YourQuestforaDentalImplantMightBeInterruptedbyBoneLoss

Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.

That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.

That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.

When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.

If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.

Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.

To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.

AnImplantRestorationCouldPreventBoneLoss

Losing teeth continues to be an all too common experience for people, especially those in their senior years. Fortunately, there are several ways to replace them, ranging from partial or full dentures to implants.

Some, though, postpone or simply choose not to replace a lost tooth, often because of the cost. But putting off a dental restoration could have a long-term impact on your health, and not in a good way. Continuing bone deterioration is one of the top consequences of delayed restoration.

Like other bones in the body, the jawbone is living tissue with cells that form, grow and eventually wear out. At the end of their life, these older cells give way to new cells. Eating and chewing play an important role in maintaining this growth cycle: the forces we generate as we chew travel up through the tooth roots to stimulate bone growth in the jaw.

When a tooth goes missing, though, the stimulus ends. Over time the bone cell replacement rate can fall off and the bone slowly loses volume. To make matters worse, bone loss can continue beyond the immediate bone underlying the tooth and affect the rest of the jawbone. The jaw can shrink in height and width, and in time become weaker overall and more susceptible to fracture.

But dental implant restorations in particular could help stop or even reverse bone deterioration at the site of the missing teeth. The titanium post implanted in the jaw attracts bone cells, which grow and adhere to its surface. Over time the bone fills in and becomes stronger.

You don't want to wait too long, though, because implants depend on a minimum amount of bone present for secure placement. You should therefore undergo an implant restoration as soon as it's practical after tooth loss. Otherwise, although we may be able to restore some of the lost bone with bone grafting, you may need to consider another restorative option.

When it comes to replacing missing teeth, time isn't on your side. But the right kind of dental restoration undertaken promptly can make for a brighter, healthier future.
