Description

어버트먼트 제거 드릴 및 이를 구비하는 어버트먼트 제거 장치Abutment removal drill and abutment removal device having the same
본 발명은, 어버트먼트 제거 드릴 및 이를 구비하는 어버트먼트 제거 장치에 관한 것으로서, 보다 상세하게는, 어버트먼트의 파절시 픽스츄어에 결합되어 있는 어버트먼트의 잔존부분을 용이하게 제거할 수 있는 어버트먼트 제거 드릴 및 이를 구비하는 어버트먼트 제거 장치에 관한 것이다. The present invention relates to an abutment removal drill and an abutment removal device having the same, and more particularly, to easily remove the remaining portion of the abutment coupled to the fixture at the time of fracture of the abutment. It relates to an abutment removal drill capable of and an abutment removal device having the same.
일반적으로 임플란트는 인체조직이 상실되었을 때 회복시켜 주는 대치물을 의미하지만 치과에서는 인공으로 만든 치아를 이식하는 것을 말하는 것으로, 이가 빠져나간 치조골에 상실된 치근(뿌리)을 대신할 수 있는 대체 치근을 심은 뒤 인공치아를 고정시켜 치아의 기능을 회복하도록 하는 시술이다.In general, an implant is a substitute that recovers when tissue is lost, but in the dentist, an implanted artificial tooth is implanted. After implanting an alternative root root to replace the lost root (root) in the alveolar bone from which the tooth is drained Fix the artificial teeth to restore the function of the teeth.
일반 보철물이나 틀니의 경우 시간이 지나면 주위 치아와 뼈가 상하지만 임플란트는 주변 치아조직을 상하지 않게 하며, 자연 치아와 기능이나 모양이 같으면서도 충치가 생기지 않으므로 반영구적으로 사용할 수 있는 장점이 있다.In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they do not have tooth decay even though they have the same function or shape as natural teeth.
또한 임플란트는 단일 결손치 수복은 물론이거니와 부분 무치아 및 완전 무치아 환자에게 의치의 기능을 증진시키고 치아 보철 수복의 심미적인 면을 개선시킬 수 있으며, 나아가 주위의 지지골 조직에 가해지는 과도한 응력을 분산시킴은 물론 치열의 안정화에 도움을 준다. Implants can also enhance the function of dentures and improve the aesthetic aspects of dental prosthetic restorations, as well as single missing tooth restorations, and also dissipate excessive stress on surrounding supportive tissue Sikkim also helps stabilize the teeth.
이와 같이 치과에서 행하는 임플란트 시술은 잇몸뼈, 즉 치조골에 픽스츄어를 식립하는 수술과정과, 식립된 픽스츄어에 어버트먼트를 연결하여 인공치아를 장착하는 보철과정으로 구분된다.The implant procedure performed in the dentistry is divided into a surgical process of placing a fixture on the gum bone, that is, the alveolar bone, and a prosthetic process of mounting an artificial tooth by connecting the abutment to the implanted fixture.
그런데 임플란트의 사용중 외력에 의해 픽스츄어에 결합되어 있는 어버트먼트가 파절되어 버리는 경우가 발생될 수 있으며, 이때 일반적으로 어버트먼트가 픽스츄어에 억지끼움 방식으로 결합되어 있기 때문에 픽스츄어에 결합되어 있는 어버트먼트의 파절 후 잔존부분을 제거하는 것이 용이하지 않다는 문제점이 있다.By the way, the abutment coupled to the fixture may be broken by the external force during the use of the implant.In this case, the abutment is coupled to the fixture because it is generally coupled to the fixture.

이들 도면에 도시된 바와 같이, 본 발명의 제1실시예에 따른 어버트먼트 제거 드릴(100)은, 어버트먼트(Abutment, 400)를 제거하는 드릴비트유닛(200)과, 드릴비트유닛(200)에 형성되며 드릴링시 발생되는 절삭칩을 배출하는 배출부(300)를 포함한다.As shown in these figures, the abutment removal drill 100 according to the first embodiment of the present invention, the drill bit unit 200 for removing the abutment (400), and the drill bit unit ( It is formed on the 200 and includes a discharge portion 300 for discharging the cutting chip generated during drilling.
