SURFACE MODIFICATION OF DENTAL DEVICES - Surface Analysis of Plasma-based Fluorine and Silver Ion Implanted & Deposited Acrylic Resin

Abstract

The aim of this study was to modify acrylic resin (PMMA) with fluorine (F) and silver (Ag) dual ions by a hybrid process of plasma-based ion implantation & deposition (PBII-D), and to enable the surface of the devices inhibition of bacterial adhesion. The surface characteristics, hydrophobic property and brushing abrasion resistance were evaluated by XPS analysis, contact angle measurement and brushing abrasion test. F and Ag were implanted-deposited and have formed carbon-fluoride and Ag-deposited layer on the surface of the PMMA plate. The contact angle of F+Ag implanted-deposited PMMA was increased compared with non-treated control and F only deposited PMMA. After 60,000 brushing strokes, the contact angle of modified PMMA remained to be higher than that of the control PMMA. This study indicated that F+Ag implantation-deposition has improved the hydrophobic property of acrylic resin and was sustained even after routine tooth brushing.
