WhatYouNeedToKnowToChoosetheRightDentalCrown

In the realm of dental restorations, not all crowns are alike. And, one type isn't necessarily superior to the others. One type of crown may work better for a particular tooth, while a different crown is better suited to another.

Therefore, knowing your options can help you make a more informed choice with your dentist regarding the best crown for your needs. Here, then, is a quick primer on the main types of dental crowns used today.

Metal crowns. Early in the last century, crowns made of gold, silver or other metals were the go-to dental restoration. Because of their strength and durability, metal crowns are still used today, mainly in back teeth that encounter heavy biting forces. Their drawback: They're decidedly not the color of natural teeth and so can stand out if they're placed in the visible "smile zone."

PFM crowns. The first crowns made with dental porcelain solved the appearance problem, but couldn't adequately handle biting forces as well as metal. Out of this came the porcelain fused to metal (PFM) crown, which contains an inner core of metal overlaid with tooth-colored porcelain. Providing both strength and life-likeness, PFM crowns were immensely popular until the mid-2000s.

All-Ceramic crowns. The development of porcelains more durable than earlier versions eventually dethroned the PFM (although the latter is still used today). Sixty percent of the crowns installed in recent years are all-ceramic, many reinforced with a strength material known as Lucite. Many all-ceramic crowns reaching the 15-year mark are still in place and functioning.

All of these crowns continue to be viable options for dental patients. The biggest factor in choosing one particular crown over another is the type of tooth involved and its location. As mentioned before, metal or PFM crowns are usually better for back teeth where durability is a higher priority than aesthetics. All-ceramics work well in high-visibility front teeth that normally encounter lighter biting forces than back teeth.

Regardless of which kind eventually caps your tooth, any of today's modern crowns will function as intended. But the best crown for you will be the one that both protects your tooth and enhances your smile.

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.

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.

CementedorScrewedWhichImplantCrownAttachmentisBestforYou

In the realm of restorative dentistry, dental implants are king. A dental implant can replace a tooth with a permanent, life-like restoration with a solid reputation for durability.

Implants are also known for one other quality — variety. Not all implants are alike, and they have varied applications for use. Available in various shapes and sizes, they can be used for a single tooth or as part of a multiple tooth bridge or overdenture. And while their basic architecture is the same, you also have two options for how the permanent crown (the visible tooth portion) attaches to the implant: screwed or cemented.

A screw attachment can securely fasten a crown to an implant without the need for cement; it also allows for easy removal for repair or replacement should the crown become damaged or worn. On the other hand, it could pose a cosmetic problem — even though the access hole for the screw may be covered with a tooth-colored filling, it could still be distinguishable from the rest of the crown. There’s also a slight risk of the crown chipping around the access hole.

A crown cemented to the implant won’t have this cosmetic issue with an access hole, and will look just like a natural tooth. But unlike a screwed crown, removing a cemented crown can be more difficult. The cement may also cause gum inflammation and potential bone loss in sensitive patients.

The condition of your mouth, the type of implant you’re receiving and other circumstances will all factor into determining which method is best for you. If we’re “immediately loading” the crown (meaning we’re affixing a temporary crown to the implant immediately after placement in the jaw), then the screw method may be more advantageous. Aesthetically speaking, though, a cemented crown may be a better option in terms of final smile appearance.

But whichever method is used, you’ll still benefit from what implants do best — help you regain the function lost from a missing tooth and change your smile for the better.

ThreeThingstoKnowAboutCrownsBeforeYourRestoration

Today’s crowns, the visible part of a tooth replacement system, can effectively mimic the shape and color of natural teeth. But not all crowns are equal — so it’s best to be well-informed before you undergo a restoration on your natural teeth such as a single crown or bridgework — or if you need a crown on a dental implant that replaces a missing tooth.

To give you a starting point, here are 3 things to keep in mind about crowns as you consider a dental restoration.

Material composition. Most crowns in years past were made of a precious metal, most notably gold. What it lacked in appearance, it made up for in performance and durability. In recent years, dental porcelain has become the popular choice because of its ability to mimic the appearance and translucent color of natural teeth. Today’s porcelains are much stronger and are used more frequently for back teeth than in years past. A common recommendation for back teeth is a hybrid crown using metal and porcelain. Metal is incorporated beneath the porcelain in this type of crown to create a strong foundation and is also used along biting surfaces for strength. Porcelain is used in the more visible areas for esthetics.

The dental technician’s level of artistry. Most dentists sub-contract crown fabrication to dental laboratory technicians who may have varying levels of experience and artistic ability. A highly skilled technician can produce a crown that blends seamlessly with the patient’s remaining natural teeth.

Take a “test drive” of your future smile. Although we as dentists adhere to certain aesthetic principles, beauty is ultimately subjective — “in the eye of the beholder.” The final product must meet your expectations and level of comfort. If available, then, consider wearing temporary “trial smile” crowns as a preview of your new smile while your permanent set is under construction. This allows you to “try out” your future smile ahead of time, so you can make recommendations and sign off on the final set before it’s finished.

Undertaking any dental restoration is an important life step, both for your health and appearance. Being well-informed — especially about the crowns that you and others will see — will help you make wise choices that lead to a satisfying outcome.
