The objective of the present study was to assess possible adaptive functional changes in the masticatory system after insertion of fixed prostheses supported by osseointegrated implants in the edentulous mandible. Registrations of mandibular movement characteristics and maximal biteforce were performed at insertion and after 1 week, 3 months and 1 year after connection. The duration of the opening and closing phase decreased and maximal biteforce increased significantly ( p ≤0.05–0.001) from connection of the prostheses to the annual check‐up. However, the process of functional adaptation implied2 identified stages. An immediate phase that occurred within the 1st week, probably due to altered impact from mechano‐sensitive receptors and a later more time‐dependent phase, based on learning and new cortical engrams. Accordingly, the process of adaptation will continue over a long period of time.
