Silicate ceramic bonding is carried out by acid-etching with hydrofluoric acid (HF) followed by an application of silane. By replacing HF with ammonium polyfluoride, contained in the same flask as the silane, the number of steps in this clinical procedure, can be reduced, while maintaining bond strength values, and reducing toxicity. A shear bond test was performed to compare the conventional and the simplified surface treatment techniques.
Twenty ceramic samples were fabricated from IPS emax CAD® ceramic (Ivoclar Vivadent) and divided into two groups (G1 and G2) (n=10). The conventional technique was applied to G1 samples, and the simplified technique to G2 samples. A resin cement cylinder was bonded to each sample. Afterwards, samples underwent shear bond strength testing in a universal test machine.
G1 obtained 26.53±6.33 MPa and G2 23.52±8.41 MPa, without statistically significant differences between the two groups.
Monobond Etch&Prime appears to obtain equivalent results in terms of bond strength while simplifying the technique. Further investigation is required to corroborate these preliminary findings. Shear bond strength, surface treatment, bonding to ceramic, hydrofluoric acid, ammonium polyfluoride.
硅酸盐陶瓷粘结通过用氢氟酸（HF）进行酸蚀，然后施加硅烷来进行。通过用与硅烷装在同一烧瓶中的聚氟化铵替代HF，可以减少该临床操作的步骤数量，同时保持粘结强度值并降低毒性。进行了剪切粘结试验以比较传统和简化的表面处理技术。
用IPS emax CAD®陶瓷（义获嘉伟瓦登特公司）制作20个陶瓷样品，并分为两组（G1和G2）（n = 10）。对G1组样品采用传统技术，对G2组样品采用简化技术。将树脂水泥圆柱体粘结到每个样品上。之后，在万能试验机中对样品进行剪切粘结强度测试。
G1组获得26.53±6.33MPa，G2组获得23.52±8.41MPa，两组之间无统计学显著差异。
在简化技术的同时，Monobond蚀刻与底涂剂在粘结强度方面似乎能获得等效结果。需要进一步研究来证实这些初步发现。剪切粘结强度、表面处理、与陶瓷的粘结、氢氟酸、聚氟化铵。
