Description

  The present invention relates to an instrument used in orthodontic treatment, and more particularly, to a jig used to attach an orthodontic bracket to a crown.

  Conventionally, there is a method of correcting a dentition by attaching a bracket to the palatal side or the lingual side of a crown and ligating a wire to the bracket. By attaching the bracket to the palate side or the lingual side of the crown, the bracket and the wire become inconspicuous. In recent years, orthodontic treatment from the back side of teeth has been actively performed.

  FIG. 8 is a diagram illustrating a state where the brackets 10 and 11 are attached to the palate side or the lingual side of the crown portion 7. In FIG. 8, the unoccluded state is eliminated. FIG. 9 is a perspective view of the bracket 10. FIG. 10 is a perspective view of the bracket 11. The brackets 10 and 11 shown in FIGS. 9 and 10 are merely examples. As shown in FIG. 8, orthodontic treatment is performed by attaching the brackets 10 and 11 to the palate side or the lingual side of the crown portion 7 and ligating the wires to the brackets 10 and 11. The mounting position of the brackets 10 and 11 must be accurate. Therefore, as described in Non-Patent Document 1, a jig called a hybrid core has been developed.

  11 and 12 are diagrams showing a process for manufacturing the conventional jig 12c. 11 and 12, a DD cross section in FIG. 8 is shown. FIG. 13 is a perspective view showing the completed jig 12c. FIG. 14 is a perspective view showing a state when the bracket 5 is attached to the jig 12c. Hereinafter, a conventional method for manufacturing the jig 12c will be described with reference to FIGS.

  First, the teeth to be corrected on the oral model are divided one by one, and a setup model 9 arranged in a desired dentition form and occlusal state is prepared. Next, as shown in FIG. 11, the melted wax 8 is poured into and fixed to the surface of the crown portion 7 formed on the setup model 9 on the palate side or the lingual side. Next, as shown in FIG. 12, the plasticized resin 12 is deposited so as to cover a part of the end portion of the crown portion 7 and the upper surface 5 a of the bracket 5. Thereafter, the resin 12 is cured. After the resin 12 is cured, the wax 8 is melted, and the resin 12 and the bracket 5 are removed from the crown portion 7. With respect to the removed resin 12, excess resin on the surface is polished, and as shown in FIG. 13, a jig 12c having a flat surface is obtained. The jig 12c is used to determine the mounting position of the bracket 5.

  As shown in FIG. 13, the jig 12c has a recess 12a. Since the recess 12a is formed so as to cover a part of the end of the crown part 7, it has a shape along a part of the end. Moreover, as shown in FIG. 13, the jig | tool 12c has the recessed part 5b. Since the recess 5b is formed so as to cover the upper surface 5a of the bracket 5, it has a shape along the upper surface 5a.

  As shown in FIG. 14, the bracket 5 is fitted into the recess 5 b, and the resin 12 and the bracket 5 are fixed by the rubber band 13. In this way, the jig 12c is manufactured for each of the crown portions 7 to which the bracket 5 is attached.

  The recess 12a of the resin 12 fits the crown portion 7 exactly. Therefore, the bracket 5 attached to the jig 12c is positioned at an appropriate place.

  When performing orthodontic treatment, the dentist applies an adhesive to the bottom surface of the bracket 5 attached to the jig 12c as shown in FIG. 14, and the concave portion 12a of the jig 12c is applied to the corresponding patient's crown. Fit and cure the adhesive. Thereafter, the dentist removes the rubber band 13 and removes the jig 12 c from the bracket 5. In this manner, the bracket 5 is adhered to an appropriate position on the patient's crown, and orthodontic treatment from the palate side and the lingual side (back side) is realized. Even if the bracket 5 may come off during the treatment, the bracket 5 may be attached to the jig 12c with a rubber band and the bracket 5 may be adhered to the patient's crown.

  FIG. 15 is a plan view showing a state when the jig 12 c is placed on the setup model 9. As shown in FIGS. 13 and 14, the conventional jig 12c had to have a certain thickness and width in order to have strength. Therefore, as shown in FIG. 15, the jigs 12 c are arranged at a considerably narrow interval even when the crown portion is arranged at an appropriate position as in the setup model 9. Therefore, when the jig 12c is set on the crown of the patient who is not occluded, the jig 12c hits the adjacent crown, and the jig 12c cannot be set as desired. There arises a problem that 5 cannot be accurately adhered to an appropriate position.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bracket mounting jig that is not obstructive when set on a dental crown of a patient.

