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.

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.

You probably can’t remember a time without your teeth — and can’t imagine life without them. But now it’s a reality: one by one your teeth have become casualties in a long-standing war with dental disease until now they’re all lost.
Total tooth loss (edentulism) can be difficult in more ways than the loss of function — it can be psychologically traumatic as you must now transition from natural teeth to dentures or other restorations. To add to the stress, you probably won’t be able to obtain your permanent restoration immediately because the extraction sites must heal.
To help you with this transition and provide a means for you to have teeth during the healing period, we may fit you with an appliance known as an immediate denture. With these temporary teeth replacements, you can maintain your smile appearance, chew food and speak unimpaired.
Initially, immediate dentures should fit well, but over time your gums will tend to shrink as they heal. This can loosen the dentures’ fit and make them uncomfortable to wear. If the healing process is still ongoing and you still need to wear the immediate dentures, they can be relined with more denture material to fine-tune the fit.
At some point, though, we must consider creating a new, permanent set of dentures. When your mouth is fully healed, we can make a more accurate impression that we can then use to construct your new set. There are also other options, such as using dental implants to support a denture or a fixed bridge. This option will only be possible, however, if you have sufficient bone available to fully support it, which we might also be able to augment with grafting.
Immediate dentures serve a worthwhile purpose, but only for a temporary period. We’ll be happy to discuss all your options with you to help you find the right permanent solution that fits both your mouth’s condition and your financial ability.
