A dental implant (hereinafter simply referred to as an "implant ") is also called an artificial tooth or a third tooth. That is, the implant is a dental treatment method that restores the function of a natural tooth by implanting a biocompatible material, such as a titanium-based metal artificial tooth, on a defective portion of a tooth or a jaw of a tooth extracted from the tooth, or It refers to the artificial tooth itself.

These implants have a variety of structures, and basically consist of fixture, abutment, and artificial crown elements, as can be seen from various known documents. The fixture is formed as a screw of a material having excellent biocompatibility and is embedded in the alveolar bone that has lost teeth and is osseointegrated. The abutment is an upper structure on which an artificial crown for chewing and beauty is mounted, It is screwed or screwed into the fixture.

When the operation of implanting the fixture in the alveolar bone is completed, the healing abutment is fastened to the fixture immediately when the alveolar bone is in good condition. The healing abutment protects the fixture until the artificial crown is raised, and acts as a gum forming to match the gum shape to the abutment.

The hexagonal screw hole 20 is inserted in the hexagonal hole 12 to convey or tighten the healing abutment 10.

However, the healing abutment 10 is separated several times until the artificial prosthesis is raised, and the bone fusion state is checked or disinfected. When the artificial prosthesis 10 is loosened and loosened frequently, the hexagonal hole 12 loosens, The healing abutment 10 inserted into the driver 20 is easily removed. Further, the frictional force due to the food waste accumulated in the hexagonal hole 12 is also a factor for the healing abutment 10 to easily fall off from the hexagonal screw driver 20.

In this case, when the healing abutment 10 inserted in the hex driver 20 is released in the patient's mouth, the healing abutment 10 is moved to the stomach through the esophagus, or to the large Accidents can happen.

Therefore, it is best that the healing abutment 10 and the hexa driver 20 can be separated easily once the fastening is completed without falling off the fastening tool until the healing abutment is fastened to the fixture. However, It does not meet the conditions.

In the present specification, terms such as "comprise" or "have" are intended to specify that there are stated features, numbers, steps, operations, elements, parts or combinations thereof, and that one or more other features But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that, in the drawings, the same components are denoted by the same reference symbols as possible. Further, detailed descriptions of known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some of the components in the drawings are exaggerated, omitted, or schematically illustrated.

FIG. 2 illustrates a set of healing abutment mechanisms 1000 including a healing abutment 100 and a hex driver 200 according to the present invention, and with reference to the accompanying drawings, do.

The present design includes a healing abutment 100 and a hexa driver 200 wherein the illustrated arrangement is such that the healing abutment 100 in the hexa driver 200 when the healing abutment 100 is handled Special safety measures are provided to prevent falling.

The healing abutment 100 screwed to the fixture has a truncated cone shape as a whole. At the lower end of the healing abutment 100, there is provided a coupling protrusion 110 formed with a male screw 112 screwed to the fixture, and a hexagonal hole 120 having a hexagonal cross section is formed on the upper surface thereof. This configuration is very similar to the conventional healing abutment 10 of Fig.

The healing abutment 100 of the present invention has a feature in that at least two or more hooking jaws 130 are provided along the edge of the upper surface and the hook driver 200 is provided with a hook And a pair of hook arms 230 for hooking the jaws 130 to hold the healing abutment 100 thereon. The position of the hooking jaw 130 is determined by the surface of the hexagonal hole 120. The position of the hooking jaw 130 is determined by the hooking jaw 130 on a virtual line extending in a direction perpendicular to the midpoints of the two facing surfaces of the hexagonal hole 120, . That is, the hooking jaw 130 faces the surface of the hexagonal hole 120 in a frontal manner.

The post 210 has an hexagonal insert end 220 at its one end and a hexagonal insert end 220 extending from the insert end 220 so as to correspond to two mutually opposing sides of the insert end 220. [ And a pair of elastic hook arms 230 provided on the posts 210 spaced apart from each other. Each hook arm 230 includes an elastic arm 232 having a first width a and a second width b greater than the first width a, And hooks 234. The pair of hook arms 230 can be integrally formed by machining a cylindrical member which is fitted and fixed to the posts 210.

4 and 5, when the insertion end 220 of the hex driver 200 is inserted into the hexagonal hole 120 of the healing abutment 100, the hook of the free end of the hook arm 230 234 are brought into contact with the upper surface of the healing abutment 100, and then are smoothly bent by the elasticity thereof and advanced toward the edge of the healing abutment 100. When the hook 234 passes over the edge, it elastically enters into the hooking jaw 130 opposed to the hooking arm 230 and the hook 234 is caught in the hooking jaw 130, Even if the insertion end 220 of the heel abutment 100 is to be pulled out of the hexagonal hole 120 of the healing abutment 100,

Since the direction in which the hook arm 230 extends and the position of the hooking jaw 130 are aligned with respect to the two opposed faces of the hexagonal hole 120 and the insertion end 220, The hook 233 is automatically hooked on the hooking jaw 130 when the insertion end 220 of the hex driver 200 is pushed into the hexagonal hole 120 by being pushed in the direction toward the hooking jaw 130 .

