摘　　要：【目的】比较四种材料制成的冠修复体修复上颌前牙的临床应用效果。【方法】从修复体颜色,冠边缘适合性,颈缘着色,修复体折裂和牙龈健康状况等五个方面对修复效果进行比较评价。【结果】金沉积瓷冠和泽康氧化锆全瓷冠在各个方面均优于镍铬和钴铬烤瓷冠。【结论】金沉积瓷冠和泽康氧化锆全瓷冠是上颌前牙的理想修复方式,而钴铬合金烤瓷冠优于镍铬合金烤瓷冠。[Objective] To compare the effect of crown made by 4 different kinds material in resteration of maxillary anterior tooth. [ Methods ] The effect was evaluated by the following indices including color, marginal adaptation, gingival border stain,fracture of the crown and status of the gingival. [ Results] Galvanized forming ceramic crown and Cercon all-ceramic crown were better than Ni-Cr alloy ceramic crown and Co-Cr alloy ceramic crown in all aspects. [Conclusion] Galvanized forming ceramic crown and Cercon all-ceramic crown are favorable choice to restore the maxillary anterior tooth,and the Co-Cr alloy ceramic crown is better than Ni-Cr alloy ceramic crown.
