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.

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.

Dental implants provide a number of advantages as a tooth replacement system, like durability and imperviousness to decay or gum disease. Bone naturally grows and attaches to the titanium posts, strengthening the attachment over time, and they don’t cause damage to adjacent teeth. Best of all, an implant and its crown’s life-like appearance can rejuvenate a person’s smile, transforming their appearance and self-image.
But it takes time to complete treatment with dental implants — months of healing and sufficient bone growth to anchor the implant before affixing the permanent crown. If the natural tooth requires extraction first, this may add another step — and more healing time — to the process.
In recent years, though, patients who meet certain criteria are able to shorten the time after a tooth extraction with “immediate” implants. In this case, rather than waiting for the socket to heal following a tooth extraction, the implant is placed directly into the socket immediately after the extraction. Immediate implants thus combine tooth extraction and implantation into one procedure.
For the best results, the extraction must be done very carefully to avoid as little damage as possible to surrounding tissue and bone. It’s also important for the implant to be completely immobilized within the bone with no movement at all. It will stabilize further as bone growth (or ossification) occurs over time.
It’s also possible to attach a provisional crown to the immediate implant for aesthetic purposes. This isn’t the permanent crown that will be affixed after bone growth around the implant; for that reason it’s made in such a way that it doesn’t contact its counterpart tooth in the opposing jaw. Although the implant is completely immobilized mechanically, it’s still not ready for the full forces of normal biting and chewing. After two to three months, the implant should be fully integrated with the surrounding bone and ready for the permanent crown.
Immediate implants are best for the more visible front teeth that encounter less biting force than back teeth. The technique not only reduces healing time, but enables patients to gain an “immediate” aesthetic benefit — and something worth smiling about.

If you follow the hit TV reality show Amazing Race, you know that professional-hockey-playing brothers Bates and Anthony Battaglia won the $1 million prize in the latest globe-spanning competition. You may also have witnessed Anthony removing his false front teeth from time to time — like when he had to dive for pearls in Bora Bora. Since he plans to resume his sports career, Anthony wears a partial denture to fill the gap in his classic “hockey mouth.” He has said that when he finally hangs up his skates, he will use some of his Amazing Race prize money to get new, permanent teeth. When it's time to get that new smile, Anthony, like many people, will have to choose between two good options for permanent tooth replacement.
The preferred option for most people is dental implants. In this system, tiny titanium posts substitute for the root part of your missing tooth (or teeth). These are placed beneath your gum line in a minor surgical procedure we perform right here at the dental office. The amazing thing about dental implants is that they actually fuse to your jawbone, allowing your replacement teeth to last a lifetime.
The titanium implant itself is not visible in the mouth; the part of an implant tooth that you see is the lifelike crown. Virtually indistinguishable from your natural teeth, the crown is attached to the implant above the gum line. Dental implants can be used to replace a single tooth, multiple teeth, or even all your teeth. You don't necessarily need one implant for every tooth because implants can support bridgework or even a complete set of prosthetic teeth.
The second-best option is a natural-tooth fixed bridge. In this system, we use healthy natural teeth on either side of the empty space left by a missing tooth (or teeth) as supports for one or more of the prosthetic teeth that will fill the gap. The downside is that in order to turn these healthy teeth into supports (which are referred to in dentistry as “abutments”), we need to remove some enamel and then cap them. This procedure can leave those teeth more prone to decay than they were before. But with regular dental exams and good oral hygiene on your part, bridgework can last many years.
Which system is right for you? That's a question we would be happy to help you determine... even if you haven't won a large jackpot or gone pearl diving in Bora Bora. If you've been looking forward to the day when you can have permanent replacement teeth, why wait? Contact us or schedule an appointment for a consultation. We will help you find your ideal solution to the problem of missing teeth!

Did you ever think a dentist might suggest that you have a bone graft performed as part of a standard tooth replacement procedure? Believe it or not, it's now a routine treatment — and it's not as complicated as you may think. Welcome to 21st Century dentistry!
If you're thinking about getting a tooth implant — an attractive, strong and long-lasting option for tooth replacement — here are four things you should know about bone grafting.
A bone graft may be needed prior to placing a dental implant.
One major reason why dental implants work so well as replacements for natural teeth is that they actually become fused to the underlying bone. This system offers superior durability, and a host of other advantages. Unfortunately, when a tooth is lost, the surrounding bone often begins to disappear (resorb) as well. In that case, it may be necessary to rebuild some of the bone structure before an implant can be placed effectively.
Bone regeneration for tooth implants is a routine procedure.
When it's needed, bone grafting has become a standard practice in periodontal and oral surgery. It is often performed prior to (or, occasionally, at the same time as) placing a dental implant. The grafting procedure itself can be done in the office, using local anesthesia (numbing shots, like those used for a filling) or conscious sedation (“twilight sleep”) to relieve anxiety.
The process may use a variety of high-tech materials.
The small amount of bone grafting material you need may come from a variety of sources, including human, animal or synthetic materials. Before it is used, all grafting material is processed to make it completely safe. In addition to the grafting material itself, special “guided bone regeneration” membranes and other biologically active substances may be used to promote and enhance healing.
Bone regeneration lets your body rebuild itself.
Your body uses most bone grafting materials as a scaffold or frame, over which it is able to grow its own new bone tissue. In time, the natural process of bone regeneration replaces the graft material with new bone. As we now know, maintaining sufficient bone tissue around the teeth is a crucial part of keeping up your oral health. That's why today when a tooth is going to be extracted (removed), often a bone graft will be placed at the time of extraction to preserve as much bone as possible.
