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.

Daily oral hygiene and regular dental cleanings help keep your natural teeth and gums healthy and disease-free. But they're also a priority with dental implants. Here's why.
Unlike other restorations, an implant replaces both a tooth's crown and root, the latter by way of a titanium metal post imbedded into the jawbone. Bone cells grow and adhere to the metal surface, forming a secure and lasting hold.
But although quite durable, this hold differs significantly from natural teeth, which are actually held in place by a tough, elastic tissue called the periodontal ligament. The attachment of the ligament's tiny fibers to both tooth and bone secure the tooth in place, as well as supply it and the surrounding gums with nutrients and defensive antibodies to fight infection.
Implants don't have this relationship with the periodontal ligament. The tissues around an implant are thus susceptible to an aggressive form of periodontal (gum) disease called peri-implantitis. This kind of gum infection can progress rapidly, leading eventually to bone loss and possible failure of the implant.
Daily brushing and flossing of both natural and implant-supported teeth lowers the risk of gum disease, particularly peri-implantitis. It's also imperative that you undergo regular cleanings, at least every six months, with your dentist or dental hygienist.
These, however, won't be the typical cleanings performed on natural teeth. Hygienists don't use metal cleaning implements to remove plaque and tartar deposits because they can scratch the metal materials of the implant and crown. These microscopic scratches can then attract bacteria that trigger gum infections. Instead, they'll use instruments made of plastics or resins.
Hygienists also rely heavily on ultrasonic equipment that vibrates plaque loose on or around implants, which are then flushed away with water. The tips used with these instruments are also typically made of nylon or plastic sheathing.
Even with the extra hygiene care needed, implants still enjoy a 95% or higher survival rate after ten years. You can ensure your implants achieve that level of durability by keeping them clean and seeing your dentist at the first sign of a gum infection.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
