Effect of intramobile mechanism for osseointegrated implants on nobility, occjusion and masticatory function

Abstract

I investigated how different methods of fixing the superstructure over osseointegrated implants influenced the stomatognathic system. Six subjects with IMZ implants and 20 normal subjects were studied. The superstructure on each implant was either an intramobile element, an intramobile connector, or a titanium element. Mechanical mobility of each implant was measured with a tooth nobility tester, and occlusal contacts were determined with the add-picturesystem. Muscle activity of the masseter, anterior temporal and anterior belly of the digastric muscles was evaluated by electromyography. The results suggest that the intramobile mechanism affects mobility, occlusal contact and masticatory function.
