Dental implants are a reliable way to replace teeth. More than 95% of implants survive ten years after their installation, and many of these could conceivably continue for decades.
But that still leaves a tiny few that don't reach the ten-year mark. Some fail early because the implant didn't integrate fully with the bone to create a durable hold. But others fail later—usually for one of two major causes.
Some failures occur due to over-stressing of the implant from abnormally high biting forces, usually because of teeth grinding. People who have this involuntary habit generate excessive force as they grind their teeth, which can damage implants (as well as natural teeth). To reduce this force, a patient's dentist can fit them with a biteguard they wear in the mouth to prevent teeth from making solid contact with each other during a grinding episode.
Fortunately, teeth grinding isn't that prevalent among adults—but that can't be said about the other major cause for implant failure: periodontal (gum) disease. This is a bacterial infection caused by dental plaque, a thin, bacterial film that accumulates on teeth. The implant itself isn't affected by the infection, but the gums and underlying bone supporting the implant can be.
Implants are most in peril from a form of gum disease called Peri-implantitis, which spreads deeper into the gum tissues around implants faster than infections around natural teeth. That's because implants lack the gum attachment of real teeth, which supply a collagen barrier that slows the spread of infection. Peri-implantitis can quickly infect the supporting bone and eventually weaken its connection with the implant.
Because of its aggressiveness and speed, we must diagnose and treat peri-implantitis as soon as possible to limit any damage to the support structures around an implant. If you notice any swollen, reddened or bleeding gums, you should call your dentist as soon as possible for an examination.
And in light of this potential danger to your implants, you should also strive to prevent gum disease through daily oral hygiene. Brushing and flossing your teeth, including around your implants, removes harmful plaque buildup. This daily habit and regular dental cleanings will help you avoid a costly gum infection and ensure your implants are there for years to come.

Nothing beats the form and function of a real tooth—but dental implants come pretty close. That's why they're tops among both dentists and patients for replacing missing teeth.
Much of an implant's functionality and durability can be credited to its material construction, from the titanium metal post imbedded in the jawbone to the lifelike porcelain crown attached at its other end. But an implant's “nuts and bolts” isn't the only reason why this premier dental restoration is so popular: A good portion of their success comes from the adjunct support provided by digital technology.
Without this varied array of computer-based applications used in planning, designing and installing them, implants couldn't produce the level of satisfactory outcomes they currently do. Here then are a few of the high-tech tools dentists use to make sure your implants result in a winning smile.
CBCT scanning. Implant placement requires a high degree of precision often complicated by various anatomical structures like nerves, blood vessels and sinuses within the gums and jaws. Cone Beam Computer Tomography (CBCT) scanners rotate around a patient's head, taking hundreds of digital x-ray images that are then assembled into a 3-D model image. Dentists can view this model from various angles to identify obstacles and better pinpoint the best implant locations.
Digital impressions. Dentists can also create a 3-D digital impression model of the inside of a patient's mouth that can give them views of their current teeth and gums from any angle. This aids in determining the size and type of implant so that it blends seamlessly with remaining teeth. A digital impression can also provide both the dentist and patient a preview appearance of their future smile after treatment.
3-D printed surgical guides. To accurately drill the implant site during surgery, dentists often create a custom-made device called a surgical guide that fits into the patient's mouth during the procedure. Using results from scanning and digital impressions, highly accurate guides can be created with a 3-D printer. This further ensures that the implant will be in the exact best location for the most attractive and functional outcome.
Implantology is as much art as it is science in achieving a beautiful smile. These and other digital tools help make that desirable end a reality.

