An overdenture is a prosthetic dental appliance that derives its stability from tooth roots or dental implants lying beneath them. The overdentures possess superior retention and stability, unlike the conventional dentures which are dependent upon the oral soft tissues for their support and retention, and tend to frequently slip while eating or talking.
Types of Overdentures
There are basically two types of overdentures:
- Root Supported Overdentures – these overdentures are supported by the underlying root canal treated teeth, which are reduced to a lower height so that they can support the dentures, but at the same time do not cause any hindrance during the insertion or removal of the prosthesis.
- Implant Supported Overdentures – in these overdentures, the main source of retention and stability is the underlying dental implants.
Who Should Get an Overdenture?

Steps Involved in the Fabrication of Overdentures
Steps involved in the preparation of overdentures depend upon the type overdenture that is being produced.
- Tooth Supported Overdentures – in these dentures, the process of fabrication is similar to the conventional dentures. However, the only difference is that the root canal treatment of the teeth that need to be embedded beneath the overdentures. After the root canal treatment, the teeth are ground to a height where they are able to support the prosthesis.
- Implant Supported Prosthesis – the only difference of implant supported prosthesis from the tooth supported prosthesis is that the dentures are supported and retained with the help of dental implants. These implants are placed at precise location in the jaw bone so that they are able to withstand the forces generated inside the mouth. Sometimes, precision attachments are also attached to the dentures which enhance the retention and stability of the dentures.
Benefits of Getting Overdentures
Thinking why you should prefer overdentures over the conventional dentures? Let's have a look at the benefits of getting overdentures:
- Improved Retention of the Dentures – one of the main problems of conventional dentures is that they frequently get dislodged while speaking or eating, and can lead to embarrassing situations for the wearer. On the other hand, the overdentures are more stable and retentive than the conventional dentures and eliminate the problem of denture slipping during use.
- Improved Chewing Capability – it is nearly impossible to eat anything hard with the conventional dentures as they are not stable enough. However, the overdentures allow you to eat anything you like, without any difficulty or discomfort.
- Enhanced Confidence – your overdentures will also boost your self-esteem since, unlike the conventional dentures, you don't have to worry about your dentures slipping whenever you speak.
