Abstract：
Purpose Implant-assisted removable partial dentures (IARPDs) with short implants improve the oral functions of removable partial dentures (RPDs). This study aimed to compare the patient-reported outcomes of RPDs and IARPDs with short implants retained by magnetic attachments.Methods We recruited 30 participants with mandibular Kennedy Class I or II and distal extension defects of three or more teeth. RPDs, IARPDs with a healing cap, and IARPDs with a magnetic attachment were evaluated across stages using patient-reported outcomes. All participants completed questionnaires (oral health-related quality of life [OHRQoL], patient general satisfaction, and patient\'s denture assessment [PDA]) at each stage. The OHRQoL was evaluated using the Oral Health Impact Profile-J 54 (OHIP-J 54) score. The general patient satisfaction was evaluated using a 100 mm visual analog scale. The Wilcoxon signed-rank test and Bonferroni correction were used to evaluate differences between the groups (α=0.05).Results The OHRQoL of IARPDs was significantly higher than that of RPDs. IARPDs with a magnetic attachment had significantly better patient general satisfaction and PDA than IARPDs with a healing cap.Conclusions The OHRQoL, patient general satisfaction, and PDA were improved by IARPD with a short implant using a magnetic attachment.
摘要：
目的：采用短种植体的种植体辅助可摘局部义齿（IARPDs）改善可摘局部义齿（RPDs）的口腔功能。这项研究旨在比较RPDs和IARPDs与磁性附件保留的短植入物的患者报告结果。方法我们招募了30名下颌KennedyI级或II级以及三颗或更多颗牙齿的远端延伸缺损的参与者。RPD,带有治疗帽的IARPD，使用患者报告的结局对带有磁性附件的IARPD和IARPD进行了分期评估.所有参与者完成问卷（口腔健康相关生活质量[OHRQoL]，患者总体满意度,和患者义齿评估[PDA])在每个阶段。使用口腔健康影响概况-J54(OHIP-J54)评分评估OHRQoL。使用100mm视觉模拟量表评估患者的总体满意度。使用Wilcoxon符号秩检验和Bonferroni校正来评估组间差异（α=0.05）。结果IARPDs的OHRQoL明显高于RPDs。具有磁性附件的IARPD比具有愈合帽的IARPD具有更好的患者总体满意度和PDA。结论OHRQoL，患者总体满意度,IARPD通过使用磁性附件的短植入物改善了PDA。
