STATEMENT OF PROBLEM: The chemically inert and low surface energy characteristics of polyetheretherketone (PEEK) have been reported to hinder reliable adhesion to resin-matrix cements, and the effectiveness and clinical feasibility of different surface pretreatment protocols to improve bond strength remain unclear.
PURPOSE: The purpose of this systematic review and meta-analysis was to compare the efficacy of different surface treatments on the bond strength of PEEK to resin cements.
MATERIAL AND METHODS: A comprehensive search of 4 electronic databases, PubMed, Scopus, Embase, and Web of Science, was performed to identify relevant studies published through October 2025. In vitro evaluations of bond strength between PEEK materials and resin cements after different surface treatments were included.
RESULTS: A total of 22 studies were included in the descriptive and meta-analyses. Compared with no surface treatment, both 98% sulfuric acid etching and APA with 50-µm aluminum oxide significantly improved the outcome, with a markedly greater effect for sulfuric acid etching (SMD=3.88; 95% CI:2.00-5.76) than APA (SMD=1.81;95% CI:1.19-2.43). This superiority was further confirmed by direct comparison between the 2 protocols (SMD=-1.10; 95% CI: -2.61 to -0.41). Additionally, thermocycling significantly reduced the bond strength of sulfuric acid etching compared with nonaged specimens (SMD=0.73;95% CI:0.25-1.71). MMA-based primers and adhesives showed the highest bond strength.
CONCLUSIONS: Both sulfuric acid etching and airborne-particle abrasion significantly improved the bond strength compared with no surface treatment. Sulfuric acid etching showed greater degradation after thermocycling, while airborne-particle abrasion offered more stable bond strength than aging. The use of primers and adhesive systems containing MMA significantly improved the bond strength of PEEK.
