Over 26 million Americans have diabetes, a systemic condition that interferes with maintaining safe levels of blood sugar in the bloodstream. Over time, diabetes can begin to interfere with other bodily processes, including wound healing—which could affect dental care, and dental implants in particular.
Diabetes affects how the body regulates glucose, a basic sugar derived from food digestion that's the primary source of energy for cell development and function. Our bodies, though, must maintain glucose levels within a certain range — too high or too low could have adverse effects on our health. The body does this with the help of a hormone called insulin that's produced as needed by the pancreas to constantly regulate blood glucose levels.
There are two types of diabetes that interfere with the function of insulin in different ways. With Type I diabetes the pancreas stops producing insulin, forcing the patient to obtain the hormone externally through daily injections or medication. With Type II diabetes, the most common form among diabetics, the body doesn't produce enough insulin or doesn't respond adequately to the insulin that's present.
As mentioned, one of the consequences of diabetes is slow wound healing. This can have a profound effect on the body in general, but it can also potentially cause problems with dental implants. That's because implants once placed need time to integrate with the bone to achieve a strong hold. Slow wound healing caused by diabetes can slow this integration process between implant and bone, which can affect the entire implantation process.
The potential for those kinds of problems is greater if a patient's diabetes isn't under control. Patients who are effectively managing their diabetes with proper diet, exercise and medication have less trouble with wound healing, and so less chance of healing problems with implants.
All in all, though, it appears diabetics as a group have as much success with implants as the general population (above 95 percent). But it can be a smoother process if you're doing everything you can to keep your diabetes under control.
Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

Probably a day doesn’t go by that you don’t encounter advertising for dental implants. And for good reason: implants have taken the world of dentistry by storm.
Since their inception over thirty years ago, implants have rocketed ahead of more conventional tooth replacements to become the premier choice among both dentists and patients. But what is an implant—and why are these state-of-the-art dental devices so popular?
Resemblance to natural teeth. More than any other type of dental restoration, dental implants mimic both the appearance and function of natural teeth. Just as teeth have two main parts—the roots beneath the gum surface and the visible crown—so implants have a similar construction. At their heart, implants are root replacements by way of a titanium metal post imbedded in the jawbone. To this we can permanently attach a life-like porcelain crown or even another form of restoration (more about that in a moment).
Durability. Implant materials and unique design foster a long-term success rate after ten years in the 95-plus percentile. They achieve this longevity primarily due to the use of titanium as the primary metal in the implant post. Because bone has an affinity for titanium, it will grow and adhere to the post over time to create a well-anchored hold. With proper maintenance and care implants can last for decades, making them a wise, cost-effective investment.
Added stability for other restorations. While most people associate implants with single tooth replacements, the technology has a much broader reach. For example, just a few strategically-placed implants can support a removable denture, giving this traditional restoration much more security and stability. What’s more, it can help stop bone loss, one of the main drawbacks of conventional dentures. In like fashion, implants can support a fixed bridge, eliminating the need to permanently alter adjacent teeth often used to support a conventional bridge.
With continuing advances, implant technology is becoming increasingly useful for a variety of restorative situations. Depending on your individual tooth-loss situation, dental implants could put the form and function back in your smile for many years to come.

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.
