This study aimed to evaluate the shear bond strength of two flowable composite resins to resin-matrix ceramic CAD-CAM materials.Fifty-four plates obtained from Lava Ultimate (LU), Cerasmart (CS), and Vita Enamic (VE) CAD-CAM blocks were assigned to nine groups: N0: Nova Compo SF (NCSF), N1: Silane/Single Bond Universal (SBU)/NCSF, N2: SBU/NCSF, N3: Silane/G-Premio Bond (GPB)/NCSF, N4: GPB/NCSF, G1: Silane/SBU/G-aenial Universal Injectable Composite (GUIC), G2: SBU/GUIC, G3: Silane/GPB/GUIC, G4: GPB/GUIC. After the repair procedures, shear bond strength values were analyzed. Silane pre-application decreased bond strength in most LU and CS groups but increased it in VE. NCSF performed better than GUIC in all CAD-CAM's with similar adhesive protocols. SBU in combination with NSCF had the highest bond strength among all repair procedures in LU and CS. Silane-containing universal adhesives in combination with self-adhesive resin composites should be used to repair resin-matrix ceramic materials.
本研究旨在评估两种流动复合树脂与树脂基质陶瓷 CAD-CAM 材料的粘结强度。从 Lava Ultimate (LU)、Cerasmart (CS)和 Vita Enamic (VE) CAD-CAM 块获得的 54 个板被分为九组：N0：Nova Compo SF (NCSF)、N1：Silane/Single Bond Universal (SBU)/NCSF、N2：SBU/NCSF、N3：Silane/G-Premio Bond (GPB)/NCSF、N4：GPB/NCSF、G1：Silane/SBU/G-aenial Universal Injectable Composite (GUIC)、G2：SBU/GUIC、G3：Silane/GPB/GUIC、G4：GPB/GUIC。修复程序后，分析了剪切粘结强度值。硅烷预处理降低了大多数 LU 和 CS 组的粘结强度，但增加了 VE 的粘结强度。在所有具有相似粘合协议的 CAD-CAM 中，NCSF 比 GUIC 表现更好。在 LU 和 CS 中，所有修复程序中 SBU 与 NCSF 结合的粘结强度最高。应使用含硅烷的通用粘合剂与自粘树脂复合材料结合来修复树脂基质陶瓷材料。
