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.
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.
Gum disease is caused by plaque and may result in tooth loss without proper treatment. Symptoms and signs of gum disease (gingivitis or periodontal disease) include receding gums, bad breath and pocket formation between the teeth and gums. Treatment depends upon the stage of the gum disease, how you responded to earlier treatments, and your overall health.
There are three main ways to replace missing teeth. The first is with a removable false tooth (or teeth) - called a partial denture. The second is with a fixed bridge. A bridge is usually used when there are fewer teeth to replace, or when the missing teeth are only on one side of the mouth. The third way is by the use of dental ‘implants'. This is where an artificial root is placed into the bone of the jaw and a crown or bridge placed on top of this. See our leaflet ‘Tell me about: dental implants'.
Denture adhesives, also called denture adherents, are creams, powders, wafers or strips that are used to hold dentures firmly in place. The adhesive also helps form a seal that keeps food particles from sticking between the dentures and gums. Adhesive is applied to clean dentures, which are then positioned in the mouth and held in place for a few seconds, according to the manufacturer’s instructions.
Sulphamic acid is a type of acid cleanser that is used to prevent the formation of calculus on dentures. Suphlamic acid has a very good compatibility with many denture materials, including the metals used in denture construction.[32] 5% hydrochloric acid is another type of acid cleanser. In this case, the denture is immersed in the hydrochloric cleanser to soften the calculus so that it can be brushed away. The acid can cause damage to clothes if accidentally spilt and could cause corrosion of cobalt-chromium or stainless steel if immersed in the acid often and over long periods of time.[32]
The Premium Denture is very high in natural appearance. It features enhanced natural appeal, wear and stain resistance, with detailed customization. As with the UltimateFit and EconomyPlus Dentures, the Premium’s extra-high density teeth are first set in wax for you to try in. Changes may be made at that time. After you have approved the look of your Premium Denture, the lab will custom finish your denture in the permanent acrylic base material. This additional customization results in a more natural look.Affordable Dentures in Houston, TX
