Implant-SupportedDenturesCouldBoostYourJawboneHealth

People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.

But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.

Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.

But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.

Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.

In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.

The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.

Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

For centuries, people who've lost all their teeth have worn dentures. Although materials in today's dentures are more durable and attractive than those in past generations, the basic design remains the same — prosthetic (false) teeth set in a plastic or resin base made to resemble gum tissue.

If you're thinking of obtaining dentures, don't let their simplicity deceive you: a successful outcome depends on a high degree of planning and attention to detail customized to your mouth.

Our first step is to determine the best positioning for the prosthetic teeth. It's not an “eyeball” guess — we make a number of calculations based on the shape and size of your jaws and facial features to determine the best settings within the resin base. These calculations help us answer a few important questions for determining design: how large should the teeth be? How far forward or back from the lip? How much space between the upper and lower teeth when the jaws are at rest?

We also can't forget about the artificial gums created by the base. How much your gums show when you smile depends a lot on how much your upper lip rises. We must adjust the base size to accommodate your upper lip rise so that the most attractive amount of gum shows when you smile. We also want to match as close as possible the color and texture of your natural gum tissues.

There's one other important aspect to manage: how your upper and lower dentures function together when you eat or speak. This means we must also factor your bite into the overall denture design. This may even continue after your dentures arrive: we may still need to adjust them while in your mouth to improve function and comfort.

Ill-fitting, dysfunctional and unattractive dentures can be distressing and embarrassing. But with careful planning and customization, we can help ensure your new dentures are attractive and comfortable to wear now and for years to come.

Implant-basedOverdenturesmaybeaBetterLong-TermFitOption

Although dental disease prevention has made great strides over the last century, tooth decay and periodontal (gum) disease continue to pose a major health threat. People who’ve lost all of their teeth (edentulism) or most of them suffer the most with adverse effects on their overall health, function and appearance.

Removable dentures have been the traditional and most affordable means to treat edentulism. But even with material and construction advances in recent years, dentures can still lose their fit over time as the bone in the jaw shrinks. This happens because the bone no longer has the stimulus of natural teeth and older cells can’t be replenished at a healthy rate; the continuing compression of traditional dentures on the jaw’s bony ridges compounds the problem.

As the bone shrinks the dentures become loose and uncomfortable to wear. Among other results, this poor fit can drastically affect how you eat: studies of denture wearers have found a decrease in their diet’s nutritional value because they’re eating fewer vegetables or fibrous, “chewy” foods and more foods with refined carbohydrates and fats that are easier to eat but less nutritious.

There is an alternative, though, that might slow bone loss and provide a better long-term fit: an overdenture supported by dental implants. With this appliance, a few implants are strategically installed in the upper or lower jaw. Matched attachments securely fasten the denture to the implants. In this case, the implants not the jaw ridge and gums support the denture thereby preserving the bone.

If you’re healthy enough to undergo a tooth extraction, you should be able to handle implant surgery, a minor procedure usually performed with local anesthesia and with little to no discomfort afterward. It may even be possible to retrofit your current denture to work with the implants, but that will need to be determined during the planning stages.

Although more expensive than a traditional denture, overdentures are much more affordable than fixed restorations stabilized with implants. The difference, though, is the increase in your quality of life — for better nutrition, physical health and social confidence.

NewPartialDenturesMoreComfortableandDurableThanOlderModels

While dental implants are the preferable choice for teeth replacement, your life circumstances may cause you to postpone it or some other permanent restoration. In the meantime, you need a temporary solution for your tooth loss.

Removable partial dentures (RPDs) have met this need for many years. RPDs are traditionally made of rigid, acrylic plastic resin and fasten to existing teeth with metal clasps. While effective as temporary tooth replacements, RPDs do have their drawbacks: they can be uncomfortable, develop a loose fit and are prone to wear and staining.

Recently, though, new RPDs made of a flexible type of nylon are addressing some of these drawbacks. Because the nylon material is thermoplastic (able to change shape under high heat), it can be injected into a cast mold of a patient’s mouth to create the denture base, to which life-like replacement teeth are then attached. And rather than a metal clasp, these RPDs have thin, finger-like nylon extensions that fit snugly around existing teeth at the gum line.

The new RPDs are lightweight, resistant to fracture and offer a more comfortable, snugger fit than the older RPD. And because the nylon material can be made to closely resemble gum tissue, the base can be designed to cover receding gum tissue, which may further improve the appearance of a patient’s smile.

On the downside, these new RPDs are difficult to reline or repair if they’re damaged or the fit becomes loose. And like all RPDs, they must be regularly removed and cleaned thoroughly to prevent any accumulating bacterial biofilm that could increase the risk of gum disease or tooth decay (the attachment extensions are especially susceptible to this accumulation). They should also be removed at night, since the reduction in saliva flow while you sleep can worsen bacterial buildup.

Still, the new flexible RPD is a good choice to bridge the time gap between lost teeth and a permanent restoration. They can restore lost function and improve your smile during the transition to implants or a fixed bridge.
