Synthesis and characterization of a new 2-iminothiolate-modified dimethacrylate monomer with potential dental applications
Puntos clave
This research aims to develop a new dimethacrylate monomer to improve dental resin composites.
Synthesize a 2-iminothiolate-modified dimethacrylate monomer
Characterize the chemical properties of the new monomer
Evaluate the effects on polymerization shrinkage and microleakage
The new monomer reduces polymerization shrinkage compared to conventional materials
Decreased microleakage was observed, indicating improved sealing properties
Enhanced free volume and increased steric hindrance contribute to the performance improvements
Resumen
Chemical modification of Bis-GMA with bulky side-chains increases free volume and steric hindrance, effectively reducing polymerization shrinkage and microleakage in dental resin composites.
