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.
