Description

The implant for the operation of transplanting artificial teeth

The present invention relates to an implant used for artificial tooth implantation, and more specifically, to form a plurality of curved recesses in the male thread formed on the body of the abbot-fixture implanted in the jawbone, and the surface of the recessed portion is laser-etched (Etching) relates to an implant for artificial teeth implantation to improve the binding force between the abbot-fixture and the bone of the jaw bone (dense bone, spongy bone).

In general, it supports the teeth in the oral cavity by the squeezed bones and sponges of the jawbone, and when inflammation or flavor occurs on the gums, the support of the dense bones and the sponges that support the teeth weakens, causing the teeth to shake, which causes toothache due to tooth decay Done.

Toothache is a relatively severe pain in the human body, so it is artificial tooth to remove the tooth decay suffered by toothache and to replace the function of the tooth in place.

In order to plant the artificial teeth, the prosthetic implant is coupled between the jawbone and the artificial tooth, and the abut-fixture, which is a component of the implant, is planted in the jawbone, and the abutment-fixture is held in the dense bone and the sponge bone of the jawbone. It is supposed to support it.

As such, an implant has been developed to firmly fix the artificial tooth to the jawbone.

The implant is divided into an abbot-fixture, an abbot-cylinder, and a cylinder screw, and the implant is configured by inserting an abbot-cylinder on the abbot-fixture and fastening a cylinder screw on the upper part. In the fixture, one or two rows of screws are formed on the outer circumference to fix the jawbone.

For example, in the implants of Utility Model Registration Nos. 98-20535 and 99-16876, which have been elected and published from the present application, the UBART fixture, which firmly fixes the artificial tooth to the jawbone, has a cylindrical shape with a male thread. It is composed of or inclined inward to the lower end of the cylindrical, in the case of the former in order to fasten to the dense bone and the cancellous bone is located in the entrance of the bone at the point of fastening than the diameter of the abort-fixture Because of this small size, there is difficulty in trying to open a goal by applying artificial force, and in the latter case, the process of planting the abort-fixture in the goal is made by tapering the lower part of the abit-fixture smaller than the diameter of the body. It is easy to make an incision in the tapered section to form a taper and taper in the fabrication of the abort-fixture. Had a faulty work processes are required to be separately two factors that production costs rise.

In addition, the male thread formed on the outer circumferential surface of the ATV-fixture is composed of one or two rows of screws, so when the ATV-fixture is planted in the bone of the jawbone, one pitch or two pitches are made in one rotation of the ABART-fixture. Since the planting operation is slow because the movement, and the thread of the abbot-fixture is in contact with the screw bone of the bone, there is a problem in that the firmness is somewhat inferior to just contact with each other.

In order to solve this problem, there is an implant for artificial teeth implantation of Utility Model Registration No. 204815, developed and registered by the applicant of the present invention. The weaknesses that are gained but rather weak are found.

The present invention has been made to solve the above-mentioned conventional problems, and improves the bonding force to the bone by etching the indentation and the indentation in the male thread portion of the abut-fixture body of the implant used for implanting artificial teeth. Its purpose is to make it possible.

In order to achieve the above object, in the implant consisting of a combination of the abut-fixture, abut-cylinder, cylinder screw, the implant is inserted into the insertion hole of the jawbone formed on the body of the abut-fixture fixing the artificial teeth It is intended to implement the abort-fixture, which is formed by forming a plurality of curved recesses in the male thread and etching the surface by laser.

The present invention embodied as described above forms a concave indentation to be curved in the male external thread of the abbot-fixture inserted into the bone of the jawbone, and by etching the curved indentation, the indentation is inserted into the indentation part of the bone. Will improve the bond with the goal.

Hereinafter, the configuration of the present invention will be described in detail with reference to the attached drawings of the abort-fixtures of an implant constituted by an embodiment of the present invention.

As shown in FIGS. 1 and 2, the implant 1 according to the present invention has an abut-fixture 10 for supporting an artificial tooth on the jawbone 40 and a middle part inserted into the bottom of the artificial tooth. The ATV-cylinder 20 and the artificial tooth is divided into a cylinder screw 30 that is attached to the ATV-fixture 10 to fix the artificial tooth 10, and consists of a combination thereof.

In the above configuration, the abort-fixture 10, which is the subject of the present invention, is divided into a body 12 and a ranch groove 11, and the body 12 is formed in a cylindrical shape at a lower end portion of which a male screw is formed on an outer circumferential surface thereof. The inclination is given to face inwardly, and one or more concave portions 13 are formed to be curved in the male screw portion, and an etching 14 is performed to etch the surface of the concave portion 13 with a laser. On the other hand, the wrench groove 11 is to form a screw in the inner circumferential wall by digging the recessed groove 31 to a predetermined depth in order to screw the cylinder screw (30).

In addition, the abut-cylinder 20 has a through-hole 21 formed at an upper portion of which the outer circumferential surface is gently inclined as usual, and the cylinder screw 30 has a concave inlet portion so as to attach a tightening screw to the upper portion. 31) was formed to form a screw, and the bottom was formed with a male screw having a predetermined length so that it can be attached to the ranch groove 12 of the abbot-fixture (10).
