When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.
Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.
But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.
CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.
Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.
Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.
Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.

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.

So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.
Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).
Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.
Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.
That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.
Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.
To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.
While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.

If you're considering dental implants, they'll need to be surgically placed in the jaw bone. But don't be alarmed — it's a relatively minor procedure that usually requires nothing more than local anesthesia.
But that being said, it's still an invasive procedure that involves making incisions in gum and bone tissues. That could introduce bacteria into the bloodstream and pose, for certain individuals, a slightly greater risk of infection.
But infection risk is quite low for most healthy patients. As a result, implants enjoy a greater than 95-percent success rate ten years after installation. But some patients have health issues that increase their risk of infection. These include older adults with a weakened immune system, smokers, diabetics or those well under or over their ideal weight.
If you have these or similar health situations, we may recommend undergoing an antibiotic treatment before you undergo surgery. This can help prevent bacteria from spreading and reduce the likelihood of an infection.
Preventive antibiotic therapy is commonplace with many other dental procedures. Both the American Dental Association and the American Heart Association recommend antibiotics before any invasive oral procedure for patients with prosthetic (false) heart valves, past endocarditis, a heart transplant or other heart conditions. To lower the risk of implant failure due to infection, we often advise antibiotics for patients who fall in these categories, as well as those with similar conditions mentioned earlier.
Of course, whether pre-surgical antibiotics is a wise choice for you will depend on your medical history and current health status. We'll consider all these factors thoroughly before advising you. But if you are more susceptible to infection, antibiotics before surgery could potentially lower your risk for an implant failure.
You’ve probably heard a lot of great things about dental implants as a replacement for missing teeth. But there’s one aspect about implants that may cause you hesitation about choosing them: the cost. If you have multiple teeth to be replaced, the expense of implants may seem even further beyond your means.
But before you decide against what’s widely considered the premier tooth replacement option, it would be beneficial for you to look at their cost from a long-term perspective. You may find implants are actually a cost-effective investment in both your oral health and your smile.
So, what sets the dental implant apart from other options? One of its most important attributes is its life-like appearance. Not only does the visible crown resemble the color, shape and texture of natural teeth, the implant’s placement can so precisely mimic the appearance of natural teeth emerging from the gums, it’s indistinguishable from the real thing.
They’re not just attractive, but also durable. This is due in large part to titanium, the most common metal used in implants, which has the unique quality of being osseophilic, or “bone-loving.” Bone cells naturally attract to titanium and over time will grow and adhere to the implant in a process known as osseointegration. As a result, the implant’s attachment in the jaw becomes strong and secure.
This durability gives implants a greater longevity on average than most other replacement options. If you thus compare the total costs for an implant (including maintenance) over its projected life with the costs of other options like dentures or fixed bridges, you’ll find implants may actually cost less over time.
That may sound affordable for one or two missing teeth — but what about several? Replacing multiple teeth individually with implants can be quite high; but implants are also versatile — just a few strategically placed implants can support a fixed bridge or overdenture. This “hybrid” solution combines the affordability of these other options with the stability of implants.
Before weighing your options, you should first undergo a complete dental examination to see if you’re a candidate for implants. From there we can help you decide whether implants are the right investment for your health and your smile.
