Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dental implant,

The present invention relates to an angle adjusting tool for adjusting the angle of a dental implant used for restoring a lost tooth of a patient.

Implant refers to a replacement that restores the lost human tissue. In the dentist, a fixture is implanted in the alveolar bone that has been removed from the natural root to replace the root (root) of the lost tooth, (I. E., Prosthesis) to restore the original function of the tooth.

Such dental implants can be classified into various types according to the method of bonding the artificial teeth and the root teeth. Among them, there are screw type implants using the screw coupling force. The conventional screw type implant system (implant assembly) is composed of a fixture, an abutment and an artificial tooth.

The fixture is immersed in the alveolar bone and serves to fix the entire implant system, and is made of titanium or the like having excellent biocompatibility for fusion with the human bone tissue. The abutment is attached to the fixture and serves to fix and support the artificial tooth. Artificial teeth are made in the form of teeth through processes such as impression making, work modeling, lead-making, burial and summoning.

The fixture and abutment may be integrally formed, or may be formed as separate parts and then joined together.

Fig. 1 shows an example of a monolithic implant in which a fixture and an abutment are integrally formed. 1 includes a fixture 1 immersed in an alveolar bone, an abutment 5 as an upper structure integrally formed on the upper portion of the fixture 1, A fixed prosthesis, that is, an artificial tooth (not shown).

However, the integral implant having the fixture and the abutment piece formed integrally can not change the direction of the abutment when the direction of the insertion is wrong or the direction of the implantation is different from that of the artificial tooth. There has been a problem that it is necessary to perform troublesome operations to remove the abutment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an angle adjusting tool of a dental implant according to an embodiment of the present invention will be described in detail with reference to the drawings.

The angular adjustment tool of the dental implant according to the embodiment of the present invention can adjust the angle of the implant, that is, the angle between the fixture 11 and the abutment 12, when necessary, even after the implant is implanted, between the fixture and the abutment The implant can be used together with the integral implant 10 having the recess 13 capable of adjusting the angle.

1 to 6, the angle adjusting tool of the dental implant according to the first embodiment of the present invention includes an upper portion of the monolithic implant having the concave portion 13, that is, the abutment 12, A bending member 20 for allowing the operator to adjust the angle of the implant by applying a force while being coupled to the bending member 20 and a bending member 20 which is detachably coupled to the bending member 20 and which is fitted to the outer surface of the integral- And a guide member 30 for stopping further angle adjustment.

The bending member 20 includes a cylindrical bag portion 21 to be held by the operator and an insertion portion 22 into which the abutment 12 of the integral implant 10 is inserted. An insertion hole 23 is formed in the insertion portion 22 so as to have a shape corresponding to the shape of the abutment 12 of the integral implant 10 and to insert a part of the upper end of the abutment 12 therein.

It is not necessary that the abutment 12 is completely inserted into the insertion hole 23 and it is sufficient that a part of the upper end of the abutment 12 can be inserted so that the practitioner can apply force. As shown in Figs. 4 to 6, the insertion hole 23 has a tapered shape with its inner diameter increasing toward the distal end, that is, toward the entrance of the insertion hole 23. [

The outside of the insertion portion 22 has a tapered shape with an outer diameter becoming smaller toward the distal end over at least a part of the section. The thickness between the inner surface and the outer surface of the insert 22 becomes gradually thinner toward the distal end.

The guide member 30 includes a fitting portion 34 to which the insertion portion 22 of the bending member 20 is fitted and fitted and a stopping portion 35 extending from the fitting portion 34.

The fitting portion 34 has a shape corresponding to the insertion portion 22 of the bending member 20 having a tapered shape as described above. That is, the inner peripheral surface of the fitting portion 34 has a tapered shape corresponding to the insertion portion 22.

The stopper portion 35 extends from the fitting portion 34 by a predetermined length and has a substantially semicircular shape in cross section. When the angle between the fixture 11 and the abutment 12 reaches a predetermined angle when the practitioner applies force to adjust the angle of the integral implant 10, that is, when the concave portion 13 of the integral implant is bent, The distal end portion of the stopper 35 abuts against the outer surface of the integral implant 10 so that the recess 13 can no longer be bent.

