Description

임플란트시술용 인공치아고정체{Fixture for dental implant}Fixation for dental implant

본 발명은 치과용 임플란트에 사용되는 인공치아고정체에 관한 것으로, 더욱 상세하게는 상단에 인공치아를 설치하기 위한 어버트먼트가 장착되는 어버트먼트설치부가 구비되며 외주연에 칩포켓이 형성된 절삭날부와 체결나사부가 구비된 인공치아고정체의 어버트먼트설치부와 체결나사부사이에 체결나사부와 동일한 리드를 가지는 다줄나사로 된 미세체결나사부가 상광하협으로 테이퍼지게 형성되도록 구성되므로써, 치과용 임플란트의 시술시 인공치아고정체가 치조골에 천공형성된 삽입공에 삽입될 경우 치조골의 상부에 단단하게 형성된 부위에 다줄나사로 된 미세체결나사부의 다수의 나사산이 집중적으로 체결되어 더욱 더 견고한 결합상태를 유지할 수 있게 되므로 인공치아고정체의 초기고정력을 대폭 증대시킬 수 있도록 한 것이다.The present invention relates to an artificial tooth fixation body used in a dental implant, more specifically, an abutment installation portion is equipped with an abutment for installing an artificial tooth on the top and a cutting edge portion formed with a chip pocket on the outer periphery. The micro fastening screw part of the multi-threaded screw having the same lead as the fastening screw part is formed between the abutment installation part and the fastening screw part of the artificial tooth fixator provided with the fastening screw part to be tapered to the upper and lower straits, so that the dental implant can be treated. When the artificial tooth fixture is inserted into the insertion hole formed in the alveolar bone, a plurality of threads of the micro fastening screw part of the multi-threaded screw are intensively fastened to the area formed firmly on the upper part of the alveolar bone, thereby maintaining a more firm coupling state. The initial fixation of stagnation can be greatly increased.

일반적으로 치과용 임플란트(implant)란 치아가 상실된 부분에 티타늄재질로 된 나사형상의 인공치아고정체(fixture)를 매식하여 일정기간동안 뼈와 융합되도록 한 후 그 위에 연결부재인 어버트먼트(abutment)를 결합한 다음 인공치아(crown) 등의 보철물을 고정시키므로써 치아기능을 회복시키게 되는 치과시술을 말한다.In general, dental implants are implanted with a screw-shaped artificial tooth fixture made of titanium on the part where the tooth is lost to fuse with the bone for a certain period of time, and then the abutment as a connecting member thereon. By combining the artificial teeth (crown) such as fixing the prosthesis to restore the dental function refers to the dental procedure.

이러한 치과용 임플란트에 사용되는 종래의 인공치아고정체는 도 1에 도시되어 있는 바와 같이 상단에 인공치아를 설치하기 위한 어버트먼트가 장착되는 어버트먼트설치부(2)가 구비되며 외주연에 칩포켓(3a)이 형성된 절삭날부(3)와 체결나사부(4)가 형성되도록 구성되어 있다.Conventional artificial tooth fixture used in such a dental implant is provided with an abutment installation portion (2) equipped with an abutment for installing an artificial tooth on the top as shown in Figure 1 and the chip on the outer periphery It is comprised so that the cutting edge part 3 and the fastening screw part 4 with which the pocket 3a was formed may be formed.

그리고, 종래의 인공치아고정체는 상부에 결합되는 어버트먼트의 종류와 결합방식에 따라 상기 어버트먼트설치부(2)의 형상과 구조가 달라지게 되고, 이에 따라 인터널(internal)방식과 익스터널(external)방식 등으로 나뉘어진다. In addition, in the conventional artificial tooth fixing body, the shape and structure of the abutment mounting part 2 vary according to the type and coupling method of the abutment coupled to the upper part, and accordingly, the internal method and the extension It is divided into tunnel type and the like.

