This study aimed to compare the clinical effectiveness and cost-efficiency of conventional and digital prosthodontic protocols, with a specific focus on milled and 3D-printed digital removable complete dentures.
This retrospective clinical study was conducted at the Removable Prosthodontics Department of the University of Siena. 60 patients were divided into two groups: 30 received conventional complete dentures, while the remaining 30 received digital complete dentures (15 milled and 15 3D-printed). Clinical outcomes were assessed using OHIP-14, bite force measurements, and masticatory performance tests before and six months after treatment. Treatment-related metrics, including chairside time, follow-up time, and laboratory costs, were recorded and compared across the groups. Statistical analysis was performed to determine the significance of differences between conventional and digital complete dentures, as well as between milled and 3D-printed digital complete dentures.
The study revealed that digital complete dentures significantly reduced chairside time compared to conventional dentures, with average times of 154.31 ± 13.19 min for digital dentures and 218.00 ± 20.75 min for conventional dentures (p < 0.0001). Laboratory costs were found to be statistically lower for digital dentures, (€378.79 ± 137.46 vs. €459.15 ± 63.72, p = 0.0059) compared to conventional dentures. No statistically significant differences were observed in bite force or masticatory performance between the groups. OHIP-14 scores indicated slightly lower patient satisfaction with digital dentures, but the difference was not clinically significant.
Digital removable dentures, including both milled and 3D-printed models, offer a practical and efficient alternative to conventional dentures, particularly in terms of reducing chairside time and laboratory costs.
Digital removable dentures offer a practical and efficient alternative to conventional dentures, particularly in terms of reducing chairside time and costs. These simplified digital protocols could be applied in residential facilities or within national healthcare programs, improving access to prosthetic care for a larger number of patients.
本研究旨在比较传统和数字化义齿修复方案的临床效果和成本效益，特别关注铣削和3D打印的数字化可摘全口义齿。
本回顾性临床研究在锡耶纳大学可摘义齿修复科进行。60例患者分为两组：30例接受传统全口义齿，其余30例接受数字化全口义齿（15例铣削和15例3D打印）。在治疗前和治疗后6个月，使用OHIP-14、咬合力测量和咀嚼性能测试评估临床结果。记录并比较各组与治疗相关的指标，包括椅旁时间、随访时间和实验室成本。进行统计分析以确定传统和数字化全口义齿之间以及铣削和3D打印数字化全口义齿之间差异的显著性。
研究表明，与传统义齿相比，数字化全口义齿显著减少了椅旁时间，数字化义齿的平均时间为154.31±13.19分钟，传统义齿为218.00±20.75分钟（p<0.0001）。与传统义齿相比，数字化义齿的实验室成本在统计学上更低（378.79±137.46欧元对459.15±63.72欧元，p = 0.0059）。各组之间在咬合力或咀嚼性能方面未观察到统计学上的显著差异。OHIP-14评分表明患者对数字化义齿的满意度略低，但差异无临床意义。
包括铣削和3D打印模型在内的数字化可摘义齿为传统义齿提供了一种实用且高效的替代方案，特别是在减少椅旁时间和实验室成本方面。
数字化可摘义齿为传统义齿提供了一种实用且高效的替代方案，特别是在减少椅旁时间和成本方面。这些简化的数字化方案可应用于住宅设施或国家医疗保健计划中，改善更多患者获得修复治疗的机会。
