People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

Although dental disease prevention has made great strides over the last century, tooth decay and periodontal (gum) disease continue to pose a major health threat. People who’ve lost all of their teeth (edentulism) or most of them suffer the most with adverse effects on their overall health, function and appearance.
Removable dentures have been the traditional and most affordable means to treat edentulism. But even with material and construction advances in recent years, dentures can still lose their fit over time as the bone in the jaw shrinks. This happens because the bone no longer has the stimulus of natural teeth and older cells can’t be replenished at a healthy rate; the continuing compression of traditional dentures on the jaw’s bony ridges compounds the problem.
As the bone shrinks the dentures become loose and uncomfortable to wear. Among other results, this poor fit can drastically affect how you eat: studies of denture wearers have found a decrease in their diet’s nutritional value because they’re eating fewer vegetables or fibrous, “chewy” foods and more foods with refined carbohydrates and fats that are easier to eat but less nutritious.
There is an alternative, though, that might slow bone loss and provide a better long-term fit: an overdenture supported by dental implants. With this appliance, a few implants are strategically installed in the upper or lower jaw. Matched attachments securely fasten the denture to the implants. In this case, the implants not the jaw ridge and gums support the denture thereby preserving the bone.
If you’re healthy enough to undergo a tooth extraction, you should be able to handle implant surgery, a minor procedure usually performed with local anesthesia and with little to no discomfort afterward. It may even be possible to retrofit your current denture to work with the implants, but that will need to be determined during the planning stages.
Although more expensive than a traditional denture, overdentures are much more affordable than fixed restorations stabilized with implants. The difference, though, is the increase in your quality of life — for better nutrition, physical health and social confidence.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.
