|August 1, 1979
Summary
Copper plating on acrylic resin significantly enhances bond strength with polysulfide rubber compared to traditional adhesive coatings. This novel method improves material adhesion for dental applications.
Area of Science:
- Materials Science
- Biomaterials Engineering
- Surface Chemistry
Background:
- Acrylic resin trays are widely used in dentistry.
- Adhesion of polysulfide rubber to acrylic resins can be a limiting factor in tray performance.
- Current adhesive methods may exhibit interface failures.
Purpose of the Study:
- To develop a copper plating method for acrylic resin.
- To evaluate the bond strength between copper-plated acrylic resin and polysulfide rubber.
- To compare this novel method with conventional adhesive coatings.
Main Methods:
- Developed a copper plating technique for acrylic resin substrates.
- Measured bond strength of polysulfide rubber to both copper-plated and adhesive-coated acrylic resin.
- Analyzed failure modes (interface vs. cohesive-adhesive).
Main Results:
- Copper plating resulted in significantly greater bond strength compared to adhesive coating.
- Adhesive-coated specimens showed elastomer-adhesive interface failure.
- Copper-plated specimens exhibited cohesive-adhesive failure, indicating improved bonding.
Conclusions:
- Copper plating is a superior method for enhancing the adhesion of polysulfide rubber to acrylic resin.
- This technique improves the reliability of custom-built acrylic resin trays.
- The findings suggest a promising advancement in dental material bonding.
