상기 치아 보철물의 제작 과정에서는 어뷰트먼트(5)를 임플란트 아날로그(9)와 분리하거나 결합하는 과정을 반복하게 된다. 임플란트 아날로그(9)와 어뷰트먼트(5)는 나사 결합된 상태이므로 이들을 분리하거나 결합시키는 작업은 용이하지 않으며, 스크류 드라이버와 같은 공구의 조작을 필요로 한다. 심지어, 어뷰트먼트 레벨 임플란트 아날로그는 어뷰트먼트가 아날로그에 이미 한몸으로 고정되어 있어 석고 모델상의 좁은 공간내 어뷰트먼트 아날로그 상에서 보철물을 제작하여야 한다. 따라서 작업이 곤란하고, 시간이 소요되며 작업자의 피로도가 증가되는 단점이 있다. 또한 어뷰트먼트 상에서 변형되기 쉬운 왁스(WAX) 패턴 등을 여러번 탈부착시켜 사용함으로써 최종 보철물의 정확도를 감소시키는 단점이 있다.In the manufacturing process of the tooth prosthesis, the process of separating or combining the abutment 5 with the implant analog 9 is repeated. Since the implant analog 9 and the abutment 5 are screwed together, the work of separating or joining them is not easy and requires the manipulation of a tool such as a screw driver. Even the abutment level implant analog requires that the abutment is already anchored to the analog, making the prosthesis on the abutment analog in tight spaces on the gypsum model. Therefore, the work is difficult, takes time and has the disadvantage of increasing the fatigue of the operator. In addition, there is a disadvantage in that the accuracy of the final prosthesis is reduced by using a detachable wax (WAX) pattern, etc., which are easily deformed on the abutment.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 치아 보철물의 구성을 용이하게 하기 위하여 석고 또는 에폭시 모델에 대하여 자유롭게 고정 또는 분리될 수 있는 임플란트 아날로그를 제공하는 것이다. The present invention has been made to solve the above problems of the prior art, an object of the present invention to provide an implant analog that can be freely fixed or detached with respect to the plaster or epoxy model in order to facilitate the construction of the dental prosthesis. will be.

이하, 본 발명에 따른 임플란트 아날로그의 작용에 대하여 설명하기로 한다. Hereinafter, the operation of the implant analog according to the present invention will be described.
도 2 에 도시된 것은 본 발명의 일례에 따른 임플란트 아날로그의 개략적인 사시도이다.2 is a schematic perspective view of an implant analog according to an example of the present invention.
도면을 참조하면, 임플란트 아날로그는 금속 재료로 형성되는 아날로그 부분(20) 및, 상기 아날로그 부분(20)을 분리 가능하게 수용하고 금속 혹은 플라스틱 재료로 형성되는 하우징 슬리이브(30)를 구비한다. 아날로그 부분(20)은 도면에 도시된 바와 같이 헤드(21), 동체(22) 및 다리부(23)를 구비한다. 상기 헤드(21), 동체(22) 및 다리부(23)는 길이 방향으로 위에서 아래로 연장된다. Referring to the drawings, the implant analog has an analog portion 20 formed of a metallic material and a housing sleeve 30 detachably accommodating the analog portion 20 and formed of a metal or plastic material. The analog portion 20 has a head 21, a body 22 and a leg 23 as shown in the figure. The head 21, the body 22 and the leg 23 extend from top to bottom in the longitudinal direction.
상기 헤드(21)는 임플란트 고정부 헤드 부분을 복제 하는 경우와 어뷰트먼트를 복제하는 경우가 있을 수 있고, 경우에 따라 다양하게 바뀔 수 있다. 예를 들면, 익스터널 헥스(external hex), 인터널 헥스(internal hex), 인터널 라운드(internal round)또는 옥타(octa) 연결방식 등이 있을 수 있고, 임플란트 생산자의 연결구조에 맞추면 되기 때문에 특별히 제한되지 않는다. The head 21 may have a case of replicating an implant fixing head portion and a case of replicating an abutment, and may vary in some cases. For example, there may be an external hex, an internal hex, an internal round, or an octa connection, and may be adapted to the connection structure of the implant producer. It is not limited.
