An MDI mini implant is an implant used to provide better denture stability in patients that cannot handle standard implant surgery, do not have enough bone to support a standard implant or are going from one prosthetic system to another due to continuing therapy.

The top of an MDI implant is shaped like a ball that allows a rubber o-ring to snap in over the ball when the denture is placed onto it. These types of implants can usually be placed in one or two office visits because there is no waiting on the jawbone to heal. In most situations the patient can walk out with their dentures the same day they receive their implants.
