Abstract

PURPOSE: A dental implant is provided to prevent screw from being bent or broken or an abutment in which the dental prosthesis is fixed from being arbitrarily revolved. CONSTITUTION: A dental implant comprises a fixture(3) which is implanted to an alveolar bone, an abutment(4) fixed through a screw, a dental prosthesis(6) fixed by using dental cement, and hanging grooves(9) for float prevention which is installed at an upper shoulder(shoulder: 8) of fixture. The abutment is fixed at the upper part of the fixture which is clinched to an alveolar bone using screws. If the dental prosthesis is fixed using dental cement, the abutment on which the dental prosthesis is fixed is prevented to be arbitrarily floated and revolved. A plurality of hanging grooves for float prevention is formed at the upper shoulder of the fixture.

Description

치과용 임플란트{Dental implant}Dental Implants {Dental implant}

본 발명은 치과용 임플란트에 관한 것으로서, 더욱 상세히는 치조골에 식립한 픽스츄어에 고정되는 치과보철물이 음식물 저작시 오랜기간에 걸쳐 가해지는 저작압에 의해 치과보철물이 고정된 어버트먼트가 구강내에서 임의로 회전하거나 또는 어버트먼트를 고정하는 스크루가 휘거나 부러지는 폐단을 방지토록 한 치과용 임플란트를 제공코자 하는 것이다.
The present invention relates to a dental implant, and more particularly, the dental prosthesis fixed to the fixture placed in the alveolar bone is fixed in the oral cavity by the dental prosthesis fixed by the chewing pressure applied over a long period of time during the food authoring It is an object of the present invention to provide a dental implant which prevents a closed end of a screw that arbitrarily rotates or fixes an abutment.

치과용 임플란트는 치아가 상실된 부위에 인공치근인 픽스츄어(fixture)를 심어 치조골에 유착시키고, 유착된 픽스츄어에 치과보철물을 고정하여 형성된 인공치아구조를 지칭한다.The dental implant refers to an artificial tooth structure formed by implanting a fixture, which is an artificial tooth root, at the site where a tooth is lost, and attaching it to the alveolar bone, and fixing the dental prosthesis to the bonded fixture.

이와 같은 치과용 임플란트는 픽스츄어와, 상기 픽스츄어에 고정되는 어버트먼트(abutment)와, 상기 어버트먼트에 고정되는 치과보철물로 구성된다.The dental implant is composed of a fixture, an abutment fixed to the fixture, and a dental prosthesis fixed to the abutment.

이러한 치과용 임플란트는 치과보철물의 고정방식에 따라 나사 유지형과 시멘트 유지형으로 구분된다.These dental implants are divided into screw-type and cement-type according to the fixing method of the dental prosthesis.

나사 유지형 임플란트는 픽스츄어에 어버트먼트가 스크루에 의해 고정된 후 어버트먼트에 상부에 구멍이 뚫린 치과보철물을 치과용 시멘트로 고정한 뒤 치과용 레진으로 메워서 보철물에 문제가 생기면 레진을 제거한 후에 스크루를 풀어서 언제든 손쉽게 어버트먼트에서 제거할 수 있는 방식이며, 시멘트 유지형은 픽스츄어에 어버트먼트가 스크루에 의해 고정된 후 어버트먼트 상부에서 치과보철물을 치과용 시멘트를 사용하여 고정하는 방식이다.The screw-held implant is fixed to the fixture by a screw after fixing the dental prosthesis with a hole in the upper part of the abutment with dental cement and filling it with dental resin to remove the resin when the prosthesis has a problem. The screw can be easily removed and removed from the abutment at any time. The cement retaining type is a method of fixing the dental prosthesis at the top of the abutment using dental cement after the abutment is fixed to the fixture by the screw. .

