Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.
Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they're replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.
Removable dentures can't provide this stimulation. In fact, the pressure generated as they compress the gums' bony ridges can even accelerate bone loss. That's why over time a denture's fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.
In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.
Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant's hold in the jaw.
Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.
Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.

Are you interested in dental implants but a little hesitant about the surgery? Don’t be—this procedure to imbed an implant’s titanium post in the jawbone is relatively minor with little to no discomfort for most patients.
Some time before, however, we’ll need to pre-plan the surgery to pinpoint the best location for the implant, critical to achieving a solid hold and a life-like appearance. During these first visits we often create a surgical guide, a device inserted in the mouth during surgery that identifies the exact location for the hole (or channel) in the bone we’ll drill to insert the implant.
On surgery day, we’ll prepare you for a pain-free and relaxing experience. If you’re normally anxious about dental work, we may prescribe a sedative for you to take ahead of time. As we begin we’ll thoroughly numb the area with local anesthesia to ensure you won’t feel any pain.
The surgery begins with an incision through the gum tissue to access the underlying bone. Once it’s exposed, we’ll insert the surgical guide and begin a drilling sequence to gradually increase the size of the channel. This takes time because we want to avoid damaging the bone from overheating caused by friction.
Once we’ve created a channel that matches precisely the implant’s size and shape, we’ll remove the implant from its sterile packaging and immediately fit and secure it in the channel. We’ll then take x-rays to ensure it’s in the best position possible.
Satisfied we’ve properly situated and secured the implant, we’ll suture the gum tissue back in place to protect the implant with or without attaching a healing abutment to it as it fully integrates with the jawbone over the next few months (after which you’ll come back to receive your permanent crown). After a short recovery, you’ll return to full activity. Most patients only experience mild to moderate discomfort usually manageable with over-the-counter pain medication like aspirin or ibuprofen.
While implantation is a long process, you’ll be obtaining what’s considered by most dentists and their patients as the most durable and life-like tooth replacement available. Your new attractive smile will be well worth it.

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.

While there’s usually a period of months between implant placement and the permanent crown, a new technique known as same-day tooth replacement installs both the implant and a temporary crown during the same visit. But be advised — it does have its risks and isn’t for everyone.
Successful same-day replacements require special attention during the three phases for implants: the removal (extraction) of the existing tooth; placement of the implant in the bone; and attachment of the crown, the visible tooth, to the implant. The tooth extraction lays the foundation for the entire process; the extraction procedure must be performed carefully to avoid undue damage to the socket. In addition, if infection or disease has compromised the site, an implant may not be possible immediately.
The implant must then be placed in the bone so that it’s stable and immovable. All implants stabilize with time as the bone grows and adheres to them, but we need greater stability for a same-day tooth replacement when an extraction is performed.
Our last consideration is positioning the implant so that the attached crown blends in naturally with the surrounding gum tissue and adjacent teeth. We must place it at the proper depth below the gum tissues so that the crown appears to emerge from them in the proper tooth length.
Taking extra care during all these phases, including the angle of crown attachment, will increase our chances of success. We still run a risk of implant damage or failure, however, from biting forces before the implant fully integrates with the bone. This means avoiding chewy foods and other situations that might increase the force on the implant. We may also use a temporary crown that’s slightly shorter than adjacent teeth so it won’t make full contact with the opposing tooth.
If you’d like to know if you’re a good candidate for a same-day tooth replacement, see us for a detailed examination. After reviewing your needs, we’ll be able to discuss with you the risks and benefits for a new look in one day.
