基于口内扫描仪和种植模板的数字化全口覆盖义齿的临床应用

Clinical Application of Digital Complete Overdenture Based on Intraoral Scanner and Implant Template

目的:探讨基于口内扫描仪和种植模板的数字化全口覆盖义齿的临床应用。方法:将2017年1月~2019年12月在我院口腔修复科进行治疗的牙列缺失患者64例随机分为对照组和实验组。对照组采用传统全口义齿修复法,实验组采用基于口内扫描仪和种植模板的数字化全口覆盖义齿修复。比较两组患者种植体成功率、种植体周围边缘骨吸收、种植体位置偏移以及义齿满意度的差异。结果:实验组患者种植成功率显著高于对照组,种植体周围边缘骨吸收低于对照组,实验组患者种植体肩部偏移、根部偏移、角度偏移、深度偏移均低于对照组,患者咀嚼功能、固定功能、舒适程度满意度均高于对照组,差异均具有统计学意义(P<0.05)。结论:基于口内扫描仪和种植模板的数字化全口覆盖义齿应用于牙列缺失患者,能够提高患者种植成功率,降低种植体周围边缘骨吸收、种植体位置偏移,改善患者义齿满意度,具有较高的临床应用价值。

Objective:To investigate the clinical application of digital complete overdenture based on intraoral scanner and implant template.Methods:A total of 64 patients from Jan 2017 to Dec 2019 were randomly divided into the control group and experimental group.The control group was treated with conventional complete d enture,while the experimental group was treated with digital complete overdenture based on intraoral scanner and implant template.The implant success rate,peri-implant marginal bone loss,implant position deviation,and denture satisfaction were compared between two groups.Results:The implant success rate in the experimental group was significantly higher than that in the control group,and peri-implant marginal bone loss was lower than that in t he control group(P<0.05).The apex deviation,neck deviation,angular deviation,and depth deviation in the observation group were all lower than those in the control group(P<0.05).The patients'satisfaction with masticatory function,fixed function,and comfort degree was higher than that of the control group(P<0.05).Conclusion:The application of digital complete overdenture based on intraoral scanner and implant template can improve the implant success rate,reduce the peri-implant marginal bone loss and implant position deviation,and improve the satisfaction of denture.
