There is little evidence of the effect of implants restored with fixed partial dentures on oral health-related quality of life (OHRQoL) in partially edentulous Kennedy class II and III patients. The aim of this study was to determine the change in OHRQoL in Kennedy classification II and III patients treated with a two-implant-supported fixed dental prosthesis (FDP). Kennedy class II and III patients received dental implants and an FDP. Oral health-related quality of life was measured by administration of the Oral Health Impact Profile-14 (OHIP-14NL) questionnaire at intake (T1), 2 weeks after surgery (T2) and after 1 year of loading (T3). The mean OHIP score at T1 was 6·5 ± 1·2, 2·4 ± 1·0 at T2, and 0·9 ± 0·3 at T3. There was a statistically significant difference between T1 and T2 (P = 0·002) and T1 and T3 (P < 0·001) but not between T2 and T3 (P = 0·407). The OHIP score in Kennedy II patients decreased from 4·8 ± 3·2 at T1 to 1·5 ± 2·0 at T2 and 1·1 ± 1·8 at T3, and that in Kennedy III patients decreased from 8·9 ± 9·6 at T1 to 3·6 ± 8·9 at T2 and 0·8 ± 2·2 at T3. There were no statistically significant differences in the reductions in Kennedy II and III patients. Oral health-related quality of life changed positively in patients treated with implants and an FDP in both groups. There was no change in OHRQoL between the times of implant placement and FDP placement.
在部分牙列缺损的肯尼迪II类和III类患者中，关于固定局部义齿修复种植体对口腔健康相关生活质量（OHRQoL）影响的证据很少。本研究的目的是确定接受两颗种植体支持的固定义齿（FDP）治疗的肯尼迪分类II类和III类患者的OHRQoL变化。肯尼迪II类和III类患者接受了牙种植体和FDP。通过在基线（T1）、术后2周（T2）和加载1年后（T3）发放口腔健康影响程度量表-14（OHIP-14NL）问卷来测量口腔健康相关生活质量。T1时OHIP平均得分是6.5±1.2，T2时是2.4±1.0，T3时是0.9±0.3。T1和T2之间（P = 0.002）以及T1和T3之间（P < 0.001）存在统计学显著差异，但T2和T3之间没有（P = 0.407）。肯尼迪II类患者的OHIP得分从T1时的4.8±3.2降至T2时的1.5±2.0以及T3时的1.1±1.8，肯尼迪III类患者的得分从T1时的8.9±9.6降至T2时的3.6±8.9以及T3时的0.8±2.2。肯尼迪II类和III类患者的得分降低没有统计学显著差异。两组接受种植体和FDP治疗的患者口腔健康相关生活质量均呈正向变化。种植体植入和FDP放置时间之间OHRQoL没有变化。
