[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] According to one embodiment of the present invention Orthodontic wire former The method for forming an orthodontic wire is carried out according to the flowchart shown in FIG.

[0016] First, in step ST1, as shown in FIG. 2, the patient P's oral cavity is scanned with a 3D scanner 2 while looking at a touch panel 1, and as shown in FIG. 3, dental impression data 3, which is 3D data of the dental impression, is collected and imported into a computer (not shown), and then the process proceeds to step ST2.

[0017] In step ST2, the collected 3D data is processed in a computer by operating the touch panel 1, and the 3D data is corrected to achieve the target tooth alignment after orthodontic treatment, as shown in Figure 4, to create original dental impression model data (corrected dental impression model data) 6, and then the process proceeds to step ST3.

[0018] In step ST3, an original dental impression model 8 is produced using a 3D printer 7 as shown in FIG. 5 based on the original dental impression model data 6, which is the corrected 3D data, and the process proceeds to step ST4.

[0019] In step ST4, as shown in Figure 6, the multiple model teeth 9 of the original dental impression model 8 are individually divided, and as shown in Figure 7, a set-up dental impression model 11 is created in which each model tooth 9 is arranged in a pseudo-gingiva 10, and then the process proceeds to step ST5.

[0020] In step ST5, as shown in FIG. 8, a wire material 5 for use in orthodontics is laid over the set-up dental impression model 11 and bent to fit the set-up dental impression model 11 to form an orthodontic wire 12, and then the process proceeds to step ST6.

[0021] Orthodontic brackets 41 for attaching the orthodontic wire 12 to the patient's teeth are attached to this wire material 5 (orthodontic wire 12), and the positioning of these orthodontic brackets 41 is also performed.

[0022] The orthodontic wire 12 is formed using an orthodontic wire forming tool 13, which will be described later.

[0023] In step ST6, as shown in FIG. 9, the arrangement of the model teeth 9 of the set-up dental impression model 11 is finely adjusted.

[0024] That is, minute adjustments are made to the wire material 5 (or the orthodontic wire 12) or the orthodontic bracket 41 and the tooth model 9 at points where they are separated or in contact with each other.

[0025] In step ST7, as shown in FIG. 10, each model tooth 9 of the set-up dental impression model 11 is used to fabricate a core 42 for bonding the orthodontic bracket 4 to the tooth T of the patient P.

[0026] That is, core resin is supplied between the orthodontic bracket 41 and each model tooth 9 of the set-up dental model 11, or from the inside to the top of each model tooth 9, and then solidified to produce a core 42 as shown in Figures 11 and 12.

[0027] In step ST8, as shown in FIG. 13, the support base 15 is removed from the base 23, and further, as shown in FIG. 14, the core 42 together with the orthodontic bracket 41 is removed from the orthodontic wire 12.

[0028] In step ST9, as shown in FIGS. 15 and 16, the core 42 is attached to the tooth T of the patient P together with the orthodontic bracket 41.

[0029] In step ST10, as shown in FIG. 17, the excess portion of the core 42 is removed.

[0032] The support base 15 has a pair of V-shaped guide grooves 16 that extend along the front-rear direction inside the set-up dental impression cast 11 .

[0033] The stand 14 includes a front stand member 17 erected at the front of the support base 15 and a pair of side stand members 18 erected at the sides of the support base 15 .

[0034] The front stand member 17 also has a front standing portion 19 whose lower part is fixed to the support base 15, and a front extension portion 20 which extends forward from the upper part of the front standing portion 19, whose tip engages with the recess between adjacent front teeth and on which the wire material 5 is placed.

[0035] The side stand member 18 has a side standing portion 21 whose lower part is slidably guided in the guide groove 16 of the support base 15, and a side extension portion 22 which extends outward from the upper part of this side standing portion 21, whose tip engages with the recess between adjacent molars and on which the wire material 5 is placed.

[0036] The wire material 5 is bent to fit the template, and an orthodontic bracket 41 is attached to the wire material 5.

[0037] Then, the wire material 5 is adjusted so that the set-up dental impression 11 and the wire material 5 fit to some extent.

