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.

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.

If you’re thinking about getting dental implants, you’re in good company. Dentists have placed more than 3 million of these popular devices since their introduction in the early 1980s.
But if you have multiple missing teeth, you might think the cost of all those individual implants could put them out of your league. Yes, replacing multiple teeth with individual implants can be quite expensive—but implant technology isn’t limited to one tooth at a time. A few well-placed implants can impart their proven durability and stability to other types of restorations.
For example, we can incorporate implants into a bridge for a series of missing teeth. Conventional bridges are normally fixed in place by altering and then crowning natural teeth on each side of the missing teeth gap with a fixed row of prosthetic (false) teeth in the middle to fill it. Instead, two implants placed at the ends of the gap can support the bridge rather than natural teeth. This not only provides greater stability for the bridge, it also avoids permanent altering the natural teeth that would have been used.
Implants can also support a fixed bridge to restore complete tooth loss on a jaw. The new bridge is attached to a few strategically placed implants along the jaw line to equally distribute biting forces. This can result in a strong hold with excellent durability.
We can also use implants to improve traditional dentures. Dentures normally rest directly on the gums’ bony ridges, depending on a snug fit for stability. But bone loss, a natural consequence of missing teeth, can still occur while wearing dentures, which may in fact accelerate the rate of loss due to the appliance’s constant pressure and friction against the gums.
Instead, just a few implants placed along the jaw can, with attachments built into the denture, hold it securely in place. This not only decreases the pressure on the gums, but the natural bone growth that occurs around the implant may even deter bone loss.
Depending on your situation, there could be a viable restoration solution involving implants. Visit our office for a complete examination and evaluation to see if implants could help change your smile forever.

One of the best and most successful tooth replacement choices available is the dental implant. No other restorative method is as similar in both form and function to a real tooth as an implant; and with a success rate of 95-plus percent after ten years, it’s one of the most durable.
But there can be extenuating circumstances that make obtaining an implant difficult or sometimes impossible. One possible problematic situation is the systemic disease diabetes.
Diabetes is a hormonal condition in which the body is unable to sufficiently regulate the amount of glucose (a basic sugar that provides energy to the body’s cells) within the blood stream. Normally, the pancreas produces the hormone insulin to reduce excess glucose. But diabetes interferes with this insulin production: if you have Type 1 diabetes, the pancreas has stopped producing insulin altogether; if you have the more common Type 2, the body doesn’t produce adequate insulin or it doesn’t respond sufficiently to the insulin produced.
Over time diabetes can affect other areas of health, especially wound healing. Because the condition gradually causes blood vessels to narrow and stiffen, the normal inflammatory response to disease or trauma can become prolonged. This in turn slows the rate of wound healing.
Slow wound healing can have a bearing on the recovery period just after implant surgery, especially the necessary integration process that takes place between the bone and the titanium metal implant that provides its signature strength. If that process is impeded by slow wound healing caused by diabetes, the risk increases dramatically for implant failure.
That’s the worst case scenario if you have diabetes, but only if your condition is out of control. If, however, you have your blood sugar levels well regulated through medication, diet and exercise, then your chances for implant success could easily be on par with someone without diabetes.
So if you’re diabetic and are considering dental implants for missing teeth, it’s important to discuss the possibility of obtaining them with both your dentist and the physician caring for your diabetes. With your overall healthcare team working together, there’s no reason why diabetes should stop you from enjoying this premiere restoration for missing teeth.

You’ve invested quite a bit in your new dental implants. And it truly is an investment: because of implants’ potential longevity, their long-term costs could actually be lower than other restorations whose upfront costs might be less.
But to better ensure their longevity, you’ll need to keep your implants and the natural tissues supporting them clean of bacterial plaque, a sticky biofilm that can cause periodontal (gum) disease. Although the implant itself is unaffected by disease, the natural tissues around it can be. An infection could ultimately weaken the bone supporting the implant and lead to its failure.
Such an infection involving implants could advance rapidly because they don’t have the natural defenses of the original teeth. Our natural teeth are connected to the jaw through the periodontal ligament, a collagen network that attaches to both the teeth and the bone through tiny tissue fibers. This connection also provides access to antibodies produced by the body to fight infection.
By contrast, we place implants directly into the jawbone. While this creates a very secure attachment, the implant won’t have the same connection as teeth with the body’s immune system. That means any infection that develops in surrounding tissues can spread much more rapidly—and so must be dealt with promptly.
Treating this particular form of gum disease (known as peri-implantitis) is similar to infections with natural teeth and gums, with one important difference involving the tools we use to remove plaque from them. While natural teeth can handle metal scalers and curettes, these can create microscopic scratches in the porcelain and metal surfaces of an implant and create havens for further bacterial growth. Instead, we use instruments made of plastic or resin that won’t scratch, as well as ultrasonic equipment to vibrate plaque loose.
To avoid an infection, it’s important that you brush your implants and surrounding tissues just like you would your natural teeth (be sure you use a soft-bristled brush). And keep up regular dental visits for thorough cleanings and checkups to stay ahead of any developing gum infection. Maintaining your dentures will help ensure they continue to brighten your smile for a long time.