  In order to solve the above problems, the present invention has the following features. The present invention is a bracket mounting jig for determining the mounting position of a bracket when mounting a bracket for correction on each tooth of a patient, and has a shape along a part of the end of the crown portion. A first resin portion including a recess, a second resin portion including a recess formed along at least a portion of the upper surface of the bracket attached to the crown portion, and one end portion attached to the first resin portion. And a rigid member having the other end attached to the second resin portion.

  Preferably, the rigid member has a plurality of perforations. Preferably, the rigid member has a rib portion protruding from the first resin portion to the second resin portion. Preferably, the upper side portion of the rib portion has irregularities. Preferably, the rigid member is bent.

  To manufacture a bracket mounting jig for determining the bracket mounting position when mounting orthodontic brackets on each tooth of a patient, a process of placing resin on a part of the end of the crown of the setup model And a step of depositing resin on a part of the upper surface of the bracket temporarily fixed to the crown portion, and a step of attaching a rigid member to the two accumulated resins.

  The bracket mounting jig of the present invention may be used when orthodontic treatment is performed by attaching a bracket to the back side of the crown (the lingual and palatal sides of the crown), or the front side of the crown. You may use when attaching a bracket to (the lip side surface and cheek side surface of a crown part), and performing orthodontic treatment.

  According to the present invention, since the strength of the entire jig is reinforced by using the rigid member, the amount of resin to be used can be reduced as compared with the prior art. Therefore, the whole jig is reduced in size, and it becomes difficult to get in the way when setting the jig on the patient's crown.

  Further, by providing a plurality of perforations in the rigid member, it is possible to easily fix the resin and the rigid member. If the rib portion is provided on the rigid member, the strength of the entire jig is further increased. Further, if the upper side portion of the rib portion is provided with irregularities, the rubber band for attaching the bracket to the jig can be easily hooked, and convenience is improved. If the rigid member is bent, the joint area between the rigid member and the resin can be increased, and the strength of the entire jig is further increased.

  Manufacturing the jig of the present invention is simple and easy to provide the jig of the present invention. As a result, the cost of the jig and the treatment cost of orthodontic treatment are reduced.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

  FIG. 1 is a perspective view showing a bracket 1 for attaching a bracket according to a first embodiment of the present invention. The jig 1 includes a first resin part 4, a second resin part 3, a metal part 2, a bracket 5, and a rubber band 6. FIG. 2A is a front view of the metal part 2. FIG. 2B is a right side view of the metal part 2. The metal part 2 is a plate-like member in which the width on the first resin 4 side is wider than the width on the second resin 3 side. The metal part 2 includes a plurality of perforations 2a. As shown in FIG. 2A, the plurality of perforations 2 a may be provided not only on the body portion of the metal portion 2 but also on the periphery. As shown in FIG. 1, in the metal part 2, one end part having a wider width is attached to the first resin part 4. Further, in the metal part 2, the other end part having the narrower width is attached to the second resin part 3. The metal part 2 is bent toward the palate side or the lingual side from the upper end part of the crown part. The bending angle of the metal part 2 is preferably 90 degrees or more, but is not particularly limited. Note that the metal portion 2 may be embedded in the first resin portion 4 at one end portion, or a part thereof may be exposed from the first resin portion 4. Similarly, at the other end portion, the metal part 2 may be embedded in the second resin part 3 or a part thereof may be exposed from the second resin part 3.

  3-5 is a figure which shows the process for manufacturing the jig | tool 1. FIG. 3-5, the AA cross section in FIG. 6 is shown. Hereinafter, the manufacturing method of the jig 1 will be described with reference to FIGS.

  First, the teeth to be corrected on the oral model are divided one by one, and a setup model 9 arranged in a desired dentition form and occlusal state is prepared. Next, as shown in FIG. 3, the brazed 5 is poured into the palate side or the lingual side surface of the crown portion 7 formed in the setup model 9 to fix the bracket 5. Next, as shown in FIG. 3, plasticized resin 4 a is deposited so as to cover a part of the end of the crown portion 7. Furthermore, the plasticized resin 3a is stacked so as to cover at least a part of the upper surface 5a of the bracket 5.

