Effects of Different Surface Treatments on the Tensile Bond Strength of Polymethyl Methacrylate Processed against Chemically Etched Ticonium 100
Abstract
Various techniques are presently available that improve the bonding of filled and unfilled resins to base metal alloys in prosthodontics. A few of these techniques have focused on surface treatments of alloys suitable for use in removable partial denture frameworks, and the resultant increase in bond strength between the alloy and acrylic resin. Polymethyl methacrylate, Lucitone 199, was processed against all surfaces following standard laboratory procedures. Thermocycling of samples was conducted to incorporate the effects of intraoral temperature and water sorption on bond strengths. Tensile bond strengths were measured with an Instron machine. SEM(scanning electron microscope)analysis of the fracture patterns revealed a correlation between bond strength and amount of residual resin on the etched surfaces.
