WhichImplantCrownAttachmentMethodisBestforYou

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.

As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.

Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.

But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.

Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.

So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.

In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

AreImplantsaNo-GoforYouConsiderTheseOtherRestorationOptions

Our primary aim as dentists is to preserve teeth. There are times, however, when preserving a tooth is no longer worth the effort and we must recommend removing it. Fortunately, extracted teeth can be replaced with a functional and attractive restoration.

Today's top tooth-replacement option is the dental implant. Composed of a titanium metal post imbedded into the jawbone, a single dental implant can replace an individual tooth or a series of implants can support other restorations for multiple teeth. Besides being incredibly life-like, dental implants are highly durable and can last for decades.

But dental implants aren't an optimal choice for everyone. Their cost often matches their status as the premier tooth replacement method. And because they require a minimum amount of bone for proper implantation, they're not always feasible for patients with extensive bone loss.

But even if dental implants aren't right for you, and you want a fixed restoration rather than dentures, you still have options. What's more, they've been around for decades!

One is a bonded crown, which works particularly well for a tooth excessively damaged by decay, excessive wear or fractures. After removing all of the damaged portions and shaping the remaining tooth, we cement a life-like crown, custom created for that particular tooth, over the remaining structure.

Besides improving appearance, a crown also protects the tooth and restores its function. One thing to remember, though, is although the crown itself is impervious to disease, the remainder of the natural tooth isn't. It's important then to brush and floss around crowned teeth like any other tooth and see a dentist regularly for cleanings.

Dental bridges are a fixed solution for extracted teeth. It's composed of prosthetic teeth to replace those missing bonded together with supporting crowns on both ends. These crowned teeth are known as abutments, and, depending on how many teeth are being replaced, we may need to increase the number of abutments to support the bridge.

Although durable, crowns or bridges typically don't match the longevity of an implant. And, implants don't require the permanent alteration of support teeth as is necessary with a bridge. But when the choice of implants isn't on the table, these traditional restorations can be an effective dental solution.

HeresWhatYouNeedToKnowAboutDentalInsuranceandChoosingaCrown

Millions of Americans rely on dental insurance to help them better afford dental care. Depending on the benefit package, an insurance policy can be useful in restoring dental health compromised by disease or injury.

But how life-like that restoration may appear is often a secondary concern with many insurance plans. For example, dental insurance will pay for a crown restoration that restores function to a tooth, but not necessarily of the highest aesthetic quality for achieving a truly life-like appearance.

To be sure, not all dental crowns are the same. Some are all metal, usually gold or silver. Some are “hybrids,” made of an interior metal shell with an outer fused porcelain shell (porcelain-fused-to-metal or PFM). In recent years all -ceramic crowns made of stronger life-like ceramics have become the most popular.

The type of crown used will depend a great deal on the type and location of the tooth. Teeth on the back of the jaw that encounter greater biting forces and are not as noticeable in the smile may do better with a metal or PFM crown. Visible side and front teeth are more likely candidates for all-ceramic. Your dentist will give you your best options as it pertains to your dental needs and appearance.

There's also a difference in crown workmanship. Dental laboratories now use milling machinery that sculpts a crown from a single block of material. Although some final handwork by skilled technicians is still necessary, milling has streamlined the process—and the cost—for producing a crown of high functioning quality.

But crowns that achieve the most natural smile appearance require more in the way of artistic craftsmanship. This in turn can increase the crown's price—beyond what many dental policies agree to cover. You may then be faced with a decision: an insurance-covered functional crown with an acceptable level of life-likeness or a more life-like crown for which you may have to pay more out-of-pocket.

Your dentist can advise you on your best options for a crown restoration, also factoring in what your insurance will cover. Ultimately, though, you'll have to weigh the kind of smile you desire with your dental situation and finances.

NewCrownsGiveBothDurabilityandBeautytoProblemTeeth

Repairing a decayed tooth may be as simple as removing the damaged tooth material and filling the void. Many filling materials can now match the color of a tooth, so the dental work is hardly noticeable.

Sometimes, though, the decay is too extensive or we've treated the tooth several times and it won't support another filling. If the tooth is still viable, we may be able to cover it with a custom crown.

Also known as a cap, a crown fits over and is securely affixed to the tooth with bonding material or cement. Crowns have been used for decades to restore teeth, but the materials they're made of have changed with time.

The original crowns were made of metal, usually gold or silver. They were strong and could hold up well to the daily forces produced by chewing or biting. They did, however, visually stand out and came to be regarded as unattractive. There were porcelain materials available that could closely mimic the life-likeness of teeth, but they could be weak and brittle.

Dentists came up with a hybrid crown that could supply strength as well as an attractive appearance. These were composed of two parts: an inner metal frame for strength overlaid with porcelain for appearance. These fused crowns were the most popular until the mid-2000s.

About that time, newer forms of porcelain came on the market that were not only attractive, but also durable. Although caution should still be taken when biting something hard, they've proven to stand up well to biting forces. Fused porcelain to metal is still in use, but usually for back teeth where biting forces are higher and the crown won't be as noticeable as on front teeth.

Crowns can also address cosmetic issues with chipped, fractured or excessively worn teeth. But with any crown you should be aware that much of the original tooth material must be removed to accommodate the fit. The altered tooth will require a crown or other restoration from then on. Crowns must also be custom-made by a dental technician in a process that can take weeks.

Still, the process can be well worth it. With proper care and maintenance, a crown could serve you and your smile well for many years to come.

DentalCrownsfortheKingofMagic

You might think David Copperfield leads a charmed life:  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.  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.
