摘要
本研究旨在阐明 3D 打印牙科材料与 CAD/CAM 块的颜色和半透明性。根据着色剂类型和储存时间，对三种不同的含陶瓷、树脂基 CAD/CAM 块和一种 3D 打印树脂进行了热循环后评估，并评估了它们的褪色程度。采用重复测量方差分析和 Tukey 后验法对数据进行了分析。红葡萄酒中所有物质的 ∆E00 值都高于临床公认的阈值。在 1 周和 1 个月时，3D 材料的褪色程度在统计学上明显高于其他 3 种材料（p
Comparison of discoloration of ceramic containing 3D printable material and CAD/CAM blocks.
This study aimed to clarify aspects of the color and translucency of 3D printed dental material with CAD/CAM blocks. Three different ceramic-containing, resin-based CAD/CAM blocks and a 3D printable resin were evaluated after thermocycled and assessed for their degree of discoloration based on colorant types and storage times. Data were analyzed using repeated-measures analysis of variance followed by Tukey's post-hoc test. All materials in red wine had ∆E00 values higher than the clinically accepted threshold value. At 1 week and 1 month, the 3D material was statistically significantly more discolored than the other 3 materials (p<0.05). None of the materials exceeded the acceptable threshold value at any time point. The color changes increased over time in resin-based CAD/CAM blocks and 3D printable dental materials. After 1 week and 1 month, there was a statistically significant difference in the color change between the 3D printed material and the CAD/CAM blocks.
期刊介绍：
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