상기와 같이 구성되어 있는 종래의 인공치아고정체는 인공치아를 시술하고자 하는 치조골(턱뼈)(11)에 천공형성된 삽입공에 나사식으로 삽입되어 하단부에 형성된 칩포켓(3a)을 구비한 절삭날부(3)에 의해 치조골(11)에 천공형성된 삽입공의 내주면에 암나사부(12)를 형성시키게 되고, 이와 같이 절삭날부(3)에 의해 형성된 암나사부(12)에 절삭날부(3)의 상부에 연속형성된 체결나사부(4)가 순차적으로 체결되므로써 고정되는 것이다. The conventional artificial tooth fixture is configured as described above is a cutting blade portion having a chip pocket (3a) formed in the lower end by screwed into the insertion hole formed in the alveolar bone (jaw bone) 11 to be treated artificial artificial teeth ( The female threaded portion 12 is formed on the inner circumferential surface of the insertion hole formed in the alveolar bone 11 by 3), and thus the female threaded portion 12 formed by the cutting edge portion 3 is formed on the upper portion of the cutting edge portion 3. Continuously formed fastening screw portion (4) is to be fixed by sequentially tightening.

이와 같이 치조골(11)에 나사식으로 삽입설치된 인공치아고정체(10)가 뼈조직과 완전히 융합되어 견고한 고정상태가 되기 전까지 인공치아고정체(10)와 치조골의 결합상태를 유지시키는 역할을 하는 초기고정력은 인공치아고정체(10)의 체결나사부(4)와 치조골(11)의 하부에 연약하게 형성된 저밀도의 연조직(11b)과의 체결상태보다는 치조골(11)의 상부에 단단하게 형성된 고밀도의 경조직(11a)과의 체결상태에 의해 크게 좌우된다. Thus, the initial fixation force that serves to maintain the combined state of the artificial tooth fixture 10 and the alveolar bone until the artificial tooth fixture 10, which is screwed into the alveolar bone 11, is completely fused with the bone tissue until it is firmly fixed. Is a high density hard tissue 11a formed firmly on the upper surface of the alveolar bone 11 rather than a fastening state of the fastening screw portion 4 of the artificial tooth fixture 10 and the soft tissue 11b of low density formed at the lower part of the alveolar bone 11. It depends a lot on the state of fastening.

그러나, 종래의 인공치아고정체(10)는 도 1에 도시되어 있는 바와 같이 치조골(11)의 경조직(11a)과 체결되고 있는 체결나사부(4)의 나사산수가 2 ~ 3개정도밖에 되지 않을 뿐 아니라, 이 또한 경조직(11a)의 상부에 걸쳐진 상태로 불완전하게 체결되거나 경조직(11a)과 연조직(11b)의 경계부위에 걸쳐진 상태로 불완전하게 체결되어 온전한 체결력을 발휘하지 못하게 되어 실질적으로 경조직(11a)과 안정된 체결상태를 유지하게 되는 체결나사부(4)의 나사산은 1 ~ 2개에 불과하므로, 인공치아고정체(10)의 초기고정력이 현저히 저하되어 치조골(11)과의 골융합이 이루어질 때까지 안정적인 고정상태를 유지하지 못하게 되는 치명적인 문제점이 있었다.However, as shown in FIG. 1, the conventional artificial tooth fixture 10 has only about 2 to 3 threads of the fastening screw portion 4 which is fastened to the hard tissue 11a of the alveolar bone 11. In addition, this is also incompletely fastened in a state spanning the upper portion of the hard tissue (11a) or incompletely fastened in a state spanning the boundary between the hard tissue (11a) and the soft tissue (11b) to exhibit an incomplete tightening force substantially hard tissue (11a) Since only one or two threads of the fastening screw part 4 to maintain a stable fastening state are secured, the initial fixation force of the artificial tooth fixing body 10 is remarkably lowered until stable fusion with the alveolar bone 11 is achieved. There was a fatal problem that prevented them from maintaining state.