At this time, no thread is formed in the portion of the integral implant 10 where the distal end portion of the stopper 35 abuts, that is, the portion of the fixture 11 adjacent to the concave portion 13, and the outer surface is smooth or flat The contact portion 14 may be formed. Although the illustration shows the abutment portion 14 as having a plurality of flat surfaces and having the shape of a nut or bolt head, this is only an example, and the abutment portion 14 may not be formed separately.

When the length of the stopper 35 is changed, the degree of bending of the recessed portion 13 can be changed. That is, when the length of the stopper portion 35 is relatively short, the concave portion 13 must be bent relatively much before the distal end portion of the stopper portion 35 touches the abutting portion 14, The axis has a relatively large angle relative to the center axis of the fixture. Conversely, if the length of the stopper 35 is relatively long, the concave portion 13 must be bent relatively less until the distal end portion of the stopper portion 35 comes into contact with the abutment portion 14, The central axis has a relatively small angle relative to the center axis of the fixture. Therefore, several guide members 30 having different lengths of stopper portions 35 are prepared and prepared, and if necessary, the degree of bending of the recess portion 13 by selectively using the guide member 30 having an appropriate length May be adjusted.

Although the figure shows that there is no coupling means between the insertion portion 22 of the bending member 20 and the fitting portion 34 of the guide member 30, it is possible to utilize a snap coupling method or a screw coupling method So as to prevent accidental departure. When a male screw portion is formed on the outer periphery of the insertion portion 22 and a female screw portion is formed on the inner periphery of the insertion portion 34 by using a screw type fastening method, The same effect as that of the stopper 35 may be obtained.

FIG. 6 shows a procedure of performing an operation using the angle adjusting tool of the dental implant according to the present embodiment.

6 (a), the practitioner inserts the insertion hole 23 formed in the insertion portion 22 of the bending member 20 in a state where the bending member 20 and the guide member 30 are engaged with each other, The abutment 12 of the integral implant 10 is inserted.

6 (b), the practitioner applies a force to the bending member 20 so that the stopper 35 of the guide member 30 contacts the abutment portion 14 of the integral-type implant 10 The concave portion 13 is bent until reaching. At this time, since the fixture 11 is fixed in the bone B, the practitioner can bend the concave portion 13 by exerting a force only on the abutment 12.

As shown in Fig. 6 (c), when the angle adjustment of the implant is completed, the angle adjusting tool is detached from the abutment 12.

As described above, according to the first embodiment of the present invention, when the practitioner applies force to adjust the angle of the implant, the angle adjusting tool of the dental implant abuts the outer surface of the implant so that the concave portion of the implant is excessively bent It is possible to prevent the concave portion of the implant from being broken. In addition, the angle of the implant can be precisely adjusted to the angle desired by the operator.

FIG. 7 shows a dental implant angle adjusting tool according to a modification of the first embodiment of the present invention. The angle adjusting tool of the dental implant according to the modified example of the first embodiment is a device for adjusting the angle of the implant by applying a force to the implant so as to adjust the angle of the implant in a state of being coupled to the abutment 12, And a guide member (40) detachably coupled to the bending member (20) and abutting against the outer surface of the integral implant (10) at the time of angle adjustment to stop further angle adjustment.

Also in the modification of the first embodiment, the guide member 40 also includes the fitting portion 44 to which the insertion portion 22 of the bending member 20 is fitted and engaged, (45), as in the first embodiment.

However, the stop portion 45 of the guide member 40 is made to have an arc shape in section in the above-described first embodiment, while in the modification of the first embodiment, the end surface is made to have a perfect circular shape There is a difference in the point. Accordingly, the guide member 40 according to the modification of the first embodiment has a generally cylindrical shape in its outer shape.

When the guide member 30 as in the first embodiment is used, it is necessary to consider the direction in which the force is applied before the angle adjusting tool is inserted into the abutment 12, and the stopper 35 of the guide member 30 It should be oriented so that it is positioned on the bent side. However, in the case of using the cylindrical guide member 40 as in the modification of the first embodiment, it is not necessary to consider the bending direction before putting the angle adjusting tool into the abutment 12, It is convenient.

