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.
