DentalImplantsandSmoking-CauseforConcern

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.

If you have questions about smoking and dental implants, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine article “Strategies to Stop Smoking.”

GettingDentalImplantsRequiresMinorSurgery

Dental implants are best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.

That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.

The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.

While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.

We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.

We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.

There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

Implant-SupportedDentures-aBetterFitwithExcessiveBoneLoss

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.

But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.

Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.

Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.

On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

KeepanEyeontheJawBoneAfteraTeenagersToothLoss

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.

Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.

There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.

Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.

Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.

Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.

Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.

DontNeglectOfficeCleaningswithDentalImplants

Semi-annual office cleanings are important for keeping teeth healthy and disease-free. If you’ve replaced some of your teeth with dental implants, though, you may be thinking they don’t need as much attention from your hygienist.

It’s quite the opposite — cleaning around implants is important, and actually requires additional attention. The reason for this relates to both how dental implants attach to the jaw and their constructive materials.

Natural teeth are held in place by the periodontal ligament with tiny fibers that attach to the teeth on one side of it and to the jawbone on the other. The ligaments and the gingival (gum) fibers (which are also attached to the tooth) provide some disease resistance to the teeth through its rich blood vessel and collagen network. Dental implants, on the other hand, anchor directly into the jawbone. The titanium integrates with the bone, which naturally attracts to the metal and grows around it, which provides the implant’s eventual attachment strength. The implant doesn’t attach to the gum tissue and won’t develop the same relationship with the periodontal ligament as natural teeth.

Bacterial plaque, the primary cause for tooth decay and periodontal (gum) disease, can collect on an implant crown just as readily as on a natural tooth. Although the materials that make up an implant can’t be affected by a plaque-induced infection, the gum tissues and supporting bone around it can. In fact, because implants lack the disease resistance of the gingival fibers and the ligament attachment, an infection can turn rapidly into a condition known as peri-implantitis that could cause bone and tissue loss and lead to the loss of the implant.

Your hygienist understands the importance of removing plaque and calculus (hardened plaque deposits) from around your dental implant. This often calls for different instruments made of plastics or resins that won’t scratch the implant’s highly polished surface. Scratches provide a haven for bacteria to collect and make it more difficult to dislodge them. Likewise, if the hygienist uses ultrasonic equipment that loosens plaque through vibration, the hygienist will often use nylon or plastic tips to minimize damage to the implant.

And don’t forget your own personal hygiene habits — they’re just as important with dental implants as with natural teeth. Keeping plaque under control, both at home and with your dentist, is crucial to longevity for your dental implants.
