Further study details as provided by 3M:

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 ]

Secondary Outcome Measures:
  • Oral health-related quality of life and general satisfaction of patients. [ Time Frame: 3 years ]

Enrollment: 80
Study Start Date: February 2010
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
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.
