Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.
But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.
This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.
This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.
But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.
Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.
Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

Getting a new implant tooth in only one day sounds too good to be true. But it's true—up to a point. Whether or not you can undergo an immediate crown replacement (attaching a crown to an implant right after surgery) will depend mostly on the underlying bone.
Traditionally, an implant crown isn't attached until several weeks after surgery to allow bone cells to grow and adhere to an implant's titanium surface (osseointegration). The gums are sutured back in place to protect the metal implant until it develops a durable hold within the bone. But this also leaves you with a noticeable missing tooth gap during the integration period.
A “tooth in a day” procedure gives you a full smile right after implant surgery. There is one catch, though—this first crown will be temporary and it won't be able to receive biting pressure.
Until the bone and implant fully integrate, attaching a full-sized permanent crown can damage the implant. To avoid this, the initial crown is slightly shorter than the future permanent crown. This prevents it from contacting solidly with teeth on the other jaw while biting or chewing, which can generate enough force to potentially damage the implant.
If you undergo an immediate-load crown on your implant, you'll have to return later for the full-length permanent crown. In the meantime, though, you'll avoid the embarrassment of a missing tooth in your smile.
With that said, the target bone must be healthy and intact for you to undergo a “tooth in a day” procedure. That isn't always the case with missing teeth—over time, bone volume can gradually diminish. The subsequent loss can complicate implant placement, which must be exact to achieve the most natural outcome. If extensive bone loss exists, you may need grafting to build up enough bone to adequately support an implant.
Even if an implant can be placed, the bone may still be too weak to allow for immediate crown placement. In that case, the traditional procedure may be the best course to allow the bone and implant to fully bond.
To determine if you're a candidate for a “tooth in a day” implant procedure, you'll first need to have a thorough dental exam that includes an assessment of bone health. If it's sound, you may be able to have a full smile right after implant surgery.

Losing your teeth can be a traumatic experience with serious consequences for your overall health. Fortunately, you have great options for replacing lost teeth that can restore both appearance and dental function.
One such option is a fixed bridge supported by dental implants. While implants are best known for single tooth replacement, they can also be used with other restorations like bridges. In this case, the bridge is screwed into a few well-placed implants to support it.
Implants can provide bridges with more security and support, and without the need to alter adjacent teeth that are commonly used for traditional tooth replacement. They may also slow or stop bone loss because the titanium in implants naturally attracts bone cells that grow and adhere to its surface and provide stimulation to the bone cells during function.
Because of these benefits an implant-supported bridge could be a life-changer that provides years of satisfaction. But we can’t simply “set them and forget them”: They require dedicated oral hygiene just like natural teeth.
While the bridge materials and implants themselves are in no danger from disease, the same can’t be said for the implant’s supporting gums and bone. Dental plaque, the main driver in gum disease, can place these tissues at risk for infection that could eventually lead to implant failure.
It’s important, then, for you to floss around your new implants to remove any plaque. This differs from regular flossing in which you work the thread between teeth. Instead, you’ll have to maneuver the floss between the bridge and gums with the help of a floss threader, a small slender tool with a loop at one end and a stiffer plastic edge at the other (similar to a sewing needle).
To use it, first run 18” of floss through the loop until you get equal lengths and then work the tail of the floss threader between the bridge and gums while holding one end of the floss. Once through, you pull the floss threader through so that the floss is on either side of the bridge. Then grab each end of the floss and pull it snug to floss up and down one side of the implant. Go to the next side and repeat this procedure for all the implants.
As an alternative, you could use an oral irrigator, which emits a pulsating spray of water to loosen and wash away plaque. Either way, though, it’s important to floss around implants to get the most life out of your bridge.

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

Losing a tooth can be traumatic, but a dental implant can dramatically turn that experience around. Providing functionality, life-like appearance and durability, implants stand out as the premier restoration for lost teeth.
For adults, that is. An older child or teenager with a missing tooth may need to wait a few more years for an implant. The reason: jaw development. A person's jaws, particular the upper jaw, continue to grow with most growth completed by early adulthood. Natural teeth with their periodontal attachments develop right alongside the jaw.
But because an implant attaches directly to the jawbone, its position is fixed: it won't change as the jaw grows and may gradually appear to sink below the gum line. That's why we wait to place an implant until most of jaw maturity has occurred after full jaw maturity. For females, we try to wait until 20 years of age and for males, usually 21 years of age. These are guidelines as some people mature faster and some slower, so a discussion with your dentist or surgeon is necessary to make an educated decision.
While we wait, we can install a temporary replacement for a child's or teenager's lost tooth, usually a partial denture or fixed modified ("Maryland") bridge. The latter affixes a prosthetic (false) tooth in the missing tooth space by attaching it to the back of natural teeth on either side with bonded dental material. It differs from a traditional bridge in that these supporting teeth aren't permanently altered and crowned to support the bridge.
During the time before implants we should understand that the area where the implant will be placed will undergo some bone deterioration, a common consequence of missing teeth. Forces generated as we chew travel through the teeth to stimulate renewing bone growth all along the jawbone. But with a lost tooth the chewing stimulation ceases at that part of the bone, slowing the growth rate and leading to gradual bone loss.
Fortunately, the titanium posts of dental implants stimulate bone growth as bone cells naturally grow and adhere to their surfaces. Before then, though, if the bone volume is diminished, we may need to graft bone material to stimulate bone growth that will enlarge the jaw bone enough for an implant to be placed.
It usually isn't a question of "if" but "when" we can provide your child with an implant for their missing tooth. In the meantime, we can prepare for that day with a temporary restoration.
