Glossary Entry: Overdenture

Overview

Definition: An overdenture is a type of removable dental prosthesis that covers and is supported by one or more remaining natural teeth, dental implants, or both. It serves as a replacement for missing teeth and offers improved stability and retention compared to conventional complete dentures.

Detailed Description

Types and Variations

Variations: Overdentures can be classified based on the number and location of supporting teeth or implants. They can either be tooth-supported overdentures or implant-supported overdentures, each offering unique advantages in terms of stability and function.

Indications

Common Uses: Overdentures are commonly used in patients who have few remaining teeth or inadequate bone support for conventional dentures. They are often recommended to improve chewing efficiency and enhance facial aesthetics.

Insertion and Placement

Procedure: The placement of an overdenture involves careful assessment of the remaining teeth or implants to ensure proper fit and stability. The dentist may use attachments or bars to secure the overdenture to the supporting structures securely.

Clinical Considerations

Potential Complications

Risks: Complications associated with overdentures may include inflammation of the supporting tissues, loosening of attachments, or excessive wear of the prosthetic components. Regular follow-ups with the dentist are essential to monitor and address any issues promptly.

Care and Maintenance

Maintenance Requirements: Proper oral hygiene practices, including regular cleaning of the overdenture and supporting structures, are crucial to prevent infections and maintain oral health. Denture adhesives or cleaning solutions may be recommended for daily care.

Additional Information

Related Devices

Associated Terms: Bar-supported overdentures, attachment-retained overdentures, implant-supported overdenture abutments.

Innovations and Advancements

Recent Developments: Advances in implant technology have improved the success rate and longevity of implant-supported overdentures. The introduction of CAD/CAM technology has also enhanced the precision and fit of overdenture prosthetics.

Regulatory and Safety Notes

Regulations: Dentists must follow established guidelines and regulations for the fabrication and placement of overdentures to ensure patient safety and quality of care.
