Since light curing composite resin was introduced in the 1960s, light curing process has been considered as an essential process. Herein, various light sources became available for the process. Quartz-tungsten-halogen (QTH) light curing units (LCUs) dominated the market until the 1990s, before the L...

광중합 레진의 중합 개시제로 주로 사용되는 물질은 무엇인가? | 1960년대 후반 광중합 레진이 소개된 이후 레진은 구강내 환경에서 안정적으로 유지되며, 환자들의 심미적 요구의 증대로 현재 가장 널리 사용되고 있는 수복재료이다. 광중합 레진의 중합 개시제로는 camphoroquinone(CQ)과 삼차 아민이 주로 사용되며 레진이 적절히 잘 중합되기 위해서 광중합기는 중요하며 이에 따라 중합기에 대한 많은 연구들이 진행되고 있다.1,2 | |
1세대 광중합기란 무엇인가? | 2000년에 들어와 LED 광중합기가 시장에 처음으로 출시되었다. 1세대 광중합기는 여러 개의 LED가 합쳐져서 출력을 내는 중합기들이다.1,2 처음 시판된 LED광중합기는 LuXoMAX (Akeda Dental A/S, Lystrup,Denmark)라는 제품으로 7개의 LED가 합쳐져 있으며, 충전식으로 휴대가 가능하였다. | |
QTH 중합기의 단점은 무엇인가? | 처음 소개된 광중합기에서 발전하여 Quartz-tungsten-halogen (QTH) 중합기가 1990년대까지 널리 사용되었다. 하지만, 크고 휴대하기가 불편한 단점을 가지고 있다. |
