Glossary Entry: Dental Crown

Overview

Definition: A dental crown is a cap-like restoration used to cover a damaged or decayed tooth to restore its shape, size, strength, and appearance. It is custom-made to fit over the tooth and is cemented into place.

Detailed Description

Types and Variations

Variations: Dental crowns can be made from various materials such as metal, porcelain-fused-to-metal, all-ceramic, and zirconia. Each type has specific aesthetic and functional properties.

Indications

Common Uses: Dental crowns are commonly used to protect weakened teeth, restore broken or severely decayed teeth, cover dental implants, improve the appearance of misshapen or discolored teeth, and support dental bridges.

Insertion and Placement

Procedure: The tooth is prepared by removing a portion of the outer layer to accommodate the crown. Impressions are taken to create a custom-made crown that fits perfectly over the prepared tooth. The crown is then cemented in place.

Clinical Considerations

Potential Complications

Risks: Potential risks associated with dental crowns include sensitivity, crown fracture, allergic reactions to materials, and complications with the underlying tooth structure.

Care and Maintenance

Maintenance Requirements: Proper oral hygiene practices, including regular brushing and flossing, as well as routine dental check-ups, are essential to maintain the longevity and integrity of the dental crown.

Additional Information

Related Devices

Associated Terms: Dental crowns may be used in conjunction with dental bridges, dental implants, or veneers to address various dental concerns.

Innovations and Advancements

Recent Developments: Advancements in dental technology have led to the development of stronger and more aesthetically pleasing materials for dental crowns, enhancing their durability and natural appearance.

Regulatory and Safety Notes

Regulations: Dental crowns must meet regulatory standards for materials and durability to ensure patient safety and effectiveness.