Dental implants aren't simply prosthetic teeth, but rather an innovative system that restores both smile appearance and dental function. And while an implant can indeed replace a single tooth, they can do so much more. Integrated with removable dentures or a fixed bridge, they provide a secure solution to multiple missing teeth.
Implants essentially replace a missing tooth's root, the basis for their lifelikeness and functionality. As such, they're also the most sophisticated restoration used today, requiring a high degree of technical and aesthetic skill to place them properly. In reality, implantation is more a process than a procedure.
If you're considering implants, that process begins with a comprehensive dental exam. During the exam, we'll assess the exact condition of your oral and facial structures like the length of remaining teeth, your bite and jaw dimensions. We'll use this information to plan the type and placement of your implants. The exam may also reveal problems like bone loss that might postpone your implants or suggest another form of restoration.
Using digital technology, we then locate the exact positions for your implants on the jaw to ensure the best outcome. This often results in the creation of a surgical guide, a plastic template placed over the jaw that accurately pinpoints the locations for the drilling sequence during implant surgery.
In most cases once the implants are surgically installed, gum tissue may be sutured over the implant to protect it while it integrates with the bone. In some cases, though, a visible crown may be placed immediately, so the patient can enjoy a tooth-filled smile the same day. This immediate crown, though, is temporary and will be replaced with a more durable, permanent one in a few months.
During this interim, the titanium in the implant post will attract bone cell growth, which will build up on the implant surface. This increased bone contact will help secure the implant fully in the jaw, giving the implant its signature durability.
Once the integration is complete, the permanent crown is affixed to the implant (or implants in the case of a fixed or removable dental appliance). It may have been a long road, but you'll have the closest thing to real teeth.

You feel great about your new smile, thanks to dental implants! And you may also be feeling relief as the problems with your former teeth fade into the past.
But that doesn’t mean you can drop your guard on periodontal (gum) disease. Even though implants are impervious to decay, the natural tissues supporting them are vulnerable to periodontal (gum) disease. If they become diseased, your implants could lose their bone support and eventually fail.
And that failure could happen quickly. That’s because, as life-like as they are, implants don’t have one important advantage of real teeth: an attachment to a connective tissue called the periodontal ligament. This tough but elastic ligament lies between the teeth and the bone, attaching to both with tiny extending fibers and holding the teeth in place.
And that’s not all: Because the periodontal ligament contains an abundance of blood vessels, it can supply antibodies to help fight infection. The body’s defenses may not be able to stop disease, but they can certainly inhibit its progress.
Implants can’t benefit from this infection-fighting mechanism. So, when an infection arises in the gums surrounding an implant, it can spread rapidly through a form of gum disease known as peri-implantitis (literally “inflammation around an implant”). If we don’t stop it with prompt treatment, you could lose bone support from your implant and eventually lose it, sometimes in quick fashion.
That’s why you should clean your implants everyday like you do the rest of your teeth with brushing and flossing. You should also visit us regularly for dental cleanings. A dental cleaning involving implants is similar to one with natural teeth, except the hygienist won’t use metal instruments on the implants—this could create tiny scratches on their surface. Instead, they’ll use nylon or plastic instruments or ultrasonic equipment to clean them.
You should also make a dental appointment as soon as you notice swollen, reddened or bleeding gums. If you have gum disease, we can stop the infection through treatment and restore your gums to health. This can be a long and involved process, but it’s necessary to preserve your implants.
It’s true that implants can change your life. If you want to enjoy that change for a long time, take care of your implants and the natural tissues that support them.

A dental implant as a permanent replacement for a missing tooth can match or even look better than your original tooth. How this happens takes knowledge, skill, experience, and even some art.
Here are some of the factors involved:
- Bone quantity and quality: To look and function like an original tooth, an implant must be supported by an adequate base of (jaw) bone and gum tissue. Bone has a tendency to melt away or resorb after a tooth is lost. Using new bone grafting techniques can help minimize the bone loss that occurs during healing at the extraction site. Bone grafting can also be used to rebuild lost bone at the implant site.
- Adequate bone supporting neighboring teeth: If you lose bone that supports teeth on either side of an implant, the papillae (the little pink triangles of gum tissue between the teeth) may not regenerate after the implant is placed.
- Your inborn tissue type: If your gum tissues are thin and delicate rather than thick and robust, they will be more difficult to work with. To ensure that there is sufficient gum tissue support, (gum) grafting may be necessary.
- Using the temporary crown as a template: A dental implant actually replaces a tooth root. Most dental implants are made of commercially pure titanium, which fuses with the bone in your jaw, making it very stable. The crown, the part of the tooth that is visible above the gum line, is attached to the implant; a customized temporary crown can be fitted to the implant. The temporary crown is a trial for the final crown. It can be used to assess color, shape, the appearance of your smile, and the implantâ??s function in your bite and speech. It gives you the opportunity to decide about design adjustments before the final, permanent crown is placed.
- The skill, experience, and collaboration of your dental team: Each situation is different. The final success of your implant depends on your pre-surgical assessment and diagnosis, as well as how the surgical and restorative phases of treatment are performed. The use of an outstanding dental laboratory is vital to a successful result.
