真空义齿修复上颌骨缺损中应用精密附件的效果评价

Evaluation of the Effect of Using Precision Attachments in Repairing Maxillary Defects with Vacuum Dentures

目的:探讨真空义齿修复上颌骨缺损中应用精密附件的效果。方法:选择2017年6月~2018年12月72例上颌骨缺损患者为观察对象,按修复方法不同将其分为两组各36例,观察组采取真空义齿联合球帽附着体修复,对照组采取可摘局部义齿修复。比较两组修复前后的咀嚼效率、语音清晰度及患者的主观评价。结果:两组修复后的咀嚼效率与语音清晰度均较修复前明显提高,且组间比较均无统计学意义(P>0.05)。观察组优良率为94.5%,对照组优良率为80.6%,组间比较具有统计学意义(P<0.05)。结论:上颌骨缺损患者采用真空义齿联合精密附件修复,可有效提高咀嚼和言语功能,并更容易被患者接受。

Objective:To explore the effect of using precision attachments in repairing maxillary defects with vacuum dentures.Methods:72 patients with maxillary defects were selected from June 2017 to December 2018,and they were divided into two groups of 36 patients according to different repair methods.The research group was repaired with vacuum denture combined with ball cap attachment,and the control group was removed.Partial denture repair.The chewing efficiency,speech intelligibility and subjective evaluation of patients before and after repair were compared between the two groups.Results:The chewing efficiency and speech intelligibility of the two groups after repair were significantly higher than before repair,and there was no statistical significance between the two groups(P>0.05).The excellent rate of the study group was 94.5%,and the good rate of the control group was 80.6%.The comparison between the groups was statistically significant(P<0.05).Conclusion:Vacuum denture combined with precision attachment repair in patients with maxillary defects can effectively improve chewing and speech function,and it is easier for patients to accept.
