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.

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.
For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
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.

If you're one of the more than 26 million people in the U.S. with diabetes, you know first hand how the disease impacts your life. That includes your dental health — and whether or not implants are a good tooth replacement option for you.
Diabetes is actually the name for a group of diseases affecting how your body processes glucose, a simple sugar that provides energy for the body's cells. The level of glucose in the blood is regulated by insulin, a hormone produced in the pancreas. Diabetes causes the pancreas to either stop producing insulin (Type 1) or not produce enough (Type 2). Also in Type 2, the body can become unresponsive to the insulin produced.
The implications for either type are serious and can be life-threatening. If glucose levels are chronically too low or high the patient could eventually go blind, suffer nerve damage, or develop kidney disease. Diabetes also interferes with wound healing and creates a greater susceptibility for gangrene: diabetics thus have a higher risk for losing fingers, toes and limbs, and can even succumb to coma or death.
Type 2 is the most common form of diabetes. Fortunately, most people with this type can effectively manage it through diet, exercise and regular glucose monitoring; if need be, prescription medication can help regulate their levels. Even so, diabetics with their disease under control must still be alert to slower wound healing and a higher risk of infection.
Because implant placement is a minor surgical procedure, the aspects of diabetes related to healing, infection and inflammation could have an adverse impact on the ultimate success of the placement. Implant surgery creates a wound in the surrounding gum tissues and bone that will need to heal; the body's immune response in a diabetic can interfere with that process. And if infection sets in, the risks of implant failure increase.
But research has shown that diabetics with good glucose management have as high a success rate (over 95% after ten years) as non-diabetic patients. That means the implant option is a viable one for you as a diabetic — but only if you have your disease under control.
