Description

A fitting jig for healing abutment

The present invention relates to a jig for mounting a heel abutment, and more particularly, to a jig for mounting a healing abutment, which has improved binding force with a healing abutment and is stably installed in an intraoral treatment site, To an abutment mounting jig.

Generally, an implant refers to a substitute for replacing a human tissue when the original human tissue is lost, but refers to implanting an artificial tooth in the dentistry. In other words, a fixture made of titanium or the like that does not have a rejection reaction to the human body can be substituted for the lost root, and the tooth is put in the alveolar bone that has passed through the tooth, and then the artificial tooth is fixed to restore the function of the tooth.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants can prevent damage to the surrounding dental tissues and can be used stably because there is no secondary cause of tooth decay. In addition, since the implant has the same structure as the natural teeth, there is no pain or foreign body sensation of the gums, and the implant can be used semi-permanently only if it is managed properly.

Here, the implant procedure includes a first procedure in which a fixture is placed in an alveolar bone, a second procedure in which a fixture is held for a period of time (3 to 6 months) .

In detail, the primary procedure includes a gum removing step of opening the gum of a tooth missing part, a multi-step drilling step of forming a perforation to which the fixture is to be inserted, and a step of fitting the temporary teeth to the fixture placement step and the inserted fixture .

After the first-time procedure, a temporary restoration period for the bone fusion is performed. Then, the temporary teeth joined to the fixture are separated, the gums around the temporary teeth are removed, and the second procedure for inserting and fixing the final restoration is performed Thereby completing the implant procedure.

In recent years, for the aesthetic gum formation, a healing abutment is fastened between the fixture and the temporary tooth during the primary procedure. Here, the healing abutment is preceded and fastened before the abutment is fastened to the fixture so that the gums are cleanly formed to the upper side of the fixture. After about 2 to 3 weeks, the abutment is removed again and the abutment is joined do.

1A and 1B are schematic views showing a method of mounting a conventional healing abutment. The healing abutment h comprises a body part 3 formed in a predetermined shape for esthetic gingival formation and a body part 3 extending downward from the body part 3 and formed on the inner peripheral surface of the upper end of the fixture, And an engaging portion 5 that is formed to be in conformity with the engaging portion 5.

A through hole (1) is formed through the central portion so that a fastening screw for fixing the healing abutment (h) to the fixture is inserted. Thus, the healing abutment h formed as described above can be moved to the intraoral site, and fixed by the fixture and the fastening screw installed in the treatment area.

At this time, since the healing abutment h is a part that comes into direct contact with the perforated gum for the treatment, a high degree of cleanliness and hygiene are required. Thus, conventionally, the method of moving the healing abutment h to the intraoral site is as follows.

In detail, the healing abutment h is provided with a fastening driver (a) to be screwed by the fastening screw after being transferred to the intraoral treatment site. As shown in FIG. 1A, the coupling groove 2 and the coupling protrusion b are formed at the front end of the coupling driver a, So that the healing abutment h can be moved to the intra-oral treatment site as it is elastically frictionally engaged.

However, when the frictional force between the engaging groove 2 and the engaging projection b is small, there is a problem that the healing abutment h is separated from the engaging screw (a) and dropped to the floor or the like. On the contrary, when the frictional force between the engaging groove 2 and the engaging projection b is large, it is difficult to separate the engaging driver a from the healing abutment h. In order to separate the engaging driver a from the healing abutment h, There was a problem that the abutment h was caught.

1B, the jig 10 may be moved by using the jig 10 provided with the support protrusion 11 elastically frictionally engaged with the outer surface of the body part 3. However, The heel abutment h is disengaged from the jig 10 when the frictional force between the cut parts 4 cut on the outer periphery of the body part 3 is small. Further, when the jig 10 is detached from the healing abutment h, the hand of the operator comes into contact with the outer surface of the body part 3, and the healing abutment h is contaminated.

2 to 4, the jig 100 for mounting a heel abutment according to the present invention includes a jig body 110 and a jig spring 120.

Meanwhile, the healing abutment h is fastened prior to fastening the abutment to the fixture (6 in Fig. 5A) so that the gums are cleanly formed on the fixture (6 in Fig. 5A) A body portion 3 which is formed in a predetermined shape to guide the regeneration form of the gum, and an upper end portion of the fixture (6 in Fig. 5) As shown in Fig. Here, the healing abutment h may be made of biocompatible material such as titanium or polyether ketone for medical use.

In detail, a fastening hole 1 through which a fastening screw is inserted is formed at the center of the healing abutment h. That is, the fastening screw inserted into the fastening hole 1 is screwed into a screw groove formed in the fixture so that the healing abutment h is fixed to the upper end of the fixture 6 (FIG. 5A) .

