摘要:

氢氟酸是常见的玻璃陶瓷修复体粘接前的表面处理剂,但使用氢氟酸存在较高的安全风险,因此寻找氢氟酸替代物一直是研究热点。四丁基双氟氢氟化铵是一种氟化物,化学活性低于氢氟酸,所以安全性更高,对玻璃陶瓷表面形态改变也更小、更表浅。目前,大多数实验室研究和临床病例报告表明,四丁基双氟氢氟化铵表面处理后的玻璃陶瓷的机械强度、粘接强度能够满足临床需求,并且四丁基双氟氢氟化铵在部分国家已经作为氢氟酸替代物用于临床。将来,还可根据研究结果进一步改进含四丁基双氟氢氟化铵的瓷表面处理剂的性能,或者研究出更多的氢氟酸替代物。本文从对玻璃陶瓷的表面形态、机械强度、粘接强度的影响方面,对四丁基双氟氢氟化铵作为氢氟酸替代物的研究进展进行综述。

Abstract:

Hydrofluoric acid is a common surface treatment agent for glass ceramic restorations before bonding. However, the use of hydrofluoric acid has a high safety risk, so the search for hydrofluoric acid substitutes has been a research hotspot. Tetrabutylammonium dihydrogen trifluoride is a kind of fluoride, whose chemical activity is lower than that of hydrofluoric acid, so it’s safer, and the surface morphology changes on glass ceramics caused by it are smaller and more superficial. At present, the vast majority of laboratory studies and clinical case reports indicate that the mechanical strength and bonding strength of glass ceramics treated with tetrabutylammonium dihydrogen trifluoride can meet the clinical requirements. In the future, according to the research results, the performance of porcelain surface treatment agents containing tetrabutylammonium dihydrogen trifluoride can be further improved, and more hydrofluoric acid substitutes may be developed. In this review, the research progress of tetrabutylammonium dihydrogen trifluoride as a substitute for hydrofluoric acid is reviewed in terms of the influence of the surface morphology, mechanical strength, and bonding strength of glass ceramics.

Key words: glass ceramics; surface treatment; hydrofluoric acid; tetrabutylammonium dihydrogen trifluoride; self-etching surface treatment agent; surface morphology; mechanical strength; bonding strength
