Description

TECHNICAL FIELD [0001] The present invention relates to an orthodontic implant device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an implant device for orthodontic correction for moving a tooth by being fixed in an oral cavity.

In orthodontic treatment, securing of a fixation source is an important factor for guiding treatment to success, and various devices such as fixation of the jaw and fixation of the jaw have been conventionally used to enhance this. However, these devices have the drawback that the effect depends on the degree of cooperation of the patient. Thus, a method of moving a tooth with a bone as a fixation source (an implant anchor) has recently been devised and rapidly spread as a device that is part of a multi bracket system. As an implant anchor, a screw type is inexpensive and easy to use, and is widely used because of its very small surgical invasion at the time of implantation. However, screw-type implant anchors have a problem in that there is a limitation in the position of implantation and the implant anchor may be removed. Particularly, the upper side of the maxilla is located at a position where the root is inserted due to the proximity of the root of the adjacent tooth, the protrusion of the maxillary sinus between the root teeth, the width of the attached gingiva, and the like It is often limited. Even if the tooth is inserted into the alveolar bone between the narrow roots, the presence of the tooth may restrict the movement of the tooth. In addition, when the bone quality (bone quality) is poor, the dropout rate is increased. Therefore, the tooth root of the implant anchor and the gingiva of the anchor anchor that occurs when the implant anchor is dropped or inserted into the free gingiva There are many problems such as burial.

Recently, there has been proposed an implant device for orthodontic treatment in which a screw-type implant anchor is inserted into a palate which has good bone quality and has no limitation on the movement of the teeth. For example, Patent Document 1 discloses a configuration in which a through hole is formed at a position corresponding to a midline of a palate, a male thread is formed in the through hole, and both end portions in the longitudinal direction are cut And a dental orthodontic implant plate (orthodontic implant plate) configured to be connectable to a band for fixing the teeth. In Patent Document 2, a pair of screws provided with a male screw portion of a head are inserted into a palate, and a plurality of engaging holes are formed in the engaging hole of a base plate having a plurality of engaging holes projecting upward, Is screwed into the threaded portion of the threaded portion of the screw, the threadedly engaging member is screwed to the threaded portion of the threaded portion, the insertion hole of the upper structure having the inserted hole is inserted into the projected threaded portion of the base plate, There is disclosed an implant for orthodontics in which a joint member is fixed by screwing.

Japanese Unexamined Patent Application Publication No. 2006-314419 : Japanese Patent Publication No. 2008-183016

However, in the case where the implant plate for orthodontic appliances described in Patent Document 1 is directly fixed to the palate by the male screw, in the case of replacing and calibrating the plate with another shape, the male screw is pulled out and the new plate is fixed by the male screw There is a problem that the plate can not be easily changed.

According to the implant for orthodontics described in Patent Document 2, although the base plate and the upper structure can be exchanged with the screw inserted, since the size of the screw engagement member for fixing these members is extremely small, There is a problem that the operation of the washing machine is troublesome and that the washing machine may fall into the oral cavity when swapping and mistakenly swallow it.

It is an object of the present invention to provide an implant device for orthodontic treatment which is capable of easily detaching and attaching a wire for moving a tooth, The purpose.

An implant device for orthodontic treatment of the present invention is an orthodontic appliance for orthodontic treatment which is connected to an extension arm made of wire for moving a tooth and fixed in the oral cavity and includes a pair of anchor members fixed in the oral cavity, And a prismatic accommodating portion disposed in the bridge member and capable of inserting a prismatic wire, wherein the prismatic accommodating portion is provided with the extension portion, And a connecting member to which a part of the arm is inserted and connected.

Another orthodontic appliance for orthodontic treatment according to the present invention comprises a pair of anchor members fixed in the oral cavity, a bridge member formed to extend between the pair of anchor members and fixed to the pair of anchor members, A connecting member which is disposed on the bridge member and has a prismatic accommodating portion capable of inserting a prismatic wire, an arm portion which is made of a wire and fixed to the tooth and moves the tooth, And an extension arm having an insertion portion to be inserted into the extension arm.

1 is a view showing a configuration of an implant device 1 for orthodontic treatment according to an embodiment of the present invention. This orthodontic appliance 1 for orthodontic correction includes a pair of anchor members 10 fixed to the oral cavity, specifically to the mouth lid M1, A bridge member 20 formed to extend between the pair of anchor members 10 so as to extend between the pair of anchor members 10 and connected to the bridge member 20, And a connecting member 30 which can be inserted. This orthodontic appliance 1 for orthodontic correction is also made up of a wire and a part of which is inserted and connected to the connecting member 30 and another part of which is fixed to the tooth M2, an extension arm 40 may be provided.