A plurality of cut portions (4) are formed along the outer peripheral surface of the body portion (3). Herein, the de-cut part 4 is a placement orientation reference part for placement and shape recognition during oral scan for implant treatment. The heal abutment h is engaged with a jig used when attaching the healing abutment h to the intraoral site It can also be used as a binding site.

At this time, the de-cut part 4 may be cut in the form of a cut in a uniformly divided position along the outer peripheral surface of the body part 3, . In addition, the direction in which the healing abutment h is fastened to the intra-oral treatment site can be confirmed by using the directionality of the de-cut part 4 as the case may be.

In this case, since the healing abutment h is a part directly contacting the perforated gum for implant treatment, a high level of hygiene and cleanliness are required. In the present invention, the sanitary property and the attachment property of the healing abutment h are Thereby providing an improved structure of the jig.

In detail, the jig body 110 may be formed in a shape substantially corresponding to the sectional shape of the healing abutment h. The jig body 110 may be made of a biocompatible metal such as titanium. The jig body 110 may be elastically connected to the healing abutment h and may be formed on the outer surface of the healing abutment h. It may be made of a biocompatible synthetic resin material so as not to cause scratches.

A through hole 111 is formed at the center of the jig body 110 along the longitudinal direction. In detail, the jig body 110 is engaged with the upper end of the body part 3 to move the healing abutment h to the intraoral site. At this time, the through hole 111 is used as a passage through which a fastening screw (8 in FIG. 5B) for connecting the fixture (6 in FIG. 5A) and the healing abutment (h) The end of the fastening screw (8 of FIG. 5B) inserted through the through hole 111 is screwed to the fixture 6 (FIG. 5A) to connect the healing abutment h. 5B), the diameter of the through hole 111 is adjusted by the fastening screw (8 in FIG. 5B) or the screw (not shown in FIG. 5B) so that the fastening screw May be formed larger than the diameter of the fastening driver (Fig. 5 (a)).

A plurality of coupling protrusions 112 protrude from one end of the jig body 110. The coupling protrusion 112 protrudes at a predetermined interval along the outer periphery of the end of the jig body 110 and one end of the body 3 is inserted into the coupling protrusion 112 A mounting space is formed.

The healing abutment h is formed by cutting a plurality of the cut portions 4 along the outer periphery of the body portion 3. The inner surface of the coupling protrusion 112 is formed with a cut- 4) is formed on the inner surface of the elastic member (113). That is, since the outer surface of the de-cut part 4 and the resilient mating surface 113 are in close contact with each other and elastically fixed, the mounting of the healing abutment h is easy.

Since the coupling protrusion 112 protrudes in a shape corresponding to the cut portion of the cut portion 4 cut in the form of a cut, the outer peripheral profile of the coupling protrusion 112 and the outer peripheral profile of the body portion 3 Can be formed into a substantially continuous shape. For example, a plurality of cut portions 4 are cut along the outer peripheral surface of the healing abutment h having a circular cross section, and the coupling protrusions 112 are formed on the dies 4 of the healing abutment h, The outer surface of the body part 3 exposed between the coupling protrusions 112 and the coupling protrusions 112 can be formed into a substantially continuous circular shape.

At this time, since the jig body 110 is made of a synthetic resin material, the outer surface of the elastic part 113 and the de-cut part 4 are elastically fixed, and the outer surface of the body part 3 is smoothly pressed, It is possible to prevent the occurrence of scratches. In addition, since each of the dies 4 and the coupling protrusions 112 are formed to correspond to each other, the healing abutment h can be connected to the upper end of the fixture 6 in the correct direction, The gums may be formed in a desired shape corresponding to the shape of the body part 3. [

The jig body 110 and the body part 3 are elastically fixed by a frictional force between the resilient mating surface 113 and the dick part 4. The resilient mating surface 113 and the di- It is preferable that the jig spring portion 120 is provided so that the elastic force of the cut portion 4 is reinforced.

The jig spring 120 is formed in a ring shape so as to surround the outer circumference of the coupling protrusion 112 and is fitted to one end of the jig body 110 protruding from the coupling protrusion 112. [ Here, the above-mentioned ring shape is preferably understood as a hollow pipe shape in which the inside is penetrated so as to be substantially coincident with the outer circumference of the coupling protrusion 112. [ Further, the hollow pipe shape may have a circular, elliptical or polygonal cross-section, and the inner circumferential surface shape of the jig spring part 120 may be formed to correspond to the outer surface of the healing abutment h, Sectional shape that substantially coincides with the outer surface of the body portion 110.

