Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

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.

Think you already know all about dentures? Answer the following questions, and see whether your understanding of false teeth is more true than false.
True or False: About one-quarter of the U.S. population has none of their own teeth left by the age of 65.
The technical term for the complete loss of all permanent teeth is edentulism, and it's a big issue, affecting 26% of adults between 65 and 74 years of age. Without treatment, many individuals not only suffer a reduced quality of life, but also risk nutritional problems and systemic health disorders. Dentures are a reliable and affordable way to replace their missing teeth.
True or False: Tooth loss has nothing to do with bone loss.
Far from being a fixed, rigid substance, bone is actually growing and changing constantly. In order for it to stay healthy, bone needs constant stimulus. For the alveolar bones of the jaw, this stimulus comes from the teeth; when they are gone, the stimulus goes too, and the bone resorbs or melts away. The missing bone mass can cause changes in facial features, difficulties with eating, speech problems and other undesirable effects.
True or False: Once the teeth are gone, there is little that can be done to mitigate bone loss.
While a certain amount of bone loss is unavoidable, it can be minimized. The techniques of bone grafting may be used to create a “scaffold” on which the body can restore its own bone tissue. Bone loss can also be limited by retaining the roots of teeth that had previous root canal treatment, even when the crowns must be removed. Perhaps the best way to limit long-term bone loss is the use of dental implants, which restores function and prevents excessive resorption from tooth loss. When tooth loss is inevitable, a pre-planned transition to dentures offers the opportunity to retain as much bone as possible, and avoid future problems.
True or False: There are many options available to make wearing dentures a fully functional and comfortable experience.
Fabricating prosthetic teeth is a blend of science and art. Not only must the appearance of the teeth and gums be made to look natural, but the fit has to be exact and the bite must be balanced. After a little practice, most people subconsciously adapt to the slightly different muscular movements required when wearing dentures. For those few who have difficulty, hybrid forms of implant-supported dentures may offer an alternative. In all cases, developing a partnership of trust between a skilled clinician and an informed patient is the best way to ensure that the experience will be a success.

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.
