YouCanHaveaSuccessfulImplantOutcomeifYourDiabetesisUnderControl

Around one in ten U.S. adults have diabetes, a metabolic disease that can disrupt other aspects of a person's health like wound healing and vision. It could also cause complications with dental implants, the premier replacement choice for missing teeth.

There are two basic types of diabetes. In type 1 diabetes, the pancreas stops producing insulin, a hormone needed to regulate the amount of sugar glucose in the bloodstream. With the more prevalent type 2 diabetes, the body either doesn't produce enough insulin or doesn't respond efficiently to the insulin produced.

Uncontrolled diabetes can contribute to several dangerous health conditions. In addition to vision impairment and poor wound healing, diabetics are at higher risk for other problems like kidney disease or nerve damage. Drastic swings in blood glucose levels can also cause coma or death.

Many diabetics, though, are able to manage their condition through diet, exercise, medications and regular medical care. Even so, they may still encounter problems with wound healing, which could complicate getting a dental implant.

An implant is composed of a titanium metal post imbedded into the jawbone. Because of its affinity with titanium, bone cells naturally grow and adhere to the implant's metal surface. Several weeks after implant surgery, enough bone growth occurs to fully secure the implant within the jaw.

But this integration process may be slower for diabetics because of sluggish wound healing. It's possible for integration to not fully occur in diabetic patients after implant surgery, increasing the risk of eventually losing the implant.

Fortunately, though, evidence indicates this not to be as great a concern as once thought. A number of recent group studies comparing diabetic and non-diabetic implant patients found little difference in outcomes—both groups had similar success rates (more than 95 percent).

The only exception, though, were diabetic patients with poor glucose control, who had much slower bone integration that posed a threat to a successful implant outcome. If you're in this situation, it's better if you're first able to better control your blood glucose levels before you undergo surgery.

So, while diabetes is something to factor into your implant decision, your chances remain good for a successful outcome. Just be sure you're doing everything you can to effectively manage your diabetes.

ImplantsCouldHelpYouKeepRemainingTeethLonger

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.

This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.

Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.

Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.

Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.

In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.

More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

TheRealTruthBehindEdHelmsMissingToothinTheHangover

Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.

In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.

Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.

Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.

If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.

The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.

Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.

AlthoughRareAllergicReactionstotheMetalinImplantsCouldbeaConcern

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.

An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.

A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.

There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.

Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.

Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

If you would like more information on the effects of metal allergies on dental implants, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Metal Allergies to Dental Implants.”

3CuttingEdgeWaysYouCouldBenefitfromDentalImplants

Since their introduction over thirty years ago, dental implants have become the most popular choice for dental restoration. Their large variety of shapes and sizes — a far cry from the limited choices of the 1980s — has only served to increase their popularity.

In recent years there's also been an expansion in their applicability. Most people recognize them as replacements for individual teeth — but they can do much more. They're now playing a pivotal role in other dental restorations or situations.

Here are 3 of those “cutting edge” ways implants could change your dental health and smile for the better.

Fixed bridgework. In a traditional bridge, prosthetic (false) teeth use the natural teeth on either side of the empty space for support. In this updated version, implants become the support base for the bridge. For example, a bridge as small as three crowns can be supported by two implants attached to the outside crowns of the bridge. Four to eight implants can support a bridge as large as an entire arch of teeth.

Over-dentures. In cases of significant bone loss, a full or partial denture may be a better option than a fixed bridge. Traditional dentures, though, can contribute to even more bone loss, which can cause the dentures to eventually lose their fit. Implants not only can help stop further bone loss but can also stimulate increased bone density. Two or more standard or mini-sized-sized implants can support a full or partial denture.

Orthodontics anchorage. People with missing teeth aren't the only ones who can benefit from implants. While most bite repairs only require the back teeth to provide anchorage for braces, certain complex bites may need a different point of anchorage. Orthodontists can create a more feasible anchorage point with an implant or a temporary anchorage device (TAD) imbedded in the jaw. This can help isolate teeth that need to be moved from those on the arch that don't.
