Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

The month of May has been designated “Better Speech & Hearing Month” by the American Speech-Language-Hearing Association. Why would this be of interest to dental professionals? Because teeth are vital for good speech, and missing teeth can make it very hard to speak properly.
Speech is all about sounds, and forming sounds correctly requires proper positioning of oral structures such as the lips, tongue and teeth. For example, there are some words that are almost impossible to pronounce correctly without touching your tongue to your teeth. In fact, one of the hardest words to say without teeth…is teeth!
Missing teeth can affect speech indirectly as well, by reducing self-confidence. People who are missing front teeth often develop the habit of talking behind their hand or mumbling to avoid revealing the gap in their smile. Not being able to speak clearly and confidently can affect not only your appearance, but also your job prospects and social life. So what can you do about missing teeth?
Dental implants are today’s preferred tooth-replacement method. Implants are small titanium posts that are inserted in the jaw bone beneath your gums. They serve as “roots” to hold realistic-looking prosthetic (artificial) teeth in place. Implants can be used to replace one tooth, a group of teeth, or an entire row of teeth (upper or lower). Sometimes a dental implant can be placed the same day a failing tooth is removed so that you won’t need a second surgical procedure.
The healthy natural teeth on either side of the gap can also be used to support one or more replacement teeth. This method, called bridgework, can be used to replace a single tooth or several teeth in a row. Another option is removable dentures, which do not stay in the mouth all the time.
Each of these options has its benefits and risks. We’d be happy to discuss all of them in detail and help you decide which would be best in your own situation.

Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.

Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.
