There is an advantage that it can.

In addition, the integrated implant according to the present invention has the advantage that the inner cap is made of a synthetic resin material does not apply excessive force in the oral cavity of the patient compared to the conventional O-ring insert of the integrated implant.

In addition, the integrated implant according to the present invention has the advantage that the inner cap and the protrusion is coupled to each other by the locking method is easy to be attached and detached, and thus the procedure is easy and can be easily remounted once the cap is removed. .

In addition, the integrated implant according to the present invention has the advantage that the length of the central support portion is shorter than the length of the wall portion has no problem that the locking jaw formed at the bottom of the wall portion is not caught by the locking groove of the protrusion by the insertion of the central support portion. .

In addition, since the integral implant according to the present invention is formed with a salivary gland hole in the protrusion, even if the saliva is stuck in the coupling groove during the procedure, the standing saliva can escape to the outside through the salivary gland hole. This has the advantage of less breeding.

Although the preferred embodiment of the present invention has been described above, the present invention may be modified as follows.

First, in the above-described embodiment, the gingival level portion has a circular cross section, but is described to have a cylindrical or cylindrical shape that is constantly maintained along one axis, but the present invention is not limited thereto. It is also possible to have the shape of a truncated cone having a circular cross section 151 but gradually increasing in diameter from the lower end toward the upper side. As such, when the gingiva level portion 151 has the shape of a truncated cone, the period during which the gum is healed is reduced.

In addition, in the above-described embodiment, the gingiva level portion 151 is formed in the form of a cylinder or a cylinder, but as shown in FIG. 10, the outer surface of the gingiva level portion 151 is formed in a polygonal cross-sectional shape. It can also be formed. That is, it is also possible to be made into the form which the predetermined torque application driver can engage.

The semiconductor package of the present invention described above is not limited thereto, and the scope of rights may be extended as long as it can be interpreted by the claims.
