    Abstract

    To obtain denture retention, support, and stability in Class III edentulous cases with flat alveolar ridges and extensive flabby tissue is very difficult. The patient was a 72-year-old male who wore ill-fitting 20 year old dentures made by non-medical institutions. There was flabby tissue on the maxillary anterior ridge. The patient showed Angle Class III skeletal relationship with severe protruded mandible. First, temporary dentures were fabricated to restore the masticatory function, and final dentures were made through non- pressure impression technique and careful the arrangement of the posterior resin teeth. Improvement of the retention and stability of the denture during the occlusal force application is reported.
