Study Notes
Self-Cured Acrylic Resin for Bleaching Trays
- Self-cured acrylic resin is typically supplied in a powder-liquid form for easy mixing and application in the fabrication of bleaching trays.
- This type of resin is preferred for bleaching trays due to its ability to harden without the need for additional curing lights, simplifying the production process.
- A characteristic feature of self-cured acrylic resin is its exothermic reaction during the hardening process, which generates heat as it sets.
- The mixing of self-cured acrylic resin occurs during the initial phase of tray fabrication, where the powder and liquid components are combined to create a workable material.
- An important consideration when using self-cured acrylic resin is to ensure accurate measurement of the powder and liquid to achieve the correct consistency and optimal properties for the bleaching tray.
