DentureswithImplantsCouldHelpYouAvoidBoneLoss

Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.

But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.

Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.

But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.

The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.

The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.

If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

Implant-BasedRemovableDenturesaGoodChoiceforPatientswithExtensiveBoneLoss

People who’ve lost all their teeth (a condition known as edentulism) face a decision on how to restore their lost function and appearance. And there are a number of options to consider.

A fixed bridge supported by dental implants, for example, is a good choice for patients who still have sufficient bone structure in their jaw. It’s not a good choice, however, for those with the opposite situation — who’ve experienced significant bone loss which has also affected their facial structure. For them, there’s a better alternative that also uses implants for support — the overdenture.

An overdenture is similar to a traditional denture, in that it’s made of life-like crowns permanently set in denture plastic, and may either partially or fully cover the roof of the mouth. The main difference, though, is that unlike traditional dentures which rest for support on the gum ridges, an overdenture is supported by strategically placed implants that the denture fits over and connects to — hence the name “overdenture.”

There are a number of advantages for an overdenture, especially for patients with bone loss. A removable, implant-supported denture can be designed to replace lost tissues that have altered facial appearance — to “fill in” the face and restore aesthetic harmony. Patients who’ve previously worn dentures will also often find their speech better improved than with fixed bridgework.

Because it’s removable, an overdenture and the underlying gums are easier to clean, which helps inhibit disease and lessen further bone loss. It also allows you to properly care for the denture, which can extend its longevity and reduce future potential maintenance and replacement costs.

If you would like to consider removable overdentures as an option, you should begin first with a thorough oral exam that includes evaluating the status of your bone, jaw and facial structure. From there we can advise you if overdentures are the best choice for you.
