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.

Martha Stewart has built a flourishing career by showcasing the things she’s designed and made — like floral arrangements, crafts, and even home renovations. Just recently, she was showing off her latest restoration project: a new dental bridge. In fact, she live-tweeted the procedure from her dentist’s office… and she even included pictures of the bridgework before it was placed on her teeth!
OK, it’s a departure from paper crafts and home-made pillows… but why not? We can’t help feeling that there’s just as much craftsmanship — even artistry — in dental bridgework as there is in many other custom-made items. If you learn a little more about what goes into making and placing bridgework, perhaps you’ll understand why we feel that way.
Bridgework is one good solution to the problem of missing teeth (another is dental implants). A fixed bridge is anchored to existing teeth on either side of the gap left by missing teeth, and it uses those healthy teeth to support one or more lifelike replacement teeth. How does it work?
Fabricated as a single unit, the bridge consists of one or more crowns (caps) on either end that will be bonded or cemented to the existing teeth, plus a number of prosthetic teeth in the middle. The solid attachment of the crowns to the healthy teeth keeps the bridge in place; they support the artificial teeth in between, and let them function properly in the bite.
Here’s where some of the artistry comes in: Every piece of bridgework is custom-made for each individual patient. It matches not only their dental anatomy, but also the shape and shade of their natural teeth. Most bridges are made in dental laboratories from models of an individual’s teeth — but some dental offices have their own mini-labs, capable of fabricating quality bridgework quickly and accurately. No matter where they are made, lifelike and perfect-fitting bridges reflect the craftsmanship of skilled lab technicians using high-tech equipment.
Once it is made, bridgework must be properly placed on your teeth. That’s another job that requires a combination of art and science — and it’s one we’re experts at. From creating accurate models of your mouth to making sure the new bridge works well with your bite, we take pride in the work we do… and it shows in your smile.