헤드(21)의 상부에는 너트(27)가 고정되고, 헤드(21)와 동체(22) 사이에는 원주를 따라서 원주홈(24)이 형성된다. 동체(22)는 동체(22) 상단부의 직경보다 동체(22) 하단부의 직경이 작아지도록 전체적으로 아래 방향으로 테이퍼진다. 동체(22)의 내부에는 나사 구멍(26)이 형성되고, 동체(22) 내부에 형성된 상기 나사 구멍(26)은 너트(27)에 형성된 나사와 연장된다. 즉, 너트(27)를 통해 나사 결합되는 고정 나사(미도시) 등은 동체(22) 내부의 나사 구멍(26)과도 결합될 수 있다. A nut 27 is fixed to the upper portion of the head 21, and a circumferential groove 24 is formed along the circumference between the head 21 and the body 22. The body 22 is tapered downward as a whole so that the diameter of the lower part of the body 22 becomes smaller than the diameter of the upper part of the body 22. A screw hole 26 is formed in the body 22, and the screw hole 26 formed in the body 22 extends with a screw formed in the nut 27. That is, fixing screws (not shown), etc., which are screwed through the nut 27, may also be coupled to the screw holes 26 inside the body 22.
동체(22)의 하부에 연장되는 다리부(23)는 전체적으로 원통형으로 형성되며, 외측면에 노취(notch, 25)가 형성되어 있다. 상기 노취(25)는 도 2 에서 오직 하나만이 도시되어 있으나, 다리부(23)의 원통 형상에서 직경 방향으로 반대편에 대칭적으로 2 개가 형성되어 있다. 다른 실시예에서는 하나 또는 2 개 이상의 노취부가 형성될 수 있다. Leg portion 23 extending to the lower portion of the body 22 is formed in a cylindrical shape as a whole, the notch (25) is formed on the outer surface. Although only one notch 25 is shown in FIG. 2, two notches 25 are symmetrically formed on the opposite side in the radial direction from the cylindrical shape of the leg 23. In other embodiments, one or more notches may be formed.
하우징 슬리이브(30)는 내부의 일부에 중공형 공간이 형성되며, 하우징 슬리이브(30)의 내측 중공형 공간에는 아날로그 부분(20)이 A 로 표시된 바와 같이 수용된다. 하우징 슬리이브(30)의 상단부는 개방되고, 개방된 상단부에서 원주를 따라 중공형 공간의 내측으로 돌출된 형태를 가지는 립(31)이 형성된다. 하우징 슬리이브(30)는 예를 들어 금속 및 플라스틱 재료로 형성됨으로써, 외력이 가해지면 립(31)이 변형될 수 있다. 외력이 가해질 때 립(31)의 변형을 용이하게 하고 립(31)이 파손되는 것을 방지할 수 있도록 립(31) 사이에는 립 제거부(31a)가 형성되는 것이 바람직스럽다. The housing sleeve 30 has a hollow space formed in a portion thereof, and the analog portion 20 is accommodated in the inner hollow space of the housing sleeve 30 as indicated by A. An upper end of the housing sleeve 30 is opened, and a lip 31 having a shape protruding inwardly of the hollow space along the circumference is formed at the open upper end. The housing sleeve 30 is formed of, for example, metal and plastic material, so that the lip 31 may be deformed when an external force is applied. It is preferable that a lip removal portion 31a is formed between the lips 31 so as to facilitate deformation of the lips 31 and prevent the lips 31 from being broken when an external force is applied.
