Abstract

In patients with severely resorbed alveolar bone, it is difficult to gain retention in denture. Lack of retention makes denture unstable and lead to trouble in using denture. Suction denture seals the entire denture border with movable mucosa and this sealing mechanism forms negative pressure beneath the denture and produce higher retention and stability to denture. In this case, 4 edentulous patients visited for lack of retention with dentures. Considering their high expectation with retention, suction denture concept was used to fabricate retentive and stable denture. The purpose of this case report is to compare and analyze the considerations of suction denture restorations in edentulous patients.
