Dental implants are a popular and effective restoration for lost teeth, if there’s enough bone present to support the implant. That might not be the case, however, because without the stimulation of the lost tooth, the bone may dissolve (resorb) over time. It’s possible, however, that you may need to re-grow bone in the back area of the upper jaw where your upper (maxillary) sinus is located.
Sinuses are air space cavities located throughout the skull. This feature allows your head to be light enough to be supported by your neck muscles. Inside each sinus is a membrane that lines your sinus cavities, nasal passages and other spaces. The maxillary sinus is located on each side of the face just below the eyes. Pyramidal in shape, the floor of the pyramid lies just above the upper back teeth.
A surgeon approaches the sinus through the mouth, with the objective of moving the sinus membrane up from the floor of the sinus. This is accomplished by placing bone-grafting material in the area. Over time the body uses the grafting material as a scaffold to produce new bone that then replaces the grafting material. The resulting new bone becomes the support for the implant.
If enough bone exists to stabilize an implant but not anchor it, then the surgeon can approach the sinus from the same opening that’s used for the intended implant site, insert the grafting material, and install the implant during the same procedure. If not, the surgeon creates a small “window” laterally over the teeth to access the sinus and insert the graft. The implant is installed a few months later after the new bone is created.
The procedure usually requires only a local anesthetic, although some patients may require additional sedation or anti-anxiety medication. After the surgery, you normally experience mild to moderate swelling and discomfort, about the same as having a tooth removed. All these symptoms can be managed with non-steroidal, anti-inflammatory pain medication and a decongestant for minor congestion in the sinus. We might also prescribe an antibiotic to help prevent infection.
Although this procedure adds another step and possibly more waiting time to implantation, it gives you an option you wouldn’t otherwise have — a life-like, effective replacement of your back teeth with dental implants.

Perhaps you've heard about dental implant surgery — or maybe you've been told you are a candidate for the procedure. You may already know that today, implants are the “gold standard” of tooth replacement options. It's no wonder why: They have a documented success rate of over 95%, and can last a lifetime. But if you're put off by the thought of implant surgery, then it may be reassuring to learn the following five facts.
1. The entire implant process is planned before surgery is done.
This usually involves taking radiographs (X-rays), and sometimes CT scans, as precision guides to implant placement. Before the minor surgical procedure begins, we have already examined the bite and the bone structure, and determined exactly where the implant will fit in. There should be no surprises during the surgery — which is only one phase of the implant process.
2. Implant surgery uses the highest-quality materials and state-of-the-art techniques.
The implant itself is fabricated of commercially pure titanium, or a titanium alloy. This metal has a unique property — it's capable of osseo-integration, which means it can actually fuse with bone. During the implant procedure, the bone is handled with utmost care: it's gently prepared to receive the implant, and cooled with water to prevent tissue damage. If you don't have enough of your own bone tissue to support an implant, it has even become routine to restore bone with grafting techniques.
3. The surgical procedure itself is generally painless.
Almost all implants are placed using local anesthesia — typically, a numbing shot. If you're especially anxious about the procedure, it's possible to be given sedatives or anti-anxiety medications beforehand. Of course, we will make sure you don't feel any pain before we begin! Some mild vibration is generally all that you may experience during the procedure, but it's very rarely a cause for concern.
4. There is little discomfort following the procedure.
On the day of surgery and perhaps the day after, a non-steroidal anti-inflammatory medication (NSAID) of the aspirin or ibuprofen family is usually all that's needed to control minor discomfort. You may also be given a prescription for antibiotics and/or a mouth rinse to aid healing.
5. The result: Natural-looking teeth that can last a lifetime.
Implants have become dentistry's premier option for replacing missing teeth. Their placement involves minimally-invasive techniques, and has a success rate higher than any other tooth replacement system. And, given proper care, they can last for the rest of your life. Could you ask for more?

