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.

Since as many as 26 percent of older U.S. adults have lost all their teeth, there are a large number Americans who wear full removable dentures, also known as false teeth. You may be one of them.

When Giuliana Rancic, long-time host of E! News, first saw her new son, she said it was “the best single moment of my life.” Recently, on the eve of Duke's first birthday, the TV personality and reality star spoke to Dear Doctor magazine about her growing family, her battle with cancer — and the importance of starting her child off with good oral health.
“Duke will have his first visit with the dentist very soon, and since he is still a baby, we will make his visit as comfortable as possible,” Giuliana said. That's a good thought — as is the timing of her son's office visit. Her husband Bill (co-star of the couple's Style Network show) agrees. “I think the earlier you can start the checkups, the better,” he said.
The American Academy of Pediatric Dentistry concurs. In order to prevent dental problems, the AAPD states, your child should see a dentist when the first tooth appears, or no later than his or her first birthday. But since a child will lose the primary (baby) teeth anyway, is this visit really so important?
“Baby” Teeth Have a Vital Role
An age one dental visit is very important because primary teeth have several important roles: Kids rely on them for proper nutrition and speech, and don't usually begin losing them until around age 6. And since they aren't completely gone until around age 12, kids will depend on those “baby teeth” through much of childhood. Plus, they serve as guides for the proper position of the permanent teeth, and are vital to their health. That's why it's so important to care for them properly.
One major goal for the age one dental visit is to identify potential dental issues and prevent them from becoming serious problems. For example, your child will be examined for early signs of dental diseases, including baby bottle tooth decay which is a major cause of early childhood caries. Controlling these problems early can help youngsters start on the road to a lifetime of good oral health.
Besides screening your child for a number of other dental conditions or developmental problems, and assessing his or her risk for cavities, the age one visit also gives you the opportunity to ask any questions you may have about dental health in these early years. Plus, you can learn the best techniques for effectively cleaning baby's mouth and maintaining peak oral hygiene.
Breezing Through the Age-One Visit
To ease your child's way through his or her first dental visit, it helps if you're calm yourself. Try to relax, allow plenty of time, and bring along lots of activities — some favorite toys, games or stuffed animals will add to everyone's comfort level. A healthy snack, drink, and spare diapers (of course) won't go unappreciated.
“We'll probably bring some toys and snacks as reinforcements,” said Giuliana of her son's upcoming visit. So take a tip from the Rancics: The age one dental visit is a great way to start your child off right.

Today’s crowns, the visible part of a tooth replacement system, can effectively mimic the shape and color of natural teeth. But not all crowns are equal — so it’s best to be well-informed before you undergo a restoration on your natural teeth such as a single crown or bridgework — or if you need a crown on a dental implant that replaces a missing tooth.
To give you a starting point, here are 3 things to keep in mind about crowns as you consider a dental restoration.
Material composition. Most crowns in years past were made of a precious metal, most notably gold. What it lacked in appearance, it made up for in performance and durability. In recent years, dental porcelain has become the popular choice because of its ability to mimic the appearance and translucent color of natural teeth. Today’s porcelains are much stronger and are used more frequently for back teeth than in years past. A common recommendation for back teeth is a hybrid crown using metal and porcelain. Metal is incorporated beneath the porcelain in this type of crown to create a strong foundation and is also used along biting surfaces for strength. Porcelain is used in the more visible areas for esthetics.
The dental technician’s level of artistry. Most dentists sub-contract crown fabrication to dental laboratory technicians who may have varying levels of experience and artistic ability. A highly skilled technician can produce a crown that blends seamlessly with the patient’s remaining natural teeth.
Take a “test drive” of your future smile. Although we as dentists adhere to certain aesthetic principles, beauty is ultimately subjective — “in the eye of the beholder.” The final product must meet your expectations and level of comfort. If available, then, consider wearing temporary “trial smile” crowns as a preview of your new smile while your permanent set is under construction. This allows you to “try out” your future smile ahead of time, so you can make recommendations and sign off on the final set before it’s finished.
Undertaking any dental restoration is an important life step, both for your health and appearance. Being well-informed — especially about the crowns that you and others will see — will help you make wise choices that lead to a satisfying outcome.
