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.
Stabilization of a Full Lower Denture
Edentulism in Lower Jaw
Lower Denture Made Within Last Few Years
Device: Imtec MDI
||Time Perspective: Prospective
||Clinical Evaluation of the Mandibular Mini-Implant Overdenture
Primary Outcome Measures:
- Success rate of mandibular overdentures supported by 4 MDIs placed in the interforaminal region in the long term. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Oral health-related quality of life and general satisfaction of patients. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

4 Imtec mini-dental implants (MDI)
4 Imtec MDI
Device: Imtec MDI
4 Imtec MDI
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.
