If you’ve had the misfortune of losing all or most of your teeth (a condition called edentulism), you still have effective options for restoring lost form and function to your mouth. There is, of course, the traditional removable denture that’s been the mainstay for edentulism treatment for decades. If you haven’t experienced significant bone loss in the jaw, though, a fixed bridge supported by titanium implants could be a better choice.
But what if bone loss has ruled out an implant-supported fixed bridge? There’s still another option besides traditional dentures — a removable “overdenture” that fits “over” smaller diameter implants strategically placed in the jaw to support it.
A removable, implant-supported bridge offers a number of advantages for edentulism patients with significant bone loss.
Speech Enhancement. Any denture or bridge supported by implants will have a positive impact on speech ability, especially involving the upper jaw. But patients who’ve previously worn removable dentures may not see a dramatic difference but will still be able to benefit from the greater stability of the denture, particularly if the dentures were previously unstable.
Hygiene. A removable denture allows better access to implant sites for cleaning. Better hygiene reduces the risk of gum disease and further bone loss.
Long-Term Maintenance. Regardless of which type of implant supported restoration is used, it will eventually require some maintenance. A well-designed removable overdenture can make any future maintenance easier to perform.
Aesthetics. For personal satisfaction, this is often the ultimate test — how will I look? As a product of the evolving art of facial aesthetics, removable dentures supported by implants can replace lost tissues and restore balance to the face, and often produce a remarkable smile “makeover.”
To find out which restoration option is best for you, you should first undergo a thorough examination to determine the status of your facial and jaw structures, particularly the amount of bone mass still present. Ultimately, though, the decision should be the one that best fits your functional needs, while fulfilling your desires for your future smile.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.

Every day the forces you generate when you bite or chew can exert enormous pressure on your teeth. And day after day your teeth remain stable and secure, thanks to an intricate system of periodontal ligaments, attaching gum tissue and bone. The latter element is especially important — healthy bone makes healthy teeth.
And vice-versa — the same biting forces are transmitted through the tooth root to the bone via the periodontal ligament to stimulate new bone growth to replace older bone that has dissolved (resorbed). If a tooth’s missing, however, the bone doesn’t receive that stimulation, and the resorbed bone isn’t replaced at a healthy rate. In fact, you can lose up to a quarter of bone width in the first year alone after tooth loss.
And this can cause a problem when you’re looking to replace that missing tooth with what’s considered the best restorative option available: dental implants. Known for their life-likeness and durability, implants nonetheless need sufficient bone to anchor properly for the best outcome. Without it, implants simply aren’t practical.
But that doesn’t have to be the end of the story: it’s quite possible to regenerate enough bone to support implants through bone grafting. Bone material from the patient (or another donor, human, animal or synthetic) is placed under the gum at the missing tooth site to serve as a scaffold for new growth. The new bone growth will eventually replace the graft material.
The size of the graft and extent of the procedure depends of course on the amount of bone loss at the site. Loss can be kept to a minimum, though, if the graft is placed immediately after a tooth extraction, a common practice now. After a few months, the bone created through the graft is sufficient for supporting an implant and gives you the best chance for a beautiful outcome.
If you’re considering an implant for a missing tooth, you should schedule a consultation appointment with us as soon as possible. After a thorough dental exam, we’ll be able to tell you if bone grafting to support implants is a good idea for you. It adds a little more time to the overall implant process, but the results — a new, more attractive smile — will be well worth it.

Dental implants are widely considered the most durable tooth replacement option, thanks in part to how they attach to the jaw. But durable doesn't mean indestructible — you must take care of them.
Implants have a unique relationship to the jawbone compared to other restorations. We imbed a slender titanium post into the bone as a substitute for a natural tooth root. Because bone has a special affinity with the metal, it grows to and adheres to the implant to create a secure anchor. This unique attachment gives implants quite an advantage over other restorations.
It isn't superior, however, to the natural attachment of real teeth, especially in one respect: it can't match a natural attachment's infection-fighting ability. A connective tissue attachment made up of collagen fibers are attached to the tooth root protecting the underlying bone. An elastic gum tissue called the periodontal ligament lies between the tooth root and the bone and attaches to both with tiny collagen fibers. These attachments create a network of blood vessels that supply nutrients and infection-fighting agents to the bone and surrounding gum tissue.
Implants don't have this connective tissue or ligament attachment or its benefits. Of course, the implants are made of inorganic material that can't be damaged by bacterial infection. However, the gums and bone that surround them are: and because these natural tissues don't have these same biologic barriers to infection and perhaps access to the same degree of antibodies as those around natural teeth, an infection known as peri-implantitis specific to implants can develop and progress.
It's therefore just as important for you to continue brushing and flossing to remove bacterial plaque that causes infection to protect the gums and bone around your implants. You should also keep up regular office cleanings and checkups. In fact, we take special care with implants when cleaning them by using instruments that won't scratch their highly polished surfaces. Such a scratch, even a microscopic one, could attract and harbor bacteria.
There's no doubt dental implants are an excellent long-term solution for restoring your smile and mouth function. You can help extend that longevity by caring for them just as if they're your natural teeth.
