Dental implants have come a long way since their introduction thirty years ago. Unlike their predecessors, today’s implants come in various shapes and sizes that can meet the precise needs of individual patients. Crown attachment has also developed some variety.
The actual implant is a titanium post surgically imbedded in the jawbone to replace the original tooth root. The restoration crown, the visible part of the implant system that resembles natural tooth, is affixed to the implant post. There are two basic methods to attach the crown: cement it to an abutment that has been installed in the implant; or screw it into the implant with a retaining screw from the underside of the crown. In the latter case, the abutment has been built into the crown.
While either method provides years of effective service, one method may work better than the other depending on the circumstance. Screw-retained crowns require no cement and are more easily removed than cemented crowns if it becomes necessary. On the other hand, the screw access hole can be visible, although the area can be filled with a tooth-colored filling; and although rare, chips near the access hole can occur. Occasionally the screw may become loose, but tightening or replacing the retaining screw is a simple matter because of the access hole.
A cemented crown looks more like a natural tooth and so is more useful in situations where cosmetics are a factor. The cement, however, can cause inflammation and contribute to bone loss in some patients when excess cement gets below the gums. Unlike a screw-retained crown, removal is more difficult and limited.
As a rule, screw-retained crowns are normally used in areas where the screw hole is not conspicuous, such as for posterior (back) teeth. They’re also more desirable than cemented when the implant is permanently crowned at the same time it’s surgically implanted, a process called “immediate loading.”
Which method of crown attachment is best for you? That depends on the implant location and other factors we would explore during a thorough pre-implant exam. Either way, the end result will be a life-like replica of your natural teeth, and a restored, vibrant smile.

She received an academy award for best supporting actress in Chicago (2002); she regularly stars in big Hollywood films like Oceans Twelve and Side Effects. And she’s been named one of People magazine’s “most beautiful people” of the year… a total of five times so far. According to big-screen heartthrob Antonio Banderas, “She has one of the most beautiful close-ups in cinematography today.”
So would it surprise you to learn that Catherine Zeta-Jones had a little help from cosmetic dentistry along the way? In her childhood, the actress said, “I was teased because I had a really flat-looking nose, and before I got braces, my teeth used to stick out a bit.” According to press reports, she has also had various dental treatments to make her teeth look whiter and more even.
Because she’s been in the spotlight since a young age, Zeta-Jones had her cosmetic dental treatments performed over a number of years. But if you’re unhappy with your smile right now, there’s no need to wait: Getting a complete “smile makeover” starts with a consultation at our office. How does it work?
We begin with a thorough dental exam to check for any underlying issues, and some basic questions, including: What do you (and don’t you) like about your smile? Are your teeth as even and as white as you’d like them to be? Is your smile too “gummy”, or do the teeth seem too large or small in proportion to your facial features? Do gaps, chips or cracked teeth detract from your appearance?
Next, working together with you, we can develop a plan to correct any perceived problems in your smile. We’ve already mentioned two of the most common ways to enhance a smile that’s less than perfect: orthodontics for straightening crooked teeth, and whitening treatments for a more brilliant smile. If your teeth are otherwise healthy, both treatments can be performed at any time — in fact, more and more of today’s orthodontic patients are adults.
Other treatments that are often used include cosmetic bonding to repair small to moderate chips or cracks in teeth; crowns (caps) to restore teeth with more extensive structural damage; and veneers to remedy a number of defects — including discoloration, small irregularities in tooth spacing, and even teeth that appear too long or too short. Plus, we have even more procedures designed to remedy specific dental issues.
Will having a better smile get you on the “most beautiful people” list? We can’t say for sure. But we think you’ll feel better about yourself… and people will notice.
