摘　　要：目的探讨基牙折断后保留或拔除残根对可摘局部义齿添加人工牙效果的影响。方法对2011年6月至2013年3月郑州人民医院口腔科门诊收治的89例佩戴整体铸造支架式可摘局部义齿3~5年后基牙折断或脱落患者,行在旧义齿上添加人工牙的修复方式。89例患者随机分为两组：保留牙根组49例,保留牙根直接添加人工牙;无牙根组40例,拔除牙根后再添加人工牙。观察添加人工牙1年后的义齿固位力及稳定性、咀嚼功能、佩戴义齿舒适度、人工牙粘接等情况。结果两组患者的义齿固位力及稳定性比较差异无统计学意义（均P〉0.05）,佩戴义齿舒适度及人工牙粘接情况无牙根组优于保留牙根组（均P〈0.05）,保留牙根组牙龈炎发生率为24.5%、根面龋发生率为8%。结论基牙折断添加人工牙前拔除条件欠佳的残根,可以获得更好的义齿延期使用效果。Objective To explore the residual root on removable partial denture with artificial teeth. Methods A total of 89 cases of patients with removable partial denture with artificial teeth were divided into two groups ： a group with re- tained root added artificial teeth directly, another group with the root pulled outed. A year later, observe stability and re- tention of the dentures, chewing function, comfortable feding and bonding situation of artificial tooth. Results The re- tention force and stability had no statistically significant difference. The wearing comfort and bonding situation of artifi- cial teeth was better in root-removal group than in residual root group; the incidence of root caries and gingivitis in the re- sidual root group was 8% and 24.5%, respectively. Conclusion Adding artificial teeth after removing residual root can get better effect in use.
