采用刮除法测量不同光照距离对可见光固化复合树脂(VLAC)聚合深度的影响。VLAC 的聚合深度随照射距离的增大而减少,随照射时间延长而增加。适当延长照射时间,对增加聚合深度有一定作用。过多地延长照射时间,对聚合深度的增加则非常有限。
The influence of different illumination distance on the polymerization depth of visible light curable composite resin (VLAC) was measured by scratch-off method. The polymerization depth of VLAC decreases with the irradiation distance and increases with irradiation time. Appropriate to extend the irradiation time, to increase the depth of polymerization have a certain effect. Extending the exposure time too much increases the depth of polymerization very little.
