Like the above modification, the size of the tooth rest is made very small, so that there is an advantage of easy handling.

7 is a cross-sectional view showing an implant assembly according to a third embodiment of the present invention.

As shown, the tooth rest 110 and the tooth rest 110 is inserted and consists of a fixture 50 that is fitted to the extraction hole. That is, the fixture 50 and the tooth rest 110 is fitted into the foot hole (134 of Figure 7a) formed in the jaw bone of the patient, the difference butt 112 is exposed and artificial teeth are installed. If necessary, the dental support 112 itself can be manufactured in the form of an artificial tooth so that the implant can be mounted in one operation.

Tooth rest 110 is the head 112, the neck 116 and the screw body 120 is integrally formed in the longitudinal direction.

The head 112 may be formed in a cylinder or polygonal pillar, a compound pillar or ball shape, and may be inclined at a parallel or constant angle with respect to the longitudinal central axis.

The neck 116 is tapered in a hopper shape, and is accommodated in the neck storing portion 56 of the fixed body 50 as described later.

Preferably, a support collar 114 protrudes outward from the neck 116, and more preferably a skirt 114a is bent downward from the support collar 114. Accordingly, the skirt 114a surrounds the neck 116, resulting in a groove 117 consisting of an inner side 115 of the skirt 114a, a back side of the color 114, and a side of the neck 116. do. Preferably, the inner surface of the skirt 114a and the side surface of the neck 116 may be tapered at a predetermined angle so that the groove 117 is widened downward.

The cross-sectional shape of the groove 117 may be trapezoidal, triangular, or arcuate, depending on the shape of the bottom of the groove. That is, when the bottom surface of the groove 117 is a plane, it becomes trapezoidal, and when it is a line, it becomes a triangle, and if it is an arc shape, it becomes an arc-shaped triangle.

The screw body 120 has a cylindrical shape as a whole and has a parabolic cross section with the largest diameter in the middle in the longitudinal direction. Further, optionally, a coupling screw 122 is formed outside the end of the screw body 120, and is used to engage with the fixture 50, as described below.

In addition, the protrusion 120 is formed on the outer surface of the fixing body 120, and preferably, a spiral protrusion extending in the longitudinal direction is formed.

The fixing body 50 has a through hole 58 communicating with both ends therein, except for the neck storing portion 56 formed at an upper portion of the through hole 58, and screws of the tooth rest 110. By having a diameter smaller than the diameter of the middle of the body 120, when the tooth rest 110 is inserted, the fixture 50 is expanded outward.

The side wall of the through hole 58 may be formed with a thread 61 to be coupled to the protrusion 118 of the tooth rest 110.

The neck accommodating part 56 formed on the upper part of the fixture 50 is tapered to receive the hopper-shaped neck 116 in close contact with each other. Accordingly, the cross section of the shoulder 52 surrounding the neck storage portion 56 is composed of the side wall 54, the top surface 55 and the outer side surface 53 of the neck storage portion 56, which is described above. By providing the same cross-sectional shape as the groove 117 of the tooth rest 110 is in close contact with each other.

Preferably, at least one slit 60 is formed on the side wall of the through hole 58, and preferably, the slit 60 extends to an end of the fixture 50 such that the end is formed of a plurality of segments. To be separated. Therefore, when the body 120 is inserted, each of the separated segments are expanded outward to press the side wall of the extraction hole.

In addition, the slit 60 may be formed without extending to the end of the fixing body 50. In this case, a coupling thread 64 is formed on the inner wall of the end of the through hole 58. Thus, since the segments are separated only in the middle but not at the end, the middle portion expands outward and presses the sidewall of the extraction hole.

The outer surface of the fixing body 50 is formed with a projection 62 for pressing the extraction hole, preferably, a spiral projection extending in the longitudinal direction is formed.

A method of mounting an artificial tooth using an implant assembly having such a structure will be described.

Referring to FIG. 7A, after extracting the tooth of the patient, the fixture 50 is inserted into the generated extraction hole 134. At this time, when the projections, particularly the spiral projection 62 is formed on the outer surface of the fixing body 50 is inserted while rotating.

Subsequently, the tooth rest 110 is inserted into the through hole 58 of the fixture 50. As the tooth rest 110 is inserted, each segment separated by the slit 60 is expanded outward while the largest diameter portion of the body 120 passes through the neck storage 56.