Fig. 2 is a view showing the configuration of the anchor member 10, in which (A) shows a configuration viewed from the side, and Fig. 2 (B) shows a configuration viewed from the upper side. The pair of anchor members 10 includes a shaft 11 formed by a titanium alloy and having a screw thread formed thereon and a shaft 11 having one end And a head portion 12 formed on the head portion. Straight grooves 13 are formed on the side opposite to the shaft 11 in the head 12. [ The groove 13 is used for inserting and rotating a tool such as a driver when the anchor member 10 is inserted into the palate M1 and at the same time the anchor member 10 is inserted into the palate M1 And is used later to arrange the bridge member 20. It is preferable that the groove 13 is formed to extend from the peripheral edge portion of the head portion 12 to the peripheral portion facing the center portion and across the entire upper surface. So that the bridge member 20 is disposed.

The groove 13 has, for example, a pair of side surfaces (side surfaces) 13A and a bottom surface 13B therebetween. The pair of side surfaces 13A and the bottom surface 13B have a vertical relationship That is, at right angles to each other. For example, it is preferable that the cross-sectional shape on the plane perpendicular to the extending direction of the grooves 13 is formed to be a rectangular shape. The rectangle includes a square. The grooves 13 may be, for example, one set, but it is preferable that two grooves are formed so as to be orthogonal to each other at the center of the head 12. This is because it is easy to adjust so that the grooves 13 of the pair of anchor members 10 are located on the same straight line in order to arrange the bridge member 20.

Fig. 3 is a view showing a state in which the bridge member 20 is disposed on the anchor member 10, in which (A) shows a sectional configuration seen from the side and (B) shows a configuration seen from the upper side. It is preferable that the anchor member 10 is provided with a through hole 15 for allowing the ligature line 14 to pass through on the side of the head 12 in the shaft 11. [ The anchor member 10 and the bridge member 20 are ligated to each other by the ligation line 14 passed through the through hole 15 after the bridge member 20 is disposed in the groove 13, 20 can be fixed. The through hole 15 is formed so as to penetrate, for example, the shaft 11 in the width direction. The ligation line 14 is omitted in Fig.

4A and 4B are diagrams showing the configuration of the bridge member 20 and the connecting member 30, in which FIG. 3A shows a configuration from the upper side and FIG. 3B shows a cross-sectional configuration along the line I- Fig. The bridge member 20 is provided with a coupling portion (coupling portion) 21 that is fitted in the groove 13 of the pair of anchor members 10 and connects the pair of anchor members 10 . The engaging portion 21 is preferably made of a rectangular wire suitable for the groove 13, for example. The joining portion 21 is fixed to the anchor member 10 by a ligation wire 14 that has passed through the through hole 15 and is reinforced by a joining agent To be fixed to the anchor member 10. As the bonding agent, for example, plastic such as a photo-curing resin (photo-curing resin) is preferably used. At both ends of the engaging portion 21, for example, an annular portion 22 in which a square wire is bent in a ring shape is formed. The annular portion 22 is an advantageous structure for fixing an orthodontic appliance such as an elastique or a ligation wire and is intended to lower the risk of harm in the oral cavity. The bridge member 20 is preferably made of, for example, a square wire made of stainless steel (stainless steel).

The connecting member 30 is formed, for example, with a square prismatic receiving portion 31 made of stainless steel and capable of inserting a square wire. When the extension arm 40 is inserted into the prismatic accommodating portion 31, the extension arm 40 is prevented from rotating so as to be stabilized. The connecting member 30 is also provided with an arrangement hole 32 for inserting and arranging the engaging portion 21 of the bridge member 20, for example. The arrangement hole 32 is preferably formed in a prismatic shape corresponding to the engaging portion 21 made of, for example, a rectangular wire. The prismatic accommodating portion 31 and the arranging hole 32 are formed, for example, elongated in the extending direction of the connecting member 30. The cross-sectional shape on the plane perpendicular to the extending direction of the connecting member 30 is, for example, a rectangle. The connecting member 30 is preferably disposed, for example, between a pair of anchor members 10, and the length thereof is preferably in the range of 3 mm to 5 mm to stabilize the extension arm 40. The connecting member 30 is fixed to the engaging portion 21 by inserting and fastening the engaging portion 21 of the bridge member 20 into the arranging hole 32, for example.

