Study Notes
Denture Bases
- Polymethyl Methacrylate (PMMA) is commonly used for making denture bases.
Heat Cure PMMA Composition
- Benzoyl Peroxide is a component in heat cure PMMA composition that initiates polymerization.
- The powder component of heat cure PMMA is a mixture of Poly(Methyl Methacrylate) and Benzoyl Peroxide.
Function of Benzoyl Peroxide
- Benzoyl Peroxide acts as a catalyst to initiate the polymerization reaction during the heat cure process.
Uses of PMMA in Dentistry
- PMMA is used in dentistry to fabricate denture bases, temporary crowns, and orthodontic appliances.
Heat Cure PMMA Polymerization
- The active part of heat cure PMMA that polymerizes during the heat cure process is the Methyl Methacrylate monomer.
Test your knowledge on dental acrylics and their uses in dentistry. Learn about PMMA (polymeric heat cured acrylic resin) and its applications in denture bases, artificial teeth, customised trays, orthodontic appliances, soft liners, and denture repairs.
