Title Mini Dental Implants: Approved for Long-Term Fixed and Removable Prostheses
Clinical Question For complete/partial edentulous patients that will receive an implant-supported prosthesis, is the longevity of mini dental implants comparable to conventional dental implants over a 5-year period?
Clinical Bottom Line With a somewhat greater implant-to-tooth ratio for fixed restorations versus removable prostheses over a mean follow-up of 2.9 years, mini dental implants have shown comparable longevity to conventional dental implants. (See Comments on the CAT below)

Key resultsOver a 5-year period, 2514 MDI’s (mini dental implants) were placed in 531 complete/partial edentulous patients. An overall implant survival of 94.2% was observed with a mean follow-up of 2.9 years (a rate comparable to conventional dental implants over the same period). There were 145 failures defined as implants with mobility, persistent subjective complaints, or infection with suppuration. Splinted implant mobility was assessed without removal of fixed prostheses. Implant survival improved with placement experience.

The Evidence
Patient inclusion for the study was broad, excluding only patients with severely atrophic bone or active intraoral infections. MDI’s were placed in near equal proportions in the maxilla and mandible, in males and females, and in fixed and removable prostheses. More MDI’s were placed in some applications than would be expected with conventional implants. Evaluation of individual implant survival in splinted prostheses by evaluating the prosthesis mobility may overstate implant success to some extent. No implant life table was provided. 20 implants fractured during placement and were not included in the survival analysis. The mean 2.9 years of follow-up is ample to assess initial integration, but relatively short for assessment of failures associated with chronic load. No treatment or analysis bias was in evidence, but the principal author/clinician disclosed financial interests in MDI use.
Applicability This evidence provides a valuable insight into the potential use of MDI’s for complete/partial edentulous patients.

Nice CAT. The use of the mini implants can be beneficial to elderly patients who have limited resources and to keep the surgical insult to a minimum.