When the healing abutment h is inserted into the coupling protrusion 112 by pressing the coupling protrusion 112 elastically by the inner circumferential surface 121 of the jig spring part 120, Can cover the outer surface of the coupling protrusion 112 to prevent the coupling protrusion 112 from spreading outward.

The inner circumferential surface 121 of the jig spring part 120 may be in close contact with the outer surface of the body part 3 exposed between the plurality of coupling protrusions 112. In detail, the healing abutment h can be elastically fixed on the outer surface of the de-cut part 4 formed on the body part 3, The inner circumferential surface 121 of the ring-shaped jig spring portion 120 covers the outer surface of the coupling protrusion 112 and elastically pressurizes the inner circumferential surface of the coupling portion 112 of the body portion 3 exposed between the coupling protrusions 112 And can be elastically adhered to the outer surface.

That is, the healing abutment h is formed in such a manner that the de-cut part 4 formed on the body part 3 is elastically fixed to the coupling protrusion 112, and the heel abutment h is formed on the inner peripheral surface 121 of the jig spring part 120 The outer surface of the body part 3 exposed through the coupling protrusions 112 may be elastically adhered. As the entire outer surface of the body part 3 is substantially elastically fixed, the binding force between the healing abutment h and the attaching jig 100 is improved, so that the healing abutment h is inserted into the oral cavity You can safely move to the procedure site.

The inner circumferential surface 121 of the jig spring part 120 elastically contacts the outer surface of the body part 3 and presses the outer circumference of the coupling protrusion 112 elastically, It is possible to reinforce the elastic fixing force with the dick portion 4, so that the healing abutment h is more firmly attached, so that it is possible to prevent the attachment from the attachment jig 100.

Meanwhile, it is preferable that a variable slot groove 123 is formed at one end edge 122 of the jig spring 120. More specifically, the jig spring portion 120 may have one end portion of the jig body 110 protruding from the coupling protrusion 112 so as to reinforce the binding force between the jig body 110 and the healing abutment h, . The jig spring 120 is inserted into the coupling protrusion 112 of the jig spring 120 so that the healing abutment h can be easily inserted into the coupling protrusion 112 of the jig spring 120, The variable slot grooves 123, which are cut out to a predetermined length, are formed on both sides of mutually opposed sides. Thus, when the healing abutment h is inserted between the coupling protrusions 112, the interval of the variable slot grooves 123 is elastically expanded so that the diameter of the one end edge 122 of the jig spring portion 120 So that the healing abutment h can be easily inserted.

Here, the length of the variable slot groove 123 may be set to a position corresponding to a middle point of the length of the jig spring 120. When the variable slot groove 123 is elongated such that it is close to the other end of the jig spring 120, the diameter of the end 122 of the jig spring 120 is enlarged, The force that causes the coil spring 123 to be opened is applied to the end portion of the variable slot groove 123, so that the durability may be deteriorated. As a result, the jig spring portion 120 can not stably press the outer surface of the coupling protrusion 112 and the end of the variable slot groove 123 is broken, thereby causing the jig spring portion 120 to be damaged. .

In contrast, when the variable slot groove 123 is formed to be short in the vicinity of the one end rim 122, when the healing abutment h is inserted into the attachment space, the one end rim of the jig spring portion 120 An excessive force is required to insert the healing abutment h because the diameter of the healing abutment 122 does not expand effectively. Therefore, the variable slot groove 123 is preferably cut to the middle point of the width of the jig spring portion 120, so that the healing abutment h can be easily inserted into the mounting space.

At this time, the jig spring 120 may be made of a biocompatible metal material such as titanium, like the jig body 110, and may be elastically connected to the healing abutment h, It is also possible to make a biocompatible synthetic resin material so as not to cause scratches on the outer surface of the healing abutment (h).

In detail, when the healing abutment h is inserted into the mounting space between the coupling projections 112, the variable slot groove 123 is formed, so that the edge 122 of the jig spring 120, Can be elastically expanded. Therefore, the healing abutment h is easily inserted into the mounting space between the coupling projections 112. After the healing abutment h is inserted, one end of the jig spring portion 120 The sub-rim 122 can be restored to its original diameter by the elastic restoring force. The inner circumferential surface 121 of the jig spring 120 can elastically press the coupling protrusion 112 and the outer surface of the body 3 according to the restoring force as described above.

In other words, the healing abutment h can be elastically expanded and contracted corresponding to the outer periphery of the healing abutment h according to the opening width of the variable slot groove 123, so that the healing abutment h can be quickly and safely attached.

