본 고안은, 나사고정형의 장점을 살리고, 간단한 구조이면서도 풀림을 완전히 방지시켜 장기간 흔들림이 없이 치아를 사용할 수 있는 견고한 구조의 치아용 임플란트에 관한 것이다.The present invention relates to a dental implant of a rigid structure that can take advantage of the screw fixing type, and can use the teeth without shaking for a long time by completely preventing loosening.

종래의 치아용 임플란트에는, 접착형과 나사고정형이 있으며, 나사형 임플란트는, 잇몸 고정부재인 지대주에 인공 치아를 나사로 고정시키는 것이고, 접착형 임플란트는, 지대주에 인공 치아를 접합제로 접합시키는 것이다. 접착형의 경우 구조가 간단하다는 장점이 있으나, 한번 접합시킨 후에 필요에 따라 분리시키는 것이 나사고정형에 비해 매우 어렵다는 문제가 있다.Conventional dental implants include an adhesive type and a screw fixing type. A screw type implant is to fix an artificial tooth to an abutment which is a gum fixing member, and an adhesive implant is to bond an artificial tooth to abutment with a bonding agent. In the case of the adhesive type, there is an advantage that the structure is simple, but there is a problem that it is very difficult compared to the screw-mounted type after the bonding once separated.

나사고정형의 경우에는, 필요에 따라 상부의 치아고정부재를 제거할 수 있어 편리하지만, 체결 내지 고정나사의 풀림이 발생하는 경우, 치아가 흔들리게 되는 등의 문제가 발생하게 된다.In the case of screw fixing type, it is convenient to remove the upper tooth fixing member as needed, but when the fastening or loosening of the fixing screw occurs, a problem such as the tooth shaking occurs.

따라서, 이러한 나사의 풀림을 저감시키거나 방지시키기 위해 다양하게 개발이 이루어지고 있으나, 여전히 완전한 풀림의 방지를 해결하지는 못하고 있다. 나사풀림의 원인으로는 부정확한 금속구조물의 적합, 부정교합, 이 악물기나 알치증과 같은 비기능력, 과도하게 연장된 캔틸레버에 의한 과하중, 단일 수복치에 가해진 비트는 힘, 고정나사의 불량한 적합 등에 기인한 것으로 알려져 있다.Therefore, various developments have been made to reduce or prevent such loosening of screws, but still do not solve the prevention of complete loosening. Causes of screw loosening include incorrect fit of metal structures, misalignment, aggravation such as gutter or alkalosis, overload by an overly extended cantilever, twisting force applied to a single restoration, poor fit It is known that it originates from etc.

따라서, 본 고안은, 이러한 문제를 해결하기 위한 것으로, 나사고정형의 장점을 살리고, 간단한 구조이면서도 풀림을 완전히 방지시켜 장기간 흔들림이 없이 치아를 사용할 수 있는 견고한 구조의 치아용 임플란트를 제공하는 데에 그 목적이 있다.Accordingly, the present invention is to solve this problem, to take advantage of the screw fixing type, and to provide a dental implant of a rigid structure that can be used for a long time without shaking by using a simple structure and completely prevent loosening. There is a purpose.

이러한 목적을 달성하기 위해 본 고안의 일실시예에 따른 치아용 임플란트는, 매립부가 잇몸에 매립되어 잇몸에 고정되는 잇몸 고정부재와, 외주에 치아가 고정되고 상기 잇몸 고정부재에 대해 체결나사를 개재하여 고정되며, 체결나사의 몸체부 및 숫나사부가 관통되는 체결나사관통공과, 체결나사의 머리부가 걸려 안착되는 체결나사헤드안착부와, 그 체결나사의 머리부가 수용되는 체결나사헤드수용부가 형성된 치아고정부재를 포함하여 구성되는 치아용 임플란트에 있어서, 상기 잇몸 고정부재와 치아고정부재사이에 배치되고, 그 잇몸 고정부재에 용접, 리벳팅, 나사체결 등에 의해 결합고정되며, 치아고정부재를 고정시키기 위해 체결나사의 몸체부 및 숫나사부가 관통하여 체결고정되는 관통공 및 암나사공이 형성되고, 그 암나사공의 중간에 풀림방지절개부가 형성되며, 그 풀림방지절개부의 상하의 암나사중 일측이 상대적으로 변형된 풀림방지부재를 구비함으로써 체결나사의 체결시 그 상대적으로 변형된 암나사가 복원되는 변형량에 의해 체결토크가 증대되고 풀림이 방지되는 것을 특징으로 한다.In order to achieve this purpose, the dental implant according to the embodiment of the present invention, the buried part is embedded in the gum and the gum fixing member is fixed to the gum, the tooth is fixed to the outer circumference through the fastening screw for the gum fixing member Fastening screw through-hole through which the body part and the male thread part of the fastening screw are penetrated, the fastening screw head seating part where the head of the fastening screw is caught, and the fastening screw head receiving part where the head of the fastening screw is accommodated. In the dental implant comprising a member, disposed between the gum fixing member and the tooth fixing member, and is fixed to the gum fixing member by welding, riveting, screwing, etc. to secure the tooth fixing member A through hole and a female thread hole are formed through which the body portion and the male thread portion of the fastening screw penetrate and are fastened. An anti-loosening section is formed, and one of the upper and lower female threads of the anti-loosening section has a loosening preventing member that is relatively deformed, so that the tightening torque is increased and released by the amount of deformation that the relatively deformed female screw is restored when the tightening screw is tightened. This is characterized by being prevented.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예(들)를 상세히 설 명하면 다음과 같다.Hereinafter, preferred embodiment (s) of the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 7에는 본 고안의 일실시예에 따른 치아용 임플란트의 구성을 도시한 분해사시도 및 조립단면도가 도시되며, 도 2, 도 3a 내지 도 3c, 도 4 및 도 5에는 그 치아용 임플란트를 구성하는 도 1의 잇몸 고정부재(10), 풀림방지부재(20), 치아고정부재(30) 및 체결나사(40)가 도시된다.1 and 7 are exploded perspective and assembly cross-sectional view showing the configuration of the dental implant according to an embodiment of the present invention, Figure 2, Figures 3a to 3c, 4 and 5 for the dental implant 1, the gum fixing member 10, the anti-loosening member 20, the tooth fixing member 30, and the fastening screw 40 of FIG. 1 are illustrated.

