Suction dentures, also known as suction-type complete dentures, are an advanced removable prosthetic solution for fully edentulous patients. They rely on a well-designed polished surface, accurate border molding, and close-fitting base to create stable negative pressure between the denture base and oral mucosa, providing strong retention without clasps or implants.
Compared with traditional complete dentures, suction dentures offer significantly better stability and chewing efficiency, reducing slipping, pain, and food impaction during speaking and eating. Their success depends heavily on precise impression taking, ideal jaw relation recording, and meticulous adjustment of occlusion and peripheral sealing.
Suitable candidates include patients with good alveolar ridge conditions, healthy mucosa, and acceptable manual dexterity. Those with extremely resorbed ridges, dry mouth, or poor oral hygiene may need alternative treatments such as implant-supported overdentures.
Manufacturing often integrates digital workflows, including intraoral scanning, CAD/CAM design, and 3D printing, improving fitting accuracy and shortening production time. Proper maintenance, such as daily cleaning, regular check-ups, and timely relining or rebasing, extends service life and enhances long-term comfort.
As a cost-effective and minimally invasive option, suction dentures have gained wide acceptance in clinical and laboratory settings worldwide, especially for elderly patients seeking improved quality of life with stable and functional removable prosthetics.
