It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

If you're thinking about getting dental implants, you may be curious about how long it might take. The answer depends on the health of your supporting bone.
Bone is an integral part of implant functionality as bone cells gradually grow and adhere to the newly placed implant to give it its characteristic strength. The implant also requires an adequate amount of bone to accurately position it for the best appearance outcome.
If the bone is sufficient and healthy, we can proceed with the surgical placement of the implant. The most common practice following surgery is to allow a few weeks for the bone integration described previously to take place before finally attaching the crown. With an alternative known as a “tooth in one day” procedure, we install a crown right after surgery, which gives you a full smile when you leave.
There's one caveat to this latter method, though—because the implant still requires bone integration, this immediate crown is temporary. It's designed to receive no pressure from biting or chewing, which could damage the still integrating implant. We'll install the permanent crown after the implant and bone have had time to fully mesh.
So, if your supporting bone is sound, the complete implant process may only take a few weeks. But what if it's not—what if you've lost bone and don't have enough to support an implant? In that case, the length of process time depends on the severity of the bone loss and if we're able to overcome it. In some cases, we can't, which means we'll need to consider a different restoration.
But it's often possible to regenerate lost bone by grafting bone material at the implant site. If the bone loss is moderate, it may take 2 to 4 months of regrowth after grafting before we can perform implant surgery. If it's more significant or there's disease damage to the socket, it may take longer, usually 4 to 6 months. It largely depends on the rate of bone regeneration.
In a nutshell, then, the health of your jaw's supporting bone has a lot to do with whether the implant process will take a few weeks or a few months. Regardless of the time, though, you'll gain the same result—new, functional teeth and a more attractive smile.

Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

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.

Unlike the natural tooth it replaces, a dental implant is impervious to decay. But don’t think that means you can relax your oral hygiene habits — even though the implant itself can’t be infected, the surrounding gum tissues and bone can. And if they’re not properly cared for you might eventually lose the implant.
In fact, implants may be more susceptible to problems from impacted food that becomes wedged between the gums and teeth than their natural counterparts. Natural teeth are connected to the jaw by way of a resilient, elastic tissue known as the periodontal ligament: the ligament resides in the space between the tooth root and the bone and attaches to both through tiny fibers. The bone and ligament are protected by an attachment of gum tissue that covers all of the surrounding bone and attaches to the root surface. The outer gum tissue surface is covered by a protein called keratin that makes it resistant to wear.
On the other hand, these periodontal ligament fibers don’t exist when implants are present as the implant is fastened directly to the bone. Because it doesn’t have this ligament attachment, and the gum tissues around can’t attach to the implant as with natural teeth, it may be more vulnerable to bacteria or trauma caused by food impaction. So, cleaning and caring for dental implants is just as important, if not more so than with natural teeth.
If the gums around an implant become infected and inflamed it could lead to peri-implantitis, a condition that can destroy the bone attachment between the implant and the bone. In other words, the loss of bone support can weaken the integration of the implant with the bone. As more and more attachment is lost, the implant can loosen and eventually be lost.
The best way to avoid this is with consistent daily hygiene and regular dental checkups. And, if you notice any signs of swelling or redness of the gums around an implant, contact us as soon as possible. The sooner we begin treatment to alleviate the infection, the less danger there will be of losing your implant.
