前牙金沉积烤瓷冠的临床效果评价

The Application of Auro-galvano-form Ceramic Crowns in Clinic.

目的 探讨金沉积烤瓷全冠的临床应用效果。方法 分别制作铸造镍铬合金、铸造高金合金与金沉积烤瓷冠各50件。临床检查烤瓷冠的边缘密合度、冠的颜色、颈缘染色以及有无折裂和崩瓷等情况,观察时间为18个月。结果金沉积烤瓷冠与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<0.01);金沉积烤瓷冠与高金合金烤瓷冠的颜色基本相似,均较镍铬合金烤瓷冠更接近天然牙(P<0.01);三者在折裂、崩瓷方面无差异。结论 金沉积烤瓷冠在颜色方面显示出优势,有良好的边缘密合度和抗折强度,较高的患者满意度,具有临床推广价值。

Objective To evaluate the effects of anterior auro-galvano-form ceramic crown in clinic. Methods The Ni-Cr alloy, high-gold alloy and auro-galvano-form ceramic crowns were made respectively. Every kind was 50 pieces. 150 piece crowns were in total for 32 patients. The color, fitness and fracture of ceramic crowns were checked in clinic. Results The results showed the auro-galvanoform ceramic crowns was similar to high-gold alloy ceramic crowns in color and fitness (P>0.05). The effects of them were better than Ni-Cr alloy ceramic crowns in color and fitness significantly(P<0.01). The fracture of 150 ceramic crowns was not found out in 18 months. Conclusion The effect of auro-galvano-form ceramic crowns were perfect in color, fitness and fracture. It can be used in clinic
