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.

Implant-BasedRemovableDenturesaGoodChoiceforPatientswithExtensiveBoneLoss

People who’ve lost all their teeth (a condition known as edentulism) face a decision on how to restore their lost function and appearance. And there are a number of options to consider.

A fixed bridge supported by dental implants, for example, is a good choice for patients who still have sufficient bone structure in their jaw. It’s not a good choice, however, for those with the opposite situation — who’ve experienced significant bone loss which has also affected their facial structure. For them, there’s a better alternative that also uses implants for support — the overdenture.

An overdenture is similar to a traditional denture, in that it’s made of life-like crowns permanently set in denture plastic, and may either partially or fully cover the roof of the mouth. The main difference, though, is that unlike traditional dentures which rest for support on the gum ridges, an overdenture is supported by strategically placed implants that the denture fits over and connects to — hence the name “overdenture.”

There are a number of advantages for an overdenture, especially for patients with bone loss. A removable, implant-supported denture can be designed to replace lost tissues that have altered facial appearance — to “fill in” the face and restore aesthetic harmony. Patients who’ve previously worn dentures will also often find their speech better improved than with fixed bridgework.

Because it’s removable, an overdenture and the underlying gums are easier to clean, which helps inhibit disease and lessen further bone loss. It also allows you to properly care for the denture, which can extend its longevity and reduce future potential maintenance and replacement costs.

If you would like to consider removable overdentures as an option, you should begin first with a thorough oral exam that includes evaluating the status of your bone, jaw and facial structure. From there we can advise you if overdentures are the best choice for you.

Implant-SupportedDenturesCouldImproveYourBoneHealth

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.

Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.

While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.

But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.

Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.

There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.

The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.

While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

QuizTestYourKnowledgeonDentures

Since as many as 26 percent of older U.S. adults have lost all their teeth, there are a large number Americans who wear full removable dentures, also known as false teeth. You may be one of them.

How much do you know about dentures? See if you can answer the following questions connected with lost teeth and dentures.

  1. Which word refers to the loss of all permanent teeth?
    1. Atrophy

AvoidThese4HealthProblemswithOneSimpleDenturePractice

Dentures can be an effective and affordable solution for people who've lost all their teeth. With them a person can once again eat nutritiously, speak clearly and smile confidently — and with regular care they can last for years.

As part of that ongoing care, be sure you consider one important thing with your dentures: you may want to take them out at night while you sleep. If you do you'll lessen your chances of developing these 4 health problems.

Accelerated bone loss. Traditional dentures are fitted to rest securely on the gums. This, however, creates pressure on the gums and the bony ridges beneath them that can contribute to bone loss. Wearing dentures around the clock usually accelerates this process, which could eventually lead to among other problems looser denture fit and discomfort.

Bacterial and fungal growth. Microorganisms that cause oral diseases find conducive breeding spots on the underside of dentures while they're worn in the mouth. Studies have found that people who continuously wear their dentures are more likely to have bacterial plaque and oral yeast than those that don't.

Potentially dangerous infections. Bacterial and fungal growth increases your risk of oral infections that could affect more than your mouth. A recent study of elderly nursing home residents found those who wore their dentures during sleep were over twice as likely to develop serious cases of pneumonia requiring hospitalization. It's believed bacteria harbored on the dentures can pass from the mouth to the lungs as a person breathes over them while they sleep.

Blocked salivary flow. During the night our salivary flow naturally ebbs; wearing dentures while we sleep could cause denture stomatitis, in which the tissues covered by a denture (particularly along the roof of the mouth) become inflamed and infected with yeast. It's often accompanied by angular cheilitis or cracking at the corners of the mouth that becomes infected by the same yeast.

Wearing your dentures while you sleep contributes to conditions ranging from irritating to life-threatening. To prevent such problems clean your dentures as well as the rest of your mouth regularly — and talk to your dentist whether you should leave them out when you go to bed.
