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.

NotallDentalCrownsSharetheSameQualityofLife-Likeness

Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.

Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.

In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.

Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.

The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.

All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.

However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.

Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
