Abstract

Objective

Digital workflows are increasingly used for fabricating metal frameworks of removable partial dentures (RPDs), offering advantages in clinical efficiency and reproducibility. This systematic review aimed to compare patient-reported outcome measures (PROMs) between conventionally and digitally fabricated RPDs.

Methods

An electronic and manual search was conducted up to January 1, 2025, to identify clinical trials and cohort studies evaluating PROMs for conventional and digital RPD frameworks. Studies using validated tools, including visual analogue scales (VAS) and oral health-related quality of life (OHRQoL) questionnaires, were included. Two reviewers independently performed study selection, data extraction, and quality assessment. Meta-analyses were conducted using weighted mean differences (WMD) or standardized mean differences (SMD) with 95 % confidence intervals (CIs), applying a random-effects model.

Results

Out of 942 identified studies, four met the inclusion criteria (59 patients, 118 RPDs), with three eligible for meta-analyses. Digitally fabricated RPDs showed significant improvements in speech (WMD = 1.01; 95 % CI: 0.03 to 1.99; p = 0.04), cleanability (WMD = 0.66; 95 % CI: 0.00 to 1.31; p = 0.05), and prosthesis stability (WMD = 1.24; 95 % CI: 0.01 to 2.46; p = 0.05). No significant differences were found in esthetic perception, overall satisfaction, or OHRQoL.

Conclusion

Digital workflows may improve specific aspects of patient comfort, particularly speech, hygiene, and stability, but offer similar outcomes to conventional methods in terms of satisfaction and esthetic perception.

Clinical Significance

Digitally fabricated RPD frameworks may improve patient comfort by enhancing speech clarity, hygiene maintenance, and prosthesis stability. These benefits can support better long-term outcomes and reduced clinical chair time, suggesting that digital workflows represent a reliable and efficient alternative to conventional fabrication methods.

数字与传统制造框架在可移动局部义齿中患者报告的结果：系统回顾和荟萃分析。

目的：数字化工作流程越来越多地应用于可摘局部义齿金属支架的制作，在临床效率和可重复性方面具有优势。本系统综述旨在比较传统和数字制作rpd之间的患者报告结果（PROMs）。方法：截至2025年1月1日，进行了电子和手动检索，以确定评估传统和数字RPD框架中PROMs的临床试验和队列研究。纳入了使用经过验证的工具的研究，包括视觉模拟量表（VAS）和口腔健康相关生活质量问卷（OHRQoL）。两名审稿人独立进行研究选择、数据提取和质量评估。采用随机效应模型，采用加权平均差异（WMD）或标准化平均差异（SMD）， 95%置信区间（CIs）进行meta分析。结果：在942项确定的研究中，4项符合纳入标准（59例患者，118例rpd）， 3项符合meta分析。数字制作的rpd表现出显著的语音改善(WMD = 1.01；95% CI: 0.03 ~ 1.99；p = 0.04)，清洁度(WMD = 0.66；95% CI: 0.00 ~ 1.31；p = 0.05)，假体稳定性(WMD = 1.24；95% CI: 0.01 ~ 2.46； = 0.05页)。在审美知觉、总体满意度和OHRQoL方面没有发现显著差异。结论：数字化工作流程可以改善患者舒适度的特定方面，特别是言语、卫生和稳定性，但在满意度和美感方面与传统方法提供相似的结果。临床意义：数字制造的RPD框架可以通过提高语音清晰度、卫生维护和假体稳定性来改善患者的舒适度。这些优点可以支持更好的长期结果，减少临床主持时间，表明数字工作流程是传统制造方法的可靠和有效的替代方案。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
