Overdentures

If you would like to have an implant supported overdenture, our dentist will need to ensure there is enough bone left to place the implants, which are most commonly provided in areas where traditional fixtures are less stable.

If you wish to have a root supported overdenture, we need to check to make sure that you have the necessary number of roots of good quality and they are uninfected.

How does an overdenture work?

Depending on your oral condition our dentist will offer one of two types of implant-supported overdenture: either ball-retained or bar-retained. Both types are manufactured from an acrylic base which is designed to look like gum, alongside porcelain or acrylic teeth to give a natural tooth appearance.

In addition, the two types of implant retained overdentures need at least two dental implants to be installed in the jawbone in order to provide enough support for the overdenture.

Ball-retained overdentures possess a socket that is attached to up to five implants that have been placed in the mouth. Alternatively, bar-retained dentures include a thin metal bar that follows the curve of the jaw, with the dentures held in place by fitted clips.

The implant over denture is  placed in the anterior region of the mouth because most of the time there is more bone in this area, even if teeth have been missing for a long period of time. Similarly, a lack of vital structures such as nerves in the front of the mouth means that there is less likelihood of the dental implants impinging on any vital structures.

Benefits of Overdentures:

Overdentures are great for patients who wish to have the benefits of dental implants but do not necessarily wish to go through the bone grafting and gum grafting surgeries that are usually required for multiple single implants, or do not wish to incur the time and costs involved with having multiple dental implants.

In the case of root supported overdentures, the advantage of not removing the remaining roots from the mouth is that they allow proprioception to remain. The jaw bone to and the roots remain, preventing the potential shrink away which is the case with complete dentures. The jaw bone can then be used in future for the installation of dental implants should that be required.

Contrasting to traditional procedures, overdentures are more stable because they are attached to and supported by the installation of dental implants in the jawbone. Therefore overdentures have far better success compared to complete dentures.

This means that people who were previously concerned about their dentures falling out or becoming loose can experience security and the improved quality of life as a result. Overdentures also help people to communicate properly and with confidence as they are securely fitted.

How long does the overdenture procedure take?

Although the timeframe can vary between individuals, it could take around three to six months including implant surgeries and the installation of the overdenture.

How does the treatment work?

Patients will be asked to attend an initial consultation before the start of the treatment to ensure they qualify to receive overdentures. During this appointment, our dentist will review medical and dental records, and take X-rays and impressions of the teeth to allow models to be created by the laboratory.

Following this, a cone beam CT scan may be carried out to ensure there is enough bone available to install the dental implants, as well as to establish the exact location of the sinuses and nerves so they can be protected throughout the procedure.

With the entire process taking around four visits to complete, our dentist will create a temporary denture to be worn throughout, which is ideal for people who are worried about their appearance.

The first surgery will involve the placement of the implants in the jawbone, where an incision is made in the gum in order to place the implants.

Following the initial procedure, it is vital to avoid putting pressure on the newly installed implants to speed up healing and limit the feeling of discomfort.

After the healing process is complete and the implants have fused with the jawbone, the second surgery can be carried out.

During this simple procedure, the tops of the implants are revealed by making a small incision into the gums where a healing collar is placed. This ensures that the gum heals in the correct manner to make room for the fixture of the overdentures.

In the final stage of the process, the teeth are secured into the overdenture framework, creating a completely new smile for the patient.

How do I take care of Overdentures?

For the best results, patients should remove their overdentures at night and carry out good denture cleaning to ensure the fixtures remain in good condition for the long-term. The implants should also be cleaned on a regular basis to prevent the onset of infection.

Patients should attend regular check-ups following the installation of their overdentures to ensure that any routine maintenance treatment required is carried out when necessary.
