活动义齿和固定义齿在牙周病伴牙列缺损修复中的应用研究

摘要

目的：探讨牙周病（PD）伴牙列缺损应用活动义齿和固定义齿修复的临床效果。方法选取我院2012年1月~2014年6月收治的66例PD伴牙列缺损患者，根据数字随机表法均分为两组。对照组：行活动义齿修复，观察组：采取固定义齿修复。记录比较两组修复6个月时满意度总评分，修复前后龈沟出血指数（SBI）、口腔健康影响程度量表(OHIP-14)中文版总评分及咀嚼效率。结果修复6个月时，观察组满意度总评分为（20.56±3.14）分，显著高于对照组的（18.21±2.83）分（P<0.01）；与修复前相比，修复1年时两组SBI均显著下降（P<0.01），但对照组降低幅度更为显著（P<0.01）；与修复前比较，修复1年、2年时两组OHIP-14总评分均显著降低（P<0.01），且观察组下降程度更为显著（P<0.01）；修复后1年~2年期间，观察组OHIP-14总评分上升幅度显著低于对照组（P<0.01）；两组修复1年、2年时咀嚼效率与修复前比较，均显著提高（P<0.01），且观察组上升幅度更为显著（P<0.01）；修复后1年~2年期间，观察组咀嚼效率下降程度显著低于对照组（P<0.01）。结论 PD伴牙列缺损采取固定义齿修复更有助于提高患者综合满意度、生活质量及咀嚼功能，疗效切实且稳定，故在满足有关适应证前提下，应优先选取固定义齿修复。%Objective To investigate the clinical effect of application of removable partial denture and fixed partial denture in the repair of periodontal disease (PD) with dentition defect. Methods 66 cases of PD patients with dentition defect treated in our hospital from January 2012 to June 2014 were selected and divided into two groups according to the method of random digital table. The control group adopted removable partial denture repair, while the observation group took fixed partial denture restoration. The total scores of satisfaction rate, sulcus bleeding index(SBI), oral health impact degree scale(OHIP-14), and the chewing efficiency after 6 months of restoration were recorded and compared between the two groups. Results In the 6 months of restoration, the total score of satisfaction rate in the observation group was (20.56 ±3.14), which was significantly higher than (18.21 ±2.83) of the control group (P<0.01);Compared with the previous repair, in the 1 year of restoration, SBI of the two groups significantly decreased (P<0.01), but the decreased degree of the control group was more significant (P<0.01); the total score of OHIP-14 in the two groups in the 1 year, 2 years of restoration was significantly lower than those before the repair (P<0.01), and the declined degree of the observation group was more significant (P<0.01); during the 1 year to 2 years after repair, the total score of OHIP-14 in the observation group was significantly lower than that of the control group (P<0.01); after 1 year, 2 years of repair, the chewing efficiency of the two groups significantly improved compared with that before the repair (P<0.01), and the improved degree of the observation group was more significant (P<0.01); during 1 year to 2 years after repair, the declined degree in chewing efficiency of the observation group was significantly lower than that of the control group (P<0.01). Conclusion PD patients with dental dentition defect can take fixed partial denture repair, which is more useful to improve patients' comprehensive satisfaction, quality of life and masticatory function, with real and stable effect. Therefore, fixed partial denture repair should be taken first under the premise of meeting the relevant indications.
