ASolutionforRestoringAdequateBoneforDentalImplants

Dental implants are considered the best tooth replacement option available. An implant replaces the root of a tooth and allows for the replacement of the crown via attachments or abutments. They not only look like a real tooth, they function like one too.

Implants, though, for some are a significant investment and may be well beyond a person's financial means if they've experienced a sudden tooth loss. For that reason, many opt for a less expensive tooth replacement option like a removable partial denture.

Later when they can afford it, a person might consider an implant. But this could pose a complication. When a tooth is missing for some time, the underlying bone doesn't rejuvenate normally because it no longer receives stimulation from the tooth. Over time, the amount of bone may diminish. Restorations like dentures can't stop this bone loss and actually aggravates it.

For proper positioning, an implant requires a certain amount of bone volume. So, it's quite possible when the time comes to replace the old restoration with an implant that there may not be enough bone available.

We may be able to overcome this bone loss with bone grafting and regeneration. A specialist such as a periodontist or oral surgeon accesses the area surgically and inserts bone graft material, usually processed material that's completely safe. Properly placed, the bone graft serves as a scaffold that, along with growth stimulators, encourages bone cells to grow.

When the bone grafting has healed enough, we're then able to place the implant. Once imbedded in the bone, one of the implant's unique qualities comes into play. The imbedded post is made of the metal titanium, which is not only bio-compatible with body tissues, it also has an affinity with bone. Bone cells will easily grow and adhere to the implant surface. This further boosts bone growth in the area and strengthens the implant's hold.

These extra procedures to build back lost bone do add to the cost and time for installing an implant. But if you're ready for a more permanent restoration for a missing tooth — not to mention better bone health — the extra time and money will be well worth it.

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.
