本研究报告了一种新开发的实验性光固化玻璃离子水门汀的体外磨损评价结果，该水门汀由合成的六臂星星形聚丙烯酸和Fuji II LC玻璃填料组成。树脂复合材料P-60以及玻璃离子水门汀Fuji II和Fuji II LC用于比较。在测试之前，将所有样品在37°C的蒸馏水中调理1天。实验骨水泥的耐磨性在统计学上与P-60相同，但实验骨水泥的耐磨性比Fuji II和Fuji II LC高14倍。此外，实验骨水泥的耐磨性比Fuji II和Fuji II LC高1.4倍，但比P-60低6倍。令人印象深刻的是，老化1个月后，实验骨水泥能够在耐磨性方面与P-60竞争，显示出的磨损深度仅为P-60的1.3倍。 这种新型骨水泥似乎是一种具有临床吸引力的牙科修复体，可用于I类和II类牙列缺损等高磨损部位。
This study reports the results of an evaluation on thein vitrowear of a newly developed experimental light‐cured glass‐ionomer cement composed of the synthesized six‐arm star‐shape poly(acrylic acid) and Fuji II LC glass fillers. The resin composite P‐60, as well as glass‐ionomer cements Fuji II and Fuji II LC, were used for comparison. All specimens were conditioned in distilled water at 37°C for 1 d prior to testing. The experimental cement exhibited statistically the same wear‐resistance to abrasion as P‐60, but the wear‐resistance was 14 times higher for the experimental cement than for Fuji II and Fuji II LC. Furthermore, the experimental cement showed a degree of wear‐resistance to attrition that was 1.4 times higher than both Fuji II and Fuji II LC but six times lower than that of P‐60. Impressively, after 1 month of aging the experimental cement was able to compete with P‐60 in wear‐resistance to attrition, showing a degree of wear depth that was only 1.3 times more than that of P‐60. It appears that this novel cement is a clinically attractive dental restorative that can be potentially used for high‐wear sites such as class I and class II restorations.