전술한 바와 같이, 임플란트는 인공으로 만든 치아를 치과에서 이식하는 것으로 치아가 빠져나간 치조골에 상실된 치근(뿌리)을 대신할 수 있는 대체 치근을 심은 뒤, 인공치아를 고정시켜 치아의 기능을 회복하도록 하는 시술을 의미할 수 있지만, 인체조직이 상실되었을 때 회복시켜 주는 대치물을 의미하기도 한다.As described above, the implant is a dental implant implanted in the dental implant to replace the missing root (root) in the alveolar bone is missing, and then implant the artificial tooth to fix the artificial tooth to restore the function of the tooth This can mean a procedure, but it can also mean a substitute to recover when human tissue is lost.
일반적으로 임플란트의 시술법은 다양한 방식이 고려될 수 있는데, 그 중 일 예에 대하여 간략하게 설명하면 다음과 같다. In general, a variety of methods can be considered for the implantation method, which will be briefly described as follows.
우선, 치조골에 드릴링(drilling) 및 탭핑(tapping) 과정을 거쳐 픽스츄어(Fixture, 500) 치수에 부합하는 홈을 형성하고, 치조골에 픽스츄어(500)를 식립하게 된다.First, grooves corresponding to the dimensions of the fixture 500 are formed by drilling and tapping the alveolar bone and implanting the fixture 500 in the alveolar bone.
다음으로, 보철물 제작을 위해 임프레션 코핑을 픽스츄어(500) 상부에 체결하고 이어서 인상재를 사용하여 구강 내에서 예비 인상을 채득 후 임프레션 코핑을 제거한다.Next, the impression coping is fastened to the fixture 500 to form a prosthesis, and then the impression coping is removed after taking a preliminary impression in the oral cavity using an impression material.
그런 다음에, 치아 모형을 제작하고 인공치관을 기공한 후 픽스츄어(500) 상부에 어버트먼트(400)를 체결하고, 어버트먼트(400) 위에 보철물, 즉 인공치관을 고정하여 인공치아를 완성하게 된다.Then, after making a tooth model and pore the artificial dental crown, the abutment 400 is fastened to the upper part of the fixture 500, and the prosthesis, that is, the artificial dental tooth is fixed on the abutment 400, You are done.
여기서 도 1(a)를 참조하면, 어버트먼트(400)는 스크류(미도시) 등에 의해 픽스츄어(500)에 고정될 수 있는데, 어버트먼트(400)와 픽스츄어(500)가 맞닿는 부분은 억지끼움 방식으로 결합(도 1의 X 부분 참조)될 수 있다.Referring to FIG. 1A, the abutment 400 may be fixed to the fixture 500 by a screw (not shown) or the like, and the portion where the abutment 400 and the fixture 500 contact each other. May be combined in an interference fit manner (see part X in FIG. 1).
즉 도 1(a)를 참조하여 예를 들어 설명하면, 어버트먼트(400)에는 스크류(미도시)가 삽입될 수 있는 관통공(410)이 형성될 수 있으며, 어버트먼트(400)가 픽스츄어(500)에 억지끼움 방식으로 결합(도 1의 X 부분)된 후 결합력을 더욱 부가하기 위하여 관통공(410)을 통해 스크류(미도시)를 삽입하여 픽스츄어(500)와 어버트먼트(400)를 결합하게 된다.That is, referring to FIG. 1A, for example, a through hole 410 into which a screw (not shown) may be inserted may be formed in the abutment 400, and the abutment 400 may be formed. The fixture 500 and the abutment are inserted into the fixture 500 by inserting a screw (not shown) through the through-hole 410 in order to further add the bonding force after being coupled (part X of FIG. 1). 400 will be combined.
여기서 어버트먼트(400)의 단부는 헥사 타입, 즉 육각 볼트 형태(도 1의 Y 부분 참조)로 형성되어 억지끼움 방식이 아니라 단순히 픽스츄어(500)에 안착되도록 마련될 수 있다. 다만 이는 하나의 예시일 뿐으로 본 발명의 권리범위가 이에 한정되는 것은 아니며 어버트먼트(400)의 단부는 사각형 등 다양한 형상을 가질 수 있다.Here, the end portion of the abutment 400 may be formed in a hexa type, that is, in the form of a hexagonal bolt (refer to the Y part of FIG. 1) to be seated in the fixture 500 instead of the interference fit method. However, this is just one example, and the scope of the present invention is not limited thereto. The end portion of the abutment 400 may have various shapes such as a square.
그런데 어버트먼트(400)에는 저작력 뿐만 아니라 다양한 외력이 작용하므로, 임플란트를 계속적으로 사용하게 되면 도 1(b)에서와 같이 픽스츄어(500)에 결합된 어버트먼트(400)의 일부분이 파절될 수 있다.By the way, the abutment 400, as well as a variety of external force acts on the operation, if you continue to use the implant portion of the abutment 400 coupled to the fixture 500 as shown in Figure 1 (b) fracture Can be.
