본 발명은 임플란트용 어버트먼트 구조체에 관한 것으로, 더욱 상세하게는 어버트먼트와 어버트먼트를 픽스처에 결합시키는 결합수단에 각각 탄성체가 고정됨으로써, 크라운과 어버트먼트 사이의 이격 공간에 대한 밀폐력을 극대화하여 외부 타액의 침입을 차단하여, 세균 번식에 의한 악취가 발생하는 것을 방지할 수 있는 임플란트용 어버트먼트 구조체에 관한 것이다.The present invention relates to an abutment structure for an implant, and more particularly, by fixing an elastic body to each of the coupling means for coupling the abutment and the abutment to the fixture, sealing force for the space between the crown and the abutment It relates to an abutment structure for implants that can prevent the occurrence of bad odors due to bacterial propagation by maximizing the intrusion of external saliva.
일반적으로, 치과용 임플란트(dental implant)는 상실된 치아의 치근(뿌리)을 대신할 수 있도록 자연치근이 빠져나간 치조골에 인공치근인 픽스쳐을 식립하여 유착시킨 후 인공치아인 크라운(crown)을 고정시켜 치아의 기능을 할 수 있는 대치물을 의미하는 것으로서, 통상적으로 치조골에 골 유착되어 치근기능을 수행하는 픽스쳐(fixture)와, 인공치아 기능을 수행하는 보철물인 크라운(crown)과, 상기 픽스쳐와 크라운을 서로 연결하는 어버트먼트(abutment)로 구성된다.In general, a dental implant is a dental implant by placing a fixture, which is an artificial tooth root, in the alveolar bone from which the natural root has escaped so as to replace the root of the lost tooth, and then attaching the fixture, which is an artificial tooth, to the tooth by fixing the crown. As meaning a replacement that can function as, a fixture that is usually osseointegrated to the alveolar bone to perform a root function, a crown that is a prosthesis that performs an artificial tooth function, and the fixture and the crown to each other It consists of an abutment that connects.
이러한 치과용 임플란트는 통상적으로 나사 결합 방식으로 고정되는 스크류 타입의 임플란트와, 치과용 접착제를 통해 고정되는 접착 타입의 임플란트로 구분되거나, 상기 스크류 타입 및 접착 타입이 복합적으로 작용되는 복합 고정 타입의 임플란트로 구분된다.These dental implants are generally divided into a screw type implant fixed by a screw coupling method and an adhesive type implant fixed through a dental adhesive, or a composite fixation type implant in which the screw type and the adhesive type are combined. is divided into
일 예로, 대한민국 등록특허공보 제10-1768410호에는, 상부 보철물의 보정이 요구되는 경우 해당 상부 보철물로부터 손쉽게 탈·분리되는 구조적 특성에 기인하여 상부 보철물의 보정 허용은 물론 취급 및 사용상 분해 조립의 극대화가 유도되는 상부 보철물의 보정을 가능하게 하는 탈·부착형 록킹 링크 및 이를 이용한 상부 보철물 조립방법이 게재된 바 있다.For example, in Korean Patent No. 10-1768410, when correction of the upper prosthesis is required, due to the structural characteristics of being easily detached and separated from the upper prosthesis, correction of the upper prosthesis is allowed, as well as maximization of disassembly and assembly for handling and use A detachable/attachable locking link that enables the correction of the upper prosthesis induced by the prosthesis and a method of assembling the upper prosthesis using the same have been published.
그러나, 전술한 선행기술문헌에 의하면, 보철물(크라운)의 결합 과정에서 해당 보철물의 잦은 탈착으로 인해 치은 열구가 깊어져서 임플란트 주위염이나 임플란트 주위 점막염의 발생 가능성이 높아지는 문제점이 있다.However, according to the above-mentioned prior art literature, there is a problem in that the possibility of peri-implantitis or peri-implant mucositis increases due to the deepening of the gingival fissure due to frequent detachment of the prosthesis during the bonding process of the prosthesis (crown).
또한, 보철물에 록킹 링크의 결합부를 삽입할 때 억지 끼움에 의해 고정되도록 형성되어 있으므로 구강 내에 장착 후 시간이 지남에 따라 결합부가 변형되거나 파손될 가능성이 높아져 반복적인 유지 보수가 필요하고, 유지 보수를 하는 경우 치은이 손상될 우려가 매우 높아 유지 보수만을 위하여 막대한 시간이 소요될 수 밖에 없는 문제점이 있다.In addition, since it is formed to be fixed by force fitting when inserting the coupling part of the locking link into the prosthesis, there is a high possibility that the coupling part will be deformed or damaged over time after it is installed in the oral cavity, requiring repeated maintenance and maintenance. In this case, the risk of damage to the gingiva is very high, so there is a problem in that it takes a huge amount of time only for maintenance.
본 발명의 목적은, 어버트먼트와 이 어버트먼트를 픽스처에 결합시키는 결합수단에 각각 탄성체가 고정됨으로써, 크라운과 어버트먼트 사이의 이격 공간에 대한 밀폐력을 극대화하여 외부 타액의 침입을 차단하는 임플란트용 어버트먼트 구조체를 제공하는데 그 목적이 있다.An object of the present invention is to block the intrusion of external saliva by maximizing the sealing force for the separation space between the crown and the abutment by fixing the elastic body to each of the abutment and the coupling means for coupling the abutment to the fixture.

또한, 본 발명은 탄성체에 의해 크라운이 어버트먼트에 가체결된 상태에서 교합 조정 작업이 이루어지도록 함으로써, 크라운의 교합 조정시 해당 크라운이 어버트먼트로부터 잦은 탈락이 발생하는 것을 방지할 수 있고, 크라운 고정을 위한 고정수단의 반복적은 체결 및 풀림 작업을 수행하지 않더라도 쉽고 간단하게 교합 조정 작업을 수행할 수 있는 임플란트용 어버트먼트 구조체를 제공하는데 그 목적이 있다.In addition, the present invention allows the occlusal adjustment operation to be performed in a state in which the crown is pre-fastened to the abutment by an elastic body, thereby preventing the crown from frequently falling off from the abutment during occlusion adjustment of the crown, An object of the present invention is to provide an abutment structure for an implant that can easily and simply perform occlusal adjustment without performing repetitive fastening and loosening operations of the fixing means for fixing the crown.
또한, 본 발명은 어버트먼트가 힐링 어버트먼트의 기능을 더 수행할 수 있도록 구성됨으로써, 임플란트 픽스처의 고정 및 안정에 도움을 줄 수 있음은 물론, 힐링 어버트먼트를 사용하지 않아도 안정적으로 치은과의 긴밀한 결합이 가능함에 따라 어버트먼트와 치은 간의 결속력을 안정적으로 유지할 수 있는 임플란트용 어버트먼트 구조체를 제공하는데 그 목적이 있다.In addition, the present invention is configured so that the abutment can further perform the function of the healing abutment, thereby helping to fix and stabilize the implant fixture, as well as stably the gingiva without using the healing abutment. An object of the present invention is to provide an abutment structure for an implant that can stably maintain the bonding force between the abutment and the gingiva as close coupling with the tooth is possible.
