Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

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:Â 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.

Edentulism — the complete loss of all the permanent teeth — is a condition that affects over one-quarter of all Americans over the age of 65. For many seniors, it can be a devastating blow to their confidence and self-image. Worse, if left untreated, it may lead to nutritional problems, periodontal disease, and bone loss.
Fortunately, an affordable, time-tested treatment option is available: full denture prosthetics, or false teeth. Denture technology has changed over time, but one aspect of the process remains the same: making a superior set of dentures requires an equal blend of science and art.
To replicate the look of a patient's natural teeth, a dentist must make many choices: What size should the new teeth be? How much of them should show above the gum line? How should they be spaced? Photographs of the patient before tooth loss can help in making the decisions. We will use these, combined with clinical acumen and an artist's eye, to achieve the best aesthetic results.
But dentures not only simulate the teeth and gums they replace — they also help support the facial skeleton and the soft tissues of the lips and cheeks. Balancing the muscular forces of the jaws and tongue, they help restore natural functions like speech and eating. In order to perform these tasks properly, it is essential that they be well crafted.
At each stage of their progress, from temporary wax rims through the hard plastic resins of the final product, the dentures are carefully custom-fitted to the contours of the patient's mouth. Their bite must be balanced, meaning that upper and lower dentures come together to properly stabilize each other. This ensures that they will be comfortable to wear and will function properly.
Most people have only minor issues as they make the adjustment to wearing dentures; but for some, it's more troublesome. There are various options available to those patients, including implant-supported hybrid dentures. We can recommend alternatives based on your individual needs and preferences.

Even with all the medical know-how we possess at the dawn of the 21st century, complete tooth loss is still a big problem. In this country, more than a quarter of all adults between ages 65 and 74 have lost all of their teeth. For these individuals, removable full dentures are often still used as an affordable and effective way to replace missing teeth.
Success with dentures originates from a collaboration among dentist, laboratory technician, and, of course, the denture-wearer. Creating false teeth that look natural is as much an art as it is a science. We take a number of steps to make sure you will get the best results. These include:
- Positioning the teeth. Using facial landmarks and photographs of how you used to look before your teeth were lost helps us determine where to place each tooth and how the upper and lower teeth should line up in relation to each other. For example, we will consider what size the teeth should be; how close to the lip they should be; and how much space should exist between the upper and lower teeth when they are at rest.
- Simulating natural gums. If you are someone with a “high lip dynamic” (a lot of gum shows when you smile), it is particularly important to simulate real gum tissue in a set of full dentures. Fortunately, there are many colors and textures available to create a realistic effect. Again, photographs can be helpful in achieving this.
- Balancing the bite. We must make sure that your upper and lower dentures come together in a way that facilitates normal biting, chewing, and speech.
As a denture wearer, you will need to visit our office regularly to make sure the gum tissue and bone upon which your dentures rest stay healthy. It's common to see a gradual loss of bone in people who wear dentures at a rate that varies from person to person. This bone loss can affect the fit of your dentures and lead to other health problems, which we can address if we are monitoring you on an ongoing basis.