여기서 스크류(미도시)는 용이하게 제거될 수 있지만 어버트먼트(400)와 픽스츄어(500)에 억지끼움 방식으로 결합되어 있는 부분(도 1의 X 부분)은 상호간의 결합력에 의해 제거하는 것이 상당히 어렵다는 문제가 있다.Here, the screw (not shown) may be easily removed, but the portion (X part of FIG. 1) coupled to the abutment 400 and the fixture 500 in an interference fit manner may be removed by mutual coupling force. There is a problem that is quite difficult.
이러한 문제를 해결하기 위해 본 발명의 제1실시예에 따른 어버트먼트 제거 드릴(100)은, 어버트먼트(400)의 파절된 부분을 절삭하여 삭제하는 방식으로 제거하도록 마련되는 바, 이하 이에 대해 상세히 설명한다.In order to solve this problem, the abutment removal drill 100 according to the first embodiment of the present invention is provided to remove the fractured portion of the abutment 400 by cutting and deleting the same. This will be described in detail.
도 2 및 도 3을 참조하면, 드릴비트유닛(200)은 픽스츄어(500)에 결합되어 파절된 어버트먼트(400)의 잔존부분(400a, 도 1(b) 참조)을 제거하도록 마련된다. 여기서 드릴비트유닛(200)은 어버트먼트(400)의 잔존부분(400a)을 절삭하도록 마련된다.2 and 3, the drill bit unit 200 is coupled to the fixture 500 to remove the remaining portions 400a (see FIG. 1B) of the fractured abutment 400. . Here, the drill bit unit 200 is provided to cut the remaining portion 400a of the abutment 400.
그리고 도 2를 참조하면, 드릴비트유닛(200)은, 드릴비트헤드(210)와, 회전샤프트(220)를 포함할 수 있다.2, the drill bit unit 200 may include a drill bit head 210 and a rotation shaft 220.
드릴비트헤드(210)는 어버트먼트(400)의 잔존부분(400a)에 접촉되어 어버트먼트(400)를 제거하도록 마련되는 것으로서, 어버트먼트(400)를 절삭하는 절삭부(211)와, 절삭부(211)를 가이드하는 절삭가이드부(212)를 포함할 수 있으며, 스토퍼부(213)를 포함할 수 있다.The drill bit head 210 is provided to contact the remaining portion 400a of the abutment 400 to remove the abutment 400, and the cutting portion 211 for cutting the abutment 400 and The cutting guide unit 212 may guide the cutting unit 211, and may include a stopper unit 213.
절삭부(211)는 어버트먼트(400)의 잔존부분(400a)에 접촉하여 회전하게 되는데, 이에 의해 어버트먼트(400)의 잔존부분(400a)을 절삭할 수 있게 된다.The cutting part 211 is rotated in contact with the remaining portion 400a of the abutment 400, thereby cutting the remaining portion 400a of the abutment 400.
즉 도 4(a)를 참조하여 예를 들어 설명하면, 픽스츄어(500)에 결합되어 있는 어버트먼트(400)의 일측이 파절되는 경우 픽스츄어(500)에 끼움결합되어 있는 어버트먼트(400)의 잔존부분(400a)은 픽스츄어(500)에 끼어져 있는 상태로 용이하게 제거되지 않게 된다.That is, referring to FIG. 4 (a), for example, when one side of the abutment 400 coupled to the fixture 500 is broken, the abutment fitted to the fixture 500 ( The remaining portion 400a of the 400 is not easily removed in a state of being fitted to the fixture 500.
그런데 어버트먼트(400)에는, 어버트먼트(400)와 픽스츄어(500)를 결합시키기 위한 스크류(미도시)가 삽입되는 관통공(410)이 형성될 수 있으므로, 절삭부(211)가 어버트먼트(400)의 잔존부분(400a)에 정확하게 접촉되어 절삭가능하도록 절삭부(211)를 가이드하는 절삭가이드부(212)가 절삭부(211)의 단부로부터 연장되어 마련되며, 절삭가이드부(212)는 어버트먼트(400)에 형성된 관통공(410)을 따라 이동하면서 절삭부(211)를 가이드하게 된다.However, in the abutment 400, since the through hole 410 into which a screw (not shown) for coupling the abutment 400 and the fixture 500 may be formed may be formed, the cutting part 211 may be formed. A cutting guide portion 212 for guiding the cutting portion 211 to be in contact with the remaining portion 400a of the abutment 400 to be cut is provided extending from an end of the cutting portion 211, and the cutting guide portion 212 guides the cutting part 211 while moving along the through hole 410 formed in the abutment 400.
