摘要
目的 本研究评估了钛基台阳极氧化对二硅酸锂（LDS）全瓷牙冠颜色参数和色差的影响。 材料和方法 在这项研究中，19 个直基台被分为两组：阳极氧化组（n = 9）和非阳极氧化对照组（n = 9），还有一个混合氧化锆基台作为参照。阳极氧化是通过使用七节串联的 9 V 平板电池，在 250 mL 蒸馏水中加入 1 g 磷酸三钠的电解质溶液，施加 63 V 的能量，持续 5 s，使其呈现金黄色。然后对基台进行扫描，制作厚度为 2 毫米的全轮廓整体式 IPS e.max 中切牙牙冠并上釉。使用分光辐射计测量反射率，并使用 CS-10W 软件计算色坐标（L*、a*、b*、h* 和 C*）。使用 CIEDE2000（ΔE00）色差公式量化两组牙冠的色差，并与标准样本进行 t 检验（α = 0.05）分析。 结果 阳极氧化基台的 L*、a*、b* 和 c* 参数明显高于非阳极氧化基台，而阳极氧化基台的 h* 参数明显低于非阳极氧化基台（均为 p <0.001）。两组的 ΔE00 存在明显差异（p = 0.043）。 结论 与未经阳极氧化处理的基台相比，钛基台阳极氧化处理可改善 LDS 全瓷冠的颜色参数，并显著降低其 ΔE。
In Vitro Effect of Anodization of Titanium Abutments on Color Parameters and Color Difference of Lithium Disilicate All-Ceramic Crowns
Objective
This study assessed the effect of the anodization of titanium abutments on the color parameters and color difference of lithium disilicate (LDS) all-ceramic crowns.
Materials and Methods
In this study, 19 straight abutments were divided into two groups: anodized (n = 9) and non-anodized control (n = 9), with one hybrid zirconia abutment as a reference. Anodization was achieved by applying 63 V energy using seven 9 V flat batteries in series, with an electrolyte solution comprising 1 g trisodium phosphate in 250 mL distilled water for 5 s, resulting in a gold-yellow color. Abutments were then scanned, and full-contour monolithic IPS e.max maxillary central incisor crowns were fabricated with 2 mm thickness and glazed. Reflectance was measured using a spectroradiometer, and color coordinates (L*, a*, b*, h*, and C*) were calculated using CS-10W software. Color differences of the crowns in both groups were quantified using the CIEDE2000 (ΔE00) color difference formula and analyzed by t-test (α = 0.05) compared to the standard sample.
Results
The L*, a*, b*, and c* parameters in anodized abutments were significantly higher than those in non-anodized abutments, while the h* parameter in anodized abutments was significantly lower than that in non-anodized abutments (p < 0.001 for all). There was a significant difference in ΔE00 of the two groups (p = 0.043).
Conclusion
Anodization of titanium abutments improved the color parameters of LDS all-ceramic crowns and significantly decreased their ΔE compared with non-anodized abutments.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
