Conventional full dentures are used to replace a full set of teeth either on the upper or lower jaw. When all of the patient’s natural teeth have been removed and the gum tissues have healed, conventional full dentures may be placed in the mouth. In between, the patient may be fitted with an immediate denture that can be inserted on the same day the teeth are extracted. Using immediate full dentures is beneficial for the patient because this means that he does not have to go without teeth for a certain period. Readjustment of the dentures will have to be made after several months because the supporting bone will reshape as it heals and this will cause the denture to loosen.
Generally speaking partial dentures tend to be held in place by the presence of the remaining natural teeth and complete dentures tend to rely on muscular co-ordination and limited suction to stay in place. The maxilla very commonly has more favorable denture bearing anatomy as the ridge tends to be well formed and there is a larger area on the palate for suction to retain the denture. Conversely, the mandible tends to make lower dentures much less retentive due to the displacing presence of the tongue and the higher rate of resorption, frequently leading to significantly resorbed lower ridges. Disto-lingual regions tend to offer retention even in highly resorbed mandibles, and extension of the flange into these regions tends to produce a more retentive lower denture. An implant supported lower denture is another option for improving retention.
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
