Implant retained dentures are dentures which are functionally assisted by dental implants.
There are a variety of reasons why people may not be able to wear a traditional removable denture.
Lower jaw: Losing your teeth leads to bone loss which continues over time. If a substantial amount of bone loss occurs, the lower jawbone may not be able to support a denture. Inserting two implants into the lower jawbone provides a solid foundation for a denture that otherwise a patient may not have been able to wear.
Upper jaw: Some people may not be able to wear traditional upper dentures because their jawbone has shrunk away with no ridge and insufficient palate depth to hold a full upper denture in place. Patients can also have a gag reflex which is oversensitive and they cannot tolerate the roof of their mouth being covered with a denture base. Having upper implants placed allows the size of the denture base to be reduced and made into an arch shape, rather than occupying the entire palate.