In addition, the one end edge 122 of the jig spring portion 120 is elastically expanded by the variable slot groove 123 opened to a predetermined length, and the other end edge is integrally formed, And can be tightly coupled to the portion 110. When the healing abutment h and the attaching jig 100 are separated after the healing abutment h is fixed to the fixture placed in the intraoral treatment region, Can be prevented from being separated from the jig body 110.

In the jig 100 for healing abutment attachment according to the present invention, the jig spring part 120, which is engaged with one end of the jig body part 110, contacts the inner surface of the coupling protrusion 112, The outer surface of the de-cut portion 4 of the portion 3 is elastically pressed by once again surrounding the outer periphery elastically adhered to each other, so that the healing abutment h can be firmly attached.

At this time, the inner circumferential surface 121 of the jig spring part 120 elastically presses the outer surface of the coupling protrusion 112 and elastically contacts the outer surface of the body part 3 exposed between the coupling protrusions 112 The healing abutment h can be stably mounted.

The variable slot groove 123 is formed at both ends of one end 122 of the jig spring 120 so that when the healing abutment h is inserted between the coupling projections 112, The diameter of one end edge 122 of the jig spring portion 120 surrounding the outer surface of the jig spring portion 120 is elastically expanded so that the healing abutment h is easily inserted, So that the healing abutment h can be quickly and safely attached to the body portion 3 by elastically pressing the coupling protrusion 112 and the outer surface of the body portion 3. [

The jig body 110 may further include a coupling display surface 114 for visually confirming a protruding position of the coupling protrusion 112 inserted into the jig spring 120. The joint display surface 114 may be formed in a cut shape along the outer periphery of the jig body 110 and may be formed by forming a cylindrical member having the joint display surface 114 formed therein, And may be fitted to the outer surface of the jig body 110.

At this time, the position where the decut is formed is formed at a position continuous with the coupling protrusion 112 in the longitudinal direction. That is, since the coupling display surface 114 is used as a mark indicating the position of the coupling protrusion 112 inserted into the jig spring 120, it is possible to confirm the coupling display surface 114 The coupling protrusion 112 and the de-cut portion 4 formed on the body portion 3 can be accurately combined.

Thus, since the coupling display surface 114, the coupling protrusion 112, and the de-cut portion 4 formed on the body portion 3 of the healing abutment h can be aligned substantially in a straight line, Even if the coupling protrusion 112 is covered by the jig spring portion 120, the position of the dies portion 4 of the body portion 3 and the coupling display surface 114 can be visually checked for quick and accurate mounting .

The jig spring 120 may extend to a predetermined length so as to cover the outer surface of the body 3 and the coupling protrusion 112. In detail, the jig spring portion 120 is fitted to surround the outer surfaces of a plurality of the coupling protrusions 112 protruding from one end of the jig body 110. The healing abutment h is inserted between the coupling protrusions 112. The jig spring 120 is extended to a predetermined length so that the outer surface of the body part 3 is substantially shielded from the outside .

Thus, even if the operator holds the jig body 110 by hand, the hand or glove of the operator is prevented from contacting the outer surface of the healing abutment h by the jig spring portion 120, The hygienic properties of the patch (h) can be remarkably improved. At this time, since the variable slot groove 123 is opened in the form of a narrow incision groove, the operator's hand or glove contacting the outer surface of the healing abutment h due to the gap between the variable slot grooves 123 is substantially Can be blocked.

That is, the jig spring portion 120 firmly fixes the healing abutment h to improve the attaching property and serves as a cover for shielding the outer surface of the healing abutment h from the external environment Since the healing abutment h can be quickly and easily attached, the time required for implant treatment can be remarkably shortened. Moreover, since the hands of the practitioner are prevented from being contaminated, the hygienic properties are remarkably improved, and the amount of the healing abutment (h) which is contaminated and discarded can be remarkably reduced, thereby improving the economical efficiency.

At this time, the jig body portion 110 is fitted on the outer circumference of the jig body portion 110 so as to limit the overlapping width of the one end portion of the jig body portion 110 and the jig spring portion 120, And a restricting step portion 115 in which the end portion of the end portion is engaged is formed.

In detail, the jig spring part 120 may be inserted into and engaged with the jig body 110 from the one end of the jig body 110 in which the coupling protrusion 112 protrudes in the other end direction. When the jig spring part 120 is fitted to the jig spring part 120 by applying an excessive force to the jig spring part 120 so as to enclose the outer surface of the coupling protrusion 112, The fixing force for pressing the healing abutment h can not be transmitted. Further, since the outer surface of the body portion 3 of the healing abutment h, to which the jig spring portion 120 is inserted into the attaching space inside the coupling projections 112, is exposed to the external environment, May be contacted and contaminated.

