Although teeth are quite durable, we can still lose them—even all of them—to disease or injury. The good news, though, is that we have effective ways to restore teeth after they're lost. One of these, the removable denture, has given people their teeth back for several generations. And with recent advances in technology, today's dentures are even better.
Although more advanced, today's dentures share the same basic structure as those from a century ago: prosthetic (false) teeth set in a plastic resin colored to resemble the gums. The traditional denture is molded to fit snugly over an individual patient's alveolar jaw ridges, which once supported the former natural teeth. The denture stays in place primarily through a suction effect between the denture and the ridges.
Modern technology, though, has greatly improved today's dentures. Digital imaging can be used to generate highly accurate impressions of the dental ridges that can lead to denture bases with better fit. Dentists using photographs of the patient, especially in earlier years, are better able to identify facial landmarks, which enables them to position the new teeth to more closely recreate the patient's former smile.
These technological aids now help dentists to create more attractive dentures with better support and comfort. But the fit that makes this possible may not last due to a particular weakness inherent in traditional dentures—continuing bone loss. When teeth are missing, the underlying jawbone can lose bone volume over time. Dentures don't stop this process and can accelerate it due to constant friction and pressure on the dental ridges.
But a new modification incorporating dental implants with dentures can help solve these problems. By placing a few strategically positioned implants in the jawbone that then connect with the denture, the appliance not only gains more stability, but also produces less pressure on the dental ridges. In addition, bone cells naturally grow and adhere to the titanium implant posts, which helps to stop or slow bone loss.
If you've experienced total tooth loss, dentures are an affordable and effective option. Thanks to modern dental advances, you can get back the smile and dental function you once lost.

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.

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.
