Implant-SupportedDenturesCouldImproveYourBoneHealth

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.

Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.

While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.

But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.

Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.

There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.

The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.

While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

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.