You've probably heard about dental implants — today's best option for replacing missing teeth; maybe you even have one or more already. A dental implant is a tiny screw-shaped metal post that sits in your jawbone and supports a lifelike dental crown. Natural teeth and implant-supported teeth have differences and similarities.
The main difference between implants and natural teeth — besides the fact that you were born with one and not the other — is the way they attach to your bone. Implants actually fuse to the bone, becoming part of it. This is a unique property of titanium, the metal from which implants are made. Maintaining that attachment is extremely important; we will discuss how best to ensure that in a moment.
Natural teeth do not ever become part of the bone that surrounds them. Instead, they attach to it via the periodontal ligament (“peri” – around; “odont” – tooth), which is made up of tiny fibers that go into the tooth on one side and the bone on the other. These fibers form a sort of hammock for each tooth.
Another difference is that natural teeth can decay while implant-supported teeth can't. But that doesn't mean you don't have to worry about dental hygiene — far from it! And here's where we get to the main similarity: oral hygiene is extremely important to maintain both teeth and implants. Lax oral hygiene for either can result in bacterial infections that may lead to gum disease, and even bone loss.
The main enemy of a properly fused implant is a bacterial infection known as “peri-implantitis” (“peri” – around; implant “itis” – inflammation), which starts when bacterial biofilm (plaque) is allowed to build up on implant-supported crowns. Peri-implantitis can lead to a well-like or dish-shaped loss of bone around the implant, which in turn can cause the implant to lose its attachment to the bone. If this happens, the implant can no longer function. Fortunately, this infection is preventable with good brushing and flossing techniques at home, and regular professional cleanings here at the dental office.
So another similarity, then, is that natural teeth and implants can last a lifetime with proper care. And that's the result we're aiming for!
If you are one of the millions of Americans with missing teeth, then you're probably aware of some of the obvious side effects. You may feel self-conscious during conversations or simply avoid smiling altogether to conceal your dental issue. It is not uncommon for missing teeth to affect your confidence, but did you know that there are other problems that result from tooth loss?
For starters, if you have lost enough teeth, eating may become more difficult, in particular healthy foods, such as fruits and vegetables. This is one of the main reasons that inadequate dental care frequently results in nutritional deficiency.
Another very serious issue that results from missing teeth is bone loss. We sometimes refer to this as a “hidden consequence,” because you may not actually see or feel this issue right away. Did you know that bone is actually living tissue that needs constant stimulation to maintain its form and density? Thus, when a tooth is lost, the bone in the jaw that surrounded and supported that tooth melts away. There is a 25% decrease in width of bone during the first year after tooth loss and an overall 4 millimeters decrease in height over the next few years. The longer you have missing teeth, the greater the loss of bone.
As bone loss continues, it can actually affect the structure of your face. If you lose your teeth early in adulthood, by age 45 you might start to notice sunken cheeks. By age 60, your cheeks and lips will lose their support, resulting in a collapsed and aged look. If your teeth are not replaced, this process will continue, and you will be in danger of losing much of the structural support of your lips and cheeks.
Luckily, we can use dental implants to not only restore your smile, but also to halt this bone loss. Implants look, feel and function like your natural teeth and are made of titanium, which has the unique ability to fuse with your living bone. Among the many benefits of implants, they continue to provide stimulation to your bone, preventing further bone loss.
With a success rate of more than 95%, implants are the best long-term solution for tooth replacement.

Dental implantation is the premier option for tooth replacement available today. While acquiring dental implants does involve a surgical procedure, don’t let that deter you — with proper preparation the procedure is relatively minor and routine.
Implants are root replacements inserted directly into the jawbone to which a life-like, artificial crown is secured (strategically placed implants can also support fixed bridges or removable dentures). They’re typically made of titanium, which is osseophilic or “bone-loving”: bone will grow and adhere to the implant over a few weeks time.
Pre-planning can help minimize discomfort during and after the implantation procedure. We first conduct a radiographic examination of the site with x-rays or CT imaging; this enables us to assess the site’s bone quality and quantity. We can also create a surgical guide from the imaging to pinpoint the precise location for an implant to ensure a successful outcome.
Before beginning the procedure, we numb the area with a local anesthesia (we can also administer a sedative or other relaxation medication if you’re experiencing mild apprehension). The procedure often begins by creating a flap opening in the gum tissue with a few small incisions to access the bone. Using the surgical guide, we then begin a drilling sequence into the bone that progressively increases the size of the hole until it precisely matches the size and shape of the implant.
When the site preparation is complete, we remove the implant from its sterile packaging (which minimizes the chance of infection) and immediately insert it into the prepared site. We verify proper positioning with more x-rays and then suture the flap opening of the gum tissue back into place.
Thanks to both the pre-planning and care taken during surgery, you should only experience minimal discomfort. While narcotic pain relievers like codeine or hydrocodone may be prescribed, most often non-steroidal anti-inflammatory drugs like aspirin or ibuprofen are all that’s needed. We may also prescribe an anti-bacterial mouthrinse (with chlorhexidine) to assist healing.
In just a few weeks your custom-made restorations will be attached to the implants. It’s the completion of a long but not difficult journey; the resulting smile transformation, though, can last for many years to come.
