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-SupportedDenturesCouldHelpYouAvoidBoneLoss

Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.

Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they're replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.

Removable dentures can't provide this stimulation. In fact, the pressure generated as they compress the gums' bony ridges can even accelerate bone loss. That's why over time a denture's fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.

In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.

Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant's hold in the jaw.

Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.

Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.
