Abstract

The purpose of the present invention, relating to a crown removal device, is to provide a crown removal device which enables an operator to remove only a crown without damaging teeth by: putting each arm of forceps evenly on the occlusal surface of the buccolingual side of the crown; and then situating, on the occlusal surface of neighboring teeth, support rods equipped at the lower ends of the forceps and applying force in a lever manner. When the present invention is applied, force is evenly applied to the buccolingual side of the crown, and thus, damage to teeth can be prevented. In particular, the present invention has an advantage that since the crown is removed using a lever action, the operator may apply a relatively small force to remove the crown, thereby being able to delicately remove the crown from a tooth.

Description

크라운 제거장치Crown remover

본 발명은 크라운 제거장치에 관한 것으로, 보다 상세하게 시술자가 크라운의 협설측 치경부에 각각 집게부 양측을 균등하게 건 다음, 집게부 방향에 구비된 지지봉을 이웃하는 치아 교합면에 위치시키고 지렛대 방식으로 힘을 가함으로써 치아에 손상없이 크라운만을 제거할 수 있도록 한 크라운 제거장치에 관한 것이다.The present invention relates to a crown removing device, and in more detail, the operator evenly covers both sides of the forceps on the buccal side of the buccal side of the crown, and then places the support rods provided in the direction of the forceps on the adjacent tooth occlusal surface and in a lever manner. The present invention relates to a crown removal device that allows the removal of only the crown without damaging the tooth by applying force.

주지된 바와 같이, 충치란 치과용어로 치아우식증이라고 하며, 치태 형태로 치아에 서식하는 세균이 음식물 찌꺼기와 결합하여 배출되는 산에 의해 치아의 표면이 부식되어 손상되는 제 증상을 말하는 것이다. 충치는 크게 4 단계로 진행되는데, 제1 단계는 충치가 법랑질까지만 진행이 된 상태로 자각 증상이 없다. 제2 단계는 충치가 상아질까지 진행이 된 상태로 이가 시린 정도의 증상이 나타난다. 제3 단계는 충치가 치수까지 침범한 상태로 통증이 수반된다. 제4 단계는 치수가 완전히 부패하고 이 뿌리까지 염증이 전파된 상태로 저작이 곤란한 정도의 염증이 발생한다.As is well known, tooth decay is dental caries in dental terminology, and refers to a first symptom in which the surface of the tooth is corroded and damaged by acid discharged in combination with food waste in the form of plaque. Tooth decay proceeds in four stages. In the first stage, tooth decay proceeds only to enamel, without any symptoms. In the second stage, tooth decay progresses to the dentin, and the symptoms are as severe as ache. The third stage involves pain with cavities invaded to the pulp. In the fourth stage, inflammation is difficult to chew while the pulp is completely decayed and the inflammation has spread to the root.

이에, 단계별로 적절한 치료가 이루어진다. 제1 단계에서는 우식 부위를 떼어내고, 떼어낸 자리를 레진 등으로 가볍게 수복한다. 제2 단계에서도 마찬가지로 우식 부위를 떼어내는데, 이때 떼어낸 부위는 크기가 크기 때문에 골드 인레이(Gold Inlay)를 사용해 수복한다. 제3 단계에서는 충치의 제거량이 많을 뿐 아니라, 신경이 손상되어 치질이 약해지므로 크라운을 씌워 주어야 한다. 제4 단계에서는 제3 단계와 거의 동일한 치료를 하며, 심한 경우 발치로 이어진다.Thus, appropriate treatment is achieved step by step. In the first step, the caries part is removed and the removed part is lightly repaired with a resin or the like. In the second step, the caries area is similarly removed, which is then repaired using a gold inlay due to its large size. In the third stage, not only is the amount of tooth decay removed, but the nerves are damaged and hemorrhoids are weakened. In the fourth stage, treatment is almost the same as in the third stage, and in severe cases leads to extraction.

특히, 충치 치료의 제3 및 4 단계에서 사용되는 크라운은 충치의 우식 부위를 제거하고 생긴 와동 등에 적절한 재료를 충전한 뒤, 그 위에 씌워 주는 보철물로서, 약해진 치아를 보호하고, 우식부위를 감싸주는 역할을 한다. 이와 같이 크라운을 씌우기 위해서는 도 1에 도시된 바와 같이, 충전물(2)을 채운 치아(1) 위에 시멘트와 같은 접착제(3)를 도포하고, 그 위에 크라운(4)을 씌워 고정하도록 되어 있다.In particular, the crown used in the third and fourth stages of caries treatment is a prosthesis that removes the caries part of the caries, fills the vortex with the appropriate material, and then covers the caries. Play a role. In order to cover the crown in this way, as shown in FIG. 1, an adhesive 3 such as cement is applied onto the tooth 1 filled with the filling 2, and the crown 4 is fixed on the tooth 1.

그런데, 위와 같이 크라운(4)을 이용하는 보철물은 사용되는 재료의 종류와, 환자의 칫솔질 습관 등에 따라 5년에서 10년 정도의 수명을 가지며, 따라서 수명이 다한 뒤에는 반드시 크라운을 제거하고, 치료를 다시 하여야 한다. 이를 위해서는 먼저, 치아(1)에 씌어져 있던 기존의 크라운(4)을 제거하여야 하는 바, 지금까지는 도 2 이하에 도시된 바와 같은 도구 들이 제안된 바 있다.However, as described above, the prosthesis using the crown 4 has a lifespan of about 5 to 10 years depending on the type of material used and the brushing habits of the patient. Therefore, after the end of life, the crown must be removed and the treatment again. shall. To this end, first, it is necessary to remove the existing crown (4) written on the tooth (1), until now the tools as shown in Figure 2 or less has been proposed.

