ImplantSurgeryASafeandRoutineProcedure

Unlike other tooth replacement options, dental implants require a surgical procedure. But don't let your imagination run wild — the procedure is relatively minor and easy for most people to undergo.

Implants are unique among restorations because they replace a tooth's root. A metal titanium post, substituting for the root, must be surgically placed into the jawbone. While the procedure itself is simple and no more involved than a tooth extraction, it does require careful attention to detail before, during and afterward.

Our first step is to examine the target site with x-rays (often CT scanning) to pinpoint the best location for placement. This is critical because where we place the implant will have a huge bearing on how attractive and natural the implant finally appears. From this evaluation we frequently create a surgical guide.

Surgery begins with a local anesthesia to completely numb the site. You will feel no pain during the procedure and only minimal discomfort for a few days afterward. We then make small incisions in the gums to access the bone and create a small channel or hole.

Using the surgical guide, we then initiate a drilling sequence that gradually increases the size of the channel until it's the size and shape of the implant post. One thing we must do at this point is take our time: we use gentle pressure and water-cooling to avoid overheating and damaging the bone.

Once we're finished with drilling we remove the implant from its sterile packaging and imbed it directly into the prepared channel. It's then a matter of verifying the location with x-rays and then closing the gum tissue with self-absorbing sutures if necessary.

Most patients only need mild pain medication like aspirin or ibuprofen to manage discomfort afterwards. You won't even notice it in a week or less. After several weeks in which the bone grows and adheres to the implant (a process called osseointegration), you'll be ready for the final step, attaching the life-like porcelain crown to the implant.

Although the process can take several weeks to months, your discomfort should be minimal at any stage. In the end, your patience will be rewarded with a new, more attractive smile.

AvoidImplantFailurebyWatchingOutforTheseMouthProblems

There are several reasons why dental implants are so popular. Perhaps the most important, though, is their longevity: if maintained properly implants can last for decades. However, they’re not indestructible—certain mouth conditions could put them at risk for early failure. But if you address emerging problems early, you may be able to prevent that unfortunate outcome.

Your implants may be in danger, for example, if you have a teeth grinding or clenching habit. This occurs when a person involuntarily and repeatedly bites down on their teeth when not chewing or speaking. Usually triggered in adults by high stress, teeth grinding can subject both natural teeth and implants to damaging levels of force. Over time this can cause bone loss around an implant and weaken their support. It could also cause a direct break in an implant.

But there are ways to stop or at least reduce the effects of teeth grinding. One effective way is a custom-made bite guard you wear while you sleep. Made of hard plastic, the guard prevents the teeth from making solid contact with each other, reducing the amount of force generated.

A more prominent problem is periodontal (gum) disease, a bacterial infection caused by built-up dental plaque on tooth surfaces. This can trigger inflammation, a normal defensive response that when it persists for an extended period of time can damage tissues and supporting bone. It can also cause a specific form of gum disease related to implants called peri-implantitis, in which the tissues that support an implant become infected and weaken, leading eventually to possible implant failure.

If you have implants, then, you should brush and floss daily to prevent gum disease, as well as see your dentist at least every six months for cleanings and checkups. And if you notice anything like reddened, swollen or bleeding gums, see your dentist immediately. The sooner you undergo treatment, the better the outcome for your implants as well as your overall health.

Dental implants can give you years of great service and can prove to be well worth the cost. But you’ll have to stay on your guard against gum disease and other mouth conditions that could endanger them down the road.

KeepanEyeontheJawBoneAfteraTeenagersToothLoss

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.

Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.

There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.

Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.

Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.

Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.

Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.

WhySmokingandDentalImplantsDontMix

With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.

But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.

The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.

The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.

Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.

So, what should you do if you’re a smoker and wish to consider implants?

First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.

It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.

CouldaMetalAllergyKeepYouFromGettingaDentalImplant

The dental implant is the closest thing in modern dentistry to a natural tooth. This is because an implant replaces more than the visible crown — it also replaces the root, thanks to a metal post imbedded in the bone.

But what if you have a metal allergy — are you out of luck replacing a tooth with an implant? Before answering this question, let's take a closer look at metal allergies.

An allergy is an overreaction of the body's immune system to a particular foreign substance. This response can be as inconsequential as a minor rash or as life-threatening as a shutdown of the body's organ systems. You can be allergic to anything, including metals.

Usually, these allergies are to specific kinds of metals. For example, about 17% of women and 3% of men are allergic to nickel, while smaller percentages are allergic to cobalt or chromium. Most allergic reactions to metal occur from external contact with jewelry or similar metal items that create rashes or other anomalies on the skin. On a more serious note, an allergy to metal in a body replacement part could result in the body rejecting it.

Metals have also played an important role in dental care, particularly dental amalgam used for tooth fillings. Dental amalgam is a mixture of a precious metal like gold or silver with other metals like copper, tin and, in small amounts, mercury. While dental amalgam has been used safely for decades, there have been rare cases of inflammation or rashes.

This brings us to dental implants and the most common metal used in them, titanium. The commercial version of this metal is highly prized in medical and dental applications because it has a special affinity with bone. Bone cells readily grow and adhere to the metal, which strengthens the bond between the implant and the jawbone.

Even if you have a rare allergy to certain metals, it's even rarer that would include titanium. In one particular study of 1,500 implant patients less than 1% reported any reaction at all.

If you're concerned, you can undergo testing to see if you react to titanium. More than likely, though, you'll be able to join the millions of other patients who have successfully restored their smiles with dental implants.
