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.

For centuries, people who've lost all their teeth have worn dentures. Although materials in today's dentures are more durable and attractive than those in past generations, the basic design remains the same — prosthetic (false) teeth set in a plastic or resin base made to resemble gum tissue.
If you're thinking of obtaining dentures, don't let their simplicity deceive you:Â a successful outcome depends on a high degree of planning and attention to detail customized to your mouth.
Our first step is to determine the best positioning for the prosthetic teeth. It's not an “eyeball” guess — we make a number of calculations based on the shape and size of your jaws and facial features to determine the best settings within the resin base. These calculations help us answer a few important questions for determining design: how large should the teeth be? How far forward or back from the lip? How much space between the upper and lower teeth when the jaws are at rest?
We also can't forget about the artificial gums created by the base. How much your gums show when you smile depends a lot on how much your upper lip rises. We must adjust the base size to accommodate your upper lip rise so that the most attractive amount of gum shows when you smile. We also want to match as close as possible the color and texture of your natural gum tissues.
There's one other important aspect to manage: how your upper and lower dentures function together when you eat or speak. This means we must also factor your bite into the overall denture design. This may even continue after your dentures arrive: we may still need to adjust them while in your mouth to improve function and comfort.
Ill-fitting, dysfunctional and unattractive dentures can be distressing and embarrassing. But with careful planning and customization, we can help ensure your new dentures are attractive and comfortable to wear now and for years to come.
