摘要
目的:探讨瓷沉积冠的临床应用效果。方法:分别制作镍铬合金烤瓷冠、高金合金烤瓷冠、铸瓷冠及瓷沉积冠各30件。用Easyshade电脑比色仪检测4种烤瓷冠的颜色,临床检查烤瓷冠的边缘密合度,冠的颜色以及瓷崩瓷裂情况,观察时间为18个月。结果:瓷沉积冠、铸瓷冠及高金合金烤瓷冠的边缘密合度一致,均明显优于镍铬合金烤瓷冠(P<0.05);瓷沉积冠、铸瓷冠的颜色基本一致,比高金合金烤瓷冠更接近天然牙,但无统计学差异(P>0.05);瓷沉积冠、铸瓷冠及高金合金烤瓷冠的颜色均较镍铬合金烤瓷冠更接近天然牙,有统计学差异(P<0.05);四者在瓷崩瓷裂方面的差异无显著性。结论:瓷沉积冠颜色美观,边缘密合性良好,抗折力良好,具有临床推广价值。
Objective： To evaluate the effects of Electro layered Ceramic crown in clinic. Methods： The Ni-Cr alloy, high gold alloy, Emprss-Ⅱ ceramic crown and Electro layered Ceramic crown were made respectively. Every kind was 30 pieces. The eolour of ceramic crowns was checked with Easy Shade. The colour, fitness and fracture of ceramic crowns were checked in clinic. Results： The results showed Electro layered Ceramic crowns were similar to Emprss- II ceramic crowns and high gold alloy ceramic crowns in fitness in clinic. They are better than Ni-Cr alloy ceramic crowns significantly. The electro layered ceramic crowns are similar to Emprss- II ceramic crowns in colour. They are better than high gold alloy ceramic crowns in colour, but it is no statisitical meaning. （P〉0.05）; one of three was better than Ni-Cr alloy ceramic crowns in colour obviously. （P〈0.05）. The fracture of 120 ceramic crowns was not found out in 18 months. Conclusions： The effects of electro layered ceramic crowns were perfect in colour, fitness and fracture. It can be used in clinic.
