Functional adaptation of the masticatory system to implant-supported mandibular overdentures.

Objectives: The purpose of this study was to investigate the adaptation behavior of the stomatognathic system after immediate loading (24 to 72 h after surgery) of two implants supporting mandibular overdentures, assessed on insertion and three months later. The study hypothesis was that insertion of the overdentures would significantly change masticatory performance and muscle activity at both times.

Material And Methods: Thirty subjects (nine female, mean age 69.
