应用OHIP-14评价Locator附着式种植覆盖义齿患者口腔健康相关生活质量的研究

目的:评价无牙颌患者接受Locator附着式种植覆盖义齿修复前、后口腔健康相关生活质量的变化。方法:选取2016-2017年在天津市口腔医院种植中心接受Locator附着式种植覆盖义齿修复的患者30例（实验组），分别于植体植入治疗前1周（T1）、覆盖义齿修复完成后3个月（T2）填写口腔健康影响程度量表（OHIP-14），同期选取30例牙列完整的健康志愿者作为对照组，均填写OHIP-14。结果:实验组T2时点各项评分均显著低于T1时点,差异有统计学意义（P<0.05），T2时点口腔功能限制、生理障碍、心理障碍得分高于对照组，差异有统计学意义（P<0.05）。生理性疼痛、心理不适、社交障碍、残障项评分与对照组比较差异无统计学意义（P>0.05）。结论:无牙颌患者通过Locator附着式种植覆盖义齿修复可改善心理健康，提高生活质量；OHIP-14可客观评价无牙颌患者Locator附着式种植覆盖义齿修复前、后口腔健康相关生活质量的变化。

Evaluation of oral health-related life quality in Locator implant-supported overdenture patients by oral health impact scale (OHIP-14)

Objective: To evaluate the changes of oral health-related life quality of edentulous patients before and after implant-supported overdenture with Locator attachment. Methods: 30 cases with Locator implant-supported overdenture selected as experimental group were evaluated by oral health impact scale (OHIP-14) in Tianjin Stomatological Hospital Center from 2016 to 2017, respectively 1 week prior to the implant treatment (T1), 3 months after overdenture rehabilitation (T2). Meanwhile, 30 healthy volunteers selected as control group were evaluated with oral health impact scale (OHIP-14). Results: The scores of the experimental group at T2 point were significantly lower than those at T1 point(P<0.05). The scores of oral function limitation, physiological disorder and psychological disorder at T2 point in experimental group were higher than those in the control group(P<0.05). There was no significant difference in the scores of physical pain, psychological discomfort, social disorder and disability between the two groups (P>0.05). Conclusion: Locator attachment implant overdenture can improve health and life quality of edentulous patients. Oral health impact scale(OHIP-14) can objectively evaluate the changes of oral health-related life quality of edentulous patients before and after Locator attachment implant overdenture restoration.
