Polyetheretherketone (PEEK) is a thermoplastic material widely used in engineering applications due to its good biomechanical properties and high temperature stability. Compared traditional metal ceramic dental materials, PEEK implants exhibit less stress shielding, thus better matching the mechanical of bone. As promising medical material, can be as implant abutments, removable fixed prostheses, maxillofacial prostheses. It blended with materials such fibers ceramics improve strength for clinical applications. conventional pressed CAD/CAM milling fabrication, 3D-printed exhibits excellent flexural tensile parameters printing speed affect properties. However, bioinert nature make adhesive bonding difficult. The bond improved by roughening or introducing functional groups on surface sandblasting, acid etching, plasma treatment, laser systems.

This study aimed clarify the type of cement most suitable for bonding PEEK: methyl methacrylate (MMA)-based or composite-based For this purpose, two MMA-based cements (Super-Bond EX and MULTIBOND II) five (Block HC Cem, RelyX Universal Resin Cement, G-CEM LinkForce, Panavia V5, Multilink Automix) were used combination appropriate adhesive primers. A PEEK block (SHOFU PEEK) was initially cut, polished, sandblasted alumina. The then bonded primer according manufacturer’s instructions. resulting specimens immersed water at 37 °C 24 h, followed thermocycling. Subsequently, tensile strengths (TBSs) measured; TBSs after thermocycling found be zero (G-CEM Automix), 0.03 ± 0.04 (RelyX Cement), 1.6 2.7 Cem), whereas those Super-Bond 11.9 2.6 4.8 2.3 MPa, respectively. results demonstrated that exhibited stronger than cements.
