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.

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.

Installing dental implants involves more than the mechanics of placing them into the jawbone. Ultimate success — a natural and beautiful smile — requires painstaking attention to detail and artistry.
Here are a few of the factors we must consider to achieve a smile with dental implants you’ll be proud to display.
The amount of available bone. For the permanent crown to appear natural, it’s crucial to position the implant precisely. To achieve this precision requires an adequate amount of bone to be present. Unfortunately, bone loss is quite common after tooth loss; to minimize this we place bone grafts in the empty socket if at all possible after extraction to encourage bone growth. It’s also possible in some cases to perform bone grafting surgery before implants to build up bone volume.
Your genetic gum tissue type. There are basically two types of gum tissue people are born with: thin or thick. Thin tissues are more subject to wear, difficult to work with during surgery and can make it difficult to hide the metal components of an implant. Thicker tissues are easier to work with, but can have a tendency to overgrow.
Achieving a natural “emergence profile.” To look natural, the implant crown must appear to seamlessly emerge from the surrounding gum tissue. To achieve this, we must carefully plan and place the implant in the precise location in the bone, taking into account the implant shape and how far it should be placed within the bone to match the position and height of adjacent teeth and gum tissues.
Blending color shades with adjacent natural teeth. When it comes to color, everyone has subtle differences in tooth shades and hues. In fact, there are slight color variations within individual teeth, from the root to the tip of the crown. To make sure the implant blends in with adjacent teeth, it’s important to match the color incorporated into the porcelain crown with the natural crowns beside them.
These and other factors require both technical expertise and a sense of artistry. Carefully considering all of them will help ensure your dental implants result in the smile you want.

Probably a day doesn’t go by that you don’t encounter advertising for dental implants. And for good reason: implants have taken the world of dentistry by storm.
Since their inception over thirty years ago, implants have rocketed ahead of more conventional tooth replacements to become the premier choice among both dentists and patients. But what is an implant—and why are these state-of-the-art dental devices so popular?
Resemblance to natural teeth. More than any other type of dental restoration, dental implants mimic both the appearance and function of natural teeth. Just as teeth have two main parts—the roots beneath the gum surface and the visible crown—so implants have a similar construction. At their heart, implants are root replacements by way of a titanium metal post imbedded in the jawbone. To this we can permanently attach a life-like porcelain crown or even another form of restoration (more about that in a moment).
Durability. Implant materials and unique design foster a long-term success rate after ten years in the 95-plus percentile. They achieve this longevity primarily due to the use of titanium as the primary metal in the implant post. Because bone has an affinity for titanium, it will grow and adhere to the post over time to create a well-anchored hold. With proper maintenance and care implants can last for decades, making them a wise, cost-effective investment.
Added stability for other restorations. While most people associate implants with single tooth replacements, the technology has a much broader reach. For example, just a few strategically-placed implants can support a removable denture, giving this traditional restoration much more security and stability. What’s more, it can help stop bone loss, one of the main drawbacks of conventional dentures. In like fashion, implants can support a fixed bridge, eliminating the need to permanently alter adjacent teeth often used to support a conventional bridge.
With continuing advances, implant technology is becoming increasingly useful for a variety of restorative situations. Depending on your individual tooth-loss situation, dental implants could put the form and function back in your smile for many years to come.

With a 95%-plus success rate, dental implants are an effective and durable replacement for lost teeth. But we can't place them and forget them: if you don't clean and maintain them they could fail as a result of disease.
The inorganic materials that make up the implant aren't in danger of infection. But the living gums and bone that surround and support the implant are at risk. In fact, there's a particular periodontal (gum) disease involving implants called peri-implantitis (“peri” – around; implant “itis” – inflammation).
Peri-implantitis begins when the gum tissues around the implant become infected and inflamed. This happens most commonly because plaque, a thin film of bacteria and food particles, builds up on implant surfaces. Another less frequent cause is a buildup of excess cement used to bond the crown to the implant. We need to remove the built-up plaque or the excess cement during your dental visit.
If the infection isn't treated or you don't keep up effective, daily hygiene practices, the infection can grow and extend deeper into the tissues and finally the bone. This can destroy the all-important integration of bone and metal titanium post that has created the implant's strong hold. When that support becomes compromised the implant can lose its attachment and, if untreated, eventually fail.
It's important to keep an eye out for any indications you may have a gum infection around an implant. Look for redness, swelling, bleeding or pus formation. If the implant feels loose, this may mean that extensive bone loss has already occurred. If you encounter any of these signs, see us immediately for an examination.
The best approach, though, is to prevent peri-implantitis in the first place. So, brush and floss daily around your implant as you do your natural teeth. And be sure you keep up regular dental cleanings and checkups.
With proper care and maintenance you can avoid problems with disease that could affect your implant. Healthy gums and bone will ensure your implant will last for many decades to come.
