A technique to preserve spacer thickness during custom tray fabrication with autopolymerizing polymethylmethacrylate
Journal Title: International Journal of Dentistry Research - Year 2017, Vol 2, Issue 1
Abstract
A precisely fabricated custom tray is imperative for impression accuracy and proper application of desired pressure/relief on edentulous arches. Although custom impression tray fabrication has been greatly simplified with the use of light polymerizing resin material; autopolymerizing polymethylmethacrylate (PMMA) with baseplate wax as spacer, still remains a commonly used combination for edentulous custom tray fabrication. However, heat of polymerization released during exothermic setting reaction of autopolymerizing PMMA resin during tray fabrication frequently results in wax softening/ melting, causing dimensional distortion, tray contamination and discrepancy in predetermined thickness of the wax spacer that can jeopardise its very objective. This article describes a simple technique to prevent change in desired thickness of wax spacer during custom tray fabrication with autopolymerizing PMMA.
