What is an implant supported overdenture?
Jaw bones wear out gradually. This wearing out of jaw bone is higher in lower jaw. As a result, jaw height reduces to the level of or below that of tongue.
This seriously disturbs denture stability as any tongue movements tends to move denture.
Implants can be a ray of hope in such conditions. They are placed inside the jaw bone and extensions called abutments are fixed over these implants. These extensions hold the dentures firm in their position. The comfort achieved is much better.
Implant supported dentures provide comfort and confidence to patients who otherwise would suffer from loose dentures and embarrassment.
Based on the quality and quantity of jaw bone available, implants are placed are placed in the jaw bone at suitable site and are allowed to heal. After 3-6 months, abutments are fixed and components are fixed onto the under surface of dentures. These get connected to each other in the form of lock and key and hold dentures firm in their place.
These implants also preserve bone around them thus improving the longevity and comfort of dentures.
