What does “Overdenture” mean?
An overdenture is a removable denture that covers remaining teeth, roots, or implants to gain support or retention.
Structure of an implant-supported overdenture
Attachments on implants engage components inside the denture to help resist dislodgement. Depending on design, the gums also share chewing forces. Designs include connecting bars and individual attachments.
How it differs from a fixed full-arch prosthesis
The patient can remove an overdenture for cleaning. Its care differs from a fixed prosthesis that the patient does not remove. The number and positions of implants depend on the upper or lower jaw, remaining bone, space, and design; one number does not apply to all cases.
Care for retention components and gums together
Clean the denture interior, attachments, and gums separately. Retention components can wear and lose their hold, and changes in base fit may require adjustment. Reduced attachment retention must be distinguished from movement of the implant body.
Frequently Asked Questions
Is an overdenture always an implant denture?
In its broader meaning, it also includes dentures covering remaining teeth or roots. An implant overdenture gains retention or support from implants.
Does a loose denture mean implant failure?
It may reflect worn retention components or changed denture fit. Assess body stability, attachments, and gum support separately.
