Glossary Entry: Dental Bridge

Overview

Definition: A dental bridge is a fixed dental restoration used to replace one or more missing teeth by bridging the gap between adjacent teeth. It consists of artificial teeth (pontics) held in place by dental crowns on the natural teeth on either side of the gap.

Detailed Description

Types and Variations

Variations: Dental bridges can be made from various materials such as porcelain, metal, or a combination of both. They can also be classified based on their design, including traditional bridges, cantilever bridges, and Maryland bridges.

Indications

Common Uses: Dental bridges are commonly used to restore aesthetics, improve chewing and speech function, and prevent the drifting of surrounding teeth due to tooth loss.

Insertion and Placement

Procedure: The dentist prepares the abutment teeth by removing a portion of their enamel to accommodate the crowns. Impressions are taken to create a custom-fit bridge, which is then cemented in place by the dentist.

Clinical Considerations

Potential Complications

Risks: Potential risks associated with dental bridges include decay of the abutment teeth, gum disease, and bridge failure due to poor oral hygiene or structural issues.

Care and Maintenance

Maintenance Requirements: Proper oral hygiene practices, including regular brushing, flossing, and professional cleanings, are essential for maintaining the longevity of a dental bridge. Avoiding hard or sticky foods can also help prevent damage to the bridge.

Additional Information

Related Devices

Associated Terms: Dental crowns, dental implants, and dentures are common devices used in conjunction with dental bridges to restore missing teeth.

Innovations and Advancements

Recent Developments: Modern dental bridges now incorporate advanced materials like zirconia for improved aesthetics and durability. Digital technology has also enabled precise CAD/CAM fabrication of bridges for optimal fit and function.

Regulatory and Safety Notes

Regulations: Dental bridges must meet specific quality and safety standards set by regulatory bodies to ensure patient safety and comfort during treatment.
