Study Notes
Composition of Acrylic Resin
- Primarily composed of polymethyl methacrylate (PMMA) monomers.
- May include additives such as pigments, fillers, cross-linking agents, and plasticizers.
Other Names for Dental Resin
- Commonly referred to as acrylic resin in dental applications.
Classifications of Resins Based on Thermal Behavior
- Thermoplastic resins: Soften upon heating and can be reshaped.
- Thermosetting resins: Harden irreversibly when cured and cannot be remolded.
Function of the Cross-Linking Agent
- Enhances the mechanical properties and stability of acrylic resin.
- Creates a network structure, improving resistance to changes in temperature and chemicals.
Function of the Inhibitor
- Prevents premature polymerization of acrylic resin, prolonging shelf life.
- Stabilizes the resin during storage and handling before use.
Function of the Initiator
- Initiates the polymerization process, allowing the monomers to link together and form the solid resin.
- Essential for achieving the desired consistency and strength of the final product.
Role of the Plasticizer
- Improves the flexibility and workability of acrylic resin.
- Reduces brittleness, making the final product more durable.
Classification of Acrylic Resin Based on Thermal Behavior
- Classified as thermoplastic resin due to its ability to soften when heated and re-harden upon cooling.
