The present invention relates to an implant abutment, and more particularly, to form an incision surface and a tool gripping groove on the abutment upper inclined surface to enable fastening with two fastening tools, and transmits a strong fastening force to the alveolar bone during fastening. By allowing a high fastening force with the dental fixture to be implanted, to increase the bonding force with the dental fixture implanted in the alveolar bone, and relates to an implant abutment that prevents deformation of the abutment that occurs during joining.

Implant is a type of prosthesis used to replace a problem or missing tooth, which can be individually performed without damaging adjacent teeth, and has a relatively long life and is one of the latest medical technologies.

Since the implant is implanted after drilling the alveolar bone of the patient using a drill or the like, it is most important to perforate the alveolar bone of the patient.

To replace the missing tooth roots (roots), a artificial tooth called a fixture made of titanium, etc., which is not rejected by the human body is planted in the bone that has fallen out, and then an artificial tooth called crown is implanted. It is a state-of-the-art procedure to restore the function of the teeth by fixing to the artificial root through abutment.

In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and have the same function or shape as natural teeth, but do not cause tooth decay.

Such dental implants are implanted in upper and lower alveolar bones (hereinafter referred to as 'alveolar bones') of damaged teeth, such as the roots of natural teeth, and fixtures supporting artificial crowns, and coupled to this fixture. An abutment, and an artificial crown that is fixed in the oral cavity by the abutment to reproduce the same shape and function as natural teeth.

In this configuration, the fixture is fixed to the alveolar bone to be completely fixed to the alveolar bone like the root of a natural tooth, and then the abutment is connected to the fixture of the implant with an abutment screw, and the artificial crown connection If an artificial crown is attached to the implant, the implant is completed.

However, the implant abutment is formed on the incision surface and the usual hexagonal grooves on the upper side, such hexagonal grooves in the case of repeated coupling with the jig, dismantling and strong bonding force fracture or breakage of the hexagonal grooves There was a problem in that the abutment and loss of movement of the abutment due to abrasion causes inconveniences in coupling or dismantling during the procedure.

It is proposed to solve the problems of the prior art as described above, the object of the present invention is to form a cutting surface and a tool gripping groove on the abutment upper inclined surface to enable fastening with two kinds of fastening tools, strong when fastening Implant abutments to increase the cohesion with the dental fixture implanted in the alveolar bone and to increase the cohesion force and prevent the deformation of the abutment that occurs during engagement To provide advice.

In order to achieve the above technical problem,

In the implant abutment comprising an artificial crown connection part, a soft tissue contact part, and a fixture connection part,

The artificial crown connection part is cut in one side vertically from the upper end to the lower end with a certain thickness and the coupling increasing groove formed in multiple stages at intervals on the outer circumferential surface to facilitate the coupling with the artificial dental crown. It provides an implant abutment, characterized in that consisting of the tool gripping groove is formed in a semi-circular form from the top to the bottom end with a predetermined thickness on the other side of the incision surface.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

1 is a perspective view showing an abutment for an implant according to an embodiment of the present invention, Figure 2 is a side view showing the abutment of FIG. 3 is a plan view illustrating the abutment of FIG. 1, and FIG. 4 is a diagram illustrating A-A of FIG. 3.

Referring to the drawings, the implant abutment 2 is largely composed of an artificial dental connection part 4, a soft tissue contact part 6, and a fixture fastening part 8, thereby increasing the coupling to the artificial dental connection part 4 The groove 4-1, the incision surface 4-2, and the tool holding groove 4-3 are formed further.

The coupling increasing groove 4-1 is formed in multiple stages at intervals on the outer circumferential surface to facilitate coupling with the artificial dental crown (not shown). Coupling groove (4-1) not only generates a solid coupling force when the artificial crown is combined, but also when the height adjustment is required by cutting the balance between the natural teeth and artificial dental can be easily adjusted.

As the coupling augmentation groove 4-1 is formed in multiple stages in the artificial crown connection part 4, the artificial crown connection part 4 has an upper end (a), a middle upper end (b), a middle lower end (c), and a lower end (d). Separated by.

The incision surface (4-2) is formed on one side vertically from the upper middle (b) divided by the coupling increasing groove (4-1) to the lower end (d) with a predetermined thickness. The incision surface (4-2) is formed of a vertical surface (4-21) and a horizontal surface (4-22) to couple the artificial dental connection (4), to facilitate the holding of the tool when dismantling.

The tool gripping groove 4-3 is a groove formed in a semicircular shape from the top to the bottom end with a predetermined thickness on the other side of the incision surface 4-2. The tool gripping groove 4-3 is distinguished from the tool for gripping the cut surface 4-2, and is a groove formed to increase the gripping force by another tool.

Therefore, the abutment 2 can be strongly applied to the fixture to increase the completeness and success rate of the procedure to increase the satisfaction of the patient and the operator.

Referring to the operation of the present invention made as described above, when the abutment (2) is coupled to the female thread groove of the fixture previously treated in the alveolar bone, formed in the artificial crown connection portion 4 of the abutment (2) The tool holding groove 4-3 and the incision surface 4-2 can be used to hold the two kinds of tools shown in the drawings.

When the abutment 2 held by the tool is coupled to the fixture, the abutment 2 is gripped more accurately when using the hexagonal groove formed in the existing abutment.

In other words, the use of the tool gripping groove 4- and the incision surface 4-2, which are deep and long, is eliminated, and the procedure is precisely intended as the intention of the operator, as there is no fear of wear or fracture.

Therefore, when the abutment 2 is operated, precisely the use of the tool is performed during the repeated operation of the operation leading to the dismantling and dismantling of the artificial dental connecting part 4, thereby providing a strong binding force to the abutment 2. It can be delivered.

As described above, the present invention can strongly transmit the force required when the abutment coupled to the fixture is strongly coupled, thereby achieving an accurate and rigid coupling.

The precise combination of the abutment also makes the treatment of the artificial crown coupled to the abutment firm, thereby satisfying both the patient and the operator.

The tool gripping groove and incision surface are formed in the abutment for the use of two kinds of tools, and the wear and damage caused by the joining and disassembling are prevented, thereby increasing the reliability of the product.
