The surface treatment of glass-ceramic-based materials, namely, lithium disilicate glass (IPS e.max CAD), feldspar porcelain (VITABLOCS Mark II), and a polymer-infiltrated ceramic network (VITA ENAMIC), using aqueous fluoride solutions and their influence on luting agent bonding were investigated. Six experimental aqueous fluoride solutions were applied to these materials, and their effects were assessed by surface topological analysis. The obtained results were compared using non-parametric statistical analyses. Ammonium hydrogen fluoride (AHF) etchant demonstrated the greatest etching effect. Subsequent experiments focused on evaluating different concentrations of the AHF etchant for the bonding pretreatment of glass-ceramic-based materials with a luting agent (PANAVIA V5). AHF, particularly at concentrations above 5 wt%, effectively roughened the surfaces of the materials and improved the bonding performance. Notably, AHF at a concentration of 30 wt% exhibited a more pronounced effect on both etching and bonding capabilities compared to hydrofluoric acid.
采用含氟水溶液对玻璃陶瓷材料（即二硅酸锂玻璃[IPS e.max CAD]、长石瓷[VITABLOCS Mark II]和聚合物渗透陶瓷网络[VITA ENAMIC]）进行表面处理，并研究其对水门汀粘结的影响。将六种实验性含氟水溶液应用于这些材料，并通过表面拓扑分析评估其效果。使用非参数统计分析比较获得的结果。结果表明，氟化氢铵（AHF）蚀刻剂的蚀刻效果最佳。随后的实验集中于评估不同浓度的 AHF 蚀刻剂对玻璃陶瓷基材料与水门汀（PANAVIA V5）粘结预处理的影响。AHF，特别是浓度高于 5wt%时，可有效粗化材料表面，提高粘结性能。值得注意的是，与氢氟酸相比，浓度为 30wt%的 AHF 在蚀刻和粘结能力方面的效果更为显著。
