Implant-Supported Dentures (Overdentures)

What are Implant-Supported Dentures (Overdentures)?

Implant-supported dentures, also referred to as overdentures, are dentures which anchor onto several dental implants. Implant-supported dentures are a great solution for denture wearers who want a more secure denture but can’t quite afford full mouth implant restoration or all-on-four teeth. Typically, 2 or 4 dental implants are placed in each arch to help anchor dentures in place. The denture locks onto these implants, as opposed to sitting on the gums, and is better secured in its place. Overdentures feel more secure as compared to traditional dentures. They rock less during chewing and talking and are geneally more comfortable. Here are some other benefits of overdentures: 


By placing just a few dental implants, you can better secure your denture in its place. Anchoring your denture onto dental implants can help you eat, chew and function better. Keep in mind, that overdentures are removable teeth, meaning that that they come in and out of your mouth. If you're interested in a non-removable, permanent treatment option, you should look into full mouth dental implants or all-on-four teeth instead.


Full mouth dental implant treatment options are very expensive, typically costing tens-of-thousands of dollars. On the other hand, implant-supported dentures cost only a few thousands dollars per arch, making them a much more affordable alternative. Overdenture treatment is much less costly as compared to other full mouth implant treatment options while still giving you a more secure and stable set of teeth.


Overdenture treatment is much simpler as compared to full mouth dental implants or all-on-four teeth. For instance, if you have weak jawbone, you still qualify for overdenture treatment but not for full mouth dental implants. Overdenture treatment only requires a few mini dental implants to anchor your dentures in its place and these implants can be placed just about anywhere. On the other hand, full mouth dental implant treatment usually requires extensive bone graft and sinus augmentation to prepare your jaws for multiple dental implants, making treatment much more complex.

How Many Dental Implants will I Need for Overdenture Treatment?

There are three common types of overdenture treatment options: 
  1. Two mini implants
  2. Four mini implants
  3. Four implants plus a supporting bar 
As you’d imagine, each subsequent treatment option provides more security for your dentures but also increases the cost of your treatment. The ideal number of dental implants required to secure your overdenture will depend on factors such as your bite forces, bone quality, anatomical structures, etc. Your dentist will examine your teeth and bite to recommend the ideal treatment option best suitable for you.