상기 시멘트 유지형은 나사 유지형에 비해 수동적 적합을 쉽게 이룰 수 있어 시술이 비교적 용이하지만, 탈착을 조절하기가 쉽지 않다는 문제점이 있다. 즉, 너무 쉽게 떨어지거나 분리가 안되는 경우가 있고, 어버트먼트를 픽스츄어에 고정하는 스크루가 쉽게 휘거나 부러지는 폐단이 있었다.The cement retaining type is easier to achieve a passive fit than the screw retaining type, but the procedure is relatively easy, but there is a problem that it is not easy to control the detachment. In other words, there were cases where it was too easy to fall off or could not be separated, and there was a closed end where the screw fixing the abutment to the fixture was easily bent or broken.

그리고 자연치로 음식물을 씹을 때는 치주인대에서 충격을 흡수하여 저작압을 감쇄시켜 치아를 보호하지만, 임플란트는 치조골에 직접 식립되어 생리적인 움직임을 갖지 않아 치과보철물이 음식물을 씹을 때 그 하중(=저작압)이 보철물에 그대로 전해져 언제든지 치과보철물이 고정된 어버트먼트가 회전할 가능성이 일어 날수 있는 등의 문제점이 있어 이러한 문제를 해결할 수 있는 치과용 임플란트의 개발이 절실히 요망되어 왔던 것이다.
And when chewing food with natural teeth, the tooth is absorbed by the periodontal ligament to reduce the chewing pressure to protect the teeth, but the implant is placed directly on the alveolar bone and does not have physiological movement, so when the dental prosthesis chews food, the load (= low pressure) ) As it is transmitted to the prosthesis, there is a possibility that the abutment to which the dental prosthesis is fixed can rotate at any time. Therefore, there has been a great demand for the development of a dental implant that can solve this problem.

이에 본 발명에서 제공하는 치과용 임플란트는 픽스츄어 상부에서 스크루로 고정되는 어버트먼트와, 상기 어버트먼트에 치과용 시멘트를 사용하여 치과보철물을 고정시킨 후 음식물 저작시 오랜기간에 걸쳐서 작용하는 저작압 및 충격에 의해 치과보철물이 고정된 어버트먼트가 임의 회전하거나 스크루가 휘거나 부러지는 폐단을 일소할 수 있는 치과용 임플란트를 제공코자 하는 것이다.
The dental implant provided in the present invention is an abutment that is fixed with a screw on the upper part of the fixture, and a work that works over a long period of time during the authoring of food after fixing the dental prosthesis using dental cement to the abutment It is an object of the present invention to provide a dental implant capable of erasing a closed end where an abutment to which a dental prosthesis is fixed by pressure and impact is arbitrarily rotated, bent or broken.

이에 본 발명에서는 상기한 바와 같은 과제를 달성하기 위해 다음과 같은 치과용 임플란트를 제공코자 한다.In the present invention, to provide a dental implant as follows to achieve the above problems.

즉, 본 발명의 치과용 임플란트는 픽스츄어 상부 숄더에 다양한 모양의 수개의 유동방지용 걸림홈을 형성하고, 상기 걸림홈에 대응하여 걸림고정되는 걸림턱을 치과보철물에 형성한 것을 특징으로 한다.
That is, the dental implant of the present invention is characterized in that a plurality of flow preventing locking grooves of various shapes are formed in the upper shoulder of the fixture, and the locking jaw is formed on the dental prosthesis to correspond to the locking groove.

본 발명에서 제공하는 치과용 임플란트는 픽스츄어와 치과보철물, 또는 픽스츄어와 어버트먼트 접착 고정 대응면에 걸림홈과 걸림턱을 수개 대응하여 걸림고정이 동시에 이루어질 수 있도록 하여 임플란트 식립 후 음식물을 저작시 장기간에 걸친 저작압 및 충격에 의해 치과보철물이 고정된 어버트먼트가 임의 회전하거나 스크루가 휘거나 부러지는 폐단을 일소할 수 있는 매우 유용한 발명이다.
Dental implants provided in the present invention by making a number of locking grooves and the jaw to correspond to the fixture and the dental prosthesis, or the fixture and abutment adhesive fixing corresponding surface at the same time to secure the fastening of the food after implantation It is a very useful invention that the abutment in which the dental prosthesis is fixed by the chewing pressure and the impact over a long period of time can wipe out the end of the rotation, the screw bent or broken.
