摘要 [目的]探索烧结次数对In-Ceram全瓷修复体体瓷抗压强度的影响。[方法]对Vita In-Ceram修复体体瓷进行烧结3次、5次、7次、9次的处理,在万能试验机上测试其抗压强度,并对破坏试验力值进行统计分析。[结果]烧结7次、9次的Vita In-Ceram体瓷比烧结3次、5次的抗压强度有较大降低,P<0.01差异有统计学意义。烧结7次和9次,3次和5次之间相比,P>0.01差异无统计学意义。[结论]超过一定的烧结次数时,烧结次数的增加对In-Ceram全瓷修复体强度有影响。7次以上烧结次数的In-Ceram全瓷修复体体瓷的抗压强度明显低于5次以下烧结次数In-Ceram全瓷修复体。技工室操作时应尽量减少对In-Ceram全瓷修复体体瓷的烧结次数,最好控制在7次以下。
