Brief Summary:
Stabilization of existing full lower dentures by means of mini-dental implants (MDI). To test whether 4 mini-implants placed at the front of the lower jaw can stabilize an immediately-modified existing lower denture.

Condition or disease Intervention/treatment
Stabilization of a Full Lower Denture Edentulism in Lower Jaw Lower Denture Made Within Last Few Years Device: Imtec MDI

Detailed Description:
To test whether the percentage of case successes of these lower dentures supported by 4 MDIs is equal to or greater than 95% at 1 year. Success is defined as a denture supported by implants that is functioning in the way it was intended.
