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.

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.

Nothing beats the form and function of a real tooth—but dental implants come pretty close. That's why they're tops among both dentists and patients for replacing missing teeth.
Much of an implant's functionality and durability can be credited to its material construction, from the titanium metal post imbedded in the jawbone to the lifelike porcelain crown attached at its other end. But an implant's “nuts and bolts” isn't the only reason why this premier dental restoration is so popular: A good portion of their success comes from the adjunct support provided by digital technology.
Without this varied array of computer-based applications used in planning, designing and installing them, implants couldn't produce the level of satisfactory outcomes they currently do. Here then are a few of the high-tech tools dentists use to make sure your implants result in a winning smile.
CBCT scanning. Implant placement requires a high degree of precision often complicated by various anatomical structures like nerves, blood vessels and sinuses within the gums and jaws. Cone Beam Computer Tomography (CBCT) scanners rotate around a patient's head, taking hundreds of digital x-ray images that are then assembled into a 3-D model image. Dentists can view this model from various angles to identify obstacles and better pinpoint the best implant locations.
Digital impressions. Dentists can also create a 3-D digital impression model of the inside of a patient's mouth that can give them views of their current teeth and gums from any angle. This aids in determining the size and type of implant so that it blends seamlessly with remaining teeth. A digital impression can also provide both the dentist and patient a preview appearance of their future smile after treatment.
3-D printed surgical guides. To accurately drill the implant site during surgery, dentists often create a custom-made device called a surgical guide that fits into the patient's mouth during the procedure. Using results from scanning and digital impressions, highly accurate guides can be created with a 3-D printer. This further ensures that the implant will be in the exact best location for the most attractive and functional outcome.
Implantology is as much art as it is science in achieving a beautiful smile. These and other digital tools help make that desirable end a reality.

When you hear the word “surgery,” your first thought might be of a high-charged operating room with a surgeon operating intently as a nurse mops sweat from their brow. While there are high-stakes surgeries, most aren’t quite that dramatic.
Dental implant surgery falls into the latter category. It does qualify as a surgical procedure because we make incisions and tissue alterations for the implant. But it’s no more rigorous than a surgical tooth extraction.
Still, if you’re new to implant surgery, it’s natural to feel some apprehension about it. To calm any nervousness, here’s a rundown of what to expect before, during and after the procedure.
Pre-Planning. Implant surgery is usually a routine affair because of meticulous planning beforehand. Often, we map out the implant site using CT scanners or other high-level imaging, identifying obstacles like nerves, blood vessels and sinus cavities, verifying there’s enough bone present to support an implant. With this information we can create a surgical plan or guide for placement in the mouth to accurately situate the implant.
Site Prep. On the day of the surgery we’ll first administer local anesthesia to numb the entire work area to pain. We’ll start with a few small gum incisions to expose the bone. Then using the surgical plan or guide, we’ll create a small channel for the implant with a drilling sequence that successively enlarges it until we achieve the best fit for the implant.
Implant Placement. Once we’ve completed drilling the channel, we’ll remove the implant from its sterile packaging and install it in the channel. After we’ve made any necessary adjustments and verified proper placement with x-rays, we’ll suture the gum tissue back into place.
After the Surgery. You might experience mild to moderate discomfort afterward that’s usually manageable with over-the-counter pain relievers like ibuprofen or acetaminophen. We can, if necessary, prescribe medication if you require something stronger. We may also prescribe an anti-bacterial mouth rinse for a short time to reduce the risk of infection.
After the implant has integrated with the bone which usually takes about 8-12 weeks, we’ll install your life-like crown or restoration. Your new smile and improved dental function will be well worth the process.
