Digital workflows for digital complete denture fabrication have a variety of clinical and laboratory procedures, but their outcomes and associated complications are currently unknown.
The purpose of this systematic review was to evaluate the clinical and laboratory procedures for digital complete dentures, their outcomes, and associated complications.
Electronic literature searches were conducted on PubMed/Medline, Embase, and Web of Science for studies published from January 2000 to September 2022 and screened by 2 independent reviewers. Information on digital complete denture procedures, materials, their outcomes, and associated complications was extracted.
Of 266 screened studies, 39 studies were included. While 26 assessed definitive complete dentures, 7 studies assessed denture bases, 2 assessed trial dentures, and 4 assessed the digital images only. Twenty-four studies used border molded impression technique, 3 studies used a facebow record, and 7 studies used gothic arch tracing. Only 13 studies performed trial denture placement. Twenty-one studies used milling, and 17 studies used 3D printing for denture fabrication. One study reported that the retention of maxillary denture bases fabricated from a border-molded impression (14.5 to 16.1 N) was statistically higher than the retention of those fabricated from intraoral scanning (6.2 to 6.6 N). The maximum occlusal force of digital complete denture wearers was similar across different fabrication procedures. When compared with the conventional workflow, digital complete dentures required statistically shorter clinical time with 205 to 233 minutes saved. Up to 37.5% of participants reported loss of retention and up to 31.3% required a denture remake. In general, ≥1 extra visit and 1 to 4 unscheduled follow-up visits were needed. The outcomes for patient satisfaction and oral health-related quality of life were similar between conventional, milled, and 3D printed complete dentures.
Making a border-molded impression is still preferred for better retention, and trial denture placement is still recommended to optimize the fabrication of definitive digital complete dentures.
数字化全口义齿制作的数字化工作流程有多种临床和实验室程序，但它们的结果和相关并发症目前尚不清楚。
本系统评价的目的是评估数字化全口义齿的临床和实验室程序、结果和相关并发症。
对 PubMed/Medline、Embase 和 Web of Science 进行电子文献检索，检索时间为 2000 年 1 月至 2022 年 9 月，由 2 名独立评审员进行筛选。提取有关数字化全口义齿程序、材料、结果和相关并发症的信息。
在 266 篇筛选出的研究中，有 39 篇被纳入。其中 26 篇评估了最终全口义齿，7 篇评估了义齿基托，2 篇评估了试戴义齿，4 篇仅评估了数字图像。24 篇研究使用边缘压模印模技术，3 篇研究使用面弓记录，7 篇研究使用哥特式弓描记。仅有 13 篇研究进行了试戴义齿放置。21 篇研究使用铣削，17 篇研究使用 3D 打印制作义齿。一项研究报告称，从边缘压模印模（14.5 至 16.1 N）制作的上颌义齿基托的保留力明显高于从口内扫描（6.2 至 6.6 N）制作的保留力。使用不同制作程序的数字化全口义齿佩戴者的最大咬合力相似。与传统工作流程相比，数字化全口义齿的临床时间可节省 205 至 233 分钟。高达 37.5%的参与者报告说保留力丧失，高达 31.3%的人需要重新制作义齿。一般来说，需要额外的 1 至 4 次预约和 1 至 4 次非计划性随访。常规、铣削和 3D 打印全口义齿的患者满意度和口腔健康相关生活质量的结果相似。
为了更好的保留力，仍然首选制作边缘压模印模，并且仍然建议进行试戴义齿放置，以优化最终数字化全口义齿的制作。