When the thread 61 is formed on the sidewall of the through hole 58, the protrusion 118 of the tooth rest 110 is coupled with the coupling thread 61 can be easily and reliably inserted.

When the insertion is completed to the end of the through-hole 58, it is possible to combine the fixture 50 and the tooth rest 110 in two ways. That is, as described above, the coupling thread 61 is formed on the sidewall of the through hole 58 to be coupled to the protrusion 118 of the tooth rest 110 so as not to be separated after mounting. In this case, it is not necessary to form the thread 64 at the end of the through hole 58, and each segment separated by the slit 60 is expanded to press the side wall of the extraction hole 134. On the other hand, the slits 60 do not extend to the ends, so that the threads 64 may be formed at the ends in the state where the ends of the fixture 50 are not separated, and thus may be coupled to the screws 122 of the tooth rest 110. .

When the mounting is completed in this way, the fixed body 50 is expanded by the body 120 of the tooth rest 110 is fixed by pressing the side wall of the extraction hole 134. In particular, the projections 62 formed on the outside of the fixture 50 are not separated by grasping the sidewall of the extraction hole 134.

In addition, as described above, the shoulder 52 of the fixture 50 is in close contact with the groove 117 of the tooth rest 110 to fundamentally prevent saliva from invading the interior of the fixture from the outside.

Referring to FIG. 8, various types of shoulders and grooves closely attached thereto are illustrated.

Referring to FIG. 8A, an arc-shaped groove 117 is formed on the tooth rest, and an upper end of the shoulder 52 closely contacting the tooth rest is formed in an arc shape. In addition, referring to Figure 8b, the trapezoidal groove 117 is formed in the tooth rest, the cross-sectional shape of the shoulder 52 in close contact with this also forms a trapezoid.

8C illustrates a trapezoidal protrusion 111 formed from the collar 114 of the tooth rest, and a groove 59 is formed in close contact with the shoulder 52. In FIG. 8D, the shoulder 52 forms a plane 55 on the upper end of the neck storing unit 56 of the fixture, and the color of the tooth rest forms a flat plane 55 so as to be in close contact with the lower end of the neck storing unit. A 54a is formed and a step 115a is formed in the neck of the tooth rest and is in close contact with each other.

In FIG. 8, the modified examples are expected as examples, but various other modifications are possible, and a configuration in which they are commonly provided is that the neck and the neck storage portion are in close contact with each other in a tapered form at the boundary portion.

9 is a cross-sectional view showing an implant according to a fourth embodiment of the present invention.

The fourth embodiment has a configuration in which the diameter of the body 120 of the tooth rest 110 is constant in the third embodiment, and the profile of the sidewall of the through hole 58 in contact therewith is changed. In other words, the sidewall of the through hole 58 has a parabolic cross section having the largest diameter at a predetermined position, preferably the middle diameter in the longitudinal direction.

In addition, the diameter of the body 120 has a diameter larger than the diameter of the middle of the through hole 58 so that when the body 120 of the tooth rest 110 is inserted, the fixture 50 is expanded outward.

In addition, as in the third embodiment, the coupling thread 61 may be formed on the sidewall of the through hole 58 to engage with the protrusion 118 of the tooth rest 110.

Although the above has been described with reference to the preferred embodiments of the present invention, it is obvious that various changes can be made at the level of those skilled in the art.

For example, the length, width and number of slits formed in the through hole may be appropriately adjusted. Moreover, the cross-sectional profile of the through hole side wall or the screw body may be presented in various ways depending on the size of the extraction hole.

In addition, the implant of the present invention can be used not only as a dental artificial tooth, but also as a fixing anchor (anker) for construction or mechanical devices, and when used as an anchor, the degree of expansion can be precisely adjusted, and in particular, It is possible to seal and block the invasion of foreign substances such as moisture.

It is natural that such changes or modifications fall within the scope of the present invention without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiment, but should be determined by the claims described below.

As described above, the present invention has various advantages.

First, the implant can be mounted simply and immediately in one-stage immediately after extraction. Therefore, the patient can save the time to wait 3 to 6 months until the bone adhesion after implantation, and can reduce the pain by reducing the operation time.

In addition, since the structure is simple, it is easy to manufacture and there is an advantage that can be fixed immediately by a simple operation.

In addition, there is an advantage that it is possible to reliably prevent foreign matter, such as saliva, from entering the tooth rest using the tapered sealing.
