Many people with diabetes are hesitant about getting dental implants because they’re under the impression their chances of failure are greater than for non-diabetics. But if you’re one of the 26 million Americans with diabetes, that isn’t necessarily so — with a little extra precaution before, during and after implant surgery.
Diabetes is a group of diseases that affect how the body processes glucose. This simple sugar is used by the body to provide energy to cells, but can also cause damage if its volume level in the bloodstream is too high. The body normally regulates this through the hormone insulin produced by the pancreas.
The pancreas in people with Type 1 diabetes doesn’t produce insulin and so they must receive an outside source of the hormone through daily injections with careful daily monitoring of glucose levels. Those with Type 2 diabetes, the most common form of the disease, don’t produce a sufficient amount of insulin or the body no longer responds to the insulin produced. For either type, abnormal glucose levels — either too high or too low — can have adverse affects on the body, including blindness, nerve damage, gangrene, coma or death.
Diabetes can also slow wound healing, increase the risk of infection, and alter the body’s inflammatory response, all of which are major concerns when placing implants. Because implant placement involves minor surgery in which a wound results, there’s been wide concern that a slower healing process could increase the risk of implant failure.
Recent studies, though, are encouraging especially for patients who have their diabetes under control through medication, diet and exercise. Patients with poor glucose control are at higher risk, because it can take longer for the bone to heal around an implant after placement. For such individuals special considerations to guard against infection may be needed during implant surgery.
In fact, the implant success rate for most diabetics is about the same as for non-diabetic patients, 95%. With proper disease management and a little extra wound care, you can be among the many that experience a favorable outcome and a more attractive smile with dental implants.
Are you interested in dental implants but a little hesitant about the surgery? Don’t be—this procedure to imbed an implant’s titanium post in the jawbone is relatively minor with little to no discomfort for most patients.
Some time before, however, we’ll need to pre-plan the surgery to pinpoint the best location for the implant, critical to achieving a solid hold and a life-like appearance. During these first visits we often create a surgical guide, a device inserted in the mouth during surgery that identifies the exact location for the hole (or channel) in the bone we’ll drill to insert the implant.
On surgery day, we’ll prepare you for a pain-free and relaxing experience. If you’re normally anxious about dental work, we may prescribe a sedative for you to take ahead of time. As we begin we’ll thoroughly numb the area with local anesthesia to ensure you won’t feel any pain.
The surgery begins with an incision through the gum tissue to access the underlying bone. Once it’s exposed, we’ll insert the surgical guide and begin a drilling sequence to gradually increase the size of the channel. This takes time because we want to avoid damaging the bone from overheating caused by friction.
Once we’ve created a channel that matches precisely the implant’s size and shape, we’ll remove the implant from its sterile packaging and immediately fit and secure it in the channel. We’ll then take x-rays to ensure it’s in the best position possible.
Satisfied we’ve properly situated and secured the implant, we’ll suture the gum tissue back in place to protect the implant with or without attaching a healing abutment to it as it fully integrates with the jawbone over the next few months (after which you’ll come back to receive your permanent crown). After a short recovery, you’ll return to full activity. Most patients only experience mild to moderate discomfort usually manageable with over-the-counter pain medication like aspirin or ibuprofen.
While implantation is a long process, you’ll be obtaining what’s considered by most dentists and their patients as the most durable and life-like tooth replacement available. Your new attractive smile will be well worth it.

Teeth-replacing dental implants not only look life-like, they’re made to last. For one thing, the metals and dental materials used in them are impervious to bacterial infection.
But that doesn’t mean implants are impervious to failure. Implants depend on the bone and other natural mouth structures for support. If the bone becomes weakened due to disease, the implant could become unstable and ultimately fail.
Peri-implantitis, the condition that can lead to this kind of failure, is a major concern for implant longevity. It’s a type of periodontal (gum) disease triggered by plaque, a thin film of food particles that can build up quickly in the absence of adequate brushing and flossing. The gum tissues around the implant become infected and inflamed.
If the infection isn’t properly treated with renewed oral hygiene and clinical plaque removal, it could spread below the gum line and begin to damage the underlying gum tissues and bone. This could destroy the all-important connection between the titanium implant post and the bone. The implant could eventually loosen and become completely detached from the bone.
The key is early intervention before the bone becomes damaged. Besides plaque removal we may also need to apply antibiotics in some form to control the growth of disease-causing bacteria. If the disease has fairly advanced we may also need to consider surgical repair to strengthen the attachment between implant and bone.
You can help to avoid peri-implantitis altogether by practicing consistent daily brushing and flossing around all your teeth including the implant, and seeing your dentist at least twice a year for cleanings and checkups. And by all means see your dentist if you notice any signs of gum swelling, redness or bleeding. Staying on top of your gum health will help not only the natural tissues and remaining teeth in your mouth, it will help preserve your implants for decades to come.
Implants are highly regarded by both dentists and patients for their versatility and durability. But it’s their life-like appearance that “seals the deal” as the restoration of choice — not only mimicking an individual tooth, but emerging from the gum line and blending indistinguishably with other teeth in color and symmetry.
To achieve this result, we must consider a few factors beforehand, particularly the amount of bone available at the intended implant site. An implant requires a certain amount of bone to properly position it for the most natural crown appearance. The bone present around adjacent teeth can also affect your appearance: in the absence of adequate bone the papillae, triangular shaped gum tissue between teeth, may not regenerate properly between the implant and the natural teeth. This can leave a noticeable void, what dentists call “black hole disease.”
Bone loss is a significant problem particularly after tooth loss. It’s quite possible for you to lose a quarter of the bone’s width in the first year after tooth loss. To avoid this, we often use bone grafting techniques immediately after extraction to lessen bone loss; if it’s already occurred we may be able to use similar reconstructive techniques to rebuild and encourage renewed bone growth. In the end, though, if there remains a significant level of bone loss it may be necessary to consider another option for tooth replacement other than implants.
The thickness of your gum tissue, a genetic trait, can also have an impact on the implant’s ultimate appearance. Thicker gum tissues are generally more resilient and easier to work with surgically. Thinner gum tissues are more susceptible to recession and tend to be more translucent, which could cause the underlying metal implant to be visible. Thus, working with thinner gum tissues requires a more delicate approach when trying to achieve a visually appealing result.
All these factors must be balanced, from implantation to final crown placement. But with careful planning and attention to detail throughout the process, many of these issues can be overcome to produce a satisfying result — a new and appealing smile.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.
