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 the premier option for tooth replacement. While all implant procedures follow the same general concept — a titanium post surgically inserted into the jawbone with an attached life-like crown — the installation process can vary.
From their earliest history, implants have usually been installed through a two-stage process. In the first stage, the surgeon inserts the titanium post in the bone and leaves it “submerged” below the gum level to protect it from oral bacteria and the effects of chewing and biting. About three months later after the bone attaches to the titanium (a process called osseointegration), the surgeon then performs the second stage by re-exposing the implant and attaching a temporary abutment and crown for the patient to wear while the permanent abutment and crown are fabricated and later attached in 2-6 weeks.
In recent years, advancements in materials and design have made possible a one-stage process that allows the implant to protrude above the gum line during osseointegration and shortens the process. After the initial three-month healing period, the implant is ready for “loading” with the permanent crown.
The choice between which of these two procedures should be used for your implants will first depend on the type of tooth being replaced. A front tooth benefits from the one-stage procedure for cosmetic reasons because the surgeon can install a temporary crown to the exposed abutment during osseointegration (as long as the temporary tooth isn’t in functional contact with other teeth). An implant for a back tooth, on the other hand, doesn't have a large cosmetic demand so those one stage procedures usually end up with an exposed healing abutment but no temporary crown.
The strength of the bone is also a factor. Some bone tends to be softer, particularly in the back of the mouth. There’s a chance the implant could move in this softer bone, adversely affecting the outcome. For this reason, the two-stage procedure can be the preferred approach for posterior teeth as it offers more protection from movement.
You can be sure we’ll consider all these and other factors during your initial examination, and then advise you on the best approach. Above all, we want to make sure — whether a one-stage or a two-stage implant process — the result is a smile you can be proud of.

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.

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.

There are several reasons why dental implants are so popular. Perhaps the most important, though, is their longevity: if maintained properly implants can last for decades. However, they’re not indestructible—certain mouth conditions could put them at risk for early failure. But if you address emerging problems early, you may be able to prevent that unfortunate outcome.
Your implants may be in danger, for example, if you have a teeth grinding or clenching habit. This occurs when a person involuntarily and repeatedly bites down on their teeth when not chewing or speaking. Usually triggered in adults by high stress, teeth grinding can subject both natural teeth and implants to damaging levels of force. Over time this can cause bone loss around an implant and weaken their support. It could also cause a direct break in an implant.
But there are ways to stop or at least reduce the effects of teeth grinding. One effective way is a custom-made bite guard you wear while you sleep. Made of hard plastic, the guard prevents the teeth from making solid contact with each other, reducing the amount of force generated.
A more prominent problem is periodontal (gum) disease, a bacterial infection caused by built-up dental plaque on tooth surfaces. This can trigger inflammation, a normal defensive response that when it persists for an extended period of time can damage tissues and supporting bone. It can also cause a specific form of gum disease related to implants called peri-implantitis, in which the tissues that support an implant become infected and weaken, leading eventually to possible implant failure.
If you have implants, then, you should brush and floss daily to prevent gum disease, as well as see your dentist at least every six months for cleanings and checkups. And if you notice anything like reddened, swollen or bleeding gums, see your dentist immediately. The sooner you undergo treatment, the better the outcome for your implants as well as your overall health.
Dental implants can give you years of great service and can prove to be well worth the cost. But you’ll have to stay on your guard against gum disease and other mouth conditions that could endanger them down the road.
