Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

If you’re considering a dental implant as a replacement for a lost tooth, you’re looking at a restoration method with an amazing 95% success rate after ten years. But that being said there’s still a risk, albeit quite low, the implant might fail.
And if you smoke, the risk is slightly higher. In a recent study of implant patients, twice as many of the failures occurred in smokers compared to non-smokers. If you’re a smoker, you can increase your chances of a successful outcome if you quit the habit.
Nicotine, a chemical within tobacco, is the primary cause for this higher risk. Besides its effect on the pleasure centers of the brain, nicotine also restricts smaller blood vessels that are abundant in the mouth and skin, causing less blood flow. As a result, the mouth doesn’t have as many antibodies and other substances available to fight infection and help traumatized tissues heal.
Because of this, as well as reduced saliva flow due to the habit, smokers have an increased risk of dental disease and are slower to respond to treatment. This can be especially problematic if the gum tissues around an implant become infected, which could lead to a catastrophic failure. Slower healing also impacts the post-surgery period when bone cells in the jaw are growing and adhering to the implant surface, forming a stronger bond.
To avoid these potential risks you should stop smoking before you undergo implant surgery. If you can’t completely kick the habit, you should at least stop a week before surgery and for two weeks after. It’s also critical that you practice good oral hygiene — both brushing and flossing — to minimize the occurrence of dental disease and see us for regular checkups and maintenance appointments.
Taking these steps will greatly increase your chances of being in the vast majority of people who continue to enjoy success with their implants for many years.

Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.
Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.
The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).
That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.
An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.
If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
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.
