ScreworCementWhichisBestforAttachingYourImplantCrown

If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.

Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.

The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.

On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.

Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.

As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

DontLetSmokingIncreaseYourChancesofImplantFailure

There are plenty of good reasons to quit smoking. Here's one more if you're considering replacing a missing tooth with a dental implant: smoking increases your risk of implant failure.

By and large, dental implants are the most reliable and durable tooth replacement option, with more than a 95% success rate after ten years. But that still leaves a small percentage that fail — and twice as many of those failures are in smokers than in non-smokers.

To understand why, we need to look at how smoking affects oral health. Besides burning and thickening the surface skin cells inside the mouth, inhaled smoke can also damage salivary glands and lead to dry mouth. Reduced saliva creates an environment friendly to bacteria, which increases the risk of infection and disease.

The nicotine in tobacco also restricts the myriad of blood vessels that course through the teeth and gums. The resulting reduced blood flow deprives teeth and gums not only of nutrients but disease-fighting antibodies. The mouth takes longer to heal and can't fight infection as well.

The key to an implant's success lies with its titanium post imbedded in the jaw bone to take the place of the tooth root. Titanium attracts bone cells, which grow and adhere to the post over a period of time and create a stronger hold. But the health effects of smoking inhibit this process. Furthermore, slower healing caused by smoking increases the risk of infection, the number one cause of early implant loss.

If you want to improve your chances for a successful implant — not to mention improve your overall health — you should quit smoking. The prospect of a dental implant could be a useful incentive to enroll in a smoking cessation program.

At the very least we suggest you stop smoking a week before implant surgery and then for at least two weeks after to help promote good healing. And you should pay close attention to your daily oral hygiene — brushing and flossing at least once — and regular, semi-annual dental visits for cleanings and checkups.

Smoking can harm your health. If you're considering an implant, it could also harm your chances of a successful outcome.

DentalImplantsCouldbeYourBestOptiontoReplaceLostTeeth

An estimated 35 million people in the United States are missing all of their teeth on at least one jaw. Your situation may not be as serious — perhaps you've only lost one tooth. But even one missing tooth could eventually impact the health of underlying bone or other teeth — and it can certainly mar an otherwise attractive smile.

Depending on other health factors, you could be an ideal candidate for a dental implant to replace that missing tooth. Since their introduction in the 1980s, implants have rapidly become the popular choice for tooth replacement. They've gained this popularity for several reasons: they're a life-like replacement that also functions like a tooth; they're adaptable to a variety of situations; and they enjoy a 95%-plus success rate.

The key to their success lies in their unique construction: they replace the tooth root, not just the crown. They accomplish this through a metal titanium post imbedded directly into the bone. The titanium attracts bone cells, which eventually grow and adhere to the post to anchor the implant securely in the jaw. This growth also deters bone loss that occurs after tooth loss and continues after acquiring other forms of removable restorations like full or partial dentures.

If implants have one drawback, though, it's their cost, especially if you have multiple lost teeth. The good news if you're missing several teeth is that each tooth does not need an implant due to their inherent strength. As few as two implants could replace three to four missing teeth or play a role as supports for other restorations like removable dentures. Some of the implants' other benefits will also carry over, including enhanced bone health.

To determine if dental implants are a good choice for your missing teeth, you'll need to undergo an evaluation of your individual dental condition (including bone health). From there we can advise you on whether implants could change your dental health and your smile.

ReplacingaMissingToothisntJustAboutImprovingYourSmile

Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.

Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.

The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).

That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.

An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.

If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

AToothlessTiger

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?

Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?

Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.

Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.

But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?

In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.

Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.

What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

If you have a gap in your grin — whatever the cause — contact us or schedule an appointment for a consultation, and find out which tooth-replacement system is right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Crowns & Bridgework.”
