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.

If you're considering dental implants to replace one or more missing teeth, you'll need to undergo a minor to moderate surgical procedure (depending on the number of implants) to install them. Depending on your current health status and medical history, you may need antibiotics before or after the procedure to help ensure a successful outcome.
Although implants have a high success rate (over 95%), they can still fail — and bacterial infection is a major culprit. Installing implants requires surgically accessing the bone through the gum tissues; you may also need other invasive procedures like tooth extraction or bone or gum tissue grafting. These disruptions to the soft tissues can introduce bacteria into the bloodstream.
In certain individuals, this can increase infection risk not only around the implant but also in other parts of the body. You may be at higher risk, for example, if you have serious health problems like cardiovascular disease or diabetes, a weakened immune system, you use tobacco or you're over or under normal weight. The American Dental and American Heart Associations both recommend antibiotics before dental implant surgery as a preventive measure against infection if you have a prosthetic heart valve, a history of infective endocarditis, a heart transplant or some congenital heart conditions.
For other patients with low to moderate risk for infection, there's vigorous debate on administering antibiotics before implant surgery. There are some side effects to antibiotic use, ranging from diarrhea to allergic reactions, and an increased concern in general to the developing resistance of many infectious agents due to the prevalent use of antibiotics. Many dentists and physicians are becoming more discriminate in the patients for which they prescribe antibiotics before surgical procedures.
It really comes down, then, to your particular case: not only the specific procedures you need but also your general health. After weighing these factors against the possible benefits for protecting your health and improving your odds of a successful outcome, we'll recommend whether antibiotic treatment for implants is right for you.
If you’ve just received a dental implant restoration, congratulations! This proven smile-changer is not only life-like, it’s also durable: more than 95% of implants survive at least 10 years. But beware: periodontal (gum) disease could derail that longevity.
Gum disease is triggered by dental plaque, a thin film of bacteria and food particles that builds up on teeth. Left untreated the infection weakens gum attachment to teeth and causes supporting bone loss, eventually leading to possible tooth loss. Something similar holds true for an implant: although the implant itself can’t be affected by disease, the gums and bone that support it can. And just as a tooth can be lost, so can an implant.
Gum disease affecting an implant is called peri-implantitis (“peri”–around; implant “itis”–inflammation). Usually beginning with the surface tissues, the infection can advance (quite rapidly) below the gum line to eventually weaken the bone in which the implant has become integrated (a process known as osseointegration). As the bone deteriorates, the implant loses the secure hold created through osseointegration and may eventually give way.
As in other cases of gum disease, the sooner we detect peri-implantitis the better our chances of preserving the implant. That’s why at the first signs of a gum infection—swollen, reddened or bleeding gums—you should contact us at once for an appointment.
If you indeed have peri-implantitis, we’ll manually identify and remove all plaque and calculus (tartar) fueling the infection, which might also require surgical access to deeper plaque deposits. We may also need to decontaminate microscopic ridges found on the implant surface. These are typically added by the implant manufacturer to boost osseointegration, but in the face of a gum infection they can become havens for disease-causing bacteria to grow and hide.
Of course, the best way to treat peri-implantitis is to attempt to prevent it through daily brushing and flossing, and at least twice a year (or more, if we recommend it) dental visits for thorough cleanings and checkups. Keeping its supporting tissues disease-free will boost your implant’s chances for a long and useful life.

You've seen the ads for obtaining a new tooth in one day with a dental implant. Those aren't exaggerated claims — you can leave the dental office the same day with a new tooth that looks and functions like the old one.
But the dramatic marketing aside, there is a bit more to the story. Same day tooth replacement isn't appropriate in every situation. And even when it is, there are risks for failure.
We can minimize those risks, however, by focusing on certain goals during the three distinct phases in the process: removing the natural tooth; placing the metal implant into the jawbone; and affixing the visible, crown.
It's crucial during tooth extraction that we avoid damaging the socket bone that will ultimately support the implant's titanium post. If the socket walls break down it could set up future gum recession or cause us to abort the implant procedure altogether that day.
When placing the implant, we want to focus on achieving a strong hold. Due to its special affinity with titanium, bone cells gradually grow and adhere to the post to firmly anchor the implant in time. But since we're immediately loading a crown rather than allowing the bone to fully integrate first, we need to ensure the implant has a secure hold from the get-go. We can only achieve this with precise placement based on careful examination and planning, as well as adequate bone.
Even so, the implant still needs to integrate with the bone for a lasting hold, and that takes time. Even with normal biting forces the implant risks damage during this integration period. That's why we place a temporary crown a little shorter than the surrounding teeth. Those adjacent teeth will take the brunt of the biting force and not the implant.
Once the bone has fully integrated, we'll replace the temporary crown with a permanent one the proper height proportional to the other teeth. Even with the temporary crown, though, you'll still have a life-like tooth the day we removed the older one.
The key to success is planning — first determining if you meet the criteria for a same-day implant and then mapping out and carefully executing each succeeding step. Doing this will ensure your same-day implant is a success from day one.

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.
