Definitions
- the present invention relates to an implant screw, and more particularly, to an implant screw having a groove formed in a thread so that the end of the thread is split in order to increase the fastening force of the screw.
- a screw 5 for the implant is used to couple the abutment to the fixture.
- the fixture is coupled to the alveolar bone, the abutment is inserted into the fixture, and then the screw 5 is inserted into the abutment and screwed into the fixture. The abutment is then fixed to the fixture.
- the screw 5 is thus threaded 6 in order to engage with the fixture.
- the conventional screw (5) is formed in the shape of a general thread (6) as shown in FIG.
- the conventional implant screw 5 has a problem in that the coupling of the threads 6 is not firm and is released from the fixture when the load is steadily received.
- the present invention is to solve the above problems. It is an object of the present invention to provide a screw for an implant in which the thread of the screw is not loosened from the fixture.
- the implant screw according to the present invention which fixes the abutment to the fixture, has a groove formed along the screw thread so that its end is split in the screw thread of the screw.
- the thread of the screw is not formed with the groove at the lower end thereof.
- a groove is formed at the end of the screw thread of the screw and the end is divided.
- the end of the thread elastically deforms and plays the same role as the spring washer. This prevents the screw from loosening easily in the fixture.
- FIG. 1 is a conceptual diagram of an embodiment of a screw for an implant according to the present invention
- FIG. 2 is an application example of the embodiment shown in FIG.
- 3 is a conceptual diagram of a conventional screw.
- FIGS. 1 and 2 An embodiment of a screw for an implant according to the present invention will be described with reference to FIGS. 1 and 2.
- a groove 13 is formed in the thread 11.
- the groove 13 is formed at the end of the thread 11 and is formed along the thread 11.
- the groove 13 is formed along the screw thread 11 from the top of the screw thread 11 to the bottom, it is preferable that it is not formed at the lower end.
- the end of the screw thread 11 is split so that the end thereof is deformed in the direction of the arrow 15.
- the end of the thread 11 serves as a spring washer to prevent the screw 10 from being loosened to the fixture 3.
- the fixture 3 is placed in the alveolar bone, the abutment 1 is inserted into the fixture 3, and then the screw 10 is inserted from the abutment 1 into the fixture 3. To screw the screw 10 into the fixture 3.
- the groove 13 is formed in the thread 11 of the screw 10, when the screw 10 is screwed with the fixture 3, the groove 13 serves as a spring washer and the screw 10 is fixed as a fixture ( It prevents from loosening easily in 3).
- the present invention prevents the abutment 1 from being released from the fixture 3.

Abstract
La présente invention concerne une vis d'implant et, et plus particulièrement, une vis d'implant ayant une rainure formée sur un filet de vis de sorte que l'extrémité du filet de la vis soit divisée afin d'augmenter la force de blocage de la vis. A cet effet, la vis d'implant pour fixer un pilier à un dispositif de fixation, selon la présente invention, comporte une rainure formée le long du filet de vis de sorte que l'extrémité du filet de la vis soit divisée. En outre, dans ce cas, il est préférable que la rainure ne soit pas formée sur la partie d'extrémité inférieure du filet de vis. Dans le cas de la présente invention, la rainure est formée sur l'extrémité du filet de vis de sorte que l'extrémité soit divisée. Ainsi, si la vis est bloquée sur l'élément de fixation, l'extrémité du filet de vis est déformée élastiquement de manière à remplir la même fonction qu'une rondelle à ressort. Par conséquent, la vis ne peut pas être facilement libérée de l'élément de fixation.