상기 아날로그 부분(20)이 하우징 슬리이브(30)의 내부에 수용되었을 때, 하우징 슬리이브(30)의 립(31)은 아날로그 부분(20)에 형성된 원주홈(24)에 대응하도록 하우징 슬리이브(30)의 내부 중공형 공간의 크기가 정해진다. 한편, 하우징 슬리이브(30)의 외측 표면에는 두께 감소부(31,33)가 형성된다. 두께 감소부(31,33)는 하우징 슬리이브(30)가 석고 모델(미도시) 안에 고정될 때 석고 모델과의 결합력을 증가시키도록 형성되는 것으로서, 하우징 슬리이브(30)의 외표면 일부에서 두께를 부분적으로 제거함으로써 형성된 것이다. 도면에 도시되지 않은 다른 예에서, 하우징 슬리이브의 외표면 일부를 제거하는 대신에, 엠보싱을 형성할 수 있다. When the analog portion 20 is received inside the housing sleeve 30, the lip 31 of the housing sleeve 30 corresponds to the circumferential groove 24 formed in the analog portion 20 so as to correspond to the housing sleeve. The size of the interior hollow space of 30 is determined. Meanwhile, thickness reducing parts 31 and 33 are formed on the outer surface of the housing sleeve 30. The thickness reducing parts 31 and 33 are formed to increase the bonding force with the gypsum model when the housing sleeve 30 is fixed in the gypsum model (not shown), and at a part of the outer surface of the housing sleeve 30. It is formed by partially removing the thickness. In another example not shown in the figures, instead of removing a portion of the outer surface of the housing sleeve, embossing may be formed.
도 3 에는 하우징 슬리이브(30)의 일부를 절개한 상태로 도시한 사시도가 도시되어 있다. 3 is a perspective view showing a portion of the housing sleeve 30 in a cutaway state.
도면을 참조하면, 하우징 슬리이브(30)의 내부는 중공형으로 형성된 상부(30a) 및 속이 채워진 하부(30b)를 구비한다. 속이 채워진 하부(30b)에는 공구 삽입공(36)이 형성되어 있으며, 공구 삽입공(36)의 상단은 중공형의 상부(30a)에 개방되어 있고, 공구 삽입공(36)의 하단은 외부로 개방되어 있다. 하우징 슬리이브(30)의 중공형 내부에는 인덱스(35)가 형성된다. 상기 인덱스(35)는 도 2 에 도시된 아날로그 부분(20)의 노취(25)에 대응하는 형상을 가진다. 즉, 도 2 에 도시된 아날로그 부분(20)이 하우징 슬리이브(30) 안에 수용되었을 때, 아날로그 부분(20)의 노취(25)에 인덱스(35)가 대응되어 그 안에 안착된다. 따라서 아날로그 부분(20)의 노취(25)와 하우징 슬리이브(30)의 인덱스(35)가 서로 대응되지 않을 경우에는 아날로그 부분(20)이 하우징 슬리이브(30) 안으로 수용될 수 없다. 도면에 도시된 예에서는 오직 하나의 인덱스(35)가 도시되어 있으나, 아날로그 부분(2)의 노취(25)에 대응될 수 있도록, 중공형 상부(30a)의 직경 방향으로 반대편에 대칭적으로 다른 인덱스가 형성된다. 하부(30b)에 형성된 공구 삽입공(36)은 외부로부터 공구를 삽입하여 아날로그 부분(20)을 위로 밀어내기 위한 것이다. Referring to the drawings, the interior of the housing sleeve 30 has a hollow upper portion (30a) and a stuffed lower portion (30b). A tool insertion hole 36 is formed in the lower portion 30b filled with the inside, and an upper end of the tool insertion hole 36 is open to the upper portion 30a of the hollow shape, and a lower end of the tool insertion hole 36 is moved outward. It is open. An index 35 is formed in the hollow interior of the housing sleeve 30. The index 35 has a shape corresponding to the notch 25 of the analog portion 20 shown in FIG. 2. That is, when the analog part 20 shown in FIG. 2 is accommodated in the housing sleeve 30, the index 35 corresponds to the notch 25 of the analog part 20 and rests therein. Therefore, when the notch 25 of the analog portion 20 and the index 35 of the housing sleeve 30 do not correspond to each other, the analog portion 20 may not be accommodated into the housing sleeve 30. In the example shown in the figure only one index 35 is shown, but symmetrically different from the opposite side in the radial direction of the hollow upper part 30a so as to correspond to the notch 25 of the analog part 2. The index is formed. The tool insertion hole 36 formed in the lower portion 30b is for pushing the analog portion 20 upward by inserting a tool from the outside.
도 4 에는 아날로그 부분(20)이 하우징 슬리이브(30)에 결합된 상태로 도시한 단면도가 도시되어 있다. 4 is a cross-sectional view showing the analog portion 20 coupled to the housing sleeve 30.
