GumDiseaseisStillaThreattoYourDentalImplants

You’ve invested quite a bit in your new dental implants. And it truly is an investment: because of implants’ potential longevity, their long-term costs could actually be lower than other restorations whose upfront costs might be less.

But to better ensure their longevity, you’ll need to keep your implants and the natural tissues supporting them clean of bacterial plaque, a sticky biofilm that can cause periodontal (gum) disease. Although the implant itself is unaffected by disease, the natural tissues around it can be.  An infection could ultimately weaken the bone supporting the implant and lead to its failure.

Such an infection involving implants could advance rapidly because they don’t have the natural defenses of the original teeth. Our natural teeth are connected to the jaw through the periodontal ligament, a collagen network that attaches to both the teeth and the bone through tiny tissue fibers. This connection also provides access to antibodies produced by the body to fight infection.

By contrast, we place implants directly into the jawbone. While this creates a very secure attachment, the implant won’t have the same connection as teeth with the body’s immune system. That means any infection that develops in surrounding tissues can spread much more rapidly—and so must be dealt with promptly.

Treating this particular form of gum disease (known as peri-implantitis) is similar to infections with natural teeth and gums, with one important difference involving the tools we use to remove plaque from them. While natural teeth can handle metal scalers and curettes, these can create microscopic scratches in the porcelain and metal surfaces of an implant and create havens for further bacterial growth. Instead, we use instruments made of plastic or resin that won’t scratch, as well as ultrasonic equipment to vibrate plaque loose.

To avoid an infection, it’s important that you brush your implants and surrounding tissues just like you would your natural teeth (be sure you use a soft-bristled brush). And keep up regular dental visits for thorough cleanings and checkups to stay ahead of any developing gum infection. Maintaining your dentures will help ensure they continue to brighten your smile for a long time.

NotEnoughBoneSupportforanImplantHeresaWaytoRebuildIt

Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.

If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.

The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.

But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.

But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.

If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.

So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.

Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).

Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.

Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.

That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.

Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.

To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.

While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.

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.

KeepingupGoodHygieneStillaNecessitywithDentalImplants

Dental implants are widely considered the most durable tooth replacement option, thanks in part to how they attach to the jaw. But durable doesn't mean indestructible — you must take care of them.

Implants have a unique relationship to the jawbone compared to other restorations. We imbed a slender titanium post into the bone as a substitute for a natural tooth root. Because bone has a special affinity with the metal, it grows to and adheres to the implant to create a secure anchor. This unique attachment gives implants quite an advantage over other restorations.

It isn't superior, however, to the natural attachment of real teeth, especially in one respect: it can't match a natural attachment's infection-fighting ability. A connective tissue attachment made up of collagen fibers are attached to the tooth root protecting the underlying bone. An elastic gum tissue called the periodontal ligament lies between the tooth root and the bone and attaches to both with tiny collagen fibers. These attachments create a network of blood vessels that supply nutrients and infection-fighting agents to the bone and surrounding gum tissue.

Implants don't have this connective tissue or ligament attachment or its benefits. Of course, the implants are made of inorganic material that can't be damaged by bacterial infection. However, the gums and bone that surround them are: and because these natural tissues don't have these same biologic barriers to infection and perhaps access to the same degree of antibodies as those around natural teeth, an infection known as peri-implantitis specific to implants can develop and progress.

It's therefore just as important for you to continue brushing and flossing to remove bacterial plaque that causes infection to protect the gums and bone around your implants. You should also keep up regular office cleanings and checkups. In fact, we take special care with implants when cleaning them by using instruments that won't scratch their highly polished surfaces. Such a scratch, even a microscopic one, could attract and harbor bacteria.

There's no doubt dental implants are an excellent long-term solution for restoring your smile and mouth function. You can help extend that longevity by caring for them just as if they're your natural teeth.