도 2에서, 잇몸 고정부재(10)는, 상기 매립부(11)가 잇몸 내지 치조골에 매립되어 잇몸에 고정되며, 본 고안에 따라 제공되는 풀림방지부재(20)가 그 잇몸 고정부재(10)에 용접, 리벳팅, 나사체결 등에 의해 결합고정되는데, 도 2 내지 3b 및 도 6에서는 상세히 후술되는 바와 같은 리베팅 결합고정 구조의 일예가 도시된다. 이와 같은 구조에서는 리베팅 돌출부(18)가 내측으로 변형되어 잇몸 고정부재(10)에 형성된 원주결합홈(28)으로 결합함으로써 고정되게 된다.In Figure 2, the gum fixing member 10, the buried portion 11 is embedded in the gum or alveolar bone is fixed to the gum, the loosening prevention member 20 provided according to the present invention is the gum fixing member 10 The joint is fixed by welding, riveting, screw fastening, etc. In FIGS. 2 to 3b and 6, an example of the riveting fastening structure as described below in detail is shown. In such a structure, the riveting protrusion 18 is deformed inward and fixed by engaging the circumferential coupling groove 28 formed in the gum fixing member 10.

이와 같이 잇몸 고정부재(10)에 결합고정되는 풀림방지부재(20)는, 그 상부에 치아고정부재(30)가 배치되고, 그 치아고정부재(30)를 고정시키기 위해 체결나사(40)의 몸체부(41) 및 숫나사부(42)가 도 7에 도시된 바와 같이 관통하여 체결고정되는 관통공(25a) 및 암나사공(27a)이 도 3a에 도시된 바와 같이 그 풀림방지부재(20)에 형성되며, 체결나사(40)의 풀림을 방지시키기 위해 그 암나사공(27a)의 중간에 풀림방지절개부(27b)가 형성된다. 그 풀림방지절개부(27b)의 단부에는 도 3a내지도 3c에서와 같이 응력집중방지공(27c)이 형성되는 것이 바람직하다.In this way, the anti-loosening member 20 coupled to the gum fixing member 10 has a tooth fixing member 30 disposed thereon, and the fastening screw 40 is fixed to fix the tooth fixing member 30. As shown in FIG. 3A, the through-hole 25a and the female screw hole 27a through which the body portion 41 and the male screw portion 42 are fastened and fastened as shown in FIG. Is formed in, to prevent the loosening of the fastening screw 40, the anti-loosening portion 27b is formed in the middle of the female screw hole (27a). At the end of the loosening prevention cutout 27b, it is preferable that a stress concentration preventing hole 27c is formed as shown in Figs. 3A to 3C.