2, the hooking jaw 130 includes a total of six hooking jaws (not shown) positioned on a virtual line extending in a direction perpendicular to the midpoints of all the facing surfaces of the facing pairs of the hexagonal holes 120 130). This allows the hex driver 200 to be fitted in the hooking jaw 130, which always faces the hook arm 230, even if the hex driver 200 is randomly inserted into the healing abutment 100 without any orientation. If the number of the hooking jaws 130 is set to 6, it is not necessary to align the hooking arm 230 with the direction of the hooking jaw 130 every time it is used. Also, although the figure shows that the hook arms 230 are provided as a pair, it is also possible to provide three pairs of hook arms 230 at equal angles so as to correspond to the six hooking jaws 130.

However, if only the hooking jaw 130 is formed in the healing abutment 100, the hook 233 is removed from the hooking jaw 130 when the hex driver 200 is separated from the healing abutment 100 Additional action is required, which can be inconvenient. Therefore, the present invention provides a special structure that can release the hook 234 from the hooking jaw 130 with only one hand operating the hex driver 200, ).

FIG. 3 is an enlarged view of the hooking jaw 130 and the release groove 140 indicated by "A" in FIG. As shown in the figure, a release groove 140 is provided for releasing the hook arm 230 from the hooking jaw 130 about the hooking jaw 130. The release groove 140 has a width corresponding to the first width a corresponding to the width of the elastic arm 232 and extends from the hooking jaw 130 to the upper surface of the healing abutment 100 in an inclined manner The first ditch 141 and the first ditch 141 are formed to communicate with the lower surface of the first ditch 141 and have a width corresponding to the second width b which is the width of the hook 234, And an extended second groove (142).

In other words, the second ditch 142 having a rectangular cross section having the second width b penetrates from the lower side of the hooking jaw 130 to the upper surface of the healing abutment 100, and the second ditch 142 142 may be seen in a form in which the first trench 141 having a narrower first width a is incised. The concave surface of the hooking jaw 130 is connected to the continuous surface inclined downward along the boundary with the detaching groove 140. [

Figure 5 shows the first position of the hex driver 200 where the hook 234 of the hook arm 230 is hooked on the hooking jaw 130 of the healing abutment 100, The state of the hook arm 230 at the second position in which the hex driver 200 is further pushed in is shown in Fig. 6, when the hex driver 200 is moved to a second position, which is further inserted into the hexagonal hole 120, relative to the first position, the hook 234 of the hook arm 230 is engaged with the hook- 130 to reach the inlet of the second trench 142. [0064]

When the hexa driver 200 is pulled up and separated from the healing abutment 100 in the state of FIG. 6 (second position), the elastic arm 232 is moved along the narrow first groove 141, The hooks 234 move along the second wider trenches 142 to separate and release the hook arms 230 from the healing abutments 100. [

The series of processes shown in FIGS. 4 to 7 is performed by an operation of inserting the hex driver 200 into the hexagonal hole 120. Therefore, the present invention is capable of causing an operation of hooking or releasing the hook 234 to or from the hooking jaw 130 with only one hand of operating the hex driver 200, and the hooking arm 230 has a good bending elasticity The processes of FIGS. 4 to 7 occur smoothly.

On the other hand, it is convenient for the user to grasp the first position of FIG. 5 and the second position of FIG. 6 more easily. To this end, an annular groove 240 may be formed in the post 210 to indicate the depth of insertion of the hex driver 200, which transitions from the first position to the second position. That is, the user grasps the point where the annular groove 240 engraved on the post 210 is aligned with the upper surface of the healing abutment 100 as the first position, Can be grasped as the second position.

Furthermore, it may be inconvenient to visually inspect the insertion depth of the hex driver 200, so that it is possible to grasp the boundary point passing from the first position to the second position through the tactile sense. That is, when the O-ring 242 is inserted into the annular groove 240 of the post 210, the instantaneous resistance when the O-ring 242 slightly protruding from the annular groove 240 enters the insertion hole By sensing the change, it can be noticed that the hex driver 200 has reached the first position.

As described above, the hooking jaws 130 may be provided to correspond to the respective surfaces of the hexagonal hole 120. Of course, six of the hooking jaws 140 may be provided correspondingly.

It will be apparent to those skilled in the art that various modifications and additions, additions, substitutions, and additions may be made to the components without departing from the spirit of the invention as set forth in the appended claims. It will be understood that various modifications and changes may be made thereto without departing from the spirit and scope of the invention.
