Abstract

The fiber-reinforced endodontic posts were prepared using a photocurable resin and a glass fiber. The mechanical property of the posts increased with increasing density of glass fiber and the micro-pores in the post were removed by a vacuum impregnation process. To improve the interfacial adhesion between glass fiber and polymer, silane coupling agent was used. The surface treatment of glass fiber increased the surface wettability of resing on glass fiber and increased the adhesion property with resin, consequently improved the mechanical property of posts.

근관 치료를 위해 사용되는 섬유 강화형 포스트를 광중합 레진과 유리섬유를 이용하여 제조하였다. 제조된 포스트는 유리 섬유의 밀도가 높아짐에 따라 기계적 특성이 향상됨을 확인 할 수 있었고 광중합 레진의 점도 조절 및 진공함침 공정을 통해 미세 기공을 효과적으로 제거 할 수 있었다. 유리섬유와 광중합 레진과의 계면 결합력을 향상시키기 위해 유리 섬유 표면을 실란 커플링제를 사용하여 표면처리를 하였으며, 유리섬유의 표면처리는 유리 섬유 표면에 레진의 젖음성을 향상시켜 레진과의 결합 특성을 향상시키고 포스트의 기계적 특성을 향상시킴을 확인할 수 있었다.
