INTRODUCTION AND AIMS: Traditional dental composite resins faced persistent challenges regarding biofilm accumulation and hydrolytic degradation. This study aimed to develop a novel resin monomer fluorinated polyurethane dimethacrylate (FPUDMA) and surface-modified polyether ether ketone (PEEK) fillers to enhance the comprehensive performance of composite resins.
METHODS: FPUDMA was synthesized via solution polymerization, while PEEK was hydroxylated and grafted with KH570 to introduce C=C bonds. Experimental composite resins were formulated with varying concentrations of PEEK-C=C at 0%, 2.5%, 5%, and 7.5% by weight. Key properties evaluated included degree of conversion, depth of curing, water sorption/solubility, mechanical properties (before/after aging), polishability, initial bacterial adhesion, and cytocompatibility.
RESULTS: FPUDMA and PEEK-C=C were confirmed by FTIR, NMR, and XPS. Increasing PEEK-C=C content reduced the degree of conversion and curing depth, but all values met ISO standards. There was no significant difference in water absorption/solubility among the groups. As the increase of PEEK-C=C content, the flexural strength, elastic modulus, and surface hardness significantly increased, but decreased at 7.5% group, whether before or after aging (P<0.05). All groups exhibited favorable polishing performance and cytocompatibility (cell viability >90%). The FPUDMA monomer could still maintain anti-bacterial adhesion properties when incorporated into the resin.
CONCLUSION: The novel composite resin with FPUDMA and 5 wt% PEEK-C=C fillers demonstrated optimized mechanical properties, acceptable polymerization characteristics, resistance to bacterial adhesion, and favorable biocompatibility.
CLINICAL RELEVANCE: These improvements are expected to mitigate degradation at the tooth-restoration interface, thereby reducing the risk of secondary caries and restoration fracture. Consequently, the novel resin represents a clinically viable option for durable dental restorations.
