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.

You might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

X-rays revolutionized dental care in the 20th Century. The same could happen in the 21st Century as cone beam computed tomography (CBCT) becomes a fixture beside the traditional x-ray machine.
CBCT made its debut in dental offices about a decade and a half ago. It utilizes the same invisible energy as traditional x-rays to create images of the face and jaw. But unlike traditional x-rays, which can only depict structures in the two dimensions of width and height, CBCT can create three-dimensional images in amazing detail.
The CBCT's x-ray projector rotates around a patient's head. As it emits a cone-shaped beam of x-rays, the device simultaneously collects anywhere from 150 to 599 distinct image views. It transmits these views to a computer that assembles them into three-dimensional images that can be viewed on a computer display.
From the data file of images, dentists can re-format a variety of views and angles of teeth, jaws and other facial bones at various levels of magnification. Because of this wide range of views, all in striking detail, CBCTs are highly useful among other things for diagnosis of malocclusions (bad bites), the size and location of infections, obstructions at possible implant sites, or jaw problems prior to surgery.
Because they expose a patient to higher doses of radiation than a standard x-ray machine, they're normally limited to more complex oral situations. That means you'll still undergo standard x-rays for most of your dental treatment needs. CBCT radiation levels are lower, however, than medical CT scans, which use a fan-shaped beam that can expose a patient to ten times the radiation of a CBCT. For dental care, a CBCT machine also produces greater image detail than an MRI.
Depending on your needs, CBCT may one day be a part of your dental care.Â With their range and accuracy, it could play a major role in helping you attain good health.