Fig. 5 is a diagram showing the configuration of the extension arm 40. Fig. 5 (A) shows the entire configuration, and Fig. 5 (B) shows an enlarged view of the connection portion between the extension arm 40 and the connection member 30. Fig. The extension arm 40 includes an arm portion 41 which is fixed to the teeth and moves the teeth and an insertion portion 45 which is disposed in the arm portion 41 and is inserted into the prism- (Input portion) 42 as shown in FIG. The arm portion 41 is preferably made of stainless steel or a circular wire made of cobalt chrome (made of cobalt chrome). This is because the circular wire can be freely bent (bent) more easily than the square wire, and the shape of the circular wire is easily formed. It is preferable that the inserting portion 42 is formed by a rectangular wire made of stainless steel. The insertion portion 42 is joined to the arm portion 41 by soldering or the like when the arm portion 41 has a shape elongated laterally as shown in Fig. The arm portion 41 may have any shape and is determined according to the treatment contents. For example, when only one arm portion 41 is desired, the arm portion 41 and the inserting portion 42 may be formed successively by rectangular wires. The extension arm 40 may be manufactured by a dentist or the like according to the contents of the treatment. The extension arm 40 is fixed to the bridge member 20 by a ligation wire 43 after the insertion portion 42 is inserted into the prismatic accommodating portion 31 of the connection member 30, for example. The ligation lines 43 are omitted in Fig.

This implant device 1 for orthodontic correction is used, for example, in the following manner. First, as shown in Fig. 6, for example, a pair of anchor members 10 are inserted into the palate M1 of a patient who undergoes orthodontic correction. Specifically, for example, a tool such as a screwdriver is inserted into the groove 13 and the anchor member 10 is rotated to insert the tool. It is preferable to finally adjust the grooves 13 of the pair of anchor members 10 to be positioned on the same straight line. Further, even if the grooves 13 of the pair of anchor members 10 are deviated from the same straight line, it is possible to cope with the following procedure.

Subsequently, as shown in Fig. 7, for example, a bridge member 20 in which the connecting member 30 is disposed is prepared and fixed to the pair of anchor members 10. [ Concretely, for example, the engaging portion 21 of the bridge member 20 is fitted in the groove 13 of the pair of anchor members 10, and the engaging portion 21 is fixed by the ligature line 14. [ When the grooves 13 of the pair of anchor members 10 are displaced from the same straight line, the engaging portions 21 of the bridge member 20 can be bent and fitted into the grooves 13. Subsequently, as shown in Fig. 1, for example, an extension arm 40 is prepared, and the insertion portion 42 is inserted into the prismatic accommodating portion 31 of the connection member 30 as shown in Fig. 5 (B) And then fixed by the ligature line 43. [ Further, the arm portion 41 of the extension arm 40 is fixed to the tooth M2 to be moved. The orthodontic treatment is performed accordingly.

When it is necessary to change the shape of the extension arm 40 according to the progress of the treatment, the extension arm 40 is replaced. That is, the extension arm 40 inserted in the connecting member 30 is removed, and the new extension arm 40 is inserted into the connecting member 30. Also, the arm portion 41 of the extension arm 40 is manufactured by an arbitrary wire according to the treatment contents.

As described above, according to the present embodiment, since the connecting member 30 having the prism-like receiving portion 31 for inserting the square wire is provided, the insertion portion 42 made of the square wire of the extension arm 40 It is possible to stably fix the extension arm 40 to the palate M1 without rotating it by inserting it into the prismatic accommodating portion 31. [ Therefore, the extension arm 40 can be easily attached and detached, and can be easily replaced according to the progress of the treatment. Further, since the extension arm 40 can be formed by a wire, it can be easily processed according to the patient and the price can be reduced.

A groove 13 having a vertical relationship between the side surface 13A and the bottom surface 13B is formed in the head portion 12 of the anchor member 10 and a joint portion 21 made of a square wire is formed on the bridge member 20, The bridge member 20 can be easily and stably placed on the anchor member 10 by fitting the engaging portion 21 into the groove 13 of the anchor member 10.

While the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment but can be variously modified. For example, although each component has been described in detail in the above embodiments, it may not include all the components or may include other components. Further, each component may have another configuration. In addition, the anchor member 10 is not limited to the palate M1 but may be a portion having an attached gingiva in the oral cavity and not interfering with the movement of the tooth, for example, an edentulous ) Can be fixed to the top of the alveolar ridge.

The present invention can be used for orthodontic correction.
