Implant Supported Overdenture

Implant Supported Overdenture

Implant retained overdenture Implant-retained overdenture is also called snap-on denture or snap denture. It requires 2-4 implants per jaw to support and retain all teeth. The advantage is it is easy to maintain and keep hygienic. The disadvantage is that it is still removable, which requires the user to remove it each night and clean after meals. A correctly and precisely made implant overdenture should fulfill the standard of health, function, and esthetics.

Mr. A presented requesting full mouth rehabilitation. He worried that his only four implants (two in the top jaw and two in the lower jaw) are not enough to give him a stable and retentive denture. Based on the current evidence, Dr. Qing suggested that the current implants might give enough retention. We can take this conservative approach and start making the overdenture with the contingency plan to add more implants in the future while still being able to use the current denture without redoing it.

Straumann NovaLoc system which engages the locator abutment is used to retain the upper and lower overdenture.

The final smile (side view) shows the facial support from the teeth to give the patient a younger-looking appearance.

The video of the final results is shown in Dr. Qing's Youtube channel. https://youtu.be/Ra1bRSQJ968
