Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
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.

What's so special about dental implants — and why should you consider one to replace a missing tooth?
Although they've only been widely available for thirty years, dental implants have climbed to the top of tooth replacement choices as the premier restorative option. Since their debut in the 1980s, dentists have placed over 3 million implants.
There's one overriding reason for this popularity: in structure and form, dental implants are the closest replacement we have to a natural tooth. In fact, more than anything else an implant is a root replacement, the part of the tooth you don't see.
The artificial root is a titanium post surgically imbedded into the jaw bone. Later we can attach a porcelain crown to it that looks just like a visible tooth. This breakthrough design enables implants to handle the normal biting forces generated in the mouth for many years.
There's also an advantage in using titanium dental implants. Because bone cells have a special affinity to the metal, they will grow and attach to the implant over time. Not only does this strengthen the implant's hold within the jaw, the added growth also helps deter bone loss, a common problem with missing teeth.
It's this blend of strength and durability that gives implants the highest success rate for any tooth replacement option. Over 95% of implants placed attain the 10-year mark, and most will last for decades.
Dental implant treatment, however, may not be possible in every situation, particularly where significant bone loss has occurred. They're also relatively expensive, although more cost-effective than other options over the long term.
Even so, implants can play an effective and varied role in a dental restoration. While single implants with attached crowns are the most common type of replacement, they can also play a supporting role with other restorative options. As few as two strategically placed implants can provide a more secure connection for removable dentures or fixed bridges.
You'll need to first undergo a thorough dental examination to see if implants could work for you. From there, we'll be happy to discuss your options for using this "best of the best" restoration to achieve a new, beautiful smile.
