Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

With their durability, versatility and life-likeness, there’s no doubt dental implants have revolutionized teeth replacement. If you’re considering dental implants, however, there are some issues that could impact how and when you receive implants, or if you should consider another type of restoration.
Cost. Dental implants are initially more expensive than other tooth restorations, especially for multiple tooth replacement. However, be sure you consider the projected cost over the long-term, not just installation costs. Because of their durability, implants can last decades with little maintenance cost. In the long run, you may actually pay more for dental care with other types of restorations.
Bone health. Dental implants depend on a certain amount of bone to properly situate them for the best crown placement. If you’ve experienced extensive bone loss, however, there may not be enough to support the implant. This can often be overcome with grafting — immediately after extraction, at the time of implantation or a few months before implantation — to encourage bone growth. In some cases, though, bone loss may be so extensive you may need to consider an alternative restoration.
Gum Health. While implants themselves are impervious to infection, they’re supported by gum and bone tissues that can be affected. Infected tissues around an implant could eventually detach and lead to implant failure. If you have periodontal (gum) disease, we must first bring it under control and render your gums infection-free before installing implants. It’s also important to maintain effective oral hygiene and regular dental cleanings and checkups for optimum implant health.
Complications from osteoporosis. People with osteoporosis — in which the bones lose bone density and are more prone to fracture — are often treated with drugs known as bisphosphonates. In less than 1% of cases of long-term use, a patient may develop osteonecrosis in which the bone in the jaw may lose its vitality and die. As with bone loss, this condition could make implant placement difficult or impractical. Most dentists recommend stopping treatment of bisphosphonates for about three months before implant surgery.
If you have any of these issues or other complications with your oral health, be sure to discuss those with us before considering dental implants. With proper planning and care, most of these difficulties can be overcome for a successful outcome.

There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.

There are plenty of good reasons to quit smoking. Here's one more if you're considering replacing a missing tooth with a dental implant: smoking increases your risk of implant failure.
By and large, dental implants are the most reliable and durable tooth replacement option, with more than a 95% success rate after ten years. But that still leaves a small percentage that fail — and twice as many of those failures are in smokers than in non-smokers.
To understand why, we need to look at how smoking affects oral health. Besides burning and thickening the surface skin cells inside the mouth, inhaled smoke can also damage salivary glands and lead to dry mouth. Reduced saliva creates an environment friendly to bacteria, which increases the risk of infection and disease.
The nicotine in tobacco also restricts the myriad of blood vessels that course through the teeth and gums. The resulting reduced blood flow deprives teeth and gums not only of nutrients but disease-fighting antibodies. The mouth takes longer to heal and can't fight infection as well.
The key to an implant's success lies with its titanium post imbedded in the jaw bone to take the place of the tooth root. Titanium attracts bone cells, which grow and adhere to the post over a period of time and create a stronger hold. But the health effects of smoking inhibit this process. Furthermore, slower healing caused by smoking increases the risk of infection, the number one cause of early implant loss.
If you want to improve your chances for a successful implant — not to mention improve your overall health — you should quit smoking. The prospect of a dental implant could be a useful incentive to enroll in a smoking cessation program.
At the very least we suggest you stop smoking a week before implant surgery and then for at least two weeks after to help promote good healing. And you should pay close attention to your daily oral hygiene — brushing and flossing at least once — and regular, semi-annual dental visits for cleanings and checkups.
Smoking can harm your health. If you're considering an implant, it could also harm your chances of a successful outcome.

Unlike other tooth replacement options, dental implants require a surgical procedure. But don't let your imagination run wild — the procedure is relatively minor and easy for most people to undergo.
Implants are unique among restorations because they replace a tooth's root. A metal titanium post, substituting for the root, must be surgically placed into the jawbone. While the procedure itself is simple and no more involved than a tooth extraction, it does require careful attention to detail before, during and afterward.
Our first step is to examine the target site with x-rays (often CT scanning) to pinpoint the best location for placement. This is critical because where we place the implant will have a huge bearing on how attractive and natural the implant finally appears. From this evaluation we frequently create a surgical guide.
Surgery begins with a local anesthesia to completely numb the site. You will feel no pain during the procedure and only minimal discomfort for a few days afterward. We then make small incisions in the gums to access the bone and create a small channel or hole.
Using the surgical guide, we then initiate a drilling sequence that gradually increases the size of the channel until it's the size and shape of the implant post. One thing we must do at this point is take our time: we use gentle pressure and water-cooling to avoid overheating and damaging the bone.
Once we're finished with drilling we remove the implant from its sterile packaging and imbed it directly into the prepared channel. It's then a matter of verifying the location with x-rays and then closing the gum tissue with self-absorbing sutures if necessary.
Most patients only need mild pain medication like aspirin or ibuprofen to manage discomfort afterwards. You won't even notice it in a week or less. After several weeks in which the bone grows and adheres to the implant (a process called osseointegration), you'll be ready for the final step, attaching the life-like porcelain crown to the implant.
Although the process can take several weeks to months, your discomfort should be minimal at any stage. In the end, your patience will be rewarded with a new, more attractive smile.
