Complete denture fabrication of edentulous patient withsevere alveolar bone resorption using suction mechanism: A case report

  • 1Department of Prosthodontics, School of Dentistry, Chonnam National University, Gwangju, Republic of Korea


Fabrication of complete denture with suction mechanism was introduced to enhance the retention and stability of denture by sealing around the denture border by forming negative pressure on the inner side of denture base during functional movement such as swallowing or masticating. Mandibular suction dentures reduce denture dislodging force during opening by taking preliminary impression without pressure on retromolar pad area in rest position. In this case, fabrication of complete denture using suction mechanism for an edentulous patient with severe alveolar bone resorption allowed us to clinically enhance retention and stability of denture and improve satisfaction of patient.
