Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

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.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.

We've been using bridges to replace missing teeth for decades. Now, recently-developed implant-supported bridges are even more dependable, promising greater durability and less interference with remaining natural teeth.
But just like other restorations, you'll need to keep implant bridges clean to ensure their longevity. Although both the bridge and implants are impervious to disease, the supporting gums and bone aren't. If they become infected, they can break down and your restoration will fail.
Cleaning an implant-supported bridge includes flossing around each of the implants to remove dental plaque, a thin film of food particles and bacteria most responsible for dental disease. To perform this task, you'll have to pass the floss between the bridge and gums to access the sides of each implant.
To help make it easier, you can use a tool like a floss threader, a thin, shaft-like device with a loop on one end and a needle-like point on the other. You'll first thread about 18" of floss through the end and then pass the threader between the bridge and gums with the sharp end toward the tongue.
With the threader completely through, you'll then wrap the floss around your fingers as with regular flossing and move the floss up and down each side of the implants you can access. You'll then pull the floss out, reload the threader and move to the next section, repeating this process until you've flossed each side of each implant.
You can also use pre-cut floss with a stiffened end to thread between the bridge and gums or an interproximal brush with a thin bristled head that can reach underneath the bridge. And you might consider using an oral irrigator, a pump device that sprays a stream of pressurized water to remove and flush away plaque around implants.
To round out your hygiene efforts, be sure you visit your dentist at least twice a year for dental cleanings. Your dentist can also advise you and give you training on keeping your implants clear of disease-causing plaque. Cleaning around your implants will help ensure your restoration will last.

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.
