MDI implants can be installed in a single office visit.
Mini dental implants (MDIs) refer to a system for affixing dentures by implanting a titanium screw into the jawbone. Once installed, MDIs keep false teeth in place with the right tension for everyday activities.
Technology
The MDI system consists of tiny screws made of titanium measuring between 1.8 mm and 2.9 mm in diameter and 10 mm to 18 mm in length. At the top of the MDI is a protruding ball on which the denture's metal housing is affixed by an O-ring. The MDI holds the denture in place yet still allows it to be removed and reinstalled.
Installation
Using a tiny drill bit, the technician makes a hole through the gum line and jaw bone into which the MDI is inserted. The MDI is threaded, seating itself in the jawbone as it is gradually inserted. Installation may or may not require making an incision in the gum line based on patient-specific conditions. The process takes about 90 minutes, does not require general anesthetic and allows the patient to eat the same day.
Prognosis
In 1999, the Food and Drug Administration (FDA) approved MDI implants for permanent use. With proper cleaning and care, the system is designed to be a long-term solution for most patients.
