Dentures are removable appliances that can replace missing teeth and help restore your smile. If you’ve lost all of your natural teeth, whether from gum disease, tooth decay or injury, replacing missing teeth will benefit your appearance and your health. That’s because dentures make it easier to eat and speak better than you could without teeth—things that people often take for granted.
Cheap dentures, on the other hand, refer to both the quality and the cost of the dentures. Usually, when you go for the cheap dentures, the dentures themselves carry a small price tag but they end up costing you more in the long run for maintenance and frequent relining (refitting). Add to that the fact that you will probably have days and weeks of discomfort to endure.
Retention is the principle that describes how well the denture is prevented from moving vertically in the opposite direction of insertion. The better the topographical mimicry of the intaglio (interior) surface of the denture base to the surface of the underlying mucosa, the better the retention will be (in removable partial dentures, the clasps are a major provider of retention), as surface tension, suction and friction will aid in keeping the denture base from breaking intimate contact with the mucosal surface. It is important to note that the most critical element in the retentive design of a maxillary complete denture is a complete and total border seal (complete peripheral seal) in order to achieve 'suction'. The border seal is composed of the edges of the anterior and lateral aspects and the posterior palatal seal. The posterior palatal seal design is accomplished by covering the entire hard palate and extending not beyond the soft palate and ending 1–2 mm from the vibrating line.
Note: In addition or as an alternative to commercial cleansers, dentures can be cleaned with toothpaste or soap—mild hand soap or dishwashing liquid—warm water and a soft-bristle toothbrush. However, denture wearers should never use bleach or powdered household cleansers, which can be abrasive, for cleaning their appliance as this may damage the denture.
