Abstract

The present invention relates to an implant for artificial teeth and, more specifically, to an implant for artificial teeth capable of preventing foreign matter such as mucus-like body fluids from entering into a gap of a coupling part of a fixture (10) and an abutment (20). According to the implant for artificial teeth of the present invention, when the abutment (20) is fastened to the fixture (10) by coupling the abutment (20) to the fixture (10) and tightening a securing screw (40), an abutment surface (23) of the abutment (20) comes into close contact with an abutment support surface (17) of the fixture (10) to seal the gap. A sealing ring (30) fitted to a sealing ring supporter (25) of the abutment (20) is pressed between a bottom (12a) of an abutment engaging hole (12) of the fixture (10) and a lower surface (24a) of a fixture engaging part (24) to prevent foreign matter from entering into the gap between the fixture and the abutment.

Description

이물질 침입을 방지한 인공치아용 임플란트{Dental implant capable of blocking liquid inflow}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an implantable implantable blocking liquid inflow

본 발명은 치아 임플란트에 관한 것으로, 특히 픽스츄어와 어버트먼트의 결합부의 틈새 사이로 침 또는 체액 등과 같은 점액상의 이물질이 침투하는 것을 방지할 수 있게 된 인공치아용 임플란트에 관한 것이다. The present invention relates to a dental implant, and more particularly to an implant for an artificial tooth which is capable of preventing foreign matter such as a needle or body fluid from penetrating into a gap between a fixture and an abutment.

인공치아용 임플란트는 통상 턱뼈에 삽입되어 고정되는 픽스츄어, 픽스츄어에 결합되는 어버트먼트, 상기 어버트먼트를 픽스츄어에 고정해주는 체결나사, 및 상기 어버트먼트의 상부에 결합되는 인공치아로 이루어진다. An implant for an artificial tooth generally includes a fixture inserted and fixed in the jaw, an abutment coupled to the fixture, a fastening screw for fastening the abutment to the fixture, and an artificial tooth coupled to the upper portion of the abutment. .

이러한 종래 인공치아 임플란트는, 상기 구성 부품들이 가공에 의해 제작되므로, 각 구성부품들의 최종 완성품들마다 가공공차 만큼의 치수 편차를 가진다. 이러한 치수 편차를 가진 구성부품들로 구성된 임플란트를 환자에게 시술하고나면, 상기 부품들이 상호 결합되는 결합부에서 상기 가공공차만큼의 틈새가 발생하고, 이 틈새를 통하여 이물질이 지속적으로 침투하여 틈새내에서 부패하여 악취를 발생시키는 문제가 있었다. 또한 구성 부품들의 틈새안으로 침투한 이물질에는 세균이 증식하여 그에 따른 치주염 등 질병을 야기하는 문제가 있었다.Such conventional artificial tooth implants have dimensional deviations as the machining tolerances for the final finished products of the respective constituent parts because the constituent parts are manufactured by processing. When the implant is composed of the components having such dimensional deviations, a gap as much as the machining allowance is generated in the joint portion where the components are mutually coupled, and foreign matter is continuously penetrated through the gap, And there was a problem of generating odor due to decay. In addition, there is a problem that foreign substances that penetrate into the gaps of component parts multiply bacteria and cause diseases such as periodontitis.

이와 같이, 임플란트를 환자에게 시술한 후, 상기한 바와 같은 이물질 침투의 문제가 발생하면 시술된 임플란트를 분해 해체하고나서 재시술하지 않고서는 상기한 문제를 해결할 수 없으므로, 현재 임플란트 구성 부품들의 틈새 사이로 이물질이 침투하는 것을 방지하는 일이 중요한 기술적 과제로 대두되고 있다. As described above, if a problem of foreign matter penetration as described above occurs after the implant is applied to a patient, since the above-described problem can not be solved without disassembling the implanted implant and re-performing the implantation, Preventing foreign matter from penetrating is becoming an important technical challenge.

그럼에도 현재까지 만족할 만한 개발품이 나오지 못하고 있는 실정이다. Nevertheless, there are no satisfactory developments to date.
