Description

Implant screw stopper {ANTI-SCREWLOOSENING COVER FOR IMPLANT}

The present invention relates to an anti-loosening stopper of an implant, more specifically

To prevent loosening the fastening screws that join the fixture and abutment to each other

An anti-loosening stopper of an implant inserted into and fixed in the inner hollow of the abutment.

 Tooth implant technology that embeds artificial teeth into alveolar bone when permanent teeth are damaged

It is widely used. Such implants are alveolar bone as shown in FIGS. 1 and 2

An abutment 30 coupled to the fixture 10 through the fastening screw 20, the fastening screw 20, and exposed to the outside, and an artificial tooth 40 fixed to the abutment 30. It is composed of

Referring to the conventional implant with reference to Figure 2, the alveolar bone

The implanted fixture 10 has a screw groove 11 formed to a predetermined depth therein, and the abutment 30 has a hollow shape inside and a seating protrusion 31 31 protrudes to the inner surface at the bottom thereof. Therefore, when the fastening screw 20 is inserted into the internal hollow of the abutment 30, the fastening nut 20 has its head portion 21 seated on the seating protrusion 31 of the abutment and the bolt portion

It protrudes to the lower side of the abutment 30. In this state, when the bolt part of the fastening screw 20 is inserted into the screw groove 11 of the fixture 10, the fixture 10 is connected via the fastening screw 20. And abutment 30 is to be combined with each other. Here, the head portion 21 of the fastening screw is formed with a square groove such as, for example, a hexagonal groove so as to be coupled to the square lens.

However, such conventional implants can be used continuously if artificial teeth are used.

The fastening screw 20 is loosened from the fixture 10. Thus, tightening screw (20)

Is loosened from the fixture 10, the fastening force between the abutment 30 and the fixture 10 becomes weak and the artificial teeth

After shaking, you need to replace it with a new implant or remove the abutment (30)

Problem that requires follow-up procedure that requires tightening screw again firmly in fixture

There was a point.

By filling the hollow of the implant abutment, it protects the fastening screw of the implant and prevents the loosening of the implant screw, so there is no side effect after the implant procedure and there is no need to replace or repair the implant. The satisfaction level is expected to be widely used in dental implants.

Hereinafter, with reference to the accompanying drawings will be described in detail the anti-loosening stopper of the implant according to the present invention.

3 is an overall perspective view of the implant anti-loosening stopper according to the present invention, Figure 4 is a cross-sectional view showing an example in which the implant anti-loosening stopper according to the present invention is inserted into the abutment hollow, Figure 5 Sectional views showing examples of various protrusions and grooves formed on the upper surface of the implant anti-loosening stopper according to the present invention.

Referring to the drawings, the anti-loosening screw 100 according to the present invention includes a body 110 and a rectangular projection (111).

The body 110 is formed in a circular cylinder shape is inserted into the abutment 30 inside the hollow. In addition, the bottom surface of the body 110 is formed with a rectangular projection 111 that is inserted into the angular groove of the head portion 21 of the fastening screw 20 for fastening the fixture 10 and the abutment 30, The square protrusion 111 serves to prevent the fastening screw 20 from rotating.

In addition, the upper surface of the body 110 is a polygon, a circle, a polygonal cylinder, a circular cylinder, a wavy pattern, a polygonal pyramid, a cone, a polygonal cone, a spiral, an animal shape, a person shape, an object shape projection or groove, or Combined form of protrusions and grooves, or rough surfaces,

Protrusions, grooves, or the combination of the protrusions and grooves, or the rough surface of the upper surface of the body is fixed to the protrusions 41 or grooves of the prosthesis 40 to fix the body 110, the lower surface of the body 110 The square projection 111 is an implant screw anti-loosening stopper which prevents the fastening screw from rotating by preventing the fastening screw from rotating.

Furthermore, in order to make the body 110 adhere to the abutment hollows of various sizes, a ring formed of a rubber band or plastic, metal, ceramic, etc., which can increase the size of the side of the body, may be worn.

In addition, the side of the body 110 is preferably coated with an adhesive 130 to attach the body 110 and the abutment 30 to each other, as shown in Figure 4, because of the adhesive This is because the bodies and the abutments can be mounted more firmly by attaching the bodies to each other while pressing the abutments.

2 is a cross-sectional view of a conventional implant,

3 is an overall perspective view of the implant anti-loosening stopper,