The angle adjusting tool of the dental implant according to the modification of the first embodiment is the same as that of the first embodiment except for the shape of the stopper 45. Therefore, the detailed description of the same parts will be omitted for the sake of convenience.

8 shows a dental implant angle adjustment tool according to a second embodiment of the present invention. The angular adjustment tool of the dental implant according to the second embodiment is similar to that of the first embodiment described above except that the angular adjustment tool of the dental implant according to the second embodiment includes a bending member And a guide member 60 detachably coupled to the bending member 50 and abutting against the outer surface of the integral implant 10 at the time of angle adjustment to stop further angle adjustment.

However, unlike the first embodiment in which the bending member and the guide member are separately formed and detachably coupled to each other, in the second embodiment, the bending member 50 and the guide member 60 are integrally formed do. Therefore, in the angle adjusting mechanism of the second embodiment, a configuration for coupling between the bending member 50 and the guide member 60 is not required.

The bending member 50 according to the second embodiment includes a cylindrical bag portion 21 to be held by a practitioner and an insertion portion 52 into which the abutment 12 of the integral implant 10 is inserted. An insertion hole 53 is formed in the insertion portion 52 so as to have a shape corresponding to the shape of the abutment 12 of the integral implant 10 and to insert a part of the upper end of the abutment 12 therein.

It is not necessary that the abutment 12 is completely inserted into the insertion hole 53 and it is sufficient that a portion of the upper end of the abutment 12 can be inserted so that the practitioner can apply force as in the first embodiment described above . As shown in Fig. 8, the insertion hole 53 has a tapered shape in which the inner diameter increases toward the distal end, that is, toward the entrance of the insertion hole 53. As shown in Fig.

The guide member 60 according to the second embodiment includes the stop portion 65 extending from the insertion portion 52 of the bending member 50. [

As in the first embodiment described above, the stop portion 65 extends from the insertion portion 52 by a predetermined length and has a substantially semicircular shape in cross section. When the angle between the fixture 11 and the abutment 12 reaches a predetermined angle when the practitioner applies force to adjust the angle of the integral implant 10, that is, when the concave portion 13 of the integral implant is bent, The distal end portion of the stopper 52 abuts against the outer surface of the integral implant 10 so that the recess 13 can no longer be bent.

When the bending member 20 and the guide member 30 are detachably coupled as in the first embodiment, care must be taken to prevent the engagement state from being accidentally released during the procedure. However, in the case of using the integral-type angle-adjusting tool as in the second embodiment, there is no fear that the engagement state is released, so that the operation can be facilitated.

Fig. 9 shows a dental implant angle adjustment tool according to a modification of the second embodiment of the present invention. The angle adjusting tool of the dental implant according to the modification of the second embodiment is similar to that of the above-described second embodiment in that the angle adjusting means of the dental implant is bent And a guide member 70 formed integrally with the bending member 50 and abutting against the outer surface of the integral implant 10 at the time of angle adjustment to stop further angle adjustment.

Also in the modified example of the second embodiment, the guide member 70 is the same as that in the second embodiment in that it includes a stopper portion 75 extending from the insertion portion 52.

However, the stop portion 75 of the guide member 70 is made to have an arc shape in cross section in the above-described second embodiment, whereas in the modification of the second embodiment, the cross section is made to have a complete circular shape There is a difference in the point. Accordingly, the guide member 70 according to the modified example of the second embodiment has a cylindrical shape as a whole.

In the case of using the angle adjusting mechanism having the guide member 60 as in the second embodiment, it is necessary to consider in which direction the force is applied before the angle adjusting tool is inserted into the abutment 12, The portion 65 should be oriented so as to be positioned on the bent side. However, in the case of using the cylindrical guide member 70 as in the modification of the second embodiment, it is possible to apply force in any direction without having to consider the bending direction before putting the angle adjusting tool into the abutment 12 It is convenient.

The angle adjusting tool of the dental implant according to the modification of the second embodiment is the same as the second embodiment except for the shape of the stopper 75. Therefore, detailed description of the same parts will be omitted for the sake of convenience.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various modifications and changes may be made by those skilled in the art.
