CouldaDentalBridgeBeaBetterChoiceThanImplants

What a difference forty years can make: Dental bridges once occupied the top spot for choices to replace missing teeth until the arrival of dental implants in the 1980s. Today, dental implants are the gold standard for dental restoration.

But although bridgework may have lost “first chair” in the orchestra of restorations, it's still a viable option. In fact, it can be the best option in certain situations.

Bridges consist of a series of porcelain crowns fused together like fence pickets. The center crowns, known as the pontics, “bridge” the gap left by a missing tooth or teeth. The crowns on each end, the abutment teeth, crown the natural teeth on either side of the gap to support the bridge.

Bridges are effective and durable, but with a major downside: To accommodate the abutment crowns, we must reduce the size of the natural teeth to which they'll be attached. This alteration can weaken those teeth's structure and require them from then on to have some form of restoration. They're also at higher risk for tooth decay.

Implants, on the other hand, don't require this alteration, and may also be more durable than bridges. Why then consider a bridge?

Price can be a factor: Implants may be more expensive, especially involving multiple teeth. Keep in mind, though, that this only compares the initial cost: Because implants have a 95% or more ten-year success rate, with further evidence they could potentially last for decades, they may actually cost less in the long-run than bridge restorations that have a higher chance of being replaced sooner.

But the prime reason is that some dental situations aren't suitable for dental implants. For instance, implants require a certain amount of bone for proper placement, so people with extensive bone loss may not be able to acquire them. Health conditions like uncontrolled diabetes or a compromised immune system can also complicate implant installation. A bridge in these cases may represent a better alternative.

With the help of your dentist, you'll need to consider your individual situation, dental and financial, in deciding between an implant or a bridge. And, if a dental bridge is your best option, it will be a solid choice for restoring your missing teeth and your smile.

AlthoughChallengingCleaningAroundImplantsBoostsTheirLongevity

Daily oral hygiene and regular dental cleanings help keep your natural teeth and gums healthy and disease-free. But they're also a priority with dental implants. Here's why.

Unlike other restorations, an implant replaces both a tooth's crown and root, the latter by way of a titanium metal post imbedded into the jawbone. Bone cells grow and adhere to the metal surface, forming a secure and lasting hold.

But although quite durable, this hold differs significantly from natural teeth, which are actually held in place by a tough, elastic tissue called the periodontal ligament. The attachment of the ligament's tiny fibers to both tooth and bone secure the tooth in place, as well as supply it and the surrounding gums with nutrients and defensive antibodies to fight infection.

Implants don't have this relationship with the periodontal ligament. The tissues around an implant are thus susceptible to an aggressive form of periodontal (gum) disease called peri-implantitis. This kind of gum infection can progress rapidly, leading eventually to bone loss and possible failure of the implant.

Daily brushing and flossing of both natural and implant-supported teeth lowers the risk of gum disease, particularly peri-implantitis. It's also imperative that you undergo regular cleanings, at least every six months, with your dentist or dental hygienist.

These, however, won't be the typical cleanings performed on natural teeth. Hygienists don't use metal cleaning implements to remove plaque and tartar deposits because they can scratch the metal materials of the implant and crown. These microscopic scratches can then attract bacteria that trigger gum infections. Instead, they'll use instruments made of plastics or resins.

Hygienists also rely heavily on ultrasonic equipment that vibrates plaque loose on or around implants, which are then flushed away with water. The tips used with these instruments are also typically made of nylon or plastic sheathing.

Even with the extra hygiene care needed, implants still enjoy a 95% or higher survival rate after ten years. You can ensure your implants achieve that level of durability by keeping them clean and seeing your dentist at the first sign of a gum infection.

DiabetesDoesntHavetoStopYouFromGettinganImplant-ifitsUnderControl

You would love to replace a troubled tooth with a dental implant. But you have one nagging concern: you also have diabetes. Could that keep you from getting an implant?

The answer, unfortunately, is yes, it might: the effect diabetes can have on the body could affect an implant's success and longevity. The key word, though, is might—it's not inevitable you'll encounter these obstacles with your implant.

Diabetes is a group of metabolic diseases that interfere with the normal levels of blood glucose, a natural sugar that is the energy source for the body's cells. Normally, the pancreas produces a hormone called insulin as needed to regulate glucose in the bloodstream. A diabetic, though either can't produce insulin or not enough, or the body doesn't respond to the insulin that is produced.

And while the condition can often be managed through diet, exercise, medication or supplemental insulin, there can still be complications like slow wound healing. High glucose can damage blood vessels, causing them to deliver less nutrients and antibodies to various parts of the body like the eyes, fingers and toes, or the kidneys. It can also affect the gums and their ability to heal.

Another possible complication from diabetes is with the body's inflammatory response. This is triggered whenever tissues in the body are diseased or injured, sealing them off from damaging the rest of the body. The response, however, can become chronic in diabetics, which could damage otherwise healthy tissues.

Both of these complications can disrupt the process for getting an implant. Like other surgical procedures, implantation disrupts the gum tissues. They will need to heal; likewise, the implant itself must integrate fully with the bone in which it's inserted. Both healing and bone integration might be impeded by slow wound healing and chronic inflammation.

Again, it might. In reality, as a number of studies comparing implant outcomes between diabetics and non-diabetics has shown, there is little difference in the success rate, provided the diabetes is under control. Diabetics with well-managed glucose can have success rates above 95%, well within the normal range.

An implant restoration is a decision you should make with your dentist. But if you're doing a good job managing your diabetes, your chances of a successful outcome are good.

IfAppropriateAntibioticsbeforeImplantSurgeryCouldReduceInfectionRisk

Millions of microorganisms call your mouth home—and while most are friendly, some are not. An invasive procedure like implant surgery can disrupt the mouth's soft tissues and allow disease-causing bacteria to enter the bloodstream.

This isn't necessarily a major concern if your immune system is sound—your body will move quickly to quash any developing infection. But if your body's defense is weak or compromised by other health conditions, an ensuing infection could cause you problems. In the case of a dental implant, a localized infection around it could lead to its failure.

The bone normally grows and adheres to the surface of an implant soon after it's placed, giving it the added strength and durability for which implants are best known. A bacterial infection, though, could impede bone integration and weaken the implant's hold within the jaw.

One way to avoid this is by treating patients at high risk for infection with an antibiotic before the procedure. In one recent study, researchers concluded that patients receiving a 2-gram dose of amoxicillin an hour before implant surgery helped reduce the risk of future implant failure.

But before taking this route, the dentist must first decide whether antibiotic pre-treatment might be more detrimental than beneficial to an individual patient. Antibiotics can cause side effects in certain people ranging from diarrhea to allergic reactions. Healthcare providers must also be prudent with administering antibiotics for the good of society in general—overuse can potentially give rise to antibiotic-resistant bacteria.

A number of healthcare associations highly recommend antibiotic pre-treatment for any dental patient with prosthetic heart valves, a history of infective endocarditis, a heart transplant and similar heart conditions. They also recognize patients with conditions like prosthetic joints, weakened immune systems, diabetics or other serious health problems could also benefit from antibiotic pre-treatment, but leave it to the physician's discretion on whether or not it's appropriate for an individual patient.

If you're planning to undergo implant surgery or a similar procedure and are concerned about infection, speak with your dentist about whether you would qualify and benefit from antibiotic pre-treatment. If appropriate, taking an antibiotic beforehand could minimize your infection risk.

SmokingCouldShortenYourImplantsLongevity

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.

But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.

There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.

The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.

During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.

If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.

And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.
