Overdentures are dentures that are supported by and attached to dental implants or root filled tooth roots. The implants and roots are utilised to increase the retention and support for the overdenture.
If you wish to have a root supported overdenture, we will need to check to make sure that you have the necessary number of root filled teeth of good quality. Also, it is important that the roots are free of infection by having good quality root canal treatments.
Due to their complexity, Overdentures are usually provided by dental specialists who are called Prosthodontists.
There are two types of implant supported Overdentures. These are ball-retained or bar retained. Which one a patient has will depend on their needs.
At least two dental implants are needed to provide enough support for an implant supported Overdenture. Usually, the dental implants for overdentures are placed in the front of the mouth. This is due to the fact, that most of the time, there is more bone in this area. Also a lack of vital structures such as nerves in the front of the mouth means that there is less likelihood of the dental implants causing complications.
Overdentures are great for patients who wish to have the benefits of dental implants but do not necessarily wish to go through bone grafting and gum grafting surgeries.
Root supported overdentures allow the remaining roots to stay in place. Therefore, the natural bone shrinking that occurs after root extractions does not happen.
Overdentures provide a large degree of stability and do not affect speaking and eating.
Although the time-frame can vary between individuals, it could take around two to six months for the installation of an overdenture.
An initial consultation will be provided to ensure a patient is a good candidate for the procedure. Following this, a cone beam CT scan may be carried out to make sure there is enough bone available and to ensure that sinus and nerves can be avoided during the implant process.
Implant placement will then be carried out. The patient will be provided with a temporary denture whilst implant-bone integration is taking place.
After 2-3 months, once implant integration has taken place, the overdenture is constructed and attached to the dental implants.
For the best results, patients should remove their overdentures at night and carry out good oral hygiene, denture and implant cleaning to ensure the fixtures stay in good condition for the long-term.
