Description

  The present invention relates to an orthodontic apparatus that can be easily mounted and replaced on a dentition and can impart a reliable correction force to the dentition.

  Orthodontic appliances fix attachments such as brackets and tubes directly to the tooth surface or via bands attached to the teeth, and sequentially hold metal main wires (hereinafter referred to as wires) to each attachment. The device corrects the dentition to a desired arrangement by applying an orthodontic force to each tooth using the tension of the wire.

  The combination of the wire and the attachment applies a predetermined force to the teeth so that each tooth is changed and moved to a desired state, for example, the teeth are pulled forward or rotated. Since the force applied to the teeth varies from tooth to tooth depending on the state of the teeth in this way, many types of attachments are prepared in advance, and the most suitable one for each tooth is selected and placed at a predetermined position on the tooth. The attachment was glued at a predetermined angle so that the desired force was applied to the teeth. (For example, refer to Patent Document 1).

Japanese Patent Application Laid-Open No. 11-206784.

  However, conventionally, since a strong adhesive was applied or the attachment was fixed using electric welding, it was not easy to remove the fixed attachment from a tooth or a band. For this reason, it has been necessary to carefully perform bonding and welding operations by adjusting the position and angle so that the attachment is not bonded again.

  Further, since the teeth move as the orthodontic treatment proceeds, it is necessary to change the initially set orthodontic force. Even in such a case, since it is impossible to change the type of attachment that has already been bonded, or to change its attachment position or angle, the wire is bent in a complicated manner, and the moved tooth has a force in the desired direction. To be added.

  Further, for example, even after the treatment has progressed, it is not necessary to apply the correction force, and the attachment that was initially bonded cannot be easily removed, and the attachment that has already become unnecessary must be used as it is.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an orthodontic apparatus that can be easily mounted and replaced on a dentition and can easily cope with changes in the dentition that occur during correction.

Since the grip part can be selected and attached arbitrarily, and the grip part can be easily changed during orthodontic treatment, the best grip part at the time of attachment is always selected without considering changes in the dentition due to correction. Can be used. Further, by replacing the gripping portion, it is not necessary to bend the wire in a complicated manner, and the wire can be stretched linearly.

  Even if the gripping part is damaged or deformed during correction, it can be easily replaced with a new gripping part if the base is properly bonded.

  By attaching and attaching a scale plate for positioning to the base, positioning of the base becomes easy and reliable, and the bonding work is simplified.

  The base can be easily removed by attaching and removing a jig for removal from the base.

  The retainer can be fixed to the base part from which the gripping part has been removed, so that the retainer can be securely attached, and the orthodontic dentition can be reliably held with a retainer having a simple configuration.

  One embodiment of an orthodontic apparatus according to the present invention will be described with reference to the drawings.

  As shown in FIG. 9, the orthodontic appliance 2 (hereinafter referred to as an orthodontic appliance 2) includes an attachment 4 and a metal main wire 6 (hereinafter referred to as a wire 6) as main components, and other bands 8. (Refer to FIG. 10), and a knotted rubber that fixes the wire 6 to the attachment 4.

  As shown in FIGS. 1 and 2, the attachment 4 includes a base 3 bonded to the surface of the tooth 1 and a grip 5 attached to the base 3.

  The base 3 is made of metal, ceramic, or the like, and a connector 9 is formed on the surface of a slightly curved plate-like base 7. As shown in FIG. 3, the connector 9 has a trapezoidal cross section with the base 7 side narrowed, and a locking portion 11 that is widened to the left and right is formed at one end in the longitudinal direction, and a fitting portion 13 is further provided. It has been.

The gripping part 5 is formed with a gripping tool 15 for gripping the wire 6 on the front side, and a fitting groove 17 formed of a trapezoidal concave part connected to the connection tool 9 on the back surface and a fitting part 13 to be fitted. A joint hole 19 is provided. As shown in FIG. 4, the base 3 may not be provided on the base 3, and the base 3 having only the connector 9 may be bonded directly to the teeth 1 without the base 7 . Further, the shape of the connecting groove 17 is not trapezoidal, but may be rectangular as shown in FIG. 5, and the fitting portion 13 may be provided on the connecting groove 17 side.

  Furthermore, the gripping tool 15 is not limited to that shown in the figure, and any kind of conventionally used tools can be used. Further, instead of the wire 6, rubber or resin material or the like may be used to impart orthodontic force to the teeth 1. In this way, a number of gripping portions 5 such as the connecting grooves 17 that are connected to the base 3 on the same side and have different gripping tools 15 are prepared in advance.

  Next, the procedure for mounting the orthodontic appliance 2 on the dentition will be described.

  First, an adhesive is applied to the back surface (adhesion surface) of the base 7, and the base 3 is fitted into the connecting groove 17 of the positioning scale plate 35 shown in FIG. 12. The positioning scale plate 35 is provided with a reference line 36 serving as a reference such as the upper end, the lower end, or the side end of the tooth 1. When the reference line 36 is aligned with the tooth 1, a standard position, for example, the tooth 1 is formed. It is comprised so that the base 3 may be attached to the center part.

  The scale plate 35 may be formed so that the base 3 is arranged not only at a standard position but also at another desired position of the tooth 1.

  When the base 3 is bonded to the tooth 1, the scale plate 35 is removed from the bonded base 3. Similarly, a new base 3 is bonded to the tooth 1.

