A dental implant can permanently restore the form and function of a missing natural tooth. But there’s an important prerequisite for this smile-transforming therapy — you must have enough bone remaining at the implant site to securely anchor the implant and ensure proper crown placement for the most natural looking result.
Patients who don’t meet this prerequisite may need to consider other restorative options. In some cases, however, we may be able to encourage sufficient bone growth to support an implantation through a technique called bone grafting.
Bone grafting involves opening the gum tissues at the intended implant site to expose the underlying bone. We then place the grafting material (usually a processed material) around the bone, sometimes with collagen membranes that serve as subterranean band-aids to guide bone growth. In most cases, the graft is actually a scaffold for the natural bone to grow upon; the natural bone will eventually replace the graft material. The procedure is normally performed with local anesthesia to minimize discomfort.
While bone grafting is a fairly routine procedure, it shouldn’t be undertaken unless there’s a firm prognosis it can successfully support a future implant. We must therefore determine if anything else in your oral health would disqualify you as an implant candidate, even if sufficient bone existed or not. We must also determine if there’s enough remaining bone currently at the site to even attach a bone graft.
Once we’re satisfied that bone grafting would be both possible and helpful, we must then consider what type of grafting material to use. If we’re only replacing one tooth we may choose to use an autograft, bone material taken from another area of your own body. Although autografts have advantages because of their regeneration ability, it does involve creating another surgical site within the body. In most cases we may use processed materials, for example allografts, material that originates from another human being; xenografts, taken from another species of animal; or synthetic (man-made) materials. Regardless of the source, these materials are first processed to be safe for human use.
If successful, the regeneration process will result in enough new bone structure to make dental implants a reality. Your mouth will be healthier — and your resulting smile will be more beautiful than ever.

Actor Michael Douglas shocked TV audiences across the country when he announced on the David Letterman Show in 2010 that he has stage IV oral cancer. Fortunately, the cancer had not spread and his radiation and chemotherapy treatments were successful. This year, Douglas teamed up with the Oral Cancer Foundation to warn others about the dangers of the disease and the importance of early detection. In particular, he wants younger people to know that even if they don't smoke and drink a lot, as he admitted to Letterman that he did, they are still at risk.
As Douglas states in a PSA he made with the foundation, “the fastest growing segment of the people developing oral cancers are young, non smokers.” That's due to a strain of the Human Papilloma Virus known as HPV16 that can be transmitted through oral sex. So it's important to avoid risky sexual behaviors and to be screened regularly for this devastating disease that claims one life every hour in the U.S., according to the Oral Cancer Foundation.
An oral cancer screening is a simple visual and tactile exam done right here at the dental office. We will feel your neck for lumps and inspect your lips and all inside surfaces of the mouth, including the back of your throat, for any suspicious signs. If any are found, a biopsy (laboratory analysis of a tissue sample) can be ordered.
Most oral cancers are “squamous” (small scale-shaped) cell carcinomas that occur in the lining of the mouth and are often preceded by recognizable changes (lesions) of the oral membranes. White or red patches begin to form in the pre-cancerous stage, and as the cancer develops, a non-healing ulcer may appear. If you notice any such changes in your mouth, please let us know.
Michael Douglas ends his PSA with the following plea: “So please, the next time you visit your dentist or your medical doctor, ask for this simple screening. Finding oral cancer in its earliest stages may save your life.” We agree, which is why we always perform this screening during your regular dental check-up. If it's been a while since your last appointment, please come in and see us.