도면을 참조하면, 나사 구멍(26)이 아날로그 부분(20)의 동체(22) 안으로 연장되는 것이 도시되어 있다. 상기 나사 구멍(26)에 고정 나사(미도시)가 삽입 고정될 수 있다. 하우징 슬리이브(30)에 형성된 립(31)은 아날로그 부분(20)의 원주홈(24)에 삽입되어 있다. 따라서, 외력이 가해지지 않은 상태에서 아날로그 부분(20)은 하우징 슬리이브(30)의 내부에 안정적으로 유지될 수 있다. Referring to the figure, it is shown that the screw hole 26 extends into the body 22 of the analog portion 20. A fixing screw (not shown) may be inserted into and fixed to the screw hole 26. The lip 31 formed in the housing sleeve 30 is inserted into the circumferential groove 24 of the analog portion 20. Therefore, the analog part 20 can be stably maintained inside the housing sleeve 30 in the state where no external force is applied.
위에서 언급된 바와 같이, 하우징 슬리이브(30)의 하부에 형성된 공구 삽입공(36)은 아날로그 부분(20)을 하우징 슬리이브(30)로부터 분리할 때 공구(미도시)를 삽입하기 위한 것이다. 즉, 공구(미도시)를 공구 삽입공(36)을 통해 삽입하여, 아날로그 부분(20)의 저부면을 밀어서 아날로그 부분(20)을 하우징 슬리이브(30)로부터 밖으로 이탈시킬 수 있다. As mentioned above, the tool insertion hole 36 formed in the lower portion of the housing sleeve 30 is for inserting a tool (not shown) when separating the analog portion 20 from the housing sleeve 30. That is, by inserting a tool (not shown) through the tool insertion hole 36, the bottom surface of the analog portion 20 may be pushed out to separate the analog portion 20 from the housing sleeve 30.
한편, 도 5 에 도시된 것은 도 4 에 도시된 B-B 선을 따른 단면도이다. 도면에서 알 수 있는 바로서, 아날로그 부분(20)의 다리부(23)가 하우징 슬리이브(30)의 내부 중공형 공간 안에 수용될 때, 아날로그 부분(20)의 노취(25) 내에 하우징 슬리이브(30)의 인덱스(35)가 대응되는 것을 이해할 수 있다. 5 is a cross-sectional view along the line B-B shown in FIG. 4. As can be seen in the figure, when the leg 23 of the analogue portion 20 is received in the internal hollow space of the housing sleeve 30, the housing sleeve in the notch 25 of the analogue portion 20. It can be understood that the index 35 of 30 corresponds.
도 6 에 도시된 것은 본 발명에 따른 임플란트 아날로그가 석고 모델 안에 매립된 상태를 개략적으로 도시하는 단면도이다. 6 is a cross-sectional view schematically showing a state in which an implant analog according to the present invention is embedded in a gypsum model.
도면을 참조하면, 석고 모델(51)에는 정상적인 치아를 나타내는 석고 치아(55)가 형성되어 있고, 3 개의 임플란트 아날로그가 석고 모델(51) 내에 매립되어 있다. 도면 번호 52 로 표시된 것은 연조직 모델(soft tissue model)이다. 실제에 있어서 구강 안에서 임플란트 고정부의 헤드 높이가 상이하기 때문에, 석고 모델에 매립된 임플란트 아날로그의 헤드가 위치되는 높이도 상이하다. 즉, 도 6 에 도시된 바와 같이, 각각의 임플란트 아날로그가 상이한 높이에 배치된다. 이때 아날로그 부분(20)을 하우징 슬리이브(30)로부터 분리시키기 위해서는 하우징 슬리이브(30)의 저면에 형성된 공구 삽입공(36, 도 4)을 통해 공구(미도시)를 하우징 슬리이브(30) 안으로 밀어 넣어야 하므로, 하우징 슬리이브(3)의 저면은 석고 모델(51)로부터 외부로 노출되어야 한다. 따라서, 석고 모델(51)의 성형시에 석고 모델의 저부 표면이 도면 번호 51a 로 표시된 부분에 있다면, 하우징 슬리이브(30)의 저부가 노출되도록 도면 번호 51b 로 표시된 부분까지 트리밍(trimming)을 수행한다. Referring to the drawings, the plaster model 51 is formed with a gypsum tooth 55 representing normal teeth, and three implant analogs are embedded in the gypsum model 51. Designated by reference numeral 52 is a soft tissue model. In practice, since the head height of the implant fixture in the oral cavity is different, the height at which the head of the implant analog embedded in the gypsum model is located is also different. That is, as shown in FIG. 6, each implant analog is placed at a different height. In this case, in order to separate the analog portion 20 from the housing sleeve 30, a tool (not shown) is inserted into the housing sleeve 30 through a tool insertion hole 36 (FIG. 4) formed in the bottom surface of the housing sleeve 30. Since it must be pushed in, the bottom of the housing sleeve 3 must be exposed outward from the gypsum model 51. Therefore, if the bottom surface of the gypsum model is at the portion indicated by reference numeral 51a at the time of molding the gypsum model 51, trimming is performed to the portion indicated by reference numeral 51b so that the bottom of the housing sleeve 30 is exposed. .
