我们研究了非金属卡环义齿（NMCDs）在口腔健康相关生活质量（OHRQoL）方面的疗效，并将结果与传统金属卡环保留义齿（MCDs）的结果进行了比较。这项单中心、随机对照、两期、开放标签、交叉试验包括28名部分齿状体个体。患者被随机分配接受mcd和nmcd，或相反的顺序（每组n = 14）；每个义齿佩戴3个月。在入组（t -入组；使用第一副义齿治疗前）和使用每副义齿治疗后3个月（T3）时，使用口腔健康影响量表-日本版（o嘻哈- j）对OHRQoL进行评估。检查员在假牙交付前（T0）和T3时评估假牙稳定性、口腔外观和表面粗糙度，并在T3时评估假牙卫生。共有24名患者完成了试验。两种义齿随访期间均未发生与义齿、基牙及义齿承托黏膜相关的并发症。nmcd的平均OHIP综合评分低于mcd，差异（9分）大于最小重要差异（6分），表明差异具有临床相关性。效应量为中等（070）。采用线性混合模型进行统计分析发现，假牙类型对OHIP综合评分、口腔-面部外观评分、口腔-面部疼痛评分和心理影响域评分有显著影响（NMCD < MCD; P < 005）。我们的研究结果表明，与mcd相比，nmcd可以提供更好的OHRQoL。
We investigated the efficacy of non-metal clasp dentures (NMCDs) with regard to the oral health-related quality of life (OHRQoL) and compare the findings with those for conventional metal clasp-retained dentures (MCDs). This single-centre, randomised controlled, two-phase, open label, cross-over trial included 28 partially dentate individuals. The patients were randomised to receive MCDs followed by NMCDs, or the opposite sequence (n = 14 in each group); each denture was worn for 3 months. OHRQoL was evaluated using the Oral Health Impact Profile-Japanese version (OHIP-J) at entry (T-entry; before treatment with the first denture) and at 3 months after treatment with each denture (T3). An examiner evaluated denture stability, oral appearance and surface roughness before denture delivery (T0) and at T3 and denture hygiene at T3. A total of 24 patients completed the trial. There were no complications related to the dentures, abutment teeth or denture-bearing mucosa during the follow-up periods for both dentures. The mean OHIP summary score was lower for NMCDs than for MCDs, and the difference (9 points) was greater than the minimal important difference (6 points), indicating the difference was clinically relevant. The effect size was medium (070). Statistical analyses with linear mixed models found a significant effect of the denture type on the OHIP summary score and scores for the Oro-facial appearance, Oro-facial pain and Psychological impact domains (NMCD < MCD; P < 005). The results of our study suggest that NMCDs allow for better OHRQoL compared with MCDs.
