KR200424940Y1 - Fixture Driver for a Dentel Implant - Google Patents

Abstract

The present invention relates to a fixture driver for use in implantation of a jawbone by rotating a fixture, which is an artificial tooth, in the procedure of a dental implant. In particular, the head portion 11 of the polygon is attached to the wrench portion 13 of the fixture driver. By forming the fixed grip 12 having elasticity on the outside thereof, the fixture can be connected to the driver effectively without using the mount used to connect the fixture and the driver in the existing procedure. It can be sold out and prevents the fixture from being damaged due to uncoupling between the fixture and the driver.In particular, it does not use a mount that prevents the procedure failure by maintaining a high tightening force when inserting the fixture into the alveolar bone. The present invention relates to a fixture driver for dental implant surgery.

The present invention relates to a surgical driver used to implant a fixture corresponding to an artificial tooth into an alveolar bone in a dental implant procedure for forming an artificial tooth. The present invention relates to a fixture driver for a dental implant procedure that does not use a mount capable of transferring and placing a chew.

The conventional implant placement system is composed of a mount driver 50, a mount screw 40, a mount 30 and a fixture 20 as shown in Figs. In order to transfer and fix the fixture 20 into the oral cavity of the patient, first, as shown in FIG. 2, the mount 30 is positioned on the fixture fixing protrusion 22 located above the fixture, and then the mount screw ( 40) Secure the mount and fixture. Subsequently, after fastening the assembly between the mount driver 50, the fixture 20, the mount 30, and the mount screw 40 on the upper part, the mount driver is mounted on the handpiece and transferred into the oral cavity. Fixture is placed in the alveolar bone of the patient. After the installation is completed, the operator removes the mount driver 50 and then removes the mount screw 40 to separate the mount 30 from the fixture 20.

As described above, the conventional implant placement system combines the fixture and the mount using a mount screw first, and after the placement, the removal of the mount screw has to be performed in the narrow oral cavity of the patient. This is required, and above all, during the screwing process of the mounting screw or in the process of releasing it, the upper part of the fixture is deformed, or the abutment coupling screw thread formed on the inner circumferential surface is damaged, so that parts such as abutment are It creates a serious problem that can not be concluded. From the standpoint of production, there is a problem in that the production cost increases due to the processing of disposable parts such as mounts and mount screws in addition to fixtures.

Therefore, the present invention is designed to solve the problems of the structure of the conventional artificial tooth fixer, and it is possible to operate the fixture by attaching to the handpiece by the driver itself without using a mount configuration, and fixing the fixture. It is an object of the present invention to provide a fixture driver that can be fixedly transported.

The present invention for achieving the above object is provided with a polygonal groove and a fixture fixing protrusion on the top of the fixture, the front end of the fixture driver, the polygon head to transmit the rotational force through the handpiece, the fixture and the correct fastening The guide portion and the fixing grip for holding and circumscribing the circumference of the fixture fixing protrusion are provided to provide a fixation driver for the implant procedure without using the mount.

Hereinafter, the configuration of the fixture driver according to the present invention will be described in detail according to the accompanying drawings.

The present invention has a multi-groove 21 in the front of the inner screw thread hole and a fixture 20 having a polygonal fixture fixing protrusion 22 formed at the top thereof. And a polygonal head 11 fastened to the polygon groove 21 to be in contact with the lower portion thereof to transmit the rotational force applied from the handpiece, and to hold and fix the outer surface of the fixture fixing protrusion 22 around the fixed grip 12. Fixture having a wrench portion (13) consisting of a) consisting of a handpiece fixing part 15 to be fastened to the handpiece and a driver bag (14) for transmitting the rotational force applied from the handpiece to the wrench portion on the opposite side. Drive.

Referring to the operation of the fixture driver of the present invention configured as described above are as follows. Polygonal head (11) is applied to the rotational force applied from the handpiece by inserting the guide portion (10) provided at the tip of the present invention to the polygonal groove (21) up to the polygonal head (11) while inserting the slide into the polygonal groove (21) In order to deliver to the fixture 20 through the multi-groove 21, the circumscribed circle of the multi-fixture fixing projection 22 of the protruding portion of the multi-groove 21 of the top of the fixture 20 is the present invention The fixture 20 is inserted in contact with the inner surface of the fixing grip 12 made of an elastic material of the in-fix driver 100 to fix the fixture 20 so as not to be detached from the fixture driver 100.

The fixture 20 fixed to the tip is seated in a drill hole pre-drilled in the alveolar bone and rotated through the handpiece in such a state that the fixture 20 is rotated and screwed into the alveolar bone.

The present invention constituted as described above has an effect of effectively fixing a fixture without a mount by forming a polygonal head portion in a wrench portion of an implant driver for fixing the implant and forming an elastic fixed grip on the outside thereof, and fixing It is effective to prevent the fixture from being damaged due to non-coupling between the chew and the driver. In particular, it is effective to prevent the procedure failure by maintaining a high tightening force when inserting the fixture into the alveolar bone.

In addition, the cost savings can be expected as the implant-related parts do not have to be produced in one-time mount-related parts.
