What makes the full denture successful?

Having removable dentures is probably something, which each patient would love to avoid. It is probably the most uncomfortable prosthetic device used in dentistry. The complete dentures sit on the jaw ridges (places where teeth used to be), covered by the gums. The more retentive and more stable the denture is, the more comfortable it feels. There are two types of gum tissue in the mouth. “Attached gum”-is gum tissue attached to the bone through periosteal, which is not mobile, and “detached tissue” or “mobile tissue”- gum tissue that is not directly supported by the bone and moves during certain functions (such as speech, mastication etc.). In order for the full denture to be more retentive (hold better), we have to use maximum available surface for the denture to adhere. To achieve this, complete dentures should cover the area of the mouth covered with attached gum, and it borders should be at the line where attached and detached gingiva meet. This allows us to use maximum of surface for denture adhesion, and prevents the complete denture from dislodging by mobile part of the gum.

The full upper denture covers the whole palate, making an air-tight zone (similar to rubber suction cup on the glass). Usually with the complete upper dentures we can get a pretty good suction and retention due to the large surface area of the denture base. Nevertheless, there are some people, who have a high gagging reflex. In those cases we have to shorten back border of the denture or even cut out the palate portion of the denture all together.

The full lower denture is the one where most of the people have tremendous problems. The anatomy of the lower jaw does not allow us to get a good suction of the denture. The fact that the lower jaw is the mobile bone (we move it constantly speaking, eating, swallowing) and because there is not much of the attached gum on the bottom, it makes it almost impossible to get good retention on the lower jaw.

How long my dentures will last?

Dentures are supported in the mouth by the bone ridge of the jaw. The only thing, which prevents the ridge of the jaw from resorption, is presence of the teeth (or implants). Obviously if you have complete dentures there are now teeth, preventing the bone from resorption. As the bone disappears, spaces become to appear between the denture and the gum. Dentures start to fit looser and looser. Because of the empty spaces formed between the gums and the denture, and the complete denture, loses support in some spots, breakage of the base of the dentures becomes more of the concern. The dentures start to disappear under lips, reducing the distance between the tip of the nose and the tip of the chin, “closing you bite”. As the result of denture instability and constant moving the flabby, mushy gum tissue starts to form under the base of the denture, causing more and more discomfort and pain and making dentures looser and looser.

Even though each patient is different and the levels of bone changes under the dentures will vary from person to person, it is general recommendation to have your dentures relined every two years and change the dentures every 5-7 years.
