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.

DentalImplantsCouldHelpPreserveBoneAfterToothLoss

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.

Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.

But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.

As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.

Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.

Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.

This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.

If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

YouCanHaveaSuccessfulImplantOutcomeifYourDiabetesisUnderControl

Around one in ten U.S. adults have diabetes, a metabolic disease that can disrupt other aspects of a person's health like wound healing and vision. It could also cause complications with dental implants, the premier replacement choice for missing teeth.

There are two basic types of diabetes. In type 1 diabetes, the pancreas stops producing insulin, a hormone needed to regulate the amount of sugar glucose in the bloodstream. With the more prevalent type 2 diabetes, the body either doesn't produce enough insulin or doesn't respond efficiently to the insulin produced.

Uncontrolled diabetes can contribute to several dangerous health conditions. In addition to vision impairment and poor wound healing, diabetics are at higher risk for other problems like kidney disease or nerve damage. Drastic swings in blood glucose levels can also cause coma or death.

Many diabetics, though, are able to manage their condition through diet, exercise, medications and regular medical care. Even so, they may still encounter problems with wound healing, which could complicate getting a dental implant.

An implant is composed of a titanium metal post imbedded into the jawbone. Because of its affinity with titanium, bone cells naturally grow and adhere to the implant's metal surface. Several weeks after implant surgery, enough bone growth occurs to fully secure the implant within the jaw.

But this integration process may be slower for diabetics because of sluggish wound healing. It's possible for integration to not fully occur in diabetic patients after implant surgery, increasing the risk of eventually losing the implant.

Fortunately, though, evidence indicates this not to be as great a concern as once thought. A number of recent group studies comparing diabetic and non-diabetic implant patients found little difference in outcomes—both groups had similar success rates (more than 95 percent).

The only exception, though, were diabetic patients with poor glucose control, who had much slower bone integration that posed a threat to a successful implant outcome. If you're in this situation, it's better if you're first able to better control your blood glucose levels before you undergo surgery.

So, while diabetes is something to factor into your implant decision, your chances remain good for a successful outcome. Just be sure you're doing everything you can to effectively manage your diabetes.

UntreatedGumDiseaseCouldCostYouYourImplant

Your teeth can take decades of daily biting and chewing and not miss a beat. But they do have a nemesis, dental disease, which can easily get the upper hand. As a result, millions of people lose teeth each year to tooth decay and periodontal (gum) disease.

But while both the living tissue that makes up teeth and gums are susceptible to bacterial attack, the non-living materials in a life-like dental implant are impervious to disease. That being the case, you would think your implants wouldn't need as much hygiene as your other teeth.

But they still do. True, implants in themselves aren't affected by infection, but the bone and other tissues that support them can become diseased. This often happens with advanced cases of gum disease.

There is, in fact, a particular form of gum infection associated with implants called peri-implantitis ("peri"—around; "it is"—inflammation), which occurs in the gums around an implant. Once it starts, peri-implantitis can advance at a rapid pace.

This is because implants don't have the gum attachment of real teeth, which can fight and slow the advance of a gum infection. Because an implant doesn't have this attachment, any infection around it continues virtually unimpeded. If the bone supporting an implant becomes infected, it can weaken to the point that the implant fails.

But this dire scenario can be avoided with continuing hygiene and maintenance of the gum tissues surrounding the implant. You should brush and floss every day around implants to remove dental plaque, the bacterial film most responsible for dental disease, just as you do with natural teeth.

It's also important to keep up regular dental visits for cleanings to remove lingering plaque and tartar (hardened plaque). Your dentist may also notice and clean away any residual cement from the restoration, which can also cause gum inflammation.

And, you should promptly see your dentist if you notice any telltale signs of a gum infection, such as swelling, redness or bleeding, especially around implants. The quicker we diagnose and treat a case of gum disease, particularly peri-implantitis, the less likely it will endanger your implant.

ImplantsCouldHelpYouKeepRemainingTeethLonger

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.

This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.

Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.

Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.

Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.

In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.

More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.
