When dentures fail to stay in place, the problem can be traced to several key biological and mechanical factors: 1. Alveolar Ridge Resorption: After tooth loss, the jawbone naturally shrinks. As the ridge flattens, the denture loses its anatomical foundation and begins floating. 2. Compromised Peripheral Seal: If the border of an upper denture is too short, too long, or chipped, air enters beneath the plate, breaking the suction seal instantly. 3. Xerostomia (Dry Mouth): Natural suction relies on a thin film of saliva to create surface tension between the acrylic base and mucosal tissue. Without adequate saliva, dentures will not stay seated. 4. Occlusal Disharmony (Uneven Bite): If the artificial teeth do not meet evenly when chewing, one side will lever the other side loose. 5. Hyperactive Tongue or Facial Muscles: In the lower jaw, tongue movement easily lifts unweighted or poorly contoured lower plates. What Denturaa offers: Denturaa resolves retention issues using digital impression scanners, anatomical articulators, and specialized suction border moulding.
