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.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
Considering all the intensive conditioning, practice and training they do, most people would expect elite athletes to be… well… healthy. And that’s generally true — except when it comes to their oral health. A major study of Olympic contenders in the 2012 London games showed that the oral health of athletes is far worse than that of the general population.
Or to put it more succinctly: “They have bodies of Adonis and a garbage mouth.”
That comment, from Dr. Paul Piccininni, a practicing dentist and member of the International Olympic Committee’s medical commission, sums up the study’s findings. In terms of the numbers, the report estimates that about one in five athletes fared worse in competition because of poor oral health, and almost half had not seen a dentist in the past year. It also found that 55 percent had cavities, 45 percent suffered from dental erosion (excessive tooth wear), and about 15 percent had moderate to severe periodontal (gum) disease.
Yet, according to Professor Ian Needleman of University College, London, lead author of the study, “Oral health could be an easy win for athletes, as the oral conditions that can affect performance are all easily preventable.”
Many of the factors that had a negative impact on the athletes are the same ones that can degrade your own oral health. A follow-up paper recently published in the British Journal of Sports Medicine identified several of these issues. One is a poor diet: The consumption of excessive carbohydrates and acidic foods and beverages (including sports drinks) can cause tooth decay and erosion of the protective enamel. Another is dehydration: Not drinking enough water can reduce the flow of healthy saliva, which can add to the damage caused by carbohydrates and acids. The effects of eating disorders (which are more commonly seen in certain sports, such as gymnastics) can also dramatically worsen an individual’s oral health.
Sound familiar? Maybe it’s because this brings up some issues that dentists have been talking about all along. While we don’t mean to nag, this study does point out that even world-class competitors have room for improvement with their oral hygiene. How about you? Whether you’re a triathlete in training, a weekend warrior or an armchair aficionado, good oral health can have a major effect on your well-being.
