TheDigitalRevolutionIsTransformingImplantTherapy

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.

That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.

Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.

Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.

Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.

Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.

These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

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.

AnImplantRestorationCouldPreventBoneLoss

Losing teeth continues to be an all too common experience for people, especially those in their senior years. Fortunately, there are several ways to replace them, ranging from partial or full dentures to implants.

Some, though, postpone or simply choose not to replace a lost tooth, often because of the cost. But putting off a dental restoration could have a long-term impact on your health, and not in a good way. Continuing bone deterioration is one of the top consequences of delayed restoration.

Like other bones in the body, the jawbone is living tissue with cells that form, grow and eventually wear out. At the end of their life, these older cells give way to new cells. Eating and chewing play an important role in maintaining this growth cycle: the forces we generate as we chew travel up through the tooth roots to stimulate bone growth in the jaw.

When a tooth goes missing, though, the stimulus ends. Over time the bone cell replacement rate can fall off and the bone slowly loses volume. To make matters worse, bone loss can continue beyond the immediate bone underlying the tooth and affect the rest of the jawbone. The jaw can shrink in height and width, and in time become weaker overall and more susceptible to fracture.

But dental implant restorations in particular could help stop or even reverse bone deterioration at the site of the missing teeth. The titanium post implanted in the jaw attracts bone cells, which grow and adhere to its surface. Over time the bone fills in and becomes stronger.

You don't want to wait too long, though, because implants depend on a minimum amount of bone present for secure placement. You should therefore undergo an implant restoration as soon as it's practical after tooth loss. Otherwise, although we may be able to restore some of the lost bone with bone grafting, you may need to consider another restorative option.

When it comes to replacing missing teeth, time isn't on your side. But the right kind of dental restoration undertaken promptly can make for a brighter, healthier future.
