Implant-SupportedDentures-aBetterFitwithExcessiveBoneLoss

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.

But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.

Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.

Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.

On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

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.

AnImplant-SupportedDentureOffersaNumberofAdvantages

If you’ve had the misfortune of losing all or most of your teeth (a condition called edentulism), you still have effective options for restoring lost form and function to your mouth. There is, of course, the traditional removable denture that’s been the mainstay for edentulism treatment for decades. If you haven’t experienced significant bone loss in the jaw, though, a fixed bridge supported by titanium implants could be a better choice.

But what if bone loss has ruled out an implant-supported fixed bridge? There’s still another option besides traditional dentures — a removable “overdenture” that fits “over” smaller diameter implants strategically placed in the jaw to support it.

A removable, implant-supported bridge offers a number of advantages for edentulism patients with significant bone loss.

Speech Enhancement. Any denture or bridge supported by implants will have a positive impact on speech ability, especially involving the upper jaw. But patients who’ve previously worn removable dentures may not see a dramatic difference but will still be able to benefit from the greater stability of the denture, particularly if the dentures were previously unstable.

Hygiene. A removable denture allows better access to implant sites for cleaning. Better hygiene reduces the risk of gum disease and further bone loss.

Long-Term Maintenance. Regardless of which type of implant supported restoration is used, it will eventually require some maintenance. A well-designed removable overdenture can make any future maintenance easier to perform.

Aesthetics. For personal satisfaction, this is often the ultimate test — how will I look? As a product of the evolving art of facial aesthetics, removable dentures supported by implants can replace lost tissues and restore balance to the face, and often produce a remarkable smile “makeover.”

To find out which restoration option is best for you, you should first undergo a thorough examination to determine the status of your facial and jaw structures, particularly the amount of bone mass still present. Ultimately, though, the decision should be the one that best fits your functional needs, while fulfilling your desires for your future smile.

GeorgeWashingtonsFalseTeeth

Everyone knows that George Washington wore false teeth. Quick, now, what were our first President's dentures made of?

Did you say wood? Along with the cherry tree, that's one of the most persistent myths about the father of our country. In fact, Washington had several sets of dentures — made of gold, hippopotamus tusk, and animal teeth, among other things — but none of them were made of wood.

Washington's dental troubles were well documented, and likely caused some discomfort through much of his life. He began losing teeth at the age of 22, and had only one natural tooth remaining when he took office. (He lost that one before finishing his first term.) Portraits painted several years apart show scars on his cheeks and a decreasing distance between his nose and chin, indicating persistent dental problems.

Dentistry has come a long way in the two-and-a-half centuries since Washington began losing his teeth. Yet edentulism — the complete loss of all permanent teeth — remains a major public health issue. Did you know that 26% of U.S. adults between 65 and 74 years of age have no natural teeth remaining?

Tooth loss leads to loss of the underlying bone in the jaw, making a person seem older and more severe-looking (just look at those later portraits of Washington). But the problems associated with lost teeth aren't limited to cosmetic flaws. Individuals lacking teeth sometimes have trouble getting adequate nutrition, and may be at increased risk for systemic health disorders.

Fortunately, modern dentistry offers a number of ways that the problem of tooth loss can be overcome. One of the most common is still — you guessed it — removable dentures. Prosthetic teeth that are well-designed and properly fitted offer an attractive and practical replacement when the natural teeth can't be saved. Working together with you, our office can provide a set of dentures that feel, fit, and function normally — and look great too.

There are also some state-of-the art methods that can make wearing dentures an even better experience. For example, to increase stability and comfort, the whole lower denture can be supported with just two dental implants placed in the lower jaw. This is referred to as an implant supported overdenture. This approach eliminates the need for dental adhesives, and many people find it boosts their confidence as well.

If you have questions about dentures, please contact us or schedule an appointment for a consultation. You can learn more in the Dear Doctor magazine articles “Removable Full Dentures” and “Implant Overdentures for the Lower Jaw.”
