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.

If you would like more information on dentures supported by mini-implants, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “The ‘Great’ Mini-Implant.”

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.

SuccessfulOutcomesWithDenturesDependsonAttentiontoDetail

While dental implants are considered the gold standard for tooth replacement, removable dentures are still a viable choice, especially for patients with edentulism (complete tooth loss). Removable dentures have also undergone considerable advancement to improve their function, appearance and longevity.

But even with these advancements, dentures still require a fair amount of skill, experience and — of utmost importance — a sense of art. If you’re considering this option, long-term success depends on a careful process of construction, fit adjustment and regular checkups to maintain that fit.

Our first step is to determine exact tooth placement on each denture. Using facial features (or photos before tooth loss) we establish placement landmarks so that corresponding upper and lower teeth align properly. We also consider tooth size, their orientation in relation to the lip, and the needed space to leave between the upper and lower teeth when they are at rest. We make these determinations based on accepted standards of beauty, but also taking into account your particular comfort level with any features that might alter your appearance.

The denture’s gums must also look realistic when you smile, especially if your upper lip rises above the teeth to expose more gum tissue. We also want to match the color and texture of your natural gums, as well as incorporate palatal rugae, the little ridges behind the upper front teeth that aid with speech and chewing food.

When we first place the new dentures in your mouth, we may need to adjust them for balance between the upper and lower sets when they come together. An imbalanced fit could have an adverse effect on your ability to bite, chew and speak normally.

Your dentures should have a good, comfortable fit. Over time, however, you will encounter some degree of bone loss because you no longer have your natural teeth to stimulate bone growth and absorb the forces created during function when your teeth contact. This and other factors may cause your dentures to become loose and uncomfortable to wear. For that reason, it's important for you to visit us regularly to maintain that good fit and check the health of underlying tissues and bone.

Careful planning and denture construction help ensure your new dentures successfully restore form and function to your mouth. Regular monitoring will also ensure they continue to serve you well for as long as possible.
