You may be familiar with a dental implant used to replace a single tooth — but implant technology can do much more. Implants can also support other restorations including total teeth replacement on a jaw.
The reason they're so versatile is because implants replace the tooth root as well as the visible crown. We use a metal post, usually made of titanium, which we surgically implant in the jawbone as a root substitute. Because of a special affinity with titanium, bone around the implant grows and adheres to it and creates a durable bond.
With a single tooth replacement (the implant's original purpose when they were introduced in the 1980s) we attach a life-like porcelain crown to the individual titanium post. But with their continuing development we've adapted implants for other applications, like using a few strategically-placed implants as a stable platform for removable dentures or fixed bridges.
We're now able to use implants to support a full prosthetic (false) dental arch. Though similar in appearance to a removable denture, this particular prosthesis is permanently joined to the supporting implants with retaining screws.
Of course, the application requires careful pre-planning, which includes making sure you have enough healthy bone to support the implants. We'll also need to determine how many implants you'll need (usually four to six for this application) and create a surgical guide to place them in the best location for supporting the prosthesis. A dental technician will then create the prosthesis to match your jaw ridge contours and facial structure.
Using implants this way has a benefit other types of restorations can't provide: they may help stop future bone loss. The jawbone life cycle depends on stimulation from the attached tooth as you bite and chew — stimulation that ends when you lose the tooth. Traditional dentures and other restorations can't replicate that stimulation. Implants, on the other hand, directly encourage bone growth and can stop gradual bone loss.
If you need some form of total teeth replacement, consider one supported by implants. You may find they'll provide an excellent long-term solution to both function and appearance.
Over 26 million Americans have diabetes, a systemic condition that interferes with maintaining safe levels of blood sugar in the bloodstream. Over time, diabetes can begin to interfere with other bodily processes, including wound healing—which could affect dental care, and dental implants in particular.
Diabetes affects how the body regulates glucose, a basic sugar derived from food digestion that's the primary source of energy for cell development and function. Our bodies, though, must maintain glucose levels within a certain range — too high or too low could have adverse effects on our health. The body does this with the help of a hormone called insulin that's produced as needed by the pancreas to constantly regulate blood glucose levels.
There are two types of diabetes that interfere with the function of insulin in different ways. With Type I diabetes the pancreas stops producing insulin, forcing the patient to obtain the hormone externally through daily injections or medication. With Type II diabetes, the most common form among diabetics, the body doesn't produce enough insulin or doesn't respond adequately to the insulin that's present.
As mentioned, one of the consequences of diabetes is slow wound healing. This can have a profound effect on the body in general, but it can also potentially cause problems with dental implants. That's because implants once placed need time to integrate with the bone to achieve a strong hold. Slow wound healing caused by diabetes can slow this integration process between implant and bone, which can affect the entire implantation process.
The potential for those kinds of problems is greater if a patient's diabetes isn't under control. Patients who are effectively managing their diabetes with proper diet, exercise and medication have less trouble with wound healing, and so less chance of healing problems with implants.
All in all, though, it appears diabetics as a group have as much success with implants as the general population (above 95 percent). But it can be a smoother process if you're doing everything you can to keep your diabetes under control.
Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.
In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.
Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.
Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.
If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.
The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.
Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.
If you've lost a tooth or need to have one extracted, you have to decide how to replace it. Of all the options available none can match both the lifelikeness and function of a dental implant.
A dental implant is a prosthetic (false) tooth that mimics the root of a natural tooth. Once that implant root form fuses to the surrounding bone, we attach the crown, which is the part of the tooth you can see.
While other replacement options like bridges or dentures can restore the lifelikeness of the tooth crown, they don't replace the root. An implant's titanium post can: using a minor surgical procedure we imbed the post into the bone. Because bone cells have a natural affinity with titanium, they will grow around and adhere to the post over a few weeks after surgery. This further adds strength to the implant's hold in the bone.
Although the attachment isn't exactly like natural teeth, it can maintain this hold for many years. And because it encourages bone growth, a dental implant will help minimize bone loss, a natural consequence of losing teeth. Other replacement options can't do that.
Of course, implants are more costly than other restorations. With an attached crown, an implant can replace any number of teeth. But if you have extensive tooth loss, bridges or dentures would be more cost-effective selections.
But even then, implants could still play a role. We can strategically place a small number of implants as supports for a bridge or even a removable denture. Not only will the implants better secure their attachment, they'll also stimulate bone growth.

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.
