본 발명은 스크루가 내장된 임플란트 연결기둥에 관한 것으로서, 보다 상세하게는 인공치근에 맞물려 체결되는 연결기둥 내부에 스크루가 삽입된 상태로 고정링에 의해 이탈이 방지되도록 구속됨에 따라 임플란트를 시술하는 중에 스크루의 분실이 방지됨과 아울러 시술시간이 크게 단축되고, 특히 연결기둥을 인공치근에서 분리시 스크루가 고정링에 구속되어 정지된 상태로 회전되면서 인공치근을 밀어내므로 연결기둥이 쉽게 분리되는 스크루가 내장된 임플란트 연결기둥의 체결구조에 관한 것이다.The present invention relates to an implant connection column with a screw embedded, and more particularly, while the implant is constrained to be prevented from being detached by a fixing ring in a state where a screw is inserted into the connection column engaged with the artificial tooth. In addition to preventing the loss of the screw, the procedure time is greatly shortened. Especially, when the connecting column is detached from the artificial tooth root, the screw is constrained to the fixing ring and is rotated in a stationary state to push the artificial tooth root. It relates to the fastening structure of the embedded implant connecting column.

통상적으로 임플란트는 상실된 치아의 치근을 대신할 수 있도록, 인체에 거부반응이 없는 재질(예컨대, 티타늄 등)로 만든 인공치근을 이가 빠져나간 치조골에 심어서 유착시킨 뒤 연결기둥과 함께 인공치아를 고정시켜 치아의 원래 기능을 회복하도록 하는 첨단시술이다.In general, implants are implanted in the alveolar bone where the tooth is displaced, and the artificial tooth is made of non-rejection material (eg titanium) to replace the root of the missing tooth. It is a cutting-edge procedure to restore the original function of the teeth.

종래에 임플란트 시술은 먼저 이가 빠져나간 치조골에 유착되는 인공치근과, 인공치근의 일단이 수용되어 각부에 맞물려 회동이 방지되는 연결기둥과, 연결기둥 내부에 수용되어 인공치근과 나사결합되는 스크루와, 연결기둥의 선단에 결속되는 인공치아를 정해진 순서대로 시술한다.Conventionally, the implant procedure is an artificial tooth root that is first adhered to the alveolar bone from which the tooth is pulled out, one end of the artificial tooth tooth is accommodated in each connection to prevent rotation, a screw accommodated inside the connecting column and screwed into the artificial tooth, The artificial teeth that are bound to the tip of the connecting column are treated in the prescribed order.

여기서, 인공치아를 지지하는 연결기둥은 인공치근에 수용되는 부분에 경사면이 형성되어 인공치근에 긴밀하게 맞물린 상태로 스크루에 의해 나사결합되어 결속됨에 따라 인공치아를 교환해야 할 경우 인공치근에 나사결합된 스크루를 분리하더라도 서로 긴밀하게 맞물린 경사면이 쉽게 분리되지 않아 연결기둥을 분리하는데 상당한 시간이 소요되어 시술시간이 지연되는 단점이 따랐다.Here, the connecting column for supporting the artificial tooth is formed with an inclined surface formed in the part accommodated in the artificial tooth and screwed to the artificial tooth when the artificial tooth needs to be exchanged as it is screwed together by a screw in a state of being closely engaged with the artificial tooth. Even if the screws were separated, the inclined surfaces closely interlocked with each other could not be easily separated, and thus, a considerable time was required to separate the connection columns, which delayed the procedure time.

뿐만 아니라, 쉽게 분리되지 않는 연결기둥은 집게와 같은 공구를 사용하여 잡아당기는 방식으로 분리하므로 자칫 잘못하면 이가 빠져나간 치아와 주변 치아에까지 충격이 전해져 추가적인 치아손상을 초래하는 폐단이 따랐다.In addition, the disconnection column is not easily separated by pulling using a tool such as a forceps, so if a mistake is made, a shock is transmitted to the teeth and the surrounding teeth, which leads to additional tooth damage.

또한, 임플란트 시술중에 연결기둥을 인공치근에 결속하기 위한 스크루를 일일이 연결기둥에 삽입한 다음 체결해야 하는 번거로운 단점과 함께 연결기둥을 분리시 스크루가 이탈되어 분실될 우려가 상당히 큰 실정이다. In addition, during the implant procedure, there is a significant risk that the screw is detached and lost when the coupling column is removed, with the cumbersome disadvantage of having to insert and then fasten a screw for fastening the coupling column to the artificial tooth.

이에 따라 본 발명은 상기한 점에 착안하여 안출한 것으로서, 보다 상세하게는 인공치근에 맞물려 체결되는 연결기둥 내부에 스크루가 삽입된 상태로 고정링에 의해 이탈이 방지되도록 구속됨에 따라 임플란트를 시술하는 중에 스크루의 분실이 방지됨과 아울러 시술시간이 크게 단축되고, 특히 연결기둥을 인공치근에서 분리시 스크루가 고정링에 구속되어 정지된 상태로 회전되면서 인공치근을 밀어내므로 연결기둥이 쉽게 분리되는 스크루가 내장된 임플란트 연결기둥의 체결구조를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been conceived in view of the above point, more specifically to implant the implant as it is constrained to be prevented from being separated by the fixing ring in the state that the screw is inserted into the connection column to be engaged with the artificial tooth root. The screw is prevented from being lost and the procedure time is greatly shortened. Especially, when the connecting column is detached from the artificial tooth root, the screw is constrained by the fixing ring and is rotated in a stationary state to push the artificial tooth root. The purpose is to provide a fastening structure of the implant connection pillar is embedded.
