Abstract

Research question

Adhesion between the base and artificial teeth in 3D-printed prostheses is limited by physicochemical disparities, which may compromise bond strength and lead to failure. Developing strategies to enhance this adhesion is crucial to improve mechanical performance and clinical success of digitally fabricated prostheses. The research question was: How effective are different surface treatments in improving the bond strength between prefabricated and 3D-printed denture teeth and denture base resins compared to conventional denture base resins?

Material and methods

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was registered at osf.io/mqncf. Literature searches were conducted across five databases (PubMed, Embase, ScienceDirect, Web of Science, Scopus) and two sources of non-peer-reviewed literature (Google Scholar and ProQuest). The RoBDEMAT tool was applied to assess the risk of bias in the included studies.

Results

A total of 449 articles were identified, after removing duplicates, 339 titles and abstracts were screened, 18 were assessed in full, and 7 were included in the review. The highest shear bond strength was achieved with combined chemical and thermal treatment (24.49 ± 0.91 MPa), outperforming particle blasting (16.17 ± 1.30 MPa) and no treatment (13.73 ± 1.15 MPa). Blasting, however, showed better performance (5.71 ± 1.47 MPa) than chemical treatment alone (2.87 ± 0.44 MPa). Despite methodological variations, mechanical, chemical, and thermal treatments, applied individually or in combination, can enhance resin bonding. Bond strength was lower when combining printed and prefabricated components compared to fully printed parts.

Conclusions

Mechanical and chemical surface treatments effectively improve the bond strength between denture teeth and 3D-printed denture base resins. Enhancements in surface roughness, surface energy, and chemical interactions were associated with stronger adhesion.

表面处理对传统和3d打印义齿牙基结合的有效性：体外研究的系统回顾

研究问题3d打印修复体中基托与假牙之间的粘附受到物理化学差异的限制，这可能会影响结合强度并导致失败。发展策略，以提高这种粘附是至关重要的，以提高机械性能和临床成功的数字制造假体。研究的问题是：与传统的义齿基托树脂相比，不同的表面处理在提高预制和3d打印义齿与义齿基托树脂之间的结合强度方面的效果如何？材料和方法本综述遵循系统评价和荟萃分析首选报告项目（PRISMA），并在osf.io/mqncf上注册。文献检索通过5个数据库（PubMed, Embase, ScienceDirect, Web of Science, Scopus）和2个非同行评议文献来源（b谷歌Scholar和ProQuest）进行。应用RoBDEMAT工具评估纳入研究的偏倚风险。结果共纳入文献449篇，剔除重复后筛选出339篇题目及摘要，全文评价18篇，纳入综述7篇。化学热处理复合处理获得的剪切强度最高（24.49±0.91 MPa），优于颗粒爆破（16.17±1.30 MPa）和未处理（13.73±1.15 MPa）。爆破效果（5.71±1.47 MPa）优于单纯化学处理（2.87±0.44 MPa）。尽管方法不同，机械、化学和热处理，单独或联合应用，可以增强树脂粘合。与完全打印的部件相比，打印和预制部件结合时的粘合强度较低。结论机械表面处理和化学表面处理可有效提高义齿与3d打印义齿基托树脂的结合强度。表面粗糙度、表面能和化学相互作用的增强与更强的附着力有关。
