Implant-SupportedDenturesCouldImproveYourBoneHealth

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.

ConsiderBoneHealthWhenDecidingBetweenImplantsandDentures

Losing permanent teeth is never good — unlike primary teeth, no natural replacements wait in the wings. But the good news is you have a number of options for replacing them with life-like prosthetic (false) teeth.

Today's premier choice is dental implants, preferred by dentists and patients alike for their durability and life-likeness. But because of their cost when replacing multiple teeth, many people opt for traditional dentures. And now dentures are easier to wear and maintain thanks to new, advanced materials and designs.

Still, there's one major area where implants have the definite edge over dentures — long-term bone health. Older bone cells die and dissolve (resorb), replaced then by newly formed cells. Teeth help perpetuate this cycle through the forces generated when we chew that travel through the roots to stimulate the formation of new bone.

But because this stimulation through a tooth ends when it's lost, new bone beneath the empty socket may not keep up with the resorption rate of older bone. As a result, you could lose as much as a quarter of normal bone width in just the first year after losing a tooth.

This bone loss will continue to accumulate even if you wear dentures, which can't replicate the bone growth stimulation of natural teeth. What's more, the constant pressure on the bony ridge of the gums can accelerate bone loss. Eventually, the firm, comfortable fit you first had with your dentures will become looser and less comfortable with the shrinking bone volume.

Implants, on the other hand, can stop bone loss and may even reverse it. This is because the titanium metal of an implant has a special affinity with bone cells that readily grow and adhere to it. This creates the anchorage responsible for the implant's durability, but it's also healthy for the bone.

Of course, this doesn't have to be a binary choice between the two restorations thanks to a new hybrid advancement that combines implants with dentures. We can install as few as two implants to support a removable denture. You'll enjoy greater stability, fit and durability with your dentures, while also improving bone health through the implants.

So before you decide on a dental restoration, be sure to discuss with us your implant options. Your oral health and appearance could benefit immensely.

ImplantSurgeryASafeandRoutineProcedure

Unlike other tooth replacement options, dental implants require a surgical procedure. But don't let your imagination run wild — the procedure is relatively minor and easy for most people to undergo.

Implants are unique among restorations because they replace a tooth's root. A metal titanium post, substituting for the root, must be surgically placed into the jawbone. While the procedure itself is simple and no more involved than a tooth extraction, it does require careful attention to detail before, during and afterward.

Our first step is to examine the target site with x-rays (often CT scanning) to pinpoint the best location for placement. This is critical because where we place the implant will have a huge bearing on how attractive and natural the implant finally appears. From this evaluation we frequently create a surgical guide.

Surgery begins with a local anesthesia to completely numb the site. You will feel no pain during the procedure and only minimal discomfort for a few days afterward. We then make small incisions in the gums to access the bone and create a small channel or hole.

Using the surgical guide, we then initiate a drilling sequence that gradually increases the size of the channel until it's the size and shape of the implant post. One thing we must do at this point is take our time: we use gentle pressure and water-cooling to avoid overheating and damaging the bone.

Once we're finished with drilling we remove the implant from its sterile packaging and imbed it directly into the prepared channel. It's then a matter of verifying the location with x-rays and then closing the gum tissue with self-absorbing sutures if necessary.

Most patients only need mild pain medication like aspirin or ibuprofen to manage discomfort afterwards. You won't even notice it in a week or less. After several weeks in which the bone grows and adheres to the implant (a process called osseointegration), you'll be ready for the final step, attaching the life-like porcelain crown to the implant.

Although the process can take several weeks to months, your discomfort should be minimal at any stage. In the end, your patience will be rewarded with a new, more attractive smile.

AvoidImplantFailurebyWatchingOutforTheseMouthProblems

There are several reasons why dental implants are so popular. Perhaps the most important, though, is their longevity: if maintained properly implants can last for decades. However, they’re not indestructible—certain mouth conditions could put them at risk for early failure. But if you address emerging problems early, you may be able to prevent that unfortunate outcome.

Your implants may be in danger, for example, if you have a teeth grinding or clenching habit. This occurs when a person involuntarily and repeatedly bites down on their teeth when not chewing or speaking. Usually triggered in adults by high stress, teeth grinding can subject both natural teeth and implants to damaging levels of force. Over time this can cause bone loss around an implant and weaken their support. It could also cause a direct break in an implant.

But there are ways to stop or at least reduce the effects of teeth grinding. One effective way is a custom-made bite guard you wear while you sleep. Made of hard plastic, the guard prevents the teeth from making solid contact with each other, reducing the amount of force generated.

A more prominent problem is periodontal (gum) disease, a bacterial infection caused by built-up dental plaque on tooth surfaces. This can trigger inflammation, a normal defensive response that when it persists for an extended period of time can damage tissues and supporting bone. It can also cause a specific form of gum disease related to implants called peri-implantitis, in which the tissues that support an implant become infected and weaken, leading eventually to possible implant failure.

If you have implants, then, you should brush and floss daily to prevent gum disease, as well as see your dentist at least every six months for cleanings and checkups. And if you notice anything like reddened, swollen or bleeding gums, see your dentist immediately. The sooner you undergo treatment, the better the outcome for your implants as well as your overall health.

Dental implants can give you years of great service and can prove to be well worth the cost. But you’ll have to stay on your guard against gum disease and other mouth conditions that could endanger them down the road.

KeepanEyeontheJawBoneAfteraTeenagersToothLoss

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.

Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.

There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.

Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.

Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.

Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.

Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.
