One of the most common tissue reactions to a chronicallyill-fitting denture is the occurrence of hyperplasia of tissuealong the denture borders. Such hyperplasia of oral mucosa isnot restricted to this location but occurs in many areas wherechronic irritation of any type exists, such as on the gingiva,buccal mucosa, and angle of the mouth. Synonyms for denture induced hyperplasia are inflammatory fibrous hyperplasia, denture injury tumor, epulis fissuratum. Inflammatory fibrous hyperplasia as aresult of denture injury is characterized by the developmentof elongated rolls of tissue in the mucolabial or mucobuccal fold area into which the denture flange conveniently fits.1 This proliferation of tissue is usually slowin developing and probably is as much a result of the resorption of the alveolar ridge as of the trauma of the loose dentures. Inflammatory fibrous hyperplasia should he surgically excised, and either new denturesconstructed or the old dentures rebased to provide adequateretention.1
