While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.
This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.
In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.
One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.
If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

You probably already know that using tobacco causes significant health risks: It increases your odds of getting various cancers and coronary diseases, to name just a few. Unfortunately, not everyone is able to kick the habit, even when they know they should. Tooth loss is another issue that can cause trouble for your health, in the form of bone loss, malnutrition, and social or psychological problems. Dental implants are a great way to replace missing teeth — but does smoking complicate the process of getting implants?
The short answer is yes, smoking can make implant placement a bit riskier — but in the big picture, it doesn’t mean you can’t (or shouldn’t) have this procedure done if it’s needed.
Smoking, as you know, has harmful effects in your mouth (even leaving aside the risk of oral cancer). The hot gases can burn the oral cavity and damage salivary glands. Nicotine in smoke reduces blood flow to the soft tissues, which can affect the immune response and slow the processes of healing. At the same time, smoking promotes the growth of disease-causing oral bacteria.
How does this affect dental implants? Essentially, smoking creates a higher risk that implants may not heal properly after they are placed, and makes them more likely to fail over time. Studies have shown that smokers have an implant failure rate that’s twice as great as non-smokers. Does this mean that if you smoke, you shouldn't consider implants to replace missing or failing teeth?
Not necessarily. On the whole, implants are the most successful method of replacing missing teeth. In fact, the overall long-term survival rate of implants for both smokers and non-smokers is well over 90 percent — meaning that only a small percentage don’t work as they should. This is where it’s important to get the expert opinion of an implant specialist, who can help you decide whether implants are right for your particular situation.
If you do smoke, is there anything you can do to better your odds for having a successful dental implant? Yes: quit now! (Implants are a good excuse to start a smoking-cessation program.) But if you can’t, at least stop smoking for one week before and two weeks after implant placement. And if that is not possible, at least go on a smoking diet: restrict the number of cigarettes you smoke by 50% (we know you can at least do that!) Try to follow good oral hygiene practices at all times, and see your dentist regularly for checkups and cleanings.
When it comes to replacing a missing tooth, you have several options, including a removable partial denture or a fixed bridge. But the premier choice is “the new kid on the block” at just over thirty years old: dental implants. Implants are by far the most popular tooth replacement choice among both patients and dentists.
But they also happen to be the most expensive option, at least initially. So the question is, why invest in dental implants over less costly choices?
Here are 3 reasons why implants could be well worth their price.
More Like a real tooth than other restorations. Implants can match the life-like appearance of any other replacement choice, often utilizing the same types of materials. But where they really excel is in function—how they perform while biting and chewing. This is because the dental implant’s titanium post imbedded in the jawbone replaces the tooth root. No other dental restoration can do that—or perform better when comparing the resulting functionality.
Best long-term solution. As we mentioned before, the initial implant cost is typically higher than either dentures or bridges. But you should also consider their durability compared to other choices. It could be potentially much longer—possibly decades. This is because the titanium post creates an ultra-strong hold in the jawbone as bone cells naturally grow and adhere to this particular metal. The resulting hold can withstand the daily forces generated during eating and chewing. With proper care they might even last a lifetime, and actually cost you less in the long run over other choices.
Adaptable to other types of restoration. Implants have greater uses other than as individual tooth replacements. A few strategically placed implants can also be used to support removable dentures or a fixed bridge for multiple teeth or an entire dental arch. As the technology continues to advance, implants are helping to make other restoration options stronger, more stable and longer lasting—and adding more value to your investment.

If you smoke, you know better than anyone how a hard a habit it is to kick. If you want to quit, it helps to have a motivating reason—like lowering your risk for cancer, cardiovascular disease or similar conditions.
Here’s another reason for quitting tobacco: it could be making your teeth and gums less healthy. And, if you’re facing a restoration like dental implants, smoking can make that process harder or even increase the risk of failure.
So, to give your willpower some needed pep talk material, here are 3 reasons why smoking doesn’t mix with dental implants.
Inhaled smoke damages mouth tissues. Though you may not realize it, the smoke from your cigarette or cigar is hot enough to burn the top layer of skin cells in your mouth, which then thickens them. This could affect your salivary glands causing them to produce less saliva, which in turn could set off a chain of events that increases your risk of tooth decay or periodontal (gum) disease. The end result might be bone loss, which could make installing dental implants difficult if not impossible.
Nicotine restricts healthy blood flow. Nicotine, the chemical tobacco users crave, can restrict blood flow in the tiny vessels that course through the mouth membranes and gums. With less blood flow, these tissues may not receive enough antibodies to fight infection and fully facilitate healing, which could interfere with the integration of bone and implants that create their durable hold. Slower healing, as well as the increased chances of infection, could interrupt this integration process.
Smoking contributes to other diseases that impact oral health. Smoking’s direct effect on the mouth isn’t the only impact it could have on your oral health. As is well known, tobacco use can increase the risk of systemic conditions like cardiovascular and lung disease, and cancer. These conditions may also trigger inflammation—and a number of studies are showing this triggered inflammatory response could also affect your body’s ability to fight bacterial infections in the mouth. Less healthy teeth, gums and underlying bone work against your chances of long-term success with implants.
