Many/all teeth missing: fixed vs removable

A fixed implant restoration stays attached, while dentures are removable replacements for a full set of missing teeth.

[1][2]

The short answer

For a full set of missing teeth, implant-supported fixed teeth remain in place, while complete dentures are removable.

Which option stays fixed?

How the two full-mouth replacement routes are supported
QuestionImplant-supported fixed teethComplete dentures
How they are heldImplants retain or support the prosthesis in the jaw.They are removable false teeth.[1][2]
Where they are usedThey can restore a fully toothless upper or lower jaw.They replace missing teeth and can be taken out.[1][2]

[1][2]

When does a fixed implant restoration fit the decision?

A fixed implant-supported complete prosthesis is one route used after all teeth are missing; implant overdentures are another implant-supported route.

[1][2]

When is a removable denture the alternative?

A denture is the removable option. It can replace missing teeth, while bridges and implants are fixed alternatives for replacing teeth.

[2]

What changes the treatment route?

The practical difference is the form of support: a fixed implant restoration is supported by implants, while a complete denture is removable.

[1][2]

What needs watching over time?

A denture that clicks, slips, causes pain, becomes worn, or no longer fits properly needs assessment. Red or bleeding gums and bad breath also need attention.

Clicking or slippingThe denture may no longer fit properly.[1][2]
Pain or damageThe denture may be causing discomfort or may be worn or broken.[1][2]

[1][2]

What can go wrong with the removable route?

Dentures can become painful, damaged, loose, or unstable enough to click during speech. Very red or bleeding gums can occur alongside gum disease, fungal infection, or tooth decay.

[1][2]

What other ways can missing teeth be replaced?

A bridge is fixed to other teeth and cannot be removed. Dental implants are fixed to the jawbone and can support crowns or some dentures.

[2]

What is the choice really about?

The comparison begins with whether the replacement should be removable, fixed on implants, or a denture held by implants. Both fixed implant prostheses and implant overdentures have improved patient-reported outcomes in fully toothless patients.

[1][2]

Frequently asked questions

Can implant-supported teeth still be removable?

Yes. An implant overdenture is a denture retained or supported by implants, whereas a fixed implant-supported complete prosthesis remains fixed.

[1][2]
What if my denture starts slipping?

Slipping or clicking can mean the denture no longer fits properly; pain, wear, or damage are other problems that need attention.