상기 문제점을 해결하기 위하여 본 발명은 상단에 인공치아를 설치하기 위한 어버트먼트가 장착되는 어버트먼트설치부가 구비되며 외주연에 칩포켓이 형성된 절삭날부와 체결나사부가 구비된 인공치아고정체의 어버트먼트설치부와 체결나사부사이에 체결나사부와 동일한 리드를 가지는 다줄나사로 된 미세체결나사부가 상광하협으로 테이퍼지게 형성되도록 구성되므로써, 치과용 임플란트의 시술시 인공치아고정체가 치조골에 천공형성된 삽입공에 삽입될 경우 치조골의 상부에 단단하게 형성된 부위에 다줄나사로 된 미세체결나사부의 다수의 나사산이 집중적으로 체결되어 더욱 더 견고한 결합상태를 유지할 수 있게 되므로 인공치아고정체의 초기고정력을 대폭 증대시킬 수 있도록 하는 것을 기술적 과제로 한다.In order to solve the above problems, the present invention is provided with an abutment mounting portion which is equipped with an abutment for installing an artificial tooth on the top, and a tooth of an artificial tooth fixing body having a cutting edge and a fastening screw portion having a chip pocket formed on an outer circumference thereof. The micro fastening screw part of the multi-threaded screw having the same lead as the fastening screw part is formed between the butt installment part and the fastening screw part to be tapered to the upper and lower straits, so that the dental implant is inserted into the alveolar bone during the procedure of the dental implant. When inserted, a plurality of threads of the micro fastening screw portion of the multi-threaded screw are concentrated on the portion formed on the upper part of the alveolar bone so as to maintain a more firm coupling state, thereby greatly increasing the initial fixation force of the artificial tooth fixator. Let it be technical problem.

상기 기술적 과제를 달성하기 위하여 본 발명은 상단에 인공치아를 설치하기 위한 어버트먼트가 장착되는 어버트먼트설치부가 구비되며 외주연에 칩포켓이 형성된 절삭날부와 체결나사부가 구비된 것에 있어서, 상기 어버트먼트설치부와 체결나사부사이에는 체결나사부의 리드와 동일한 리드를 가지는 다줄나사로 된 미세체결나사부가 상광하협으로 테이퍼지게 형성되어 있는 것을 특징으로 한다. In order to achieve the above technical problem, the present invention is provided with an abutment installation part is mounted on the abutment for installing an artificial tooth on the top and provided with a cutting edge and a fastening screw portion formed with a chip pocket on the outer periphery, The abutment installation portion and the fastening screw portion are characterized in that the micro fastening screw portion of the multi-threaded screw having the same lead as the lead of the fastening screw portion is tapered to the upper and lower straits.

이하, 상기 목적을 달성하기 위하여 본 발명을 도 2 내지 도 5를 참고하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 5 to achieve the above object.

도 2는 본 발명에 의한 인공치아고정체의 구성을 나타내는 측면도이며, 도 3의 (가)(나)는 본 발명에 의한 인공치아고정체의 다른 실시예를 나타내는 측면도이고, 도 4는 본 발명에 의한 인공치아고정체의 설치상태를 나타내는 측단면도이며, 도 5는 도 4에 도시된 A부의 확대도이다. Figure 2 is a side view showing the configuration of the artificial tooth fixing according to the present invention, Figure 3 (a) (b) is a side view showing another embodiment of the artificial tooth fixing according to the present invention, Figure 4 according to the present invention Fig. 5 is a side sectional view showing the installation state of the artificial tooth fixing body, and Fig. 5 is an enlarged view of the portion A shown in Fig. 4.