  Before the resins 4a and 3a are cured, the metal part 2 is attached to the resins 4a and 3a as shown in FIG. In the metal part 2, the wide side is pressed against the resin 4a, and the narrow side is pressed against the resin 3a. At this time, since a plurality of perforations 2a are formed in the metal portion 2, the resins 4a and 3a enter the perforations 2a, and the resins 4a and 3a protrude from at least a part of the perforations 2a. .

  Next, as shown in FIG. 5, the resin 4b is further deposited on the resin 4a side. Thereafter, the resins 4a, 4b and 3a are cured. After the curing, the first resin portion 4 is formed, and one end portion of the metal portion 2 is attached to the first resin portion 4. In addition, the resin 3 a becomes the second resin portion 3, and the other end portion of the metal portion 2 is attached to the second resin portion 3. In FIG. 5, the second resin portion 3 may be formed by further stacking resin on the resin 3 a side. Since the strength is enhanced by the metal part 2, the amount of resin necessary for forming the first resin part 4 and the second resin part 3 may be a minimum amount.

  After curing, the wax 8 is melted and the first resin part 4, the second resin part 3, the metal part 2, and the bracket 5 are removed from the crown part 7. Thereafter, if necessary, excess resin of the first resin portion 4 and / or the second resin portion 3 is polished. Finally, the bracket 5 is attached to the second resin portion 3 with a rubber band 6 to complete the jig 1 as shown in FIG.

  As shown in FIG. 5, the 1st resin part 4 has the recessed part 4c. Since the concave portion 4c is formed so as to cover a part of the end portion of the crown portion 7, the concave portion 4c has a shape along a part of the end portion. Furthermore, as shown in FIG. 5, the second resin portion 3 has a recess 3b. Since the recess 3b is formed so as to cover at least a part of the upper surface 5a of the bracket, the recess 3b has a shape along at least a part of the upper surface 5a.

  The concave portion 4 c of the first resin portion 4 fits the crown portion 7 exactly. Therefore, the bracket 5 attached to the jig 1 is located at an appropriate place.

  When the orthodontic treatment is performed, the dentist applies an adhesive to the bottom surface of the bracket 5 attached to the jig 1 as shown in FIG. 1, and the concave portion 4c of the jig 1 is applied to the corresponding crown of the patient. Fit and cure the adhesive. Thereafter, the dentist removes the rubber band 6 and removes the jig 1 from the bracket 5. In this way, the bracket 5 is bonded to an appropriate position on the crown portion of the patient, and the orthodontic treatment from the back side is realized. Even if the bracket 5 may come off during the treatment, the bracket 5 may be attached to the jig 1 with a rubber band again, and the bracket 5 may be adhered to the patient's crown.

  FIG. 6 is a plan view showing a state when the jig 1 is placed on the setup model 9. As shown in FIG. 6, when the jig 1 is placed on the setup model 9 arranged at a normal position, the jig 1 is in contact with the adjacent crown or jig 1 as compared with the conventional FIG. It has become difficult. Since the jig 1 according to the present embodiment uses the metal part 2 to strengthen the jig 1, the amount of resin can be minimized. Therefore, the jig 1 is downsized compared to the conventional one. Therefore, when the jig 1 is set on the crown portion of the patient who is not occluded, the jig 1 hits the adjacent crown portion, and the jig 1 cannot be set as desired. As a result, the bracket 1 It is possible to solve the problem that the film cannot be accurately bonded to an appropriate position. Therefore, the bracket mounting jig 1 is provided which is not obstructive when set on the dental crown of the patient.

  The amount of resin in the first resin portion 4 and the amount of resin in the second resin portion 3 are not particularly limited. In order to reduce the size of the jig 1 as much as possible, the amount of resin in the first resin portion 4 and the second resin portion 3 should be minimal, but the strength is insufficient, the fixing force of the metal portion 2, The manufacturer may determine as appropriate in consideration of the type and size of the tooth to be attached, the non-occlusion state, and the like.

