Teeth supported overdenture
A tooth-supported overdenture rests on prepared natural teeth that help retain and stabilize the removable prosthesis.
The short answer
A tooth-supported overdenture rests on prepared natural teeth that help retain and stabilize the removable prosthesis. The teeth may be reshaped and covered with metal or ceramic copings, and the denture fits over them rather than replacing every root.
What is the direct answer?
What does this question mean?
An overdenture is removable, unlike a fixed bridge or crown. Its support can come from remaining teeth, implants, or both, so the design depends on the number, position, periodontal support, and restorability of the remaining teeth.
What can you do next?
The dentist examines the roots, bone, gums, bite, and denture space, then takes appropriate radiographs before planning. Treatment may include periodontal care, root canal treatment, tooth preparation, copings, impressions, a trial denture, and fitting adjustments.
When should you seek dental care?
Seek an assessment if a denture rocks, causes sore spots, traps food, or becomes difficult to remove or seat. Pain, bleeding, swelling, a fractured supporting tooth, or a loose coping should be checked promptly.
What should you ask the dentist?
Ask which teeth can support the design and how their gum and bone support will be maintained. Ask how the denture will be removed and cleaned, when relining may be needed, and whether an implant-supported alternative fits your anatomy.
Frequently asked questions
Is a tooth-supported overdenture fixed?
No. The patient removes it for cleaning, although the prepared teeth help it stay stable during use.
Can any remaining tooth support an overdenture?
No. It must have sufficient root, bone, gum, and restorative support after examination.
