Dental implants are considered the best tooth replacement option available. An implant replaces the root of a tooth and allows for the replacement of the crown via attachments or abutments. They not only look like a real tooth, they function like one too.
Implants, though, for some are a significant investment and may be well beyond a person's financial means if they've experienced a sudden tooth loss. For that reason, many opt for a less expensive tooth replacement option like a removable partial denture.
Later when they can afford it, a person might consider an implant. But this could pose a complication. When a tooth is missing for some time, the underlying bone doesn't rejuvenate normally because it no longer receives stimulation from the tooth. Over time, the amount of bone may diminish. Restorations like dentures can't stop this bone loss and actually aggravates it.
For proper positioning, an implant requires a certain amount of bone volume. So, it's quite possible when the time comes to replace the old restoration with an implant that there may not be enough bone available.
We may be able to overcome this bone loss with bone grafting and regeneration. A specialist such as a periodontist or oral surgeon accesses the area surgically and inserts bone graft material, usually processed material that's completely safe. Properly placed, the bone graft serves as a scaffold that, along with growth stimulators, encourages bone cells to grow.
When the bone grafting has healed enough, we're then able to place the implant. Once imbedded in the bone, one of the implant's unique qualities comes into play. The imbedded post is made of the metal titanium, which is not only bio-compatible with body tissues, it also has an affinity with bone. Bone cells will easily grow and adhere to the implant surface. This further boosts bone growth in the area and strengthens the implant's hold.
These extra procedures to build back lost bone do add to the cost and time for installing an implant. But if you're ready for a more permanent restoration for a missing tooth — not to mention better bone health — the extra time and money will be well worth it.
What's an actor's most important feature? According to Vivica A. Fox, whose most recent big-screen role was in Independence Day: Resurgence, it's what you see right up front.
"On screen, your smile and your eyes are the most inviting things that bring the audience in" she said. "Especially if you play the hot chick."
But like lots of people, Vivica reached a point where she felt her smile needed a little help in order to look its best. That's when she turned to a popular cosmetic dental treatment.
"I got veneers years ago," Ms. Fox told Dear Doctor magazine in a recent interview, "just because I had some gapping that probably only I noticed."
What exactly are dental veneers? Essentially, they are thin shells of lustrous porcelain that are permanently attached to the front surfaces of the teeth. Tough, lifelike and stain-resistant, they can cover up a number of defects in your smile — including stains, chips, cracks, and even minor spacing irregularities like the ones Vivica had.
Veneers have become the treatment of choice for Hollywood celebs — and lots of regular folks too — for many reasons. Unlike some treatments that can take many months, it takes just a few appointments to have veneers placed on your teeth. Because they are custom made just for you, they allow you to decide how bright you want your smile to be: anywhere from a natural pearly hue to a brilliant "Hollywood white." Best of all, they are easy to maintain, and can last for many years with only routine care.
To place traditional veneers, it's necessary to prepare the tooth by removing a small amount (a millimeter or two) of its enamel surface. This keeps it from feeling too big — but it also means the treatment can't be reversed, so once you get veneers, you'll always have them. In certain situations, "no-prep" or minimal-prep veneers, which require little or no removal of tooth enamel, may be an option for some people.
Veneers aren't the only way to create a better smile: Teeth whitening, crowns or orthodontic work may also be an alternative. But for many, veneers are the preferred option. What does Vivica think of hers?
"I love my veneers!" she declared, noting that they have held up well for over a decade.
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.
