BACKGROUND: Patient subjective satisfaction is of great significance for the clinical use of implant denture.OBJECTIVE: To investigate the patient satisfaction with single or bridge crown for repair of consecutive missing posterior teeth in the maxilla.METHODS: We selected 203 patients with consecutive missing of maxillary first and second molar teeth, who had received single (n=99) or bridge (n=104) crown for implant restoration 1 year ago. All patients were surveyed with a subjective satisfaction questionnaire and visual analogue scale.RESULTS AND CONCLUSION: There was no significant difference in sex and age (35-64 years) between the two groups. Food impaction ratio and crown off ratio were higher in the bridge crown group than the single crown group.Noticeably, most patients did not have the habit of using dental floss. The overall satisfaction scores were 88.96% in the single crown group and 85.32% in the bridge crown group, respectively. Four indexes with less than 80 scores in the two groups were that "I dare to use the implant teeth to bite hard food", "my implant teeth are easily cleaned", "it takes me less time to clean my implant teeth than natural teeth", and "I think the dental implant price is acceptable". Results from the analysis of variance showed that food impaction influenced chewing effect (P=0.047), made the use of dental floss difficult (P=0.031), made patients discomfort (P=0.038), and the use of dental floss could enhance the cleaning effect on dental implant (P=0.019), and largely reduced brushing bleeding (P=0.029). In conclusion, patients with missing maxillary posterior teeth can obtain higher satisfaction after single crown or bridge crown repair. However, food impaction and crown off become more serious after repair with bridge crown, while the repair with single crown exhibits better performance.%背景:患者对种植义齿修复的满意度在种植义齿的临床推广中具有重要意义.目的:调查上颌后牙连续缺失患者对连续单冠与连冠种植修复后的主观满意度.方法:选择203例采取连续单冠与连冠粘接固位种植修复1年的上颌第一二磨牙连续缺失患者,其中单冠修复者99例,连冠修复者104例,进行目测类比评分主观满意度问卷调查.结果与结论:①选择单冠组与连冠修复组的男女比例差异不大,年龄多分布35-64岁,连冠修复组食物嵌塞比例、连冠修复脱落比例大于单冠修复组,大部分患者没有使用牙线的习惯;②单冠修复组、连冠修复组总体满意度分别为88.96%和85.32%,两组低于80的4项指标均为:我敢用种植牙咬硬食物、我的种植牙容易被清洁、我的种植牙和天然牙相比需要更少时间清洁、我觉得种植牙价格合适可以接受;③方差分析结果显示,食物嵌塞会影响咀嚼效果(P=0.047)、会使种植牙清洁工作变得困难(P=0.031)、会使患者感到不适(P=0.038),使用牙线可增强种植牙清洁效果(P=0.019)、大幅度减小刷牙出血问题(P=0.029);④结果表明,上颌后牙缺失患者采用单冠与连冠种植修复均可获得较高满意度;连冠修复组患者出现食物嵌塞现象更严重;连冠修复出现冠脱落现象更严重,单冠修复表现出更加优良的特性.
