DentalImplantsCouldHelpPreserveBoneAfterToothLoss

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.

Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.

But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.

As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.

Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.

Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.

This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.

If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

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.

DentalImplantsAreEvenMoreAdvancedThanksToTheseOtherTechnologies

When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.

Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.

But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.

CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.

Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.

Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.

Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.

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.

CelebratingPaulReverePatriotandDentalCraftsman

While celebrating all that a new year brings, take a moment to remember the New Year's Day birthday of a true American patriot: the legendary Paul Revere. Ironically, he became a legend some 80 years after his midnight trek to warn colonists of approaching British troops, thanks to Henry Wadsworth Longfellow's 1861 poem “Paul Revere's Ride.” He was much better known to his fellow Bostonians as a prosperous silversmith, engraver—and “artificial teeth” maker.

That's right. Among his many business endeavors, Revere's résumé also included dental prosthetics, specifically custom dentures made of ivory. For the time, his work was state-of-the-art technology that far surpassed older tooth replacement methods.

But when we compare Revere's foray into the dental arts and today's restorations, his high quality 18th Century dentures were the proverbial “horse and buggy,” while modern denture technology seems like “supersonic transport.” Not only are today's dentures made of superior materials that are more “toothlike” in appearance, the means to create them using digital technology gives wearers a more secure and comfortable fit.

The modern denture—an appliance that replaces multiple or all lost teeth—is composed of a polymer base, usually acrylic that is colored to resemble gum tissue. Attached to this base are the prosthetic (“false”) teeth that replace those lost along the jaw. These new teeth are usually made of a durable dental material like porcelain that looks and functions like real teeth.

The basic design of today's denture hasn't changed much in the last century. What has changed is our ability to create dentures that follow an individual jaw contours much more precisely. Using the latest digital technology, we're able to obtain highly accurate impressions of the mouth to guide the manufacturing process. Fit is critically important for how dentures feel and function in the mouth. If they are too loose, they become uncomfortable and limit which foods you can eat.

If that weren't enough, recent advancements with dental implants have taken dentures to an entirely new level, beyond anything imaginable in Revere's day. We're now able to create dentures that connect or are permanently affixed to implants set within the jaw, which makes them more stable and secure. An implant-supported denture also helps prevent bone loss, a weakness of traditional dentures, causing them to loosen over time.

As amazing as they are, we wouldn't have the modern version of dentures without craftsmen like Paul Revere who helped advance the cause of dental restoration. So, lift a glass of holiday cheer this season to this hero of the American Revolution—and of American dentistry.
