Over extension of denture border is the main cause of denture-induced fibrous hyperplasia (DIH) especially with immediate denture. We report a 53-year-male with the chief complaint of a loose immediate maxillary denture as well as pain and discomfort during mastication and asking for new denture. Patient was examined and medical history was taken. Intraoral examinations revealed that folding with deep fissure covered by white granulation tissue in the maxillary right labial sulcus and left buccal sulcus related to the overextended thin denture borders and diagnosed as DIH. Treatment started with border adjustment and finally new denture fabrications. Exact Denture border extension verifications and adjustments during insertion is the most important step as well as patient education and periodic follow up after denture insertion for prevention of DIH occurrence.
