Insolubilized Properties of Collagen as Artificial Periodontal Membrane Irradiated by Plasma

生物相容性人工牙是老年人特别需要的，他们失去了他们的天然牙齿。最近，陶瓷植入体已被部分使用，但它们很难制成复杂的形状，从动力学的角度来看不适合。本研究考虑到天然牙与牙周膜的良好结合作用，对胶原作为人工牙周膜的不溶性进行了研究，发现人工牙周膜包覆磷灰石-胶原复合材料经等离子体和紫外线照射后，在大鼠体内显示出良好的生物相容性。然而，由于复合材料和人工牙周膜的机械性能不足以应用，进一步的研究正在进行中。

Biocompatible artificial teeth are desired especially by the old aged,who have lost their natural teeth.Recently, ceramic implants have been used in part, but they ar hard to make a complex form and not suitable from a dynamical view point. In this study, considering that natural teeth act well their roles with periodontal membrane, insolubilized properties of collagen as artificial periodontal nembrane were examined.Apatite-collagen composites coated with artificial membrane and irradiated by Plasma and UV-ray showed good biocompatibility in rat. However, since mechanical properties of the composites and artificial periodontal membrane were not enough to apply, further investigations are in progress.
