Abstract

The nano-surface modification techniques could be classified; internal modifications which enhance surface roughness and porosity in nano level and external modifications as nano particle coating. Nano-modified implant surface has various morphograpies such as nanotube, nanopit, nanonodule and polymorphic structures. Creating surface depends upon preparation method and material, however, there is no standard preparation technique not yet. The nano-modified surfacet is electrochemically stable comparing with the surface modified in micron level. Nano-modified surface has little cytotoxicity, stimulates osteoblast proliferation and differentiation. Moreover, it decreases soft tissue intervention by interrupting the proliferation of fibroblast. Nanostructure has similar size and shape with cells and proteins, consequently leads to good biocompatibility and enhanced osseointegration. However, the actual effect in vivo is limited, due to the distance of effect. Even if nano-modified surface has antibiotic property due to photocatalysis, short duration time makes clinical application questionable. Further investigations should focus on the optimal nano-modified surface, which has many potentials.

티타늄 산화막을 나노단위에서 변형시키는 방법은 다공성 표면을 강화하는 내부적 접근과 나노입자를 피복하는 외부적 접근으로 나눌 수 있다. 나노표면은 나노튜브, 나노피트, 나노노듈 및 다형구조 등 다양한 형태를 지닌다. 형성방법 및 형성재료에 따라 다른 표면이 생성되지만, 현재까지 표준화된 형성방법은 없다. 나노표면을 분석해 보면 마이크론 단위의 표면구조에는 영향을 미치지 않으며 전기화학적으로 안정적이다. 나노표면은 세포독성이 거의 없으며 조골세포의 증식과 분화를 모두 촉진하고, 섬유모세포의 증식을 저해하여 연조직 개재를 감소시키는 효과를 가진다. 또한 세포 및 단백질과 유사한 크기 및 형태를 가지기 때문에 조직과의 친화성이 우수하여 골유착을 증진시킨다. 하지만 그 작용이 미치는 범위는 극히 제한되어 있기 때문에 골조직과의 거리가 있는 경우에는 효과가 미미하다. 마이크론 단위의 표면과는 달리 나노표면은 광촉매효과로 인한 항균작용을 가지지만 지속시간이 짧아 실제 임상에서의 적용효과는 의문시 된다. 하지만 마이크론 단위의 표면거칠기가 가지는 단점을 배제할 수 있어 다양한 가능성을 가지기 때문에 더 많은 연구가 필요하다.
