Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.
That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.
That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.
When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.
If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.
Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.
To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.

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.

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.
