摘　　要：目的:测量金沉积烤瓷冠的边缘浮出量及粘固剂的厚度,并与镍铬合金烤瓷冠相比较,为金沉积烤瓷冠的临床应用提供适合性方面的理论依据。方法:用片切法测量两组全冠粘固前、后边缘浮出量及粘固剂的厚度。结果:金沉积烤瓷冠粘固前、后的边缘浮出量分别为(26.32±9.61)μm、(48.31±14.25)μm,粘固剂厚度为(38.15±14.32)μm,与镍铬合金烤瓷冠相比较差异有统计学意义(P>0.05);两组全冠粘固前和粘固后的边缘浮出量差异有统计学意义(P>0.05)。结论:金沉积烤瓷冠适合性明显优于镍铬合金烤瓷冠;粘接对全冠修复体的边缘浮出量有影响。Objective：To measure the marginal opening of porcelain-fused-to-galvanized-gold crown and thickness of cement,compare these indexes between porcelain-fused-to-galvanized-gold crown and Ni-Cr alloy veramic crown,and provide theoretical evidence for clinic application of porcelain-fused-to-galvanized-gold crown. Methods： Measured the anterior and posterior marginal opening and thickness of cement with slicing method. Results： The anterior and posterior marginal opening of porcelain-fused-to-galvanized-gold crown were （26.32±9.61）μm and （48.31±14.25）μm, respectively, the thickness was （38. 15±14.32）μm, with significant difference compared with Ni-Cr alloy veramic crown （ P 〈 0.05 ）. Conclusion ： The suitability of porcelain-fused- to-galvanized-gold crown is more satisfactory than Ni-Cr alloy veramic crown. And the cement has effect on marginal opening.
