IMPLANT SUPPORTED DENTURES
Implant Supported Dentures ( Overdenture )
An implant-supported denture is a type of overdenture that is supported by and attached to the implants. A regular denture rests on the gums, and is not supported by implants.
An implant-supported denture is used when a person doesn’t have any teeth in the jaw, but has enough bone in the jaw to support implants. An implant-supported denture has special attachments that snap onto attachments on the implants.
Implant-supported dentures usually are made for the lower jaw because regular dentures tend to be less stable there. Usually, a regular denture made to fit an upper jaw is quite stable on its own and doesn’t need the extra support offered by implants. However, you can receive an implant-supported denture in either the upper or lower jaw.
You should remove an implant-supported denture daily to clean the denture and gum area. Just as with regular dentures, you should not sleep with the implant-supported dentures at night. Some people prefer to have fixed (permanent) crown and bridgework in their mouths that can’t be removed. Your dentist will consider your particular needs and preferences when suggesting fixed or removable options.
How Does It Work?
There are two types of implant-supported dentures: bar-retained and ball-retained. In both cases, the denture will be made of an acrylic base that will look like gums. Porcelain or acrylic teeth that look like natural teeth are attached to the base. Both types of dentures need at least two implants for support.
- 1.Bar-retained dentures — A thin metal bar that follows the curve of your jaw is attached to two to five implants that have been placed in your jawbone. Clips or other types of attachments are fitted to the bar, the denture or both. The denture fits over the bar and is securely clipped into place by the attachments.
- 2.Ball-retained dentures (stud-attachment dentures) — Each implant in the jawbone holds a metal attachment that fits into another attachment on the denture. In most cases, the attachments on the implants are ball-shaped (“male” attachments), and they fit into sockets (“female” attachments) on the denture. In some cases, the denture holds the male attachments and the implants hold the female ones.

Overdenture Treatment process
- Oral examination , Consultation , CT scan ( 3D images X-RAY ) , Treatment planning
During the exam, the dentist will review your medical and dental histories, take a computed tomography (CT) scan of your mouth. This shows where your sinuses (located above your upper teeth) and nerves are. It allows the dentist to make sure they will not be affected by the implant placement. A CT scan also may be done to see how much bone is available and to determine the best locations for the implants.
2. Dental implant placement – The implants are usually placed in the jawbone at the front of your mouth because there tends to be more bone in the front of the jaw than in the back. This usually is true even if teeth have been missing for some time. Once you lose teeth, you begin to lose bone in the area. Also, the front jaw doesn’t have many nerves or other structures that could interfere with the placement of implants. The number of implants placed is dependent on bone condition and the implantologist judgement. Mostly 2 – 4 dental implants post are used for one arch.

Caring for Implant-Supported Denture
You will need to remove the denture at night and for cleaning. You also should carefully clean around the attachments.
Your dentist will test all the parts of your new denture to see if they are secure. Even though your denture is stable, it still can move slightly when you chew. This slight movement can cause the denture to rub against your gums, which can cause sore spots. Your dentist will check your gums and also will check the way your top and bottom teeth come together (your bite) after insertion of the denture.
The clip or other attachments on the bar-retained denture usually will need to be replaced every 6 to 12 months. They are made of a plastic material (nylon) and will wear after continued use.
What Can You Expect From Your Implant-Supported Denture?
- Your implant-supported denture will be more stable than a regular denture. You will find it easier to speak and you won’t have to worry about the denture becoming loose or falling out of your mouth. You generally will be able to eat foods you could not eat before. However, you will not be able to chew hard or sticky foods because they can damage the denture.
- If you have an implant-supported denture in your upper jaw, it can be made to cover less of your palate (roof of your mouth) than a regular denture. That’s because the implants are holding it in place instead of the suction created between the full denture and your palate.
