摘要：
PURPOSE: A dental photopolymerizable temporary filling composition is provided to ensure low polymerization contraction percentage and excellent mechanical property. CONSTITUTION: A dental photopolymerizable temperary filling composition contains: 41 weight parts of an organic mixture； 8-12 weight parts of hydroxyethyl methacrylate as a diluents, 4-6 weight parts of nanosilica as a thickening agent, 40-42 weight parts of barium glass as a filling agent, 1-3 weight parts of 4-(N,N-dimethyl amino)benzoate, and 0.05-0.15 weight parts of butylhydroxy toluene as an anti-oxidant, and 0.05-0.15 weight parts of UV stabilizing agent.본 발명은 치아용 광중합성 임시충전재 조성물에 관한 것으로, 더욱 상세하게는 유기혼합물, 희석제인 히드록시에틸메타아크릴레이트, 증점제인 나노실리카, 충전제인 바륨유리, 광증감제, 개시제인 4-(N,N-디메틸아미노)벤조에이트, 산화방지제인 부틸히드록시톨루엔 및 자외선안정제를 포함하여 이루어진다.전술한 치아용 광중합성 임시충전재 조성물은 유기혼합물로 1,1,1-트리스[4-(2-메타크릴로록시-3-메타크릴로록시)페닐]에탄이 사용되어 낮은 중합수축율과 우수한 기계적 물성을 나타낸다.
