distance value and make real-time corrections.

[0070] The correction of teeth is achieved through their movement, rotation, intrusion and / or extrusion. For example, the target tooth that requires rotational correction needs to be rotated to the target angle by applying torque. In order to apply rotational torque to the target tooth, it is necessary to apply a force that pushes each other left and right on the lingual side and labial side (or buccal side: that is, the inner side close to the cheek) of each tooth. In order to realize this correction force, it is necessary to increase the force that pushes the teeth by reducing the set spacing value (S201) or increasing the set thickness value (S202).

[0071] Therefore, the S201 stage and the S202 stage are mainly aimed at teeth that need rotational correction, by adjusting the spacing value or thickness value in the tooth pushing direction to make it tighter or looser than the original setting value.

[0072] Stages S301 and S302 are stages for designing transparent aligners specifically for teeth that require extrusion correction.

[0073] For target teeth that need to be corrected for protrusion, an extrusion force needs to be applied to the teeth. In order to apply the extrusion force, a smaller spacing value needs to be set in the direction toward the gums based on the baseline of the ridge of the tooth to achieve the target effect.

[0074] In this case, the ridge reference line is used as the dividing point, and the spacing value in the gum direction should be 0.1 to 0.5 mm smaller than the spacing value in the tooth end direction. If the spacing difference exceeds this range, the required protrusive force cannot be obtained; on the other hand, if the spacing difference is less than this value, the comfort of wearing the orthodontic appliance will be greatly reduced.

[0075] The protrusion correction method performed in this way cannot be achieved by the existing sheet pressing method (because the pressing method will cause poor pressing problems at the connection between the teeth and the gums), so it can be regarded as a unique effect of the present invention.

[0076] The S10 stage is a step of inputting the overall thickness value of the transparent aligner. The S11 stage is a step of reflecting the thickness value input in the S10 stage and displaying a new fourth treatment image.

[0077] This is the process of simultaneously inputting and displaying the overall thickness of the clear aligners in order to determine their overall thickness by displaying and visually checking their adequacy in real time.

[0078] The S12 stage is the stage where the thickness value of the part where the clear aligner contacts the correction target tooth is individually modified and input. The S13 stage is the stage where the new fifth treatment image is displayed after the thickness value input in the S12 stage is reflected.

[0079] In order to change the position of the target tooth (or the rotation of the tooth) by applying pressure, the thickness of the clear aligner must reach a certain value. Only when the thickness of the clear aligner reaches a certain value can it exert its required correction effect.

[0080] However, if the thickness of the clear aligner is set too large just to ensure the corrective force, it will significantly reduce the wearing feeling and make the patient feel uncomfortable. In addition, when the thickness exceeds a certain limit, further increasing the thickness will not gain more corrective force.

[0081] The correction method of clear braces is to gradually adjust the position or rotation of the teeth until the target position is reached. When the teeth are gradually corrected and reach the target position, the next stage of clear braces will be replaced, and the next stage of correction will continue with the new braces. Therefore, clear braces need to be gradually replaced according to the set time period.

[0082] Figure 3 The effect of the thickness of the clear aligner on the change in corrective force over time is shown.

[0083] During the general replacement cycle of clear aligners (7 to 14 days), the minimum thickness of the part of the clear aligner that contacts the target teeth is 0.3mm. At this thickness, the correction force can maintain a certain effect; when the thickness reaches 1mm or more, the patient will feel very uncomfortable and it is actually unable to provide more correction force. Therefore, the thickness of the part of the clear aligner that contacts the target teeth should be no less than 0.3mm and no more than 1mm. The more ideal thickness range is 0.3mm to 0.7mm.

[0084] On the other hand, when extraction correction is required, it can be achieved by adjusting the spacing value as explained above. By setting a specified length along the gum direction based on the ridge reference line of the tooth to increase its thickness, an extraction force can also be applied to the target tooth for extraction correction.

[0085] For example, taking the ridge reference line as the dividing point, the thickness is increased by 1 to 2 mm along the gum direction. In this way, a correction force difference will be generated between the upper and lower teeth around the reference line, thereby applying a positive extraction force to the teeth, and the transparent aligner of the present invention will have a positive extraction correction effect.

