An overdenture is a removable denture that is fixed on natural teeth or dental implants. It is unlike a conventional denture, which rests on your gums without being attached to anything. There are three types of overdentures as outlined below:

  •    Implant-retained, gum supported

This type of overdenture rests directly on the gums and is held by implants fixed into the lower or upper jaw. It is secured to the implants with the aid of retentive attachments integrated into the denture. This type is the most common treatment for patients who have lost their teeth.

  •    Bar-retained, implant supported

This type of overdenture features retentive attachments on a metal bar. The bar attaches to the implants. The overdenture is secured to the bar using attachments screwed into the denture.

  •    Fixed, implant supported

This type of overdenture features the denture and bar as a one-piece structure screwed to the implants.  This overdenture functions most like your natural teeth as it doesn’t have flanges and doesn’t rest on the gums. It can only be removed by a professional.

Benefits of Overdentures

Overdentures have numerous benefits. Overdentures can prevent shrinkage of the jawbone and redistribute pressure in the mouth, which promotes stability of the dentures.

Overdentures can be particularly beneficial for you if you have any dental-related condition, such as oligodontia (missing at least six teeth), cleft palate, cleidocranial dysostosis, or Class III occlusion. They are better at improving dental function and retention compared to traditional dentures.

Traditional dentures typically become unstable over time and may need refitting. Overdentures are useful in preserving the surrounding bone and ensuring that you have a dental device that will stand the test of time.

Caring for Overdentures

If you have overdentures, it is imperative that you conduct proper oral hygiene. Otherwise, you may develop gum disease and cavities.

You’ll need to remove the dentures every night and clean the attachments in your mouth thoroughly. Be sure to follow your dentist’s instructions. It’s also important to schedule regular dental appointments for checkups and professional cleaning. Regular visits to the dentist ensure that you always have healthy gums and that the overdenture remains in good shape.
