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.

Many people with diabetes are hesitant about getting dental implants because they’re under the impression their chances of failure are greater than for non-diabetics. But if you’re one of the 26 million Americans with diabetes, that isn’t necessarily so — with a little extra precaution before, during and after implant surgery.
Diabetes is a group of diseases that affect how the body processes glucose. This simple sugar is used by the body to provide energy to cells, but can also cause damage if its volume level in the bloodstream is too high. The body normally regulates this through the hormone insulin produced by the pancreas.
The pancreas in people with Type 1 diabetes doesn’t produce insulin and so they must receive an outside source of the hormone through daily injections with careful daily monitoring of glucose levels. Those with Type 2 diabetes, the most common form of the disease, don’t produce a sufficient amount of insulin or the body no longer responds to the insulin produced. For either type, abnormal glucose levels — either too high or too low — can have adverse affects on the body, including blindness, nerve damage, gangrene, coma or death.
Diabetes can also slow wound healing, increase the risk of infection, and alter the body’s inflammatory response, all of which are major concerns when placing implants. Because implant placement involves minor surgery in which a wound results, there’s been wide concern that a slower healing process could increase the risk of implant failure.
Recent studies, though, are encouraging especially for patients who have their diabetes under control through medication, diet and exercise. Patients with poor glucose control are at higher risk, because it can take longer for the bone to heal around an implant after placement. For such individuals special considerations to guard against infection may be needed during implant surgery.
In fact, the implant success rate for most diabetics is about the same as for non-diabetic patients, 95%. With proper disease management and a little extra wound care, you can be among the many that experience a favorable outcome and a more attractive smile with dental implants.
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.

You’ve probably heard a lot about dental implants as replacements for missing teeth. So, why are they so popular with both patients and dentists? While other restorations can mimic the color, shape and texture of natural teeth, dental implants have one clear advantage — and it’s all about the bone.
The bone in your jaws provides stability and structure for teeth — without it and the intricate system of gum tissue attachments teeth couldn’t survive the normal biting and chewing forces they encounter every day. That’s why bone health is crucial for maintaining tooth integrity.
Teeth also help bone to remain strong and healthy. The forces we generate as we chew transmit through the tooth roots to the bone, which stimulates continuing growth. If a tooth is missing, however, the bone around it doesn’t receive this stimulation and may begin to lose some of its volume and density — up to a quarter of its width in just the first year after tooth loss.
This bone loss continues even with other restorations because they’re not able to stimulate bone growth. But dental implants can. This is because the portion of the implant imbedded into the bone is constructed most often of titanium, which has a natural affinity toward bone. Bone cells are naturally attracted to titanium and will begin to grow and attach to the metal surface, a process known as osseointegration.
Through osseointegration, the implant develops a durable bond with the jawbone a few weeks after surgery that surpasses other restorations, and is a prime reason for their success rate. Although installing implants can be an expensive undertaking, their proven longevity may result in less maintenance, repair or replacement costs over time than other replacement options.
If you’re considering dental implants, remember it’s what you can’t see beneath the attractive crown that makes them special. And it’s a choice you can depend on to provide you a beautiful smile for years to come.

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.