[0086] The thickness value can also be entered through menu settings, a separate pop-up window, etc., which is the same as the interval value input method, which has been explained before, so the input method will not be explained in detail here.

[0087] The S13 stage is a process of saving the fifth treatment image mentioned above in this stage; in the S14 stage, the saved fifth treatment image and the sixth treatment image saved in the S105 stage will be transmitted to the patient's terminal device. The patient can view the two-dimensional or three-dimensional image of the transparent aligner he is going to wear in advance through his own terminal device (which may require the installation of a specific application in advance).

[0088] The fifth treatment image saved in stage S14 can be a cross-sectional image. Figure 1 Such two-dimensional images can also be three-dimensional images. These images will be transmitted through 3D printers and other equipment for the production of transparent aligners.

[0089] On the other hand, some patients may have conditions such as severe malocclusion, in which case additional correction may be required in addition to the correction ensured by the spacing value and thickness setting.

[0090] At stage S101, the patient can choose whether to attach button-type add-ons to the inner side of the clear aligners.

[0091] like Figure 4 As shown, the button-type attachment is in a protruding shape and is formed on the inner side of the transparent aligner so as to apply a stronger correction force to the teeth of the correction object, thereby achieving more effective correction. In addition to the usual correction force, when an additional correction force is required, by selecting the button-type attachment, a transparent aligner with a stronger correction force can be designed.

[0092] Figure 4 Attachments are installed on the clear aligner in order to apply a rotational torque to guide the rotational correction of the teeth. The attachments are installed on the inner side of the clear aligner and are installed at positions relative to each other to apply the rotational torque. The positions of these attachments can be designed in various ways according to the environment of the target teeth to be corrected. Figure 4 This is only one embodiment of the present invention.

[0093] Step S102 is a step of selecting whether to add hook-shaped attachments to the outer side of the transparent aligner.

[0094] When additional correction is required beyond the normal correction, such as Figure 5As shown, a hook-shaped attachment attached to the outer side of the transparent corrector can be used. Unlike the aforementioned button-type attachment, the hook-shaped attachment is formed on the outer side of the transparent corrector. Of course, depending on the situation, these two attachments can also be used at the same time.

[0095] Step S103 is a step of setting the shape, size and attachment position of the button-type attachment and the hook-shaped attachment selected in steps S101 and S102, and step S104 is a step of displaying the sixth treatment image after the final modification.

[0096] For example, the shape of the button-type attachment can be circular, square, diamond, etc., and its size (cross-sectional area) can also be changed according to the environment of the target teeth to be corrected. These examples of changes all fall within the technical scope of the present invention.

[0097] Step S103 is a process of determining the size (extent of protrusion, surface area, etc.) and position of a button-type appendage and / or a hook-type appendage when it is decided to use it. After completing this process, the sixth treatment image will be completed and saved.

[0098] As described above, it is obvious that the types and shapes of button-type attachments and hook-shaped attachments can be varied. It is also entirely feasible to create a separate folder to list button-type attachments and hook-shaped attachments of various shapes and sizes, and open the folder when necessary to design by overlaying the display on the screen.

[0099] Therefore, these modified examples are only simple changes of the present invention, do not deviate from the technical essence of the present invention, and obviously belong to the scope of rights of the present invention.

[0100] The program according to the invention may be a computer program (also referred to as program, software, software application or code) comprising machine instructions for a programmable processor and may be implemented using high-level procedural and / or object-oriented programming languages, and / or assembly / machine languages.

[0101] Each step described in this application can be performed in parallel, can also be performed sequentially, or can be performed in other orders, provided that the desired result of the technical solution proposed in this application is achieved. Therefore, as long as the predetermined target result can be achieved, no particular limitation is made. The above specific implementation methods do not limit the protection scope of this application. Those of ordinary skill in the art can make various modifications, combinations, sub-combinations and substitutions according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the scope of the ideas and principles of this application belong to the protection scope of this application.
