In this study, the effects of surface pre-treatment and adhesive type on the shear bond strength between PEKK (polyetherketoneketone) and zirconia were analyzed by means of shear bond test and fracture aspect analysis.
RI group (sand blasted with 110 ¥ìm Rocatec + silane primer applied + Premier implant cement) showed the highest shear bond strength value (9.01 MPa), followed by AI (7.94 MPa), NI (5.62 MPa), RT (2.71 MPa), AT (2.25 MPa), and NT (non-treated + Hy-bond, 1.96 MPa) groups showed the lowest values. Analysis of shear bond strength according to the type of cement showed that the group using resin cement for implant was higher than the group bonded with polycarboxylate cement regardless of the surface treatment (p<0.05). As a result of analysis of shear bond strength according to the surface treatment, the silane primer applied to the surface of 110 ¥ìm particle size Rocatec showed the highest value (p<0.05). The fracture patterns of the specimens were analyzed by surface treatment and cement type. Polycarboxylate cement showed better bond strength with zirconia specimen and resin cement showed higher bond strength with PEKK specimen.
