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 ]

Estimated Enrollment: 80
Study Start Date: February 2010
Estimated Study Completion Date: November 2015
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 4 Imtec mini-dental implants (MDI)
4 Imtec MDI
Device: Imtec MDI
4 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.
