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.
Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Did you ever think a dentist might suggest that you have a bone graft performed as part of a standard tooth replacement procedure? Believe it or not, it's now a routine treatment — and it's not as complicated as you may think. Welcome to 21st Century dentistry!
If you're thinking about getting a tooth implant — an attractive, strong and long-lasting option for tooth replacement — here are four things you should know about bone grafting.
A bone graft may be needed prior to placing a dental implant.
One major reason why dental implants work so well as replacements for natural teeth is that they actually become fused to the underlying bone. This system offers superior durability, and a host of other advantages. Unfortunately, when a tooth is lost, the surrounding bone often begins to disappear (resorb) as well. In that case, it may be necessary to rebuild some of the bone structure before an implant can be placed effectively.
Bone regeneration for tooth implants is a routine procedure.
When it's needed, bone grafting has become a standard practice in periodontal and oral surgery. It is often performed prior to (or, occasionally, at the same time as) placing a dental implant. The grafting procedure itself can be done in the office, using local anesthesia (numbing shots, like those used for a filling) or conscious sedation (“twilight sleep”) to relieve anxiety.
The process may use a variety of high-tech materials.
The small amount of bone grafting material you need may come from a variety of sources, including human, animal or synthetic materials. Before it is used, all grafting material is processed to make it completely safe. In addition to the grafting material itself, special “guided bone regeneration” membranes and other biologically active substances may be used to promote and enhance healing.
Bone regeneration lets your body rebuild itself.
Your body uses most bone grafting materials as a scaffold or frame, over which it is able to grow its own new bone tissue. In time, the natural process of bone regeneration replaces the graft material with new bone. As we now know, maintaining sufficient bone tissue around the teeth is a crucial part of keeping up your oral health. That's why today when a tooth is going to be extracted (removed), often a bone graft will be placed at the time of extraction to preserve as much bone as possible.