  In the present embodiment, the first resin portion 4 and the second resin portion 3 are separated from each other. However, a part of the first resin portion 4 and the second resin portion 3 is connected. You may do it. When the resin 4a or 3a is deposited at the stage of manufacturing the jig 1, the resin 4a and the resin 3a may be partially connected to manufacture the jig 1. In the conventional jig, the resin 12 has to have a size and thickness that can obtain strength. However, in this embodiment, since the strength is obtained using the metal part 2, the situation where a part of the resin 4a and the resin 3a are connected is not intended to obtain strength. Absent. By connecting a part of the resin 4a and the resin 3a, it is possible to prevent the jig 1 from being manufactured easily or when the metal part 2 comes into contact with the crown part and the patient feels uncomfortable. I can do it.

  In addition, the shape of the metal part 2 is not specifically limited. The metal part 2 may be a rectangular plate member, a lattice member, a columnar member, or a wire member.

  7A to 7D are diagrams illustrating examples of other shapes of the metal part 2. 7A is a front view, FIG. 7B is a right side view, FIG. 7C is a BB sectional view, and FIG. 7D is a CC sectional view. Thus, the metal part 2 may have the rib part 2c which protruded from the 1st resin part 4 to the 2nd resin part 3. FIG. As shown in FIG. 7B, the rib portion 2c has an uneven portion 2d on the upper side. By providing the rib portion 2c, the strength of the metal portion 2 is further strengthened. Moreover, the rubber band 6 is easily hooked by providing the unevenness 2d on the upper side portion of the rib portion 2c.

  Moreover, since the metal part 2 can connect the 1st resin part 4 and the 2nd resin part 3 even if it is not bent toward the palate side or the tongue side from the upper end part of a crown part. If it exists, it may be linear. However, when the metal part 2 is curved from the upper end part of the crown part to the palate side or the lingual side, the bonding area between the first resin part 4 and the metal part 2 increases, so that the strength increases. In addition, in the metal part 2, the shape and angle of bending are not particularly limited.

  Furthermore, the metal part 2 may be replaced with a molded resin member. That is, the member that connects the first resin portion 4 and the second resin portion 3 may be a rigid member that has a property that is difficult to be deformed by an external force such as bending or twisting.

  In the present embodiment, the metal part 2 has a plurality of perforations 2a, but the perforations 2a may not be provided. Since the metal part 2 and the first and second resin parts 4 and 3 are joined if a surface treatment that can be joined to the resin is performed on the metal part 2, the perforation 2a is an essential component of the present invention. It is not an element. Moreover, unevenness | corrugation may be formed in the surface of a metal part, and a metal part and resin may be joined. In addition, the metal part and the resin may be joined by applying a chemical to the surface of the metal part, heat-treating the surface, or cleaning the surface.

  In this embodiment, the wax 8 is used to temporarily fix the bracket 5. However, the present invention is not limited to this, and the bracket 5 is formed by using an appropriate temporary fixing material such as silicon. It only has to be temporarily fixed to the crown.

  In the present embodiment, the jig for attaching the bracket to the palate side surface or the lingual side surface, which is the back side of the crown portion, has been described. It can also be used to attach a bracket to the side. When the bracket is attached to the front side of the crown portion, the jig of the present invention is similar to the above embodiment in that the first resin portion including a recess having a shape along a part of the end portion of the crown portion, and the tooth A second resin portion including a concave portion shaped along at least a part of the upper surface of the bracket attached to the front side (lip side surface and cheek side surface) of the crown portion, and one end portion is attached to the first resin portion; And the other end part is provided with the rigid member attached to the 2nd resin part. Similar to the above embodiment, the rigid member may have a plurality of perforations, may have a rib portion having irregularities on the upper side portion, or may be bent. The manufacturing method of the jig is the same as that of the above embodiment, and the step of placing resin on a part of the end portion of the crown portion of the setup model and the upper surface of the bracket temporarily fixed on the front side of the crown portion. A step of depositing resin on the part and a step of attaching a rigid member to the two accumulated resins.

  As mentioned above, although this invention was demonstrated in detail, the above-mentioned description is only the illustration of this invention in all the points, and does not intend to limit the range. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The bracket mounting jig according to the present invention can be used in the field of dental instruments and the like.
