Key Points

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

Implication

Chemical modification reduces polymerization shrinkage in dental composites, suggesting improved quality and durability.

Abstract

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.