그리고 도 4(b)를 참조하면, 절삭가이드부(212)의 가이드에 따라 절삭부(211)는 어버트먼트(400)에 형성된 관통공(410)을 따라 정확하게 이동하여 위치하게 되고 이후 어버트먼트(400)의 잔존부분(400a)을 절삭하게 된다.4 (b), the cutting part 211 is accurately moved along the through hole 410 formed in the abutment 400 and is positioned according to the guide of the cutting guide part 212. The remaining portion 400a of the garment 400 is cut.
여기서 절삭부(211)에 의해 어버트먼트(400)의 잔존부분(400a)이 절삭되는데, 어버트먼트(400)의 잔존부분(400a)이 모두 절삭될 수도 있지만 도 5(a)에서와 같이 완전히 절삭되지 않고 미세하게 남는 미절삭분(400b)이 있을 수 있다.Here, the remaining portion 400a of the abutment 400 is cut by the cutting portion 211. Although all of the remaining portion 400a of the abutment 400 may be cut, as shown in FIG. There may be finely divided powder 400b that remains fine and not completely cut.
하지만 어버트먼트(400)의 잔존부분(400a)이 중심으로부터 절삭되면서 얇아지게 되면 픽스츄어(500)와 어버트먼트(400) 사이에 작용하는 결합력이 차츰 감소하게 되므로, 절삭부(211)가 픽스츄어(500) 외부로 빠져나오게 되면 절삭부(211)와 함께 회전하면서 절삭되지 않고 남아 있는 미절삭분(400b) 역시 픽스츄어(500) 외부로 빠져나오게 된다.However, when the remaining portion 400a of the abutment 400 becomes thin while being cut from the center, the coupling force acting between the fixture 500 and the abutment 400 gradually decreases, so that the cutting portion 211 is When it comes out of the fixture 500, the uncut powder 400b that remains uncut while being rotated together with the cutting part 211 also exits the fixture 500.
또는 절삭완료 후 픽스츄어(500)를 뒤집는 경우 어버트먼트(400)의 절삭되지 않고 남아 있는 미절삭분(400b)이 결합력의 약화에 따라 픽스츄어(500) 외부로 용이하게 빠져나오게 된다.Alternatively, when the fixture 500 is inverted after the cutting is completed, the uncut portion 400b remaining in the abutment 400 without being cut is easily taken out of the fixture 500 according to the weakening of the coupling force.
즉 어버트먼트(400)의 잔존부분(400a)을 절삭하게 되면 미절삭분(400b)이 남더라도 도 5(b)에서와 같이 미절삭분(400b)이 어버트먼트(400)로부터 용이하게 빠져나올 수 있게 된다.That is, when the remaining portion 400a of the abutment 400 is cut, the uncut portion 400b is easily pulled away from the abutment 400 even as the uncut portion 400b remains. I can come out.
이 경우 헥사 타입 형태로 형성된 어버트먼트(400)의 단부(도 5의 Y 부분 참조)는 억지끼움 방식으로 결합되는 것이 아니므로, 절삭되지 않더라도 용이하게 제거될 수 있다.In this case, the end portion of the abutment 400 formed in the hexa type (see the Y portion of FIG. 5) is not coupled in an interference fit manner, and thus can be easily removed even if not cut.
한편, 도 4(a) 및 도 4(b)를 참조하면, 절삭가이드부(212)에는 간섭감소테이퍼부(218)가 마련될 수 있다. 이는 절삭가이드부(212)가 관통공(410)에 삽입되는 경우 어버트먼트(400)의 잔존부분(400a)과 간섭이 일어나는 것을 감소시키기 위함이다.Meanwhile, referring to FIGS. 4A and 4B, the interference reducing taper 218 may be provided in the cutting guide part 212. This is to reduce the occurrence of interference with the remaining portion 400a of the abutment 400 when the cutting guide portion 212 is inserted into the through hole 410.
즉 절삭가이드부(212)가 관통공(410)으로부터 벗어난 위치에서 관통공(410)에 삽입되는 경우 절삭가이드부(212)의 단부와 어버트먼트(400)의 잔존부분(400a)이 부딪히면서 간섭이 발생될 수 있다.That is, when the cutting guide portion 212 is inserted into the through hole 410 at a position away from the through hole 410, the end of the cutting guide portion 212 and the remaining portion 400a of the abutment 400 collide with each other. This may occur.
