Adsorptive denture, also known as full adsorptive denture, is a common clinical dental restoration that refers to a denture that is adsorbed to the alveolar ridge. It has the following characteristics: 1. The adsorptive denture is more stable and can protect the soft tissues. Compared with the traditional full denture, the impression edge of the adsorption denture is more fine, and it can achieve negative pressure attraction and stronger retention force when wearing it, therefore, it will be more stable when wearing it, and it will not be easy to pry, shaking and instability, which is also beneficial to the soft and hard tissues of the mouth. 2. Adsorption denture is more beautiful. Usually, the doctor will analyze the patient’s alveolar ridge very finely before lining up the teeth of the adsorption denture, so the shape of the teeth of the adsorption denture is more beautiful. 3. Adsorption dentures have a shorter fabrication period, usually within 2 to 4 weeks for a perfect restoration, avoiding the patient to bear the pain of missing teeth for too long.
