  Purpose

The aim of this study is to evaluate the antibacterial activity of crosslinked quaternary ammonium polyethylenimine (PEI) nanoparticles incorporated at 1-2% w/w in a commercial soft liner material when compared to the commercial soft liner material.

The investigators' results in vitro showed a significant delay in bacterial growth.

Therefore, the investigators assume to have the same delay in vivo- on patients.
