일반적으로 치아는 음식물을 잘게 부수거나 갈아서 소화가 잘 되도록 도와주는 역할을 한다. 만일 이러한 치아가 소실되면 음식을 제대로 씹을 수 없고 소화가 잘 안되므로 음식을 마음껏 먹을 수 없을 뿐만 아니라 영양분의 원활한 섭취도 곤란하게 된다. 따라서 치아는 예로부터 신체의 중요한 부분으로 인식되어 왔고, 건강한 삶을 영위하는데 중요한 역할을 하고 있다. 인간의 치아는 아동기에 1회에 걸쳐 영구치로 교환된 이후에는 치아를 상실하게 될 경우 더 이상 새로운 치아가 생겨나지 않으므로 치과에서 보철치료를 통해 상실된 치아나 그 주위조직을 수복하여 저작기능 등을 회복할 수있다.Generally, teeth play a role in helping digest food well by grinding or grinding. If these teeth are lost, the food can not be chewed properly and the digestion is not easy, so that not only the food can be freely consumed, but also the nutrient intake is difficult. Thus, teeth have been recognized as an important part of the body since ancient times, and play an important role in maintaining a healthy life. Since human teeth are replaced with permanent teeth once in childhood, new teeth are not created when teeth are lost. Therefore, dentistry restores lost teeth and surrounding tissues through prosthetic treatment, .

일반적으로 자연치아의 인공 대체물로서의 사용되는 임플란트는 인공치근에 해당하는 픽스츄어(fixture), 지대주에 해당하는 어버트먼트(abutment), 인공치아의 세 부분으로 구성된다. 픽스츄어는 자연치아의 치근과 같이 결손된 치아부위의 치조골 속에 심어져 인공치아를 지지하도록 되어 있는 고정체이다. 어버트먼트는 지대치라고도 하며 잇몸에 심어져서 치조골에 심겨져 있는 픽스츄어와 인공치아를 연결하도록 되어 있다.In general, an implant used as an artificial substitute of a natural tooth is composed of three parts: a fixture corresponding to an artificial root, an abutment corresponding to an abutment, and an artificial tooth. A fixture is a fixture that is implanted in the alveolar bone of a missing tooth area like the root of a natural tooth to support an artificial tooth. The abutment is also called an abutment tooth, which is attached to the gum to connect the fixture, which is planted in the alveolar bone, to the artificial tooth.

그리고 본 발명의 하부고정체와 어버트먼트와 체결스크류는 티타늄같은 금속재질로 구성되며, 상기 티타늄은 비중과 열전도도와 열팽창률은 작으며, 경도가 높고 내식성이 좋으며, 뼈에 붙는 유착률이 높다는 장점이 있다.
The lower fixture, the abutment and the fastening screw of the present invention are made of a metal such as titanium, and the titanium has a small specific gravity, a low thermal conductivity and a low coefficient of thermal expansion, a high hardness and a high corrosion resistance, There are advantages.

따라서 본 발명은 체결스크류에 의해 결합된 어버트먼트와 하부고정체(fixture)가 체결스크류에 형성된 이탈방지홈에 의하여 쉽게 풀어지지 않게 되므로 임플란트를 장기간 안정적으로 사용할 수 있는 현저한 효과가 있다.
Therefore, according to the present invention, since the abutment and the fixture combined by the fastening screw are not easily released by the release preventing groove formed in the fastening screw, there is a remarkable effect that the implant can be stably used for a long period of time.
