본 발명은, 나사고정형의 장점을 살리고, 구조와 제조가 간단할 뿐만 아니라, 풀림을 완전히 방지시켜 장기간 흔들림이 없이 치아를 사용할 수 있는 견고한 구조의 치아용 임플란트에 관한 것이다.The present invention relates to a dental implant of a rigid structure that can take advantage of the screw type, not only easy to structure and manufacture, but also to prevent the loosening completely to use the tooth without long-term shaking.

종래의 치아용 임플란트에는, 접착형과 나사고정형이 있으며, 나사형 임플란트는, 잇몸 고정부재인 지대주(픽스처)에 인공 치아를 나사로 고정시키는 것이고, 접착형 임플란트는, 지대주(픽스처)에 인공 치아를 접합제로 접합시키는 것이다. 접착형의 경우 구조가 간단하다는 장점이 있으나, 한번 접합시킨 후에 필요에 따라 분리시키는 것이 나사고정형에 비해 매우 어렵다는 문제가 있다.Conventional dental implants include an adhesive type and a screw fixation type. A screw type implant is a screw for fixing an artificial tooth to an abutment (fixture) which is a gum fixing member, and an adhesive type implant is used to fix an artificial tooth on abutment (fixture). It joins with a bonding agent. In the case of the adhesive type, there is an advantage that the structure is simple, but there is a problem that it is very difficult compared to the screw-mounted type after the bonding once separated.

따라서, 이러한 나사의 풀림을 저감시키거나 방지시키기 위해 다양하게 개발이 이루어지고 있으나, 여전히 완전한 풀림의 방지를 해결하지는 못하고 있다. 나사풀림의 원인으로는 부정확한 금속구조물의 적합, 부정교합, 이 악물기나 알치증 과 같은 비기능력, 과도하게 연장된 캔틸레버에 의한 과하중, 단일 수복치에 가해진 비트는 힘, 고정나사의 불량한 적합 등에 기인한 것으로 알려져 있다.Therefore, various developments have been made to reduce or prevent such loosening of screws, but still do not solve the prevention of complete loosening. Causes of screw loosening include incorrect fit of metal structures, misalignment, aggravation such as gutter or alkalosis, overload by an overly extended cantilever, twisting force applied to a single restoration, and poor fit of a set screw. It is known that it originates from etc.

따라서, 본 발명은, 이러한 문제를 해결하기 위한 것으로, 나사고정형의 장점을 살리고, 구조와 제조가 간단할 뿐만 아니라, 풀림을 완전히 방지시켜 장기간 흔들림이 없이 치아를 사용할 수 있는 견고한 구조의 치아용 임플란트를 제공하는 데에 그 목적이 있다.Accordingly, the present invention is to solve this problem, taking advantage of the screw fixing type, not only the structure and manufacturing is simple, but also prevents loosening completely to use the tooth without long-term shaking for a long-term dental implant The purpose is to provide.

이러한 목적을 달성하기 위해 본 발명의 일실시예에 따른 치아용 임플란트는, 잇몸에 매립되어 잇몸에 고정되는 잇몸 고정부재와, 외주에 치아가 고정되고 상기 잇몸 고정부재에 대해 체결볼트를 개재하여 고정되며 체결볼트의 숫나사부가 관통되는 관통공이 구비되고 체결볼트의 헤드부가 걸려 안착되는 헤드부 수용부가 중심축을 따라 형성된 치아고정부재를 포함하여 구성되는 치아용 임플란트에 있어서, 상기 체결볼트의 숫나사부에 체결되어 통상의 체결력에 대응하는 해제력만으로는 풀림이 저지되도록 하측 중앙부에 변형절개부가 형성되고 그 변형절개부의 외측에 형성된 정상나사부의 일부가 상대적으로 변형된 변형나사부가 정상나사부의 외측에 형성된 풀림저지너트를 포함하며, 상기 치아고정부재의 하단에는 회전방지돌출부가 형성되고, 그 회전방지돌출부와 상기 풀림저지너트가 삽입되어 회전이 방지되는 회전방지홈부가 상기 잇몸 고정부재의 중심축상에 상부에 형성되며, 그 회전방지홈부의 하부에는 풀림저지너트가 체결볼트에 체결된 후, 더욱 치아고정부재와 잇몸 고정부재를 체결하도록 고정암나사부가 형성된 것을 특징으로 한다.

In FIG. 3, the deformation cutout portion 21 is formed from the center to the inside of the lower surface of the loosening jersey nut 20, and one side or both sides of the deformation cutout portion 21 are shown in a solid line from the state shown by the double-dot chain line. By deforming at a portion of the top screw portion 22 to form a relatively modified deformation screw portion 23. As shown in FIG. 4, by forming the deformation screw portion 23, the tightening torque is increased by the amount of elastic deformation in which the deformation screw portion 23 is restored to the solid line state from the state of the double-stranded chain when the fastening bolt 40 is fastened. Thus, once locked, the loosening is strongly inhibited.

또, 도 5에는, 풀림저지너트(20')는, 그 측벽에 변형절개부(21)를 구비하며, 그 변형절개부(21)의 하부를 X방향으로 상향하여 각도(a)만큼 변형시킴으로써 정상나사부(22)에 대해 변형나사부(23)가 형성되게 된다. 이와 같은 구성에 있어서는 도 6에서 체결볼트(40)를 체결하는 때에 변형나사부(23)에서 탄성변형량(-a)만큼 -X방향으로 복원시켜 체결되게 되므로, 탄성변형에 따라 체결토크가 증대되게 되고, 일단 체결된 뒤에는 통상의 해제력만으로는 체결볼트(40)가 풀리지 아니하게 되어 풀림이 강력하게 저지된다.In Fig. 5, the loosening jersey nut 20 'includes a strain cut portion 21 on its side wall, and the bottom of the strain cut portion 21 is deformed by an angle a upward in the X direction. The deformation screw portion 23 is formed with respect to the top screw portion 22. In such a configuration, when the fastening bolt 40 is fastened in FIG. 6, the tightening torque is increased by restoring in the -X direction by the amount of elastic deformation (-a) in the deformation screw part 23, and thus the tightening torque is increased according to the elastic deformation. , Once fastened, the fastening bolt 40 is not released only by the normal release force, and the loosening is strongly inhibited.
