Overdentures

An overdenture is defined as a removable partial denture or a complete denture that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants.

It is also known as overlay denture, hybrid prosthesis, telescoping denture or tooth supported denture.

Advanced periodontal or gum disease usually cause loose or painful teeth. If many of your teeth have become loose or painful, it may be too late for to save them. In such a situation, removing some of your teeth and replacing them with an overdenture may be the best way to avoid infection and restore function and health to your mouth.

Retention of any tooth for an overdenture preserves a portion of one of the major sensory inputs, for example input from the periodontal proprioceptors that respond to position and movement enabling better enjoyment of food.

Studies show that the use of an overdenture preserves the alveolar or jaw bone, especially in the area of retained teeth. With a regular denture, when all our teeth are removed, it causes bone in the jaw to recede. However, when an overdenture is placed, some of the natural teeth retained are used to anchor the denture. By leaving some of the roots of the teeth in place, bone loss can be significantly fended off bone loss and a more stable denture can be provided.
