While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Losing teeth to tooth decay or periodontal (gum) disease is never easy. But with implant-supported bridgework, you can regain lost function and appearance with a restoration that could last for many years.
Don’t think, though, that dental disease woes are a thing of the past with your new implants. Although your restoration itself can’t be infected, the supporting gums and underlying bone can, often through bacterial plaque accumulating around the implants. The bone that supports the implants could deteriorate, dramatically increasing your chances of losing your restoration.
It’s essential, then, that you keep the area between the bridge and gums clean of plaque through daily hygiene. This definitely includes flossing around the implants.
Flossing with an implant-supported bridge will be different than with natural teeth: instead of flossing between teeth you’ll need to thread the floss between the bridge and gums. Although this is a bit more difficult, it can be done with the help of a floss threader, a device with a loop on one end and a long, thin plastic point on the other—similar to a sewing needle.
To use it, thread about 18” of floss through the loop and then pass the threader’s thin end first through the space between the bridge and gums toward the tongue until the floss threader pulls through. You can then take hold of one end of the floss and then pull the threader completely out from beneath the bridge. Then, you wrap the ends around your fingers as you would normally and thoroughly floss the implant surfaces you’re accessing. You then release one end of the floss, pull out the remainder, rethread it in the threader and repeat the process in the next space between implants.
You also have other hygiene tool options: prefabricated floss with stiffened ends that thread through the bridge-gum space that you can use very easily; or you can purchase an interproximal brush that resembles a pipe cleaner with thin plastic bristles to access the space and brush around the implants.
Some patients also find an oral irrigator, a handheld device that sprays a pressurized stream of water to loosen and flush away plaque, to be an effective way of keeping this important area clean. But that said, oral irrigators generally aren’t as effective removing dental plaque as are floss or interproximal brushes.
Whatever flossing method you choose, the important thing is to choose one and practice it every day. By keeping bacterial plaque from building up around your implants, you’ll help ensure you won’t lose your restoration to disease, so it can continue to serve you for many years to come.
Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.

Since their introduction over three decades ago, dental implants have evolved into dentistry’s premier tooth replacement choice. While their primary purpose is to replace missing teeth and rejuvenate a patient’s smile, they’re also regarded for another important benefit: they can slow or stop bone loss accelerated by the loss of teeth.
Like all living tissue, bone has a life cycle. Older bone dissolves and is absorbed by the body, a process called resorption. New bone forms and grows to replace the resorbed bone in response to stimuli occurring within the body. In the jaw, this stimulation comes from the forces the teeth receive when we bite or chew.
When a tooth is lost, however, it no longer transmits these force stimuli to the adjacent bone. This results over time in less new growth to replace resorbed bone, and the overall bone mass shrinks. In fact, about a quarter of the normal bone width will diminish in the first year alone after tooth loss. Other serious problems follow, like gum recession or chewing and speaking difficulties. A person’s appearance may also suffer, because as resorption continues unchecked, the underlying foundational bone will continue to shrink. As more teeth are lost, a decrease in the distance between the nose and chin may result causing the lower third of the face to become smaller in size.
Dental implants can interrupt this process by encouraging bone growth around the implant. Implants are made of “osseophilic” titanium, meaning the metal has a natural affinity with bone. After implantation, bone cells will begin to grow and attach to the titanium post. The enhanced growth stabilizes bone loss by providing stimulation to the bone as teeth once did, thereby maintaining bone levels and minimizing potential effects on the patient’s appearance.
Ironically, too much bone loss could make the installation of implants more difficult, since they require a minimum level of bone mass for anchorage. Receiving an implant as soon as is practical once a tooth is lost will minimize the chances of that occurring — and a better chance of improving bone health overall.

Many people with diabetes are hesitant about getting dental implants because they’re under the impression their chances of failure are greater than for non-diabetics. But if you’re one of the 26 million Americans with diabetes, that isn’t necessarily so — with a little extra precaution before, during and after implant surgery.
Diabetes is a group of diseases that affect how the body processes glucose. This simple sugar is used by the body to provide energy to cells, but can also cause damage if its volume level in the bloodstream is too high. The body normally regulates this through the hormone insulin produced by the pancreas.
The pancreas in people with Type 1 diabetes doesn’t produce insulin and so they must receive an outside source of the hormone through daily injections with careful daily monitoring of glucose levels. Those with Type 2 diabetes, the most common form of the disease, don’t produce a sufficient amount of insulin or the body no longer responds to the insulin produced. For either type, abnormal glucose levels — either too high or too low — can have adverse affects on the body, including blindness, nerve damage, gangrene, coma or death.
Diabetes can also slow wound healing, increase the risk of infection, and alter the body’s inflammatory response, all of which are major concerns when placing implants. Because implant placement involves minor surgery in which a wound results, there’s been wide concern that a slower healing process could increase the risk of implant failure.
Recent studies, though, are encouraging especially for patients who have their diabetes under control through medication, diet and exercise. Patients with poor glucose control are at higher risk, because it can take longer for the bone to heal around an implant after placement. For such individuals special considerations to guard against infection may be needed during implant surgery.
In fact, the implant success rate for most diabetics is about the same as for non-diabetic patients, 95%. With proper disease management and a little extra wound care, you can be among the many that experience a favorable outcome and a more attractive smile with dental implants.
