Study Notes
Restorative Dentistry
- In restorative dentistry, ceramics are "drilled" by dentists when removing decay and then fired at high temperatures to become solid objects.
- Each material has its own requirements for cavity preparation design.
Direct Restorative Materials
- Direct restorative materials are putty-like materials that set to become hard and strong.
- Examples of direct restorative materials include:
- Amalgam, a metallic material formed by combining liquid mercury with powdered metals.
- Composites, esthetic materials that polymerize in the mouth.
- Glass ionomers and other cements, mortar-like materials that set by an acid-base chemical reaction in the mouth.
Indirect Restorative Materials
- Indirect restorative materials are plastics typically processed or cured at elevated temperatures and under high pressures.
- Examples of indirect restorative materials include:
- Porcelain crowns.
- Pink “gingival” portion of a denture.
Classification by Longevity of Use
- Permanent restorations are those that are not planned to be replaced in a particular time period.
- Although referred to as permanent, restorations do not last forever and will eventually need to be replaced.
Dental Implants
- Dental implants are screws or posts anchored into alveolar bone and protrude through the gingiva into the oral cavity.
- Implants are considered part of restorative dentistry but are segregated from other materials due to their specialized nature.