그 풀림방지절개부(27b)의 상하의 암나사공(27a)은, 도 3b에 도시된 바와 같이 그 풀림방지절개부(27b)의 상하의 암나사의 일측이 다른 일측에 대해 상대적으 로 변형되어 구성됨으로써 도 7 및 도 8에서와 같이 체결나사(40)의 체결시 그 상대적으로 변형된 하측의 암나사가 복원되는 탄성 변형량에 의해 체결토크가 증대되게 되고 그 만큼 한번 체결되면, 그 체결토크이상의 토크가 작용하지 아니하면, 그 풀림이 이루어질 수 없게 되어 체결나사(40)의 풀림이 방지되게 된다. 그 재질과 탄성변형량에 따라 체결토크는 변화될 수 있다. 예를 들어, 암나사공(27a)을 형성한 후, 도 3b에서와 같이 그 풀림방지절개부(27b)의 상하의 암나사의 일측인 하측을 다른 일측인 상측에 대해 상대적으로 실선의 화살표 A의 상태로부터 이점쇄선의 화살표 B 또는 C의 상태로 펀칭하여 소성 변형시킴으로써 변형되게 구성될 수 있으며, 암나사부의 상하측 사이의 상대적 변형은 반드시 이에 한정되지는 아니하며, 변형 방법도 반드시 펀칭에 한정되는 것은 아니다.The upper and lower female thread holes 27a of the loosening prevention cutout 27b are formed by deforming one side of the upper and lower female threads of the loosening prevention cutout 27b relatively to the other side as shown in FIG. 3B. As shown in FIG. 7 and FIG. 8, when the fastening screw 40 is fastened, the tightening torque is increased by the amount of elastic deformation in which the relatively deformed lower female thread is restored, and once the fastening torque is increased, the torque beyond the tightening torque does not work. Otherwise, the loosening can not be made so that the loosening of the fastening screw 40 is prevented. The tightening torque may vary depending on the material and the amount of elastic deformation. For example, after the female thread hole 27a is formed, as shown in Fig. 3B, the lower side of one side of the upper and lower female threads of the loosening prevention cutout portion 27b is relatively inclined from the state of the arrow A relative to the other side of the upper side. It may be configured to be deformed by punching in the state of the arrow B or C of the two-dot chain line, and the deformation is not necessarily limited to the above, and the deformation method is not necessarily limited to punching.

또, 도 8에서는이점쇄선의 화살표 B의 상태로부터 실선의 화살표 C의 상태로 각도 b만큼 탄성변형되면서 체결나사(40)가 체결되는 것이 도시되지만, 이에 한정되는 것은 아니며, 예를 들어 도 3b에서 변형된 상태가 이점쇄선의 화살표 A의 상태인 때에는 각도 a만큼 실선의 화살표 C의 상태로 탄성변형되면서 체결나사(40)가 체결되게 된다.8 shows that the fastening screw 40 is fastened while being elastically deformed by an angle b from the state of arrow B of the double-dotted line to the state of arrow C of the solid line, but is not limited thereto. For example, in FIG. When the deformed state is the state of arrow A of the double-dot chain line, the fastening screw 40 is fastened while being elastically deformed to the state of arrow C of the solid line by an angle a.

도 6에는 도 2의 잇몸 고정부재(10)와 도 3a 및 도 3c의 풀림방지부재(20)가 결합고정되는 과정이 단면도로 나타난다. 즉, 풀림방지부재(20)가 잇몸 고정부재(10)에 조립된 상태(도 6의 상부 상태)에서 리베팅 공구(50)를 잇몸 고정부재(10)에 대해 화살표로 표시된 방향인 상방으로 가압시키거나, 리베팅 공구(50)에 대해 잇몸 고정부재(10)를 하방으로 가압시키면, 리베팅 돌출부(18)가 내측, 즉 풀림방지부재(20)의 원주결합홈(28)으로 가압, 변형되어 결합됨으로써, 리벳팅에 의해 잇몸 고정부재(10)와 풀림방지부재(20)가 결합고정되게 된다. 결합고정구조는 이에 한정됨이 없이 다양한 공지기술이 채용될 수 있다.6 is a cross-sectional view illustrating a process in which the gum fixing member 10 of FIG. 2 and the anti-loosening member 20 of FIGS. 3A and 3C are coupled and fixed. That is, in the state where the anti-loosening member 20 is assembled to the gum fixing member 10 (the upper state of FIG. 6), the riveting tool 50 is pressed upwards in the direction indicated by the arrow with respect to the gum fixing member 10. Or press the gum fixing member 10 downward against the riveting tool 50, the riveting protrusion 18 is pressed into the inner side, that is, the circumferential coupling groove 28 of the loosening prevention member 20, and deformed. By being combined, the gum fixing member 10 and the loosening prevention member 20 are coupled and fixed by riveting. The coupling fixing structure is not limited thereto, and various known techniques may be employed.

이와 같이 하여 풀림방지부재(20)가 결합고정된 잇몸 고정부재(10)의 매립부(11)를 종래의 방식으로 잇몸 내지 치조골에 매립시키고 도 7에 도시된 바와 같이 치아고정부재(30)를 상부에 결합시켜 체결나사(40)로 체결하면, 도 8에 도시된 바와 같이, 풀림방지절개부(27b)의 형성후 변형된 암나사부의 일측(도 8에서는 하측)이 다시 복원되어 체결되게 되므로, 그 복원되는 탄성 변형량에 의해 체결토크가 증대되게 된다. 즉, 상기 상부암나사부와 하부암나사부사이의 상대적 변형 각도에 따라 숫나사 체결시 장력이 발생되며, 체결토크가 증가되게 된다.In this way, the buried portion 11 of the gum fixing member 10 to which the loosening prevention member 20 is coupled and fixed is embedded in the gum or alveolar bone in a conventional manner, and the tooth fixing member 30 is shown in FIG. 7.
