This study researched the effects of different surface conditioning techniques on the bond strength of polyetherketoneketone (PEKK) with lithium disilicate glass-ceramic material. Total of 105 test specimens were prepared from PEKK discs and randomly distributed into 5 experimental groups (n = 21) to which different surface conditioning techniques were applied. [Group A: sandblasting + SR Connect adhesive agent (SRC), Group B: dichloromethane (DCM) + SRC, Group C: methyl methacrylate (MMA) and DCM mixture + SRC, Group D: sandblasting + DCM + SRC, Group E (control): sandblasting + Pekk Bond adhesive agent (PB).] Surface roughness values of PEKK test specimens were measured. They were bonded to lithium disilicate glass-ceramic test specimens with resin cement. Half of them were subjected to thermomechanical aging. Shear bond strength measurements were made. Among the A, B, C, D, and E groups, a statistically significant difference was observed in terms of the surface roughness values (p < 0.001). Statistically significant differences were obtained among the thermomechanical aging groups (p < 0.001) and among the non-thermomechanical aging groups (p = 0.012) in terms of shear bond strength. Group D and Group E demonstrated clinically acceptable bond strength values when bonding PEKK material with lithium disilicate glass-ceramic material. (C) 2022 The Electrochemical Society ("ECS").