한편, 하우징 슬리이브(30)는 길이가 상대적으로 짧은 단축형 및 길이가 상대적으로 긴 신장형이 구비될 수 있다. 이는 위에서 설명된 바와 같이 구강 내에서 임플란트 고정부의 헤드가 상이한 높이로 배치되기 때문에, 그에 적합한 임플란트 아날로그를 선택하여 사용하기 위한 것이다. 도 6 에 도시된 바를 참조하면, 좌측에 배치된 2 개의 단축형 임플란트 아날로그이고, 우측에 배치된 1 개의 임플란트 아날로그는 신장형 임플란트 아날로그이다. 좌측에 배치된 2 개의 단축형 임플란트 아날로그의 경우는 아날로그 부분의 헤드(21, 도 2)가 낮은 위치에 배치되므로, 상대적으로 길이가 짧은 단축형 임플란트 아날로그를 이용해도 하우징 슬리이브(30)의 저면이 석고 모델(51)의 트림 라인(51b) 아래로 노출될 수 있다. 그러나 우측에 배치된 1 개의 신장형 임플란트 아날로그의 경우에는 아날로그 부분의 헤드(21, 도 2)가 높은 위치에 배치되므로, 상대적으로 길이가 긴 신장형 임플란트 아날로그를 이용하여야만 하우징 슬리이브(30)의 저면이 석고 모델(51)의 트림 라인(51b) 아래로 노출될 수 있다. On the other hand, the housing sleeve 30 may be provided with a short axis of relatively short length and elongation of a relatively long length. This is for selecting and using an implant analog suitable for the head of the implant fixture in different positions in the oral cavity as described above. Referring to FIG. 6, two single-axis implant analogs disposed on the left side and one implant analog placed on the right side are extended implant analogs. In the case of two single-sided implant analogs arranged on the left side, the head 21 (FIG. 2) of the analog portion is disposed at a low position, so that even if a short-length implant analog having a relatively short length is used, the bottom surface of the housing sleeve 30 is plastered. It may be exposed below the trim line 51b of the model 51. However, in the case of one elongated implant analog disposed on the right side, the head 21 (FIG. 2) of the analog portion is disposed at a high position. Therefore, only the relatively long elongated implant analog is used in the housing sleeve 30. The bottom may be exposed below the trim line 51b of the gypsum model 51.
