If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

Fans everywhere were recently saddened by the news of musical legend Eddie Van Halen's death. Co-founder and lead guitarist for the iconic rock group Van Halen, the 65-year-old superstar passed away from oral cancer.
Van Halen's rise to worldwide fame began in the 1970s with his unique guitar style and energetic performances, but behind the scenes, he struggled with his health. In 2000, he was successfully treated for tongue cancer. He remained cancer-free until 2018 when he was diagnosed with throat cancer to which he succumbed this past October.
Van Halen claimed the metal guitar picks he habitually held in his mouth caused his tongue cancer. It's more likely, though, that his heavy cigarette smoking and alcohol use had more to do with his cancers.
According to the American Cancer Society, most oral cancer patients are smokers and, as in Van Halen's case, are more likely to beat one form of oral cancer only to have another form arise in another part of the mouth. Add in heavy alcohol consumption, and the combined habits can increase the risk of oral cancer a hundredfold.
But there are ways to reduce that risk by making some important lifestyle changes. Here's how:
Quit tobacco. Giving up tobacco, whether smoked or smokeless, vastly lowers your oral cancer risk. It's not easy to kick the habit solo, but a medically supervised cessation program or support group can help.
Limit alcohol. If you drink heavily, consider giving up alcohol or limiting yourself to just one or two drinks a day. As with tobacco, it can be difficult doing it alone, so speak with a health professional for assistance.
Eat healthy. You can reduce your cancer risk by avoiding processed foods with nitrites or other known carcinogens. Instead, eat fresh fruits and vegetables with antioxidants that fight cancer. A healthy diet also boosts your overall dental and bodily health.
Practice hygiene. Keeping teeth and gums healthy also lowers oral cancer risk. Brush and floss daily to remove dental plaque, the bacterial film on teeth most responsible for dental disease. You should also visit us every six months for more thorough dental cleanings and checkups.
One last thing: Because oral cancer is often diagnosed in its advanced stages, be sure you see us if you notice any persistent sores or other abnormalities on your tongue or the inside of your mouth. An earlier diagnosis of oral cancer can vastly improve the long-term prognosis.
Although not as prevalent as other forms of cancer, oral cancer is among the deadliest with only a 60% five-year survival rate. Making these changes toward a healthier lifestyle can help you avoid this serious disease.

Although teeth are quite durable, we can still lose them—even all of them—to disease or injury. The good news, though, is that we have effective ways to restore teeth after they're lost. One of these, the removable denture, has given people their teeth back for several generations. And with recent advances in technology, today's dentures are even better.
Although more advanced, today's dentures share the same basic structure as those from a century ago: prosthetic (false) teeth set in a plastic resin colored to resemble the gums. The traditional denture is molded to fit snugly over an individual patient's alveolar jaw ridges, which once supported the former natural teeth. The denture stays in place primarily through a suction effect between the denture and the ridges.
Modern technology, though, has greatly improved today's dentures. Digital imaging can be used to generate highly accurate impressions of the dental ridges that can lead to denture bases with better fit. Dentists using photographs of the patient, especially in earlier years, are better able to identify facial landmarks, which enables them to position the new teeth to more closely recreate the patient's former smile.
These technological aids now help dentists to create more attractive dentures with better support and comfort. But the fit that makes this possible may not last due to a particular weakness inherent in traditional dentures—continuing bone loss. When teeth are missing, the underlying jawbone can lose bone volume over time. Dentures don't stop this process and can accelerate it due to constant friction and pressure on the dental ridges.
But a new modification incorporating dental implants with dentures can help solve these problems. By placing a few strategically positioned implants in the jawbone that then connect with the denture, the appliance not only gains more stability, but also produces less pressure on the dental ridges. In addition, bone cells naturally grow and adhere to the titanium implant posts, which helps to stop or slow bone loss.
If you've experienced total tooth loss, dentures are an affordable and effective option. Thanks to modern dental advances, you can get back the smile and dental function you once lost.
