Abstract

Bioactive resin cements are gaining popularity for their clinical benefits, but concerns remain regarding their color stability. This study evaluated the color change (ΔE₀₀) and whiteness change (ΔWI_D) in bioactive resin cements and how their potential discoloration affects the shade of bonded CAD/CAM glass-ceramics at different ceramic thicknesses. VITA Mark II blocks were prepared in three thicknesses (0.5, 0.8, and 1.0 mm) and divided by resin cement: Panavia SA Universal (Pn), Predicta Bioactive Cement (Pr), and ACTIVA BioACTIVE Cement (Ac) (n = 10). Additionally, 10 specimens (10 × 2 mm) of each cement alone were prepared. Color was measured before and after 24 days of coffee immersion. Cement type significantly affected ΔE₀₀ (p < 0.001). Pn had the highest color stability, followed by Pr and Ac, with significant differences between each. ΔWI_D also varied by cement (p = 0.004), with Pn and Pr differing significantly from Ac. Ceramic thickness alone had no significant effect on ΔE₀₀ or ΔWI_D, but its interaction with cement type was significant (p < 0.001). While ceramic thickness does not directly affect the final shade, its combination with resin cement does. Choosing the right resin cement is key for long-term esthetic outcomes.

生物活性树脂水泥颜色稳定性和修复厚度是玻璃陶瓷CAD/CAM材料最终色度的决定因素。

生物活性树脂胶合剂因其临床益处而越来越受欢迎，但其颜色稳定性仍然令人担忧。本研究评估了生物活性树脂水泥的颜色变化（ΔE00）和白度变化（ΔWID），以及它们的潜在变色如何影响不同陶瓷厚度的结合CAD/CAM微晶玻璃的色度。制备三种厚度（0.5、0.8和1.0 mm）的VITA Mark II块，并用树脂水泥分为：Panavia SA Universal （Pn）、Predicta Bioactive cement （Pr）和ACTIVA Bioactive cement (Ac) （n = 10）。此外，每种水泥单独制备10个试件（10 × 2mm）。在咖啡浸泡24天之前和之后测量颜色。水泥类型显著影响ΔE00 （p < 0.001）。Pn的颜色稳定性最高，Pr和Ac次之，两者之间差异显著。ΔWID也因水泥而异（p = 0.004）， Pn和Pr与Ac差异显著。陶瓷厚度本身对ΔE00或ΔWID没有显著影响，但其与水泥类型的相互作用显著（p < 0.001）。虽然陶瓷的厚度不直接影响最终的色调，但它与树脂水泥的结合会影响最终的色调。选择正确的树脂水泥是长期美观效果的关键。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