본 발명에 따른 임플란트 아날로그는 도 2 에 도시된 바와 같이 아날로그 부분(20) 및 하우징 슬리이브(30)로 구성되어 제공된다. 본 발명에 따른 임플란트 아날로그는 도 1(a) 내지 도 1(e)를 참조하여 설명된 과정을 통하여 석고 모델 안에 매립된다. 즉, 도 1(c)에 도시된 통상적인 임플란트 아날로그(9) 대신에, 본 발명에 따라서 아날로그 부분(20) 및 하우징 슬리이브(30)를 구비한 임플란트 아날로그가 도 1(e)에 도시된 바와 같이 석고 모델(10) 안에 매립되는 것이 이해될 수 있다. 또한, 3 개의 임플란트 아날로그가 적용되는 경우는 도 6 에 도시된 바와 같이 각각의 임플란트 아날로그가 석고 모델(51) 안에 상이한 높이에 배치된 상태로 매립될 수 있다.The implant analog according to the present invention is provided consisting of an analog portion 20 and a housing sleeve 30 as shown in FIG. 2. The implant analog according to the present invention is embedded in the gypsum model through the process described with reference to FIGS. 1 (a) to 1 (e). That is, instead of the conventional implant analog 9 shown in Fig. 1 (c), an implant analog with an analog portion 20 and a housing sleeve 30 according to the invention is shown in Fig. 1 (e). It may be understood that the embedding in the gypsum model 10 as such. In addition, when three implant analogs are applied, each of the implant analogs may be embedded in the gypsum model 51 at different heights, as shown in FIG. 6.
임플란트 아날로그가 석고 모델(51) 안에 매립된 상태에서 아날로그 부분(20)에 형성된 나사 구멍(26)에 어뷰트먼트(5, 도 1(f))를 나사 고정하여 보철물을 어뷰트먼트(5)의 둘레에서 제작할 수 있다. 이러한 보철물의 제작시에, 어뷰트먼트(5)를 석고 모델(51)로부터 분리하여 가공할 필요성이 반복적으로 발생된다. 이때 종래 기술에서는 어뷰트먼트(5)를 임플란트 아날로그(9)로부터 제거하였으나, 본 발명에서는 어뷰트먼트와 나사 결합된 아날로그 부분(20)을 하우징 슬리이브(30)로부터 분리하는 방식으로 어뷰트먼트를 석고 모델(51)로부터 분리할 수 있다. 즉, 하우징 슬리이브(30)의 저부에 형성된 공구 삽입공(36)을 통해 공구를 삽입하여 아날로그 부분(20)을 위로 밀어냄으로써, 어뷰트먼트가 결합되어 있는 아날로그 부분(20)을 석고 모델(51)로부터 분리시킬 수 있다. 보철물의 제작이 완료되면 도 1(g)를 참조하여 설명된 바와 같이 보철물이 구비된 어뷰트먼트와 아날로그 부분(20)을 분리하고, 어뷰트먼트를 구강 내의 임플란트 고정부에 나사 고정한다.In the state where the implant analog is embedded in the gypsum model 51, the abutment 5 (FIG. 1 (f)) is screwed into the screw hole 26 formed in the analog portion 20, and the prosthesis is abutted (5). It can be produced around. In the production of such a prosthesis, the necessity of repeatedly removing and processing the abutment 5 from the gypsum model 51 is generated. Although the abutment 5 is removed from the implant analog 9 in the prior art, in the present invention, the abutment is detached from the housing sleeve 30 by detaching the analog portion 20 screwed with the abutment from the housing sleeve 30. Can be separated from the gypsum model 51. That is, by inserting the tool through the tool insertion hole 36 formed at the bottom of the housing sleeve 30 and pushing the analog portion 20 upward, the analog portion 20 to which the abutment is coupled is plaster model ( 51). When the production of the prosthesis is completed, as described with reference to FIG. 1 (g), the abutment and the analog part 20 provided with the prosthesis are separated, and the abutment is screwed to the implant fixing part in the oral cavity.
본 발명에 따른 임플란트 아날로그에서는 하우징 슬리이브로부터 아날로그 부분을 간단한 방식으로 분리하거나 또는 하우징 슬리이브에 대하여 간단한 방식으로 아날로그 부분을 고정할 수 있다. 따라서 치아 보철물 구성시에 어뷰트먼트와 결합되어 있는 아날로그 부분을 하우징 슬리이브로부터 분리함으로써 아날로그 부분이 간단하게 석고 모델로부터 분리될 수 있고, 따라서 치아 보철물의 구성을 용이하게 수행할 수 있다.In the implant analog according to the invention it is possible to separate the analog part from the housing sleeve in a simple manner or to fix the analog part in a simple manner with respect to the housing sleeve. Therefore, by separating the analog portion coupled with the abutment from the housing sleeve in the construction of the dental prosthesis, the analog portion can be easily separated from the gypsum model, thus making it easy to construct the dental prosthesis.
