Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

If you’re thinking about getting dental implants, you’re in good company. Dentists have placed more than 3 million of these popular devices since their introduction in the early 1980s.
But if you have multiple missing teeth, you might think the cost of all those individual implants could put them out of your league. Yes, replacing multiple teeth with individual implants can be quite expensive—but implant technology isn’t limited to one tooth at a time. A few well-placed implants can impart their proven durability and stability to other types of restorations.
For example, we can incorporate implants into a bridge for a series of missing teeth. Conventional bridges are normally fixed in place by altering and then crowning natural teeth on each side of the missing teeth gap with a fixed row of prosthetic (false) teeth in the middle to fill it. Instead, two implants placed at the ends of the gap can support the bridge rather than natural teeth. This not only provides greater stability for the bridge, it also avoids permanent altering the natural teeth that would have been used.
Implants can also support a fixed bridge to restore complete tooth loss on a jaw. The new bridge is attached to a few strategically placed implants along the jaw line to equally distribute biting forces. This can result in a strong hold with excellent durability.
We can also use implants to improve traditional dentures. Dentures normally rest directly on the gums’ bony ridges, depending on a snug fit for stability. But bone loss, a natural consequence of missing teeth, can still occur while wearing dentures, which may in fact accelerate the rate of loss due to the appliance’s constant pressure and friction against the gums.
Instead, just a few implants placed along the jaw can, with attachments built into the denture, hold it securely in place. This not only decreases the pressure on the gums, but the natural bone growth that occurs around the implant may even deter bone loss.
Depending on your situation, there could be a viable restoration solution involving implants. Visit our office for a complete examination and evaluation to see if implants could help change your smile forever.

Dental implants are all the rage. And why not — not only are these tooth replacements life-like and highly functional, they have an amazing 95% ten-year success rate.
Some of that success is due to their unique design. Technically a root replacement, an implant's metal titanium post is surgically placed in the jawbone, where bone grows and adheres to it over time. This creates a strong connection that stands up well to the forces created by biting and chewing.
But there's more to their longevity than design. Success also depends on a careful, planned process that begins long before surgery.
It starts with a detailed oral examination to determine the best placement for the implant. Besides regular x-rays, we may also perform CT scans to create a three-dimensional view of your jaw. With this we can locate and avoid nerves, sinus cavities or other structures near the implant site.
The examination also helps us determine if you've experienced any bone loss, a normal occurrence after tooth loss. Implants require an adequate amount of bone to achieve the best position. A good position ensures future bone integration and the best appearance result.
The same attention to detail extends to the actual surgery to place the implant. We fashion the site to receive the implant by sequentially drilling larger tapered channels until we achieve the right size fit for the implant. During drilling we avoid overheating the bone, which could ultimately weaken and damage the implant's stability.
We'll also need to provide protection for the implant while it integrates with the bone. In most implantations, we do this by suturing the gum tissue over the implant. We take a different approach with a “Tooth in a Day” procedure where we attach a crown (the visible portion of the tooth) right after implant surgery. In this case we'll install a crown (which is actually temporary) that's a little shorter than the adjacent teeth. The natural teeth around it will absorb the forces produced while chewing and not the implant crown.
Focusing on these and other factors will greatly reduce the risk of implant failure. Paying careful attention to them helps ensure your new smile is a lasting one.

When it comes to replacing a missing tooth, you have several options, including a removable partial denture or a fixed bridge. But the premier choice is “the new kid on the block” at just over thirty years old: dental implants. Implants are by far the most popular tooth replacement choice among both patients and dentists.
But they also happen to be the most expensive option, at least initially. So the question is, why invest in dental implants over less costly choices?
Here are 3 reasons why implants could be well worth their price.
More Like a real tooth than other restorations. Implants can match the life-like appearance of any other replacement choice, often utilizing the same types of materials. But where they really excel is in function—how they perform while biting and chewing. This is because the dental implant’s titanium post imbedded in the jawbone replaces the tooth root. No other dental restoration can do that—or perform better when comparing the resulting functionality.
Best long-term solution. As we mentioned before, the initial implant cost is typically higher than either dentures or bridges. But you should also consider their durability compared to other choices. It could be potentially much longer—possibly decades. This is because the titanium post creates an ultra-strong hold in the jawbone as bone cells naturally grow and adhere to this particular metal. The resulting hold can withstand the daily forces generated during eating and chewing. With proper care they might even last a lifetime, and actually cost you less in the long run over other choices.
Adaptable to other types of restoration. Implants have greater uses other than as individual tooth replacements. A few strategically placed implants can also be used to support removable dentures or a fixed bridge for multiple teeth or an entire dental arch. As the technology continues to advance, implants are helping to make other restoration options stronger, more stable and longer lasting—and adding more value to your investment.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.
