외주는, 다각(polygon)부(31)에는 돌출부(302)가 형성되고, 이어 오목한 그루브(306)가 형성되고, 이어 씰 안착부(32)가 형성되고, The outer periphery is formed with a protrusion 302 in the polygonal portion 31, and then a concave groove 306 is formed, and then a seal seating portion 32 is formed.

상기 그루브(306)에는 원주 3등분 되어 중심 방향으로 형성된 홀(hole)이 다각부(31)의 각 모서리(301)와 일치되어 위치하고, 다각부 각 모서리(301)의 측단부(30)에서, 원주 3등분 되어 홀(39)까지 관통되는 절개부(38)가 형성된다.In the groove 306, holes formed in the circumferential third portion are formed to coincide with each corner 301 of the polygonal portion 31, and at the side end portion 30 of each corner 301 of the polygonal portion, An incision 38 is formed in three parts of the circumference and penetrates to the hole 39.

어버트먼트의 다각부에 형성된 돌출부는, 가로(D)로 놓인 직사각형이 점진적으로 작아지며 돌출된 형태로 각 각면부(303)에 일정 길이(H) 간격으로 2개소씩 형성되고,The protrusions formed on the polygonal portion of the abutment are each formed at two intervals at predetermined lengths (H) on each of the surface portions 303 in a shape in which the rectangles placed in the horizontal (D) are gradually smaller and protruded.

압입나사(도 2)는 어버트먼트의 내주(inside of cylinder)에 삽입되어 상기 어버트먼트의 확장부(307)를 확장하고, 경사부(305)에 일치 압착되는 구조로써, 일측의 측단부(20)로부터 외측으로 점진적으로 커지는 경사부(21)가 형성되고, 선행 경사부와 다른 각도로 점진적으로 커지는 경사부(22)가 연장되고, 이어 나사부(24)가 형성된다.The press-fit screw (FIG. 2) is inserted into the inner circumference of the abutment to expand the extension portion 307 of the abutment and is pressed against the inclined portion 305. An inclined portion 21 that gradually increases outward from the 20 is formed, and an inclined portion 22 that gradually increases at an angle different from the preceding inclined portion extends, and then a threaded portion 24 is formed.

이측(26)은 어버터먼트의 크라운결합부의 일부를 보완하는 형태로 형성되며, 측단부에는 체결을 위해 렌치가 삽입되는 렌치자리(28)가 형성된다.This side 26 is formed in a form that complements a portion of the crown coupling portion of the abutment, the side end is formed with a wrench seat 28 is inserted into the wrench for fastening.

삼각실링(도 4)은, 내주는 관통(42)되고, 외주는 점진적으로 커지는 경사부(41)가 형성되고, 재질은 인체용 실리콘이 된다.In the triangular seal (FIG. 4), the inner circumference penetrates through 42, and the outer circumference forms a gradually increasing inclined portion 41, and the material is made of human silicone.

어버트먼트의 삼각실링 자리(32)와, 픽스쳐의 경사부(60) 사이에 압착되어 실질적인 밀폐 기능을 한다.It is compressed between the triangular sealing seat 32 of the abutment and the inclined portion 60 of the fixture to function substantially as a seal.

텐션링(도 5)은, 내주는 상기 어버트먼트의 그루브(306)에 일치되는 양 측단이 관통되는 볼록원호(51)가 형성되고, 외주는 점진적으로 커지는 상기 픽스쳐의 경사부(60)와 일치되는 점진적으로 커지는 경사부(52)가 형성되고, 높이(H) 방향으로 양측단이 관통된 일정 넓이의 절개부(53)가 형성된다.The tension ring (FIG. 5) is formed with a convex arc 51 penetrating both ends of the inner circumference corresponding to the groove 306 of the abutment, and the outer circumference with the inclined portion 60 of the fixture that gradually increases. An inclined portion 52 which is gradually enlarged to coincide is formed, and a cut portion 53 having a predetermined width through which both ends penetrate in the height H direction is formed.

픽스쳐(도 6)는, 다각부의 각 각면부에 어버트먼트의 돌출부와 맞물리는 그루브부가 브이(V)자형으로 원주 선삭된 형태로 일정 길이(H) 간격으로 2개소씩 형성된다.In the fixture (FIG. 6), the grooves engaging with the protrusions of the abutments are formed at two intervals at predetermined intervals H in the form of circumferential turning in a V-shape.

그루브커터(도 7)는, 외주 일측의 일단은 육각상자 형태로, 각 모서리에 브이(V)자형의 커터(78)가 커터면이 중심과 평행을 이루는 형태(79)로 일정길이(H) 간격으로 2개소씩 위치하고,Groove cutter (Fig. 7), one end of the outer peripheral side in the form of a hexagonal box, the V-shaped cutter 78 at each corner is a constant length (H) in the form (79) in parallel with the center of the cutter surface 2 places at intervals,

이단은 점진적으로 커지는 형태의 경사부(77)가 형성되고,The second stage is formed with an inclined portion 77 of the form that gradually increases,

삼단은 원기둥 형태의 바(72)가 위치하고, 이측은 그랩부(71)가 위치한다.The three-stage columnar bar 72 is located, the rear side grab portion 71 is located.

나사 부러짐 등의 문제가 되는 기존 시술된 픽스쳐의 다각부 각면부(68)에 그루브(67)가 존재하지 않을 경우 치조골에 고정된 픽스쳐에 삽입해 수잡업으로 그루브를 형성하게 된다.If the groove 67 is not present in the polygonal face of the polygonal portion 68 of the existing surgical fixture, which is a problem such as screw broken, it is inserted into the fixture fixed to the alveolar bone to form a groove by hand.

커터의 회전직경(76)을 각각 차등화한 2개 이상이 한조가 되어 원활한 그루브 생성을 가능하게 한다. Two or more of the cutters, each of which the diameter of rotation 76 is differentiated, become a set to enable smooth groove generation.
