A comparative in vitro study on monomer release from flash-free or conventional bonding systems

This is the first study that evaluates the residual monomer release from adhesive-precoated flash-free brackets. The novel bracket system has a different mesh structure at the bracket base compared to traditional systems with different chemical components which might alter the amount of residual monomer release. To investigate the harmful effects of adhesives used in orthodontic applications is very important for the health of the patient and the orthodontist.
