ChoosingaScreworCementtoAttachanImplantCrown

If you've lost a tooth, you have a number of options for replacing it. Perhaps the best choice in terms of lifelikeness and durability is a dental implant.

All implants have the same basic architecture: a titanium metal post imbedded in the jawbone to replace the root; and an abutment, a metal collar that links the post with a lifelike porcelain crown. But implants can vary in how the crown attaches to the abutment and post — either cemented to the abutment or screwed through the abutment to the post.

Either method will permanently secure the crown to the implant. But there are advantages and disadvantages for each.

A screw-retained crown may better facilitate any future repair that might be needed. For a skilled dentist it's a simple matter of removing the screw and then the crown from the abutment. There's less risk of damage to the implant during repairs or crown replacement. Many dentists also prefer screws for crowns placed at the same time they're installing the implant post (a procedure called immediate loading).

The screw access hole, however, could pose a cosmetic problem. Although we can cover it over with tooth-colored filling, it may still be noticeable and unattractive especially for a tooth visible when you smile (in the smile zone). There's also the possibility the porcelain around the access hole could chip.

By contrast, cemented crowns have a smooth, unbroken surface and are aesthetically ideal for smile zone teeth. But the cement could interact poorly with gum and bone tissue in some patients, causing inflammation and possible bone loss.

And unlike screw-retained crowns, cemented crowns are difficult to remove for implant repair. We may have to drill through the crown to access the screw between the abutment and the post, and then repair it cosmetically if we use the same crown. Again, the final result may not be quite as visually appealing.

In the end, it will depend on the implant's location, how your body reacts to the cement or your dentist's preference. In either case, though, you'll have a tooth replacement that's functional, life-like and able to endure for many years to come.

GiancarloStantonGetsMajor-LeagueMouthProtection

For major-league slugger Giancarlo Stanton, 2014 was a record-breaking year. After the baseball season ended, he signed a 13-year, $325 million contract with the Miami Marlins — the biggest deal in sports history. But earlier that same year, Stanton suffered one of the worst accidents in baseball: He was hit in the face by an 88-mph fastball, sustaining multiple fractures, lacerations, and extensive dental damage.

After the accident, Stanton didn’t play for the remainder of the season. But now he’s back in Spring Training… and he’s got a not-so-secret weapon to help protect him against another injury: A custom-made face guard designed to absorb impacts and keep him from suffering further trauma.

As sports fans, we’re glad that Stanton was able to overcome his injury and get back in the game. As dentists, we’d like to remind you that you don’t have to be a major-league player to feel the harmful effects of a sports injury — and you don’t have to look far to find a way to protect yourself. In fact, you can get a custom-made mouthguard right here at the dental office.

Mouthguards have a long tradition in sports like football, boxing, and hockey. But did you know that far more Americans are injured every year playing “non-collision” sports like basketball, baseball — and even bicycling? And it doesn’t take a major-league fastball to cause a dental injury: The highest incidence of sports-related dental injuries occurs in 15-to-18-year-old males. In fact, about one-third of all dental injuries among children stem from various types of sports activities. These injuries may result in countless hours being lost from school and work, and cost significant sums for treatment and restoration.

Mouthguards have a proven track record in reducing dental and facial injuries: They are capable of absorbing the energy of a blow to the mouth, and dissipating it in a way that prevents damage to facial structures and teeth. But not all mouthguards are created equal: Custom-fabricated mouthguards, which are produced from an exact model of your mouth made right here in the dental office, offer by far the best protection. They fit better and safeguard the teeth more fully than any off-the-shelf or “boil-and-bite” type can. Plus, they’re more comfortable to wear. And let’s face it: No mouth guard can protect your teeth if you don’t wear it.

What’s more, some recent studies indicate that custom-made mouthguards may offer significant protection against concussion. An increasing awareness of the dangers that concussion may pose to athletes is one more reason why we recommend custom-made mouthguards to active people and their families.

To get his face guard, Giancarlo Stanton reportedly went to a specialist sporting-goods manufacturer in Illinois, and paid around $1,000. But you can get a custom-made mouthguard for yourself or your loved ones right at our office for a fraction of that price. And the peace of mind it can give you is… priceless.
