MDI mini implants were developed in order to provide greater denture stability for those patients who
1) cannot withstand the rigors of conventional dental implant surgery,
2) do not have enough bone to allow full-size implants to be placed, or
3) are in on-going therapy from one prosthetic system to another.
The head of the MDI mini implants is shaped like a ball, and the retaining fixture acts like a socket that contains a rubber O-ring. The O-ring snaps over the ball when the denture is seated and holds the denture at a predetermined level of force.
Mini-implants can generally be placed start to finish in one to two visits. There is no waiting time for the bone to heal. In many cases mini implants are placed and the patient walks out with their dentures secured on the same day.