도 2에 도시된 보철물제거용 집게(111)는 가위 형태로 되어 있으며, 짧은 집게 다리(113) 안쪽에 돌출된 지지턱(115)을 지점으로 하여 긴 집게 다리(117)를 화살표(A) 방향으로 회전시킴으로써 치아(1)에서 크라운(4)을 돌려 빼도록 되어 있다. 그러나, 이 집게(111)는 크라운(4)과 접촉하는 집게 다리(113,117)의 하단 내측면에 이빨(119)이 돌출되어 있음에도 불구하고 접촉면에서 미끄럼이 발생하므로 크라운(4)이 쉽게 빠지지 않고, 과도한 힘을 가하는 경우 치아(1)까지 손상되는 문제점이 있다.2, the prosthesis removal tongs 111 shown in FIG. 2 is in the form of scissors, and the long tongs leg 117 in the direction of the arrow A with the support jaw 115 protruding inside the short tongs leg 113 as a point The crown 4 is rotated and pulled out from the tooth 1 by rotating it. However, the tongs 111 do not easily fall out of the crown 4 because slipping occurs in the contact surface despite the protruding teeth 119 on the lower inner surfaces of the tongs legs 113 and 117 in contact with the crown 4. If excessive force is applied, there is a problem that damage to the tooth (1).

즉, 이 집게(111)는 크라운(4)만을 효율적으로 쉽게 제거할 수가 없었다는 문제가 있었고, 그러다 보니 불필요한 힘이 치아(1)쪽에 가해져서 치아가 더 손상되게 되는 문제가 있었다.That is, the forceps 111 had a problem that only the crown 4 could not be easily removed efficiently, and thus there was a problem that unnecessary force was applied to the tooth 1 to further damage the teeth.

또, 도 3에 도시된 갈고리 형태의 보철물 제거기(211)는 몸체를 이루는 봉체(213), 이 봉체(213)의 선단에 나사 결합된 걸이훅(215), 그리고 봉체(213) 후단의 확경부(219)를 타격하도록 봉체(213) 위에 미끄럼 가능하게 끼워진 타격체(217)로 구성되는 바, 도 4에 도시된 것처럼 걸이훅(215)의 팁(221)을 크라운(4)의 하단 테두리 부분에 걸고, 타격체(217)에 의해 확경부(219)를 타격함으로써 크라운(4)을 제거하도록 되어 있다. In addition, the prosthesis remover 211 having a hook shape shown in FIG. 3 includes a rod 213 constituting a body, a hook hook 215 screwed to the tip of the rod 213, and an enlarged diameter portion at the rear end of the rod 213. It consists of a striking body 217 slidably fitted over the rod 213 to strike the 219, the lower edge portion of the crown 4, the tip 221 of the hook hook 215 as shown in FIG. The crown 4 is removed by striking the enlarged diameter portion 219 by the striking member 217.

즉, 도 3에 도시된 갈고리 형태의 보철물 제거기(211)는 봉체(213)에 끼워서 슬라이딩되는 타격체(217)의 관성력을 다시 봉체(213)에 미치게 함으로써 크라운을 제거하는 기구지만, 이 보철물 제거기(211)도 마찬가지로 타격체(217)에 의한 타격 시 걸이훅(215)의 팁(221)이 움직이면서 주위의 치아나 잇몸에 상처를 입힐 수 있는 안전상의 문제점을 가지고 있으며, 따라서, 시술 시 주의를 기울여야 하는 사용상의 불편을 야기하는 문제점이 있었다.That is, the prosthesis remover 211 having a hook shape shown in FIG. 3 is a mechanism for removing the crown by extending the inertia force of the striking body 217 sliding into the rod 213 to the rod 213, but this prosthesis remover Similarly, 211 also has a safety problem that may damage the teeth or gums around the hook 215 of the hook hook 215 when the hit by the striking body 217, thus, pay attention to the procedure There was a problem causing inconvenience to use.

즉, 상기 타격체(217)의 관성력은 너무 빠른 순간에 봉체(213)에 가해지므로 시술자가 타격순간에 집중하지 않거나, 또는 약간의 실수만으로도 치아나 잇몸이 손상될 수 있다는 문제가 있었다.That is, since the inertial force of the hitting body 217 is applied to the rod body 213 at a too fast moment, there is a problem that the operator does not concentrate at the moment of hitting, or the tooth or the gum may be damaged even with a slight mistake.

이외에도 디스크형 회전톱을 사용하거나 도르래를 이용하는 등 크라운을 제거하는 다양한 시술 방식이 제안된 바 있으나, 시술 시 안전성이나 편리성이 고려되지 못한 문제점이 있었다.In addition, various procedures have been proposed to remove the crown, such as using a disk-type rotary saw or using a pulley, but there was a problem that safety or convenience was not considered during the procedure.

따라서, 도 2, 3에 도시된 보철물 제거기는 공히, 크라운(4)의 어느 한쪽에 편중된 힘이 가해지므로 단지 크라운(4)만을 깔끔하게 제거할 수 있는 것이 아니고 치아(1)를 손상할 수 있다는 문제가 가장 크다.Thus, the prosthesis remover shown in FIGS. 2 and 3 is not only capable of neatly removing the crown 4 but also damaging the tooth 1 because a biased force is applied to either side of the crown 4. The problem is the biggest.

본 발명은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 시술자가 크라운의 협설측 치경부에 각각 집게부 양측을 균등하게 건 다음, 집게부 방향에 구비된 지지봉을 이웃하는 치아 교합면에 위치시키고 지렛대 방식으로 힘을 가함으로써 치아에 손상없이 크라운만을 제거할 수 있도록 한 크라운 제거장치를 제공함에 그 목적이 있다.
