Statement of problem

Studies on the impact of incorporating attachments in removable prostheses on patient-based outcomes are scarce.

Purpose

The purpose of this clinical study was to investigate oral health–related quality of life (OHRQoL) and patient satisfaction in partially edentulous participants before and after rehabilitation with mandibular attachment-retained removable prostheses as compared with conventional removable prostheses.

Material and methods

This crossover study included 74 participants (aged 36 to 57). Initially, 56 received conventional clasp-retained removable dental prostheses (RDPs), and 18 received conventional overdentures (ODs) based on their mandibular partially edentulous state. Two months later, of the 56 RDP participants, 24 had received extracoronal attachment-retained RDPs, 17 received telescope-retained RDPs, and 15 received bar-attachment retained RDPs. The 18 OD participants received ball attachment–retained ODs. Assessments included Oral Health Impact Profile-short version-14 for OHRQoL and a visual analog scale (VAS) for patient satisfaction. Assessments were done before treatment and 2 months after wearing each prosthesis with a 1-month washout period. Statistical analysis included the Friedman then the Wilcoxon signed rank test for Oral Health Impact Profile-short version-14 scores and repeated measures ANOVA then the Bonferroni or paired t test for VAS scores (α=.05).

Results

There were no dropouts. Rehabilitation, irrespective of prosthesis type, significantly improved OHRQoL in all domains and significantly increased overall patient satisfaction (P<.05). When compared with the conventional prostheses, attachment-retained prostheses significantly improved functional limitation, psychological discomfort, and physical limitation domains in all groups (P<.05), as well as the physical pain domain in the OD group (P=.041). General satisfaction, stability, comfort, ability to speak, and ability to masticate significantly increased (P<.05) with attachment-retained prostheses. Conventional prostheses were significantly easier to clean (P<.05) in all groups, except for the telescope-attachment group.

Conclusions

Both conventional and attachment-retained prostheses significantly increased patient satisfaction and improved OHRQoL in all domains as compared with before treatment. However, incorporation of attachments further improved functional limitation, psychological discomfort, and physical limitation domains in all groups, as well as the physical pain domain in the OD group. Participants were more satisfied with their attachment-retained prostheses in most aspects.

保留附件的可移动假体：患者满意度和生活质量评估

问题陈述

很少有关于将附件结合到可移动假体中对基于患者的结果的影响的研究。

目的

这项临床研究的目的是研究与常规可移动假体相比，使用下颌骨固定的可移动假体进行康复前后，部分无牙颌参与者的口腔健康相关的生活质量（OHRQoL）和患者满意度。

材料与方法

这项跨界研究包括74名参与者（年龄在36至57岁之间）。最初，有56位患者接受了传统的扣环固定式可移动义齿（RDP），有18位患者接受了基于其下颌部分无牙状态的常规覆盖义齿（OD）。两个月后，在56名RDP参与者中，有24名接受了冠状动脉附件保留的RDP，有17名接受了望远镜保留的RDP，还有15名接受了棒附件保留的RDP。18位OD参与者接受了保留球附着的OD。评估包括OHRQoL的口腔健康影响资料-短版14和患者满意度的视觉模拟量表（VAS）。评估是在治疗前和佩戴每个假体后2个月进行的，冲洗时间为1个月。t测试VAS分数（α= .05）。

结果

没有辍学。不论假体类型如何，康复治疗在所有领域均显着改善了OHRQoL，并显着提高了患者的总体满意度（P <.05）。与常规假体相比，保留附着物的假体在所有组中均显着改善了功能障碍，心理不适和身体限制域（P <.05），以及OD组的身体疼痛域（P = .041） 。保留附着物的假体可使总体满意度，稳定性，舒适度，说话能力和咀嚼能力显着提高（P <.05）。常规假体很容易清洗（P<.05）在所有组中，望远镜附件组除外。

结论

与治疗前相比，传统假体和保留附着物的假体在所有领域均显着提高了患者满意度并改善了OHRQoL。但是，附件的合并进一步改善了所有组的功能限制，心理不适和身体限制域，以及OD组的身体疼痛域。在大多数方面，参与者对保留附件的修复体更加满意。
