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.

Although they can be expensive upfront, dental implants often prove to be a wise investment in the long-term. With a success rate that outperforms other teeth replacement restorations, dental implants could be the answer to a more attractive smile that could last for decades.
But while their success rate is high (95% still functioning after ten years), they can and do occasionally fail. Of those that do, two-thirds happen in patients who smoke.
This unfortunate situation stems from smoking's overall effect on dental health. The nicotine in tobacco constricts oral blood vessels, inhibiting the flow of nutrients and antibodies to the teeth and gums. Inhaled smoke can scald the inside skin of the mouth, thickening its surface layers and damaging salivary glands leading to dry mouth.
These and other effects increase the risk for tooth decay or gum disease, which in turn makes it more likely that a smoker will lose teeth than a non-smoker and require a restoration like dental implants. And blood flow restriction caused by nicotine in turn can complicate the implant process.
Long-term implant durability depends on bone growth around the imbedded implant in the ensuing weeks after implant surgery. Because of their affinity with the titanium used in implants, bone cells readily grow and adhere to the implant. This integration process anchors the implant securely in place. But because of restricted blood flow, the healing process involved in bone integration can be impaired in smokers. Less integration may result in less stability for the implant and its long-term durability.
To increase your chances of a successful implant installation, you should consider quitting smoking and other tobacco products altogether before implant surgery. If that's too difficult, then cease from smoking for at least one week before surgery and two weeks after to better your odds of implant success. And be as meticulous as possible with daily brushing and flossing, as well as regular dental visits, to reduce your risk of disease.
There are many good reasons to quit smoking. If nothing else, do it to improve your dental health.

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.

If you've been dealing with a tooth that needs to be removed—or it's already missing—you may be looking to replace it with a dental implant. And it's a great choice: No other restoration can provide the appearance and function of a real tooth like an implant.
You and your smile are ready for it. The question is, though, are your gums and underlying bone ready? These dental structures play a critical role in an implant's stability and eventual appearance. A problem with them may make placing an implant difficult if not impossible.
An implant requires around 2.0 millimeters of bone thickness surrounding the implant surface for adequate support and to minimize the chances of gum recession. But tooth loss often leads to bone loss that can drop its thickness below this threshold. This can make placing an implant problematic.
Fortunately, though, we may be able to address the lack of sufficient bone through bone grafting. By placing grafting material within the empty socket, we create a scaffold for new bone cells to grow upon. Over time this subsequent growth may be enough to maintain an adequate thickness of bone for an implant to be placed.
The gums may also pose a problem if they've shrunk back or receded from their normal positions, as often happens because of gum disease (which may also have precipitated the tooth loss). Again, grafting procedures can help ensure there's adequate gum coverage for the implant. And healthier gums may also help protect the underlying bone from loss.
There are several techniques for placing gum tissue grafts, depending on how much recession has taken place. One procedure in particular is often used in conjunction with implant placement. A small layer of synthetic collagen material or gum tissue referred to as pa dermal apron is included with the implant when its placed. Settling into the bone socket, this apron helps thicken the gum tissues, as well as preserve the underlying bone.
During your preliminary exams, we'll assess your bone and gum health to determine if we should take any steps like these to improve them. It may add some time to the implant process, but the end result will be well worth it.

You would love to replace a troubled tooth with a dental implant. But you have one nagging concern: you also have diabetes. Could that keep you from getting an implant?
The answer, unfortunately, is yes, it might: the effect diabetes can have on the body could affect an implant's success and longevity. The key word, though, is might—it's not inevitable you'll encounter these obstacles with your implant.
Diabetes is a group of metabolic diseases that interfere with the normal levels of blood glucose, a natural sugar that is the energy source for the body's cells. Normally, the pancreas produces a hormone called insulin as needed to regulate glucose in the bloodstream. A diabetic, though either can't produce insulin or not enough, or the body doesn't respond to the insulin that is produced.
And while the condition can often be managed through diet, exercise, medication or supplemental insulin, there can still be complications like slow wound healing. High glucose can damage blood vessels, causing them to deliver less nutrients and antibodies to various parts of the body like the eyes, fingers and toes, or the kidneys. It can also affect the gums and their ability to heal.
Another possible complication from diabetes is with the body's inflammatory response. This is triggered whenever tissues in the body are diseased or injured, sealing them off from damaging the rest of the body. The response, however, can become chronic in diabetics, which could damage otherwise healthy tissues.
Both of these complications can disrupt the process for getting an implant. Like other surgical procedures, implantation disrupts the gum tissues. They will need to heal; likewise, the implant itself must integrate fully with the bone in which it's inserted. Both healing and bone integration might be impeded by slow wound healing and chronic inflammation.
Again, it might. In reality, as a number of studies comparing implant outcomes between diabetics and non-diabetics has shown, there is little difference in the success rate, provided the diabetes is under control. Diabetics with well-managed glucose can have success rates above 95%, well within the normal range.
An implant restoration is a decision you should make with your dentist. But if you're doing a good job managing your diabetes, your chances of a successful outcome are good.
