A fair number of people with total tooth loss have arrived at this point after a long history of dental issues. It's quite likely they've had a series of bridges or partial dentures over the years to accommodate lost teeth at various times before moving to full dentures.
For many, it often seems easier to extract any remaining teeth at some point and simply move on to a total restoration. It's often better for oral health, however, to preserve any remaining teeth for as long as possible and update restorations as needed. Dental implants could make this type of staged restoration strategy much easier to manage.
Implants are tiny metal posts surgically imbedded in a patient's jawbone. Over time, bone cells grow and adhere to the implant's titanium surface, creating a strong and durable hold. Its most familiar application is as a replacement for an individual tooth.
But because of their strength and durability, this advanced dental technology is also used to support other restorations like bridges and partial or full dentures by way of a few strategically placed implants. And it's in that role that they can be useful in planning and implementing future restoration upgrades when needed.
Under this strategy, we add implants to supplement pre-existing implants from earlier restorations to support the updated dental work. For example, we might have previously placed an implant supporting a single tooth or a small bridge. When the need later arises for a partial denture, we can add additional implants to be used with the earlier one to support the new denture.
If the earlier implants have been well-placed, we need only to add enough implants necessary to support a full denture when the time comes. How many will depend on the particular type of denture: A removable lower denture may only require one additional implant with one already in place. A fixed upper or lower denture will require enough to bring the number to between four and eight.
Taking this long-term approach can be more cost-effective in the long-run. More importantly, it can make for a smoother path for the patient and help preserve remaining teeth for as long as possible.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

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.

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.

Dental implants to replace teeth are a popular choice as much for their durability as their life-likeness. Most implants last for decades, which can result in lower long-term maintenance costs than other replacement options.
But to achieve this longevity, you must take care of your implants. You should brush and floss them daily right along with your remaining natural teeth — and continue regular semi-annual dental visits for cleanings and checkups.
You may be wondering, though: if they're made of inorganic materials, why worry with brushing them? It's true that bacterial plaque, the thin film of food particles most responsible for dental disease, doesn't affect them.
Your implants, though, don't exist in a bubble: they're imbedded in real bone, surrounded by real gum tissue and placed next to real teeth. All these other living tissues are susceptible to infection caused by plaque, even from plaque on non-organic implants.
The bone and tissues around an implant can even have a higher susceptibility to infection. This is because an implant's attachment in the jaw differs from that of natural teeth. An implant is imbedded directly into the bone; a natural tooth, on the other hand, maintains its hold through an elastic gum tissue between it and the bone called the periodontal ligament. Tiny fibers from the ligament attach to the tooth on one side and to the bone on the other.
Besides holding the tooth in place, the ligament also contains blood vessels that supply the tooth and surrounding tissues not only with nutrients but also antibodies that help fight infection. Due to the absence of a ligament connection, an implant doesn't enjoy the same level of protection from infection. Â It's much easier for tissues and teeth around an implant to become infected, and harder to stop it.
That's why prevention through daily hygiene is so important. So, be sure to brush and floss all your teeth — including implants — every day, and keep up your regular dental visits. And at the first sign of a possible infection — swollen, red or bleeding gums — see us as soon as possible for an examination.
Consider your implants a long-term investment in both your smile and dental health. Taking care of them will pay dividends for many years to come.
