Study Notes
Dental Biomaterials
- Polymorphism in dental biomaterials refers to the ability of a material to exist in multiple crystalline forms.
Bonding in Dental Materials
- Theoretical strength of a bond can be higher than its actual strength due to the presence of defects, which characterizes a brittle bond.
Denture Bases
- A denture base primarily consists of a resin, such as acrylic or polyamide.
Crystal Structures
- The fraction of space occupied by atoms in a unit cell represents the packing density or atomic packing factor (APF).
Dental Applications
- The primary component of a denture base in dental applications is a resin, such as acrylic or polyamide.
- Artificial teeth in dental applications are commonly made of porcelain.