Therefore, the jig body 120 is inserted into the jig body 110 so that the position where the jig is locked is limited to a position surrounding the outer surface of the coupling protrusion 112, A restricting step portion 115 may be formed.

At this time, the restricting step jaw portion 115 may be formed as a step protruded integrally along the outer periphery of the jig body portion 110, and in some cases, a separate protruding member may be formed on the outer circumference of the jig body portion 110 It can also be fitted together. Further, the restricting step jaw portion 115 may be formed to protrude in a ring shape along the outer periphery of the jig body portion 110, or may be protruded at least in the form of a narrow protrusion depending on the case.

When the jig spring part 120 is fitted into one end of the jig body part 110, the jig spring part 120 is engaged with the coupling protrusion 112, As shown in FIG. As shown in the drawing, the jig body 110 may be formed as a step at the end of the joint display surface 114, or may be provided at a position where the jig spring 120 can restrain the above- As shown in Fig.

More specifically, the variable slot groove 123 is formed at one end edge 122 of the jig spring portion 120 to facilitate mounting of the healing abutment h, and at the other end edge of the jig spring portion 120, (120) may be engaged with the restricting end jaw (115). The jig spring 120 may be inserted into one end of the jig body 110 so that the position of the restricting step jaw portion 115 is limited by the position of the jig spring portion 120, 112) in a direction substantially perpendicular to the longitudinal direction. Thus, the inner circumferential surface of the jig spring part 120 is resiliently brought into close contact with the coupling protrusion 112 and the outer surface of the body part 3, thereby elastically fixing the healing abutment h Alternatively, the outer surface of the body part 3 may be shielded from the external environment so that the sanitary property may be remarkably improved.

The grip portion 116 may be provided at the other end of the jig body 110. Here, the grip portion 116 protrudes in the radial direction along the outer circumference of the other end of the jig body 110, and a plurality of recessed grooves 116a may be formed. Of course, the grip portion 116 may be formed at the other end of the jig body 110 in a state where the plurality of recessed grooves 116a are recessed, and such modifications are within the scope of the present invention.

At this time, the grip portion 116 formed with the concavo-convex groove 116a can prevent the operator's hand from slipping when the operator holds the hand, and when the jig body 110 is rotated from side to side, It is possible to provide a rugged feeling at the fingertip for easy manipulation. Thus, not only can the jig body 110 be stably picked up, but also it is possible to rotate the jig body 110 finely left and right so that the operability can be remarkably improved.

5A and 5C are schematic views illustrating a method for mounting a healing abutment using a jig for attaching a healing abutment according to an embodiment of the present invention.

As shown in FIGS. 5A to 5C, the healing abutment can be connected to the upper end of the fixture placed in the oral cavity using a jig for mounting a healing abutment according to the present invention.

5A to 5C, the healing abutment h is attached to the upper portion of the fixture 6 placed in the intraoral region using the jig 100 for attaching the healing abutment according to the present invention. You can connect.

In detail, the body portion 3 is inserted into a plurality of coupling protrusions 112 protruding from one end of the jig body 110. At this time, a plurality of de-cut parts 4 are formed along the outer periphery of the body part 3, and the coupling protrusions 112 protrude at positions corresponding to the de-cut parts 4 at one end of the jig body part 110 do. Thus, the inner surface of the coupling protrusion 112 and the outer surface of the de-cut portion 4 can be resiliently fixed.

Here, the jig spring portion 120 is provided to reinforce the elastic force between the inner surface of the coupling protrusion 112 and the outer surface of the decoup portion 4, and the jig spring portion 120 is engaged with the coupling protrusion 112 And the healing abutment h can be more stably combined with the outer surface of the body part 3 exposed between the coupling projections 112. [

The variable slot groove 123 is formed at both ends of one end rim 122 of the jig spring portion 120 so that the healing abutment h can be easily inserted into the jig spring portion 120, So that the healing abutment h and the coupling protrusion 112 can be pressed to provide a firm coupling force.

The healing abutment attachment jig 100 to which the healing abutment h is attached as described above can be picked up by a practitioner and transferred to the intraoral treatment site. At this time, since the jig spring part 120 is extended to a predetermined length to shield the outer surface of the body part 3 of the healing abutment h, the hands or gloves of the practitioner can be prevented from being used.

On the other hand, the healing abutment h transferred to the intraoral treatment part is engaged with the upper end of the fixture 6. At this time, an engaging portion 5 extends to an end of the healing abutment h so as to engage with an upper end of the engaging groove of the fixture.
