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.

DenturesRequirePlanningandAttentiontoDetailtoLookNatural

Twenty-six percent of American adults between 65 and 74 have lost all their teeth to dental disease. This isn’t an appearance problem only—lack of teeth can also harm nutrition and physical well-being.

Fortunately, we have advanced restorative options that can effectively replace missing teeth. Of these, there’s a tried and true one that’s both affordable and effective: removable dentures.

Dentures are simple in design: a plastic or resin base, colored with a pinkish-red hue to resemble gums to which we attach prosthetic (false) teeth. But while the design concept isn’t complicated, the process for creating and fitting them can be quite involved: they must conform to an individual patient’s jaws and facial structure if they’re going to appear natural.

If you’re considering dentures, here’s some of what it will take to achieve a successful outcome.

Positioning the teeth. The position of the prosthetic teeth on the base greatly determines how natural they’ll appear and how well they’ll function. So, we’ll need to plan tooth placement beforehand based on your facial and jaw structures, as well as photos taken of you before tooth loss. We’ll also consider how large the teeth should be, how far to place them forward or back from the lips, and whether to include “imperfections” from your old look that you see as part of your appearance.

Simulating the gums. While the teeth are your smile’s stars, the gums are the supporting cast. It’s important that we create a denture base that attractively frames the teeth by determining how much of the gums show when you smile, or adding color and even textures to better resemble gum tissue. We can also add ridges behind the upper teeth to support speech.

Balancing the bite. Upper and lower dentures don’t operate in and of themselves—they must work cooperatively and efficiently with each other during eating or speaking. So while appearance matters, the bite’s bite adjustment or balance might matter more. That’s why we place a lot of attention into balancing and adjusting the bite after you receive your dentures to make sure you’re comfortable.

This is a detailed process that we may need to revisit from time to time to make sure your dentures’ fit remains tight and comfortable. Even so, modern advances in this traditional restoration continue to make them a solid choice for total tooth loss.

ChangesinBoneStructurecanAffectDentureFit

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.

Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.

Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.

There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.

A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.

AvoidThese4HealthProblemswithOneSimpleDenturePractice

Dentures can be an effective and affordable solution for people who've lost all their teeth. With them a person can once again eat nutritiously, speak clearly and smile confidently — and with regular care they can last for years.

As part of that ongoing care, be sure you consider one important thing with your dentures: you may want to take them out at night while you sleep. If you do you'll lessen your chances of developing these 4 health problems.

Accelerated bone loss. Traditional dentures are fitted to rest securely on the gums. This, however, creates pressure on the gums and the bony ridges beneath them that can contribute to bone loss. Wearing dentures around the clock usually accelerates this process, which could eventually lead to among other problems looser denture fit and discomfort.

Bacterial and fungal growth. Microorganisms that cause oral diseases find conducive breeding spots on the underside of dentures while they're worn in the mouth. Studies have found that people who continuously wear their dentures are more likely to have bacterial plaque and oral yeast than those that don't.

Potentially dangerous infections. Bacterial and fungal growth increases your risk of oral infections that could affect more than your mouth. A recent study of elderly nursing home residents found those who wore their dentures during sleep were over twice as likely to develop serious cases of pneumonia requiring hospitalization. It's believed bacteria harbored on the dentures can pass from the mouth to the lungs as a person breathes over them while they sleep.

Blocked salivary flow. During the night our salivary flow naturally ebbs; wearing dentures while we sleep could cause denture stomatitis, in which the tissues covered by a denture (particularly along the roof of the mouth) become inflamed and infected with yeast. It's often accompanied by angular cheilitis or cracking at the corners of the mouth that becomes infected by the same yeast.

Wearing your dentures while you sleep contributes to conditions ranging from irritating to life-threatening. To prevent such problems clean your dentures as well as the rest of your mouth regularly — and talk to your dentist whether you should leave them out when you go to bed.

SleepinginDenturesDontDoIt

Maybe you don’t like to be without teeth — ever. Or maybe you get a little forgetful sometimes. Whatever the reason, if you’re wearing your dentures to bed at night, we have one message for you: Please stop!

Sleeping in dentures can have serious health consequences. A recent study published in the Journal of Dental Research found that nursing home residents who wore their dentures to sleep were 2.3 times more likely to be hospitalized or even die of pneumonia as those who did not sleep in dentures. But how can wearing dentures at night more than double your chances of getting a lung infection?

As the study noted, pneumonia-causing bacteria can readily be moved from the mouth to the lungs simply by breathing. And dentures that are not removed at night can become breeding grounds for all kind of bacteria and fungi (such as yeast). That’s what makes them potentially dangerous.

Another condition often seen in people who wear upper dentures continually is called denture stomatitis, which is characterized by a red, inflamed palate (roof of the mouth) that has been infected with yeast. The yeast microorganisms can also infect cracked corners of the mouth, a condition known as angular cheilitis. Moreover, it has also been shown that people who sleep in dentures have higher blood levels of a protein called interleukin 6, which indicates that the body is fighting an infection. Need we go on?

Wearing dentures is supposed to improve your quality of life, not reduce it. So promote good health by taking your dentures out at night, and sticking to a good daily oral hygiene routine:

  • Remove and rinse your dentures after every meal.
  • Brush your dentures at least once a day with a soft toothbrush or denture brush and dish soap, liquid antibacterial soap, or denture cleanser (but don’t use toothpaste — it is too abrasive).
  • Store your dentures in water or a solution made for this purpose.
  • Brush your gums and tongue every day with a soft toothbrush (not the same one you clean your dentures with).
  • Rinse your dentures in clean water before you put them back in your mouth.