[0038] The wire material 5 is fixed to the front extension 20 of the front stand member 17 and the side extension 22 of the side stand member 18 by adhesive or the like.

[0039] Furthermore, the orthodontic wire forming tool 13 has a base 23 for fixing the artificial gums 10 of the set-up dental model 11 as shown in FIG. 7, and for supporting the support base 15 inside the set-up dental model 11 as shown in FIG. 8.

[0042] That is, the dental impression plate 27 has a front tooth plate 28 and a pair of back tooth plates 29, and the front tooth plate 28 has dental impressions of the tip portions of the front teeth of the original dental impression model 8 formed thereon, and the back tooth plate 29 has dental impressions of the tip portions of the back teeth of the original dental impression model 8 formed thereon.

[0043] Furthermore, the tray 26 has a fitting portion 30 into which the dental impression plate 27 is removably fitted, and this fitting portion 30 is configured to have a front tooth recess 31 into which the front tooth plate 28 is removably fitted, and a pair of back tooth recesses 32 into which the back tooth plate 29 is removably fitted.

[0044] As shown in FIGS. 23 and 24, the original dental impression model 8 can be positioned.

[0045] Furthermore, as shown in FIG. 25, the orthodontic wire forming tool 13 is provided with a spacer 33 which is placed inside the original dental impression model 8 when taking a dental impression of the original dental impression model 8, and which is placed between the base 23 and the tray 26 when creating the setup dental impression model 11.

[0046] The spacer 33 has a notch 34 formed therein, and the tray 26 has a protrusion 35 formed therein to fit into the notch 34 .

[0047] A spacer 33 is also fitted into the fitting recess 24 of the base 23 .

[0048] This allows the base 23, tray 26 and spacer 33 to be aligned.

[0049] When taking a dental impression of the original dental model 8 using the orthodontic wire forming tool 13 configured in this manner, first, as shown in Figure 26, the front tooth plate 28, the back tooth plate 29, and the spacer 33 are set in the tray 26, and putty silicone 37 is applied to the peripheral portion of the tray 26.

[0050] Next, as shown in FIG. 27, the original dental impression model 8 is pressed against the putty silicone 37, and as shown in FIG. 28, the dental impression of the original dental impression model 8 is imprinted on the putty silicone 37.

[0051] Next, as shown in FIG. 29, the peripheral edge of the putty silicone 37 is left and the portion with the tooth impression is removed.

[0052] Next, as shown in FIG. 30, a silicone impression material 38 is piled up inside the silicone putty 37.

[0053] Next, as shown in FIG. 31, the original dental impression model 8 is pressed against the silicone impression material 38, and as shown in FIG. 32, the dental impression of the original dental impression model 8 is imprinted on the silicone impression material 38.

[0054] Next, the tooth model 9 obtained by dividing the original dental impression model 8 shown in FIG. 6 is fitted into the dental impression of the silicone impression material 38 as shown in FIG.

[0055] Next, as shown in FIG. 25, wax 39 is poured to press the base 23 and the tray 26 together, and the wax 39 is cooled until it hardens.

[0056] Next, the tray 26, the putty silicone 37, and the silicone impression material 38 are removed, and the set-up dental impression model 11 is produced as shown in FIG.

[0057] According to the above configuration, the patient's dental impression is collected as 3D data using the 3D scanner 2, and this 3D data is then modified to achieve the desired tooth alignment after orthodontic treatment to create original dental impression data 6. An original dental impression model 8 is then produced using the 3D printer 7 based on this original dental impression model data 6. This allows the setup dental impression model 11 to be easily produced without requiring any skill.

[0058] In addition, the arrangement of each model tooth 9 in the set-up dental impression model 11 can be finely adjusted, that is, fine adjustments can be made to the locations where the wire material 5 and the model tooth 9 are separated or come into contact with each other, so that it is possible to correct small imbalances in the teeth that cannot be noticed when creating a digital set-up dental impression model 11 using a 3D scanner 2 or 3D printer 7.
