Abstract

In a completely edentulous patient who cannot have implant-retained overdentures due to medical history and economic circumstances, a suction-effective complete denture utilizing the closed-mouth impression technique is being used to secure high retention. In this case, both a conventional complete denture using the open-mouth impression technique and a suction-effective complete denture using the closed-mouth impression technique were fabricated for a single completely edentulous patient. The results demonstrated that both methods provided excellent outcomes in terms of function, esthetics, and patient satisfaction. Conventional complete dentures increase the area of denture-bearing pressure to ensure retention and stability, whereas suction-effective complete dentures achieve retention by sealing the entire border of the denture. Since there are characteristic differences in the clinical and laboratory procedures due to differences in the concept of denture fabrication, this was compared through this case report.
