CouldYourMetalAllergyKeepYouFromObtainingDentalImplants

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.

But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?

The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.

An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).

A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.

Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.

While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.

Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.

CleaningAroundImplantsCrucialtoProtectingThemfromLoss

Unlike the natural tooth it replaces, a dental implant is impervious to decay. But don’t think that means you can relax your oral hygiene habits — even though the implant itself can’t be infected, the surrounding gum tissues and bone can. And if they’re not properly cared for you might eventually lose the implant.

In fact, implants may be more susceptible to problems from impacted food that becomes wedged between the gums and teeth than their natural counterparts. Natural teeth are connected to the jaw by way of a resilient, elastic tissue known as the periodontal ligament: the ligament resides in the space between the tooth root and the bone and attaches to both through tiny fibers. The bone and ligament are protected by an attachment of gum tissue that covers all of the surrounding bone and attaches to the root surface. The outer gum tissue surface is covered by a protein called keratin that makes it resistant to wear.

On the other hand, these periodontal ligament fibers don’t exist when implants are present as the implant is fastened directly to the bone. Because it doesn’t have this ligament attachment, and the gum tissues around can’t attach to the implant as with natural teeth, it may be more vulnerable to bacteria or trauma caused by food impaction. So, cleaning and caring for dental implants is just as important, if not more so than with natural teeth.

If the gums around an implant become infected and inflamed it could lead to peri-implantitis, a condition that can destroy the bone attachment between the implant and the bone. In other words, the loss of bone support can weaken the integration of the implant with the bone. As more and more attachment is lost, the implant can loosen and eventually be lost.

The best way to avoid this is with consistent daily hygiene and regular dental checkups. And, if you notice any signs of swelling or redness of the gums around an implant, contact us as soon as possible. The sooner we begin treatment to alleviate the infection, the less danger there will be of losing your implant.

YourHealthCouldAffecttheLongevityofaDentalImplant

There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.

But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.

For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.

We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.

Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.

Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.

The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.

WhattoExpectBeforeDuringandAfterImplantSurgery

People are choosing dental implants at an increasing rate to replace missing teeth, either as an individual tooth or as a support for other restorations. But unlike other replacement options, we must surgically install the titanium post at the heart of the system directly into the jawbone.

While the term “surgery” might make you nervous, there's nothing at all to worry about. Here's what you need to know about before, during and after this relatively minor procedure.

Before. While the actual procedure is no more complicated than a tooth extraction, it ultimately depends on careful planning beforehand. Using x-ray diagnostics, we prepare a precise surgical guide to help us locate the best position to place them for a successful outcome. We'll also need to check bone volume to make sure there's an adequate amount to securely anchor the implant. If the bone is insufficient you may need bone grafting to build up the site or another replacement option.

During. The actual procedure begins, of course, with local anesthesia to numb the site — you should feel no pain and very minimal discomfort. We access the bone through the gums; often using a surgical guide for alignment, we create a small channel or hole with a sequence of drills that gradually increase the size until it can accommodate the implant. We remove the implants from their sterile packaging and install them immediately into the channel. After confirming their proper positioning with x-rays, we can close the gum tissues over it for protection during healing or attach a healing abutment that extends through the gum tissue thereby avoiding a second surgical procedure.

After. Because we disrupt relatively little of the soft tissue and bone, there's only minimal discomfort afterward easily managed with aspirin, ibuprofen or similar anti-inflammatory medication. We may also prescribe antibiotics to guard against infection while the gums heal. During the next several weeks, the titanium post, which has an affinity to bone, will become more secure as bone cells grow and adhere to it. It's also during this time that a dental lab creates your permanent crown or other restoration that matches the color and tooth shape so it will blend with your other teeth.

This process is complete when we install the final restoration onto the implant. You'll have a new smile and better function.

YourNewImplantsNeedProperHygieneJustasMuchasyourOtherTeeth

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.