본 발명에 의한 인공치아고정체는 도 2에 도시되어 있는 바와 같이 상단에 인공치아를 설치하기 위한 어버트먼트가 장착되는 어버트먼트설치부(2)가 구비되며 외주연에 칩포켓(3a)이 형성된 절삭날부(3)와 체결나사부(4)가 구비된 공지의 인공치아고정체의 어버트먼트설치부(2)와 체결나사부(4)사이에 체결나사부(4)의 리드 (lead : 나사를 1회전시켰을 때 축방향으로 움직이는 거리)와 동일한 리드를 가지는 다줄나사(1리드내에 여러개의 나사산이 형성되는 나사)로 된 미세체결나사부(5)가 상광하협으로 테이퍼지게 형성되도록 구성되어 있는 것을 특징으로 한다.As shown in FIG. 2, the artificial tooth fixing body according to the present invention is provided with an abutment installation part 2 on which an abutment for installing an artificial tooth is mounted on an upper end thereof. A lead of the fastening screw part 4 is inserted between the abutment mounting part 2 and the fastening screw part 4 of a known artificial tooth fixing body having the cutting edge part 3 and the fastening screw part 4 formed therein. It is characterized in that the micro fastening screw portion 5 made of multi-threaded screws (screws having a plurality of threads formed in one lead) having the same lead when rotated in the axial direction is formed to be tapered to the upper and lower straits. do.

그리고, 상기 미세체결나사부(5)는 체결나사부(4)와 동일하게 형성되는 1리드내에 가능한 한 많은 나사산이 형성되도록 하는 것이 체결속도와 체결력의 증대에 유리하게 되는데, 한정된 1리드내에 너무 많은 나사산이 형성되도록 하면 제조시 가공이 어려워지게 될 뿐 아니라 나사산자체의 강도가 떨어져 온전한 체결상태를 유지할 수 없게 되므로 체결나사부(4)의 리드치수에 따라 적정한 수의 나사산이 형성되도록 하는 것이 바람직하다. In addition, the micro fastening screw portion 5 is formed so that as many threads as possible in a lead formed in the same way as the fastening screw portion 4, it is advantageous to increase the fastening speed and fastening force, too many threads within a limited one lead If it is formed, not only the processing becomes difficult during manufacturing, but also the strength of the thread itself is lowered, so that it is not possible to maintain an intact tightening state.

예를 들어, 상기 체결나사부(4)의 리드치수가 0.8mm일 경우 미세체결나사부 (5)는 이 리드내에 피치가 0.2mm인 나사산이 2개 형성되는 2줄나사나 피치가 0.4mm인 나사산이 4개 형성되는 4줄나사나 피치가 0.1mm인 나사산이 8개 형성되는 8줄나사로 형성되도록 하는 것이 가능하지만, 이 때 미세체결나사부(5)는 2줄나사보다 체결속도와 체결력이 우수할 뿐 아니라 8줄나사보다 가공이 용이하며 나사산자체의 강도가 우수한 4줄나사로 형성되도록 하는 것이 바람직하다.For example, when the lead dimension of the fastening screw part 4 is 0.8 mm, the micro fastening screw part 5 is a two-threaded thread in which two threads of 0.2 mm pitch are formed in this lead or a thread of 0.4 mm pitch. It is possible to form four four-threaded screws or eight-threaded screws with a pitch of 0.1 mm, but at this time, the micro-tightening screw portion 5 has only superior fastening speed and fastening force than two-threaded screws. However, it is preferable to form a four-row screw that is easier to process than the eight-row screw and the strength of the thread itself is excellent.

또한, 본 발명에 의한 인공치아고정체의 특징부인 상광하협으로 형성된 미세체결나사부(5)의 구성은 도 2에 도시되어 있는 바와 같은 어버트먼트설치부(2)가 구비된 인터널(internal)방식의 인공치아고정체뿐 아니라, 도 3의 (가)에 도시되어 있는 바와 같은 어버트먼트설치부(2)가 구비된 익스터널(external)방식의 인공치아고정체와 도 3의 (나)에 도시되어 있는 바와 같은 어버트먼트설치부(2)가 구비된 픽싱(fixing)방식의 인공치아고정체에도 형성시킬 수가 있다. In addition, the configuration of the micro fastening screw portion 5 formed by the upper and lower strait, which is a feature of the artificial tooth fixing body according to the present invention, is an internal method provided with the abutment mounting portion 2 as shown in FIG. In addition to the artificial tooth fixture of Fig. 3 (a) of the external (external) artificial tooth fixture provided with an abutment installation portion 2 as shown in (a) of Fig. 3 (b) It is also possible to form a fixative artificial tooth fixation body provided with the abutment mounting portion 2 as shown.
