The specimens were all bonded by using a MMA-based adhesive (Single Bond Universal). A luting agent (RelyX U200) was used to bond the composite resin (Universal Filtek Z350 X T) to the pretreated PEEK surfaces. An Instron universal machine was used to calculate the SBS between the PEEK and the composite resin following ISO 10477. Failure modes (cohesive, adhesive, and mixed) and interface morphology were analyzed by stereomicroscopy.
