| ［摘要］ 目的 比较氧化锆全瓷冠与全锆冠在后牙固定修复中的临床综合修复效果。方法 36例后牙缺失需修复的患者，其中19例66颗牙行氧化锆全瓷冠桥修复，17例60颗牙行氧化锆全锆冠桥修复。追踪观察1～3年，由修复科医师对义齿的边缘适合性、牙龈健康情况、牙冠外形、色泽、是否崩瓷、破裂等进行评价。结果 两组病例修复效果在所检查的指标中比较差异均无统计学意义（P>0.05）。结论 氧化锆全瓷冠与全锆冠在边缘密合性、美观性及抗折强度方面，均能满足临床要求。但在合龈距离较短的病例中，全锆冠的修复更具优势。 |

| Abstract: |
| ［Abstract］ Objective To compare the repairing effects between the zirconia all-ceramic crown bridge and zirconia bridge in aesthetics restoration of molars.Methods Thirty-six patients were restorated with the all-ceramic crown bridge(19 patients 66 molars) and zirconia(bridge 17 patients 60 molars), followed up for 1～3 years,checked and appraised the marginal adaptation,form,colour of the crowns,the gingiva and crown fracture by one doctor.Results There was no statistically difference in the effects between the two kinds of restorations.Conclusion The two kinds of restoration can meet clinical needs in the marginal adaptation，aesthetics and the flexural strength.The zirconia bridge is better in patients with shorter occlusogingival distance. |
