Jun, Yang, Vang, Yang, Park, and Yun: Complete denture fabricated by Jiro Abe's method for edentulous patient with severe alveolar ridge resorption: a case report

Abstract

Fabrication of complete denture by Jiro Abe's method was introduced that enhance the retention and stability of denture by sealing around the denture border with mucous membrane to make negative pressure at the inner surface of denture base when swallowing or occlusion. In this case, taking impression and fabricating complete denture by the Jiro Abe's method for an edentulous patient with severe mandibular alveolar bone resorption allowed us to obtain clinically enhance stability of denture and improve satisfaction of patient.