  As shown in FIGS. 6 and 7, if the base 3 is bonded to each tooth 1 of the dentition, the gripping part 5 is selected in consideration of the type and strength of the correction force applied to the tooth 1, and each base Attach to 3. Since the connecting groove 17 is formed on the back surface of the gripping portion 5, the gripping portion 5 can be easily attached by simply connecting the connecting groove 17 to the connecting tool 9 as shown in FIGS. Further, the fitting piece 19 is fitted into the fitting portion 13, and the grip portion 5 is securely fixed to the base portion 3.

  In addition, you may fix the base 3 to the band 8 wound around the tooth | gear 1 which is a molar as shown in FIG. In this case, in addition to fixing the base 3 to the band 8 using brazing, welding, or the like, the base 3 may be formed by bonding the base 3 to the band 8 with an adhesive or processing the band 8 itself. When the band 8 is used, for example, the tube 23 provided with the connecting groove 17 is fixed to the band 8, and the left and right ends of the wire 6 are fixed to the tube 23.

  As shown in FIGS. 8 and 9, when the gripping portions 5 are attached to all the base portions 3, the wires 6 are attached to the gripping portions 5. Since each gripping part 5 is provided with a gripping tool 15 corresponding to correction, a predetermined correction force is generated by gripping the gripping tool 15 with rubber or the like that ties the wire 6.

  As described above, the attachment 4 is composed of the base 3 that directly adheres to the tooth 1 and the grip 5 that is detachably attached to the base 3, so that the type and size of the correction force required for each tooth can be adjusted. Regardless, the base 3 can be bonded to the tooth 1 under substantially the same conditions. In addition, since the grip portion 5 can be arbitrarily selected from a large number of types, the orthodontic apparatus 2 most suitable for the correction of the dentition can be configured.

  Further, when the type or size of the correction force on the tooth 1 changes as the treatment progresses, and it becomes difficult to handle the gripping part 5 already attached to the tooth 1, the gripping part from the base part 3 is used. 5 is removed, and a new gripping portion 5 is selected to attach the wire 6 to the base 3. As a result, the optimal correction force can always be applied to the tooth 1, and excessive bending of the wire 6 to match the incompatible attachment is eliminated.

  Further, when the grip portion 5 is damaged, the damaged grip portion 5 is removed from the base portion 3 and a new grip portion 5 is attached to the base portion 3. Further, when the correction device 2 is soiled, the correction device 2 is removed from the base 3 with the wire 6 attached, and after the cleaning of the correction device 2 and the teeth, the grip 5 is attached to the base 3 and the correction device. 2 can be mounted again.

  The base 3 and the grip 5 may be made of metal or ceramic, and both materials are not limited. Alternatively, a ceramic gripping portion 5 may be attached to the metal base 3 or vice versa.

  Another example of the orthodontic appliance will be described. In this example, a correction tool made of resin is used. The orthodontic tool processes, for example, a tooth shape collected from the dentition of a patient to be corrected, and forms a tooth profile having a desired dentition after correction. Then, an orthodontic appliance having a desired dentition is prepared from the tooth mold using a resin.

  Further, the base 3 is fixed to each tooth 1 in the same manner as described above, and an engaging portion such as a protrusion is attached to the base 3. The orthodontic appliance is provided with a recess that fits into the engaging portion so that when the engaging portion and the recess are fitted, the dentition of the orthodontic appliance forms a corrected dentition.

  And an engaging part is attached to the base 3, and a corrector is mounted | worn, combining a recessed part with this engaging part. Then, the correction force is applied from the correction tool to the tooth that is displaced from the desired dentition, and the tooth in the displaced state is corrected to the desired state. Moreover, you may perform correction | amendment by this correction tool using the same base 3, after correcting by the correction apparatus using a wire. The reverse order may also be used.

Further, a retainer that holds the dentition may be held on the base 3 so that the corrected tooth 1 does not return to the state before correction. The retainer is formed with a metal wire or resin so as to match the dentition after correction. If it does in this way, a dentition retention apparatus can be easily comprised using this invention.

  For example, after the correction of the dentition by the correction device is completed, all the grips 5 are removed from the base 3 and the retainer is fixed to the base 3 left on the teeth 1. Then, the retainer is fixed by the base 3, and the corrected tooth 1 can be reliably held without any deviation.

  In addition, the retainer is not directly attached to the base 3, but the grip portion 5 formed with a protrusion or an engagement portion is attached to the base 3, and a recess or the like that matches the shape of the grip portion 5 is formed on the retainer. You may make it mount a retainer via.

  Further, a removing device 30 for removing the base 3 from the tooth 1 may be configured as shown in FIG. For example, the connecting groove 17 that fits the connecting tool 6 is provided at the tip of the handle portion 31, the handle portion 31 of the removing device 30 attached to the base portion 3 is gripped by hand, and a force is applied to the removing device 30. Then, the base 3 can be easily detached from the tooth 1 when the orthodontic treatment of the dentition is completed or when it is reattached.

  In the above example, the connecting tool 9 is provided on the base 3. However, in the present invention, the connecting tool 9 and the connecting groove 17 are not limited thereto. For example, as shown in FIG. 13, the base 3 is provided with a connecting groove 17 having a trapezoidal cross section, the connecting part 9 having a trapezoidal cross section is provided in the operating part 5, and the operating part 5 is attached to the base 3 fixed to the tooth 1. May be. Furthermore, the cross-sectional shape of the connecting groove 17 or the like is not limited to the trapezoidal cross-sectional shape, and may be other shapes. In addition, the insertion direction of the connecting groove 17 is not limited to the vertical direction of the teeth 1, and particularly in the case of the back teeth, the insertion may be performed from the lateral direction of the teeth.
