IncreaseBoneMassforDentalImplantsthroughGrafting

Losing a tooth from disease or accident can be traumatic. The good news, though, is that it can be replaced with a life-like replica that restores your smile. One of the most popular and durable solutions is a dental implant, which replaces not only the root of the tooth but the crown as well.

But there's a possible wrinkle with implants — for accurate placement there must be a sufficient amount of bone around it. This could be a problem if you've been missing the tooth for sometime: without the stimulus provided by a tooth as you chew, older bone cells aren't replaced at an adequate rate. The bone volume gradually diminishes, as up to 25% of its normal width can be lost during the first year after tooth loss. A traumatic injury can damage underlying bone to an even greater extent.

There is a possible solution, but it will require the services of other specialists, particularly a periodontist trained in gum and bone structure. The first step is a complete examination of the mouth to gauge the true extent of any bone loss. While x-rays play a crucial role, a CT scan in particular provides a three-dimensional view of the jaw and more detail on any bone loss.

With a more accurate bone loss picture, we can then set about actually creating new bone through grafting procedures. One such technique is called a ridge augmentation: after opening the gum tissues, we place the bone graft within a barrier membrane to protect it. Over time the bone will grow replacing both the grafting material and membrane structure.

Once we have enough regenerated bone, we can then perform dental implant surgery. There are two options: a “one-stage” procedure in which a temporary crown is placed on the implant immediately after surgery; or a “two-stage” in which we place the gum tissue over the implant to protect it as it heals and bone grows and attaches to it. In cases of pre-surgical bone grafting, it's usually best to go with the two-stage procedure for maximum protection while the bone strengthens around it.

Necessary preparation of the bone for a future dental implant takes time. But the extra effort will pay off with a new smile you'll be proud to display.

RegeneratingLostBoneCanMakeDentalImplantsaReality

Every day the forces you generate when you bite or chew can exert enormous pressure on your teeth. And day after day your teeth remain stable and secure, thanks to an intricate system of periodontal ligaments, attaching gum tissue and bone. The latter element is especially important — healthy bone makes healthy teeth.

And vice-versa — the same biting forces are transmitted through the tooth root to the bone via the periodontal ligament to stimulate new bone growth to replace older bone that has dissolved (resorbed). If a tooth’s missing, however, the bone doesn’t receive that stimulation, and the resorbed bone isn’t replaced at a healthy rate. In fact, you can lose up to a quarter of bone width in the first year alone after tooth loss.

And this can cause a problem when you’re looking to replace that missing tooth with what’s considered the best restorative option available: dental implants. Known for their life-likeness and durability, implants nonetheless need sufficient bone to anchor properly for the best outcome. Without it, implants simply aren’t practical.

But that doesn’t have to be the end of the story: it’s quite possible to regenerate enough bone to support implants through bone grafting. Bone material from the patient (or another donor, human, animal or synthetic) is placed under the gum at the missing tooth site to serve as a scaffold for new growth. The new bone growth will eventually replace the graft material.

The size of the graft and extent of the procedure depends of course on the amount of bone loss at the site. Loss can be kept to a minimum, though, if the graft is placed immediately after a tooth extraction, a common practice now. After a few months, the bone created through the graft is sufficient for supporting an implant and gives you the best chance for a beautiful outcome.

If you’re considering an implant for a missing tooth, you should schedule a consultation appointment with us as soon as possible. After a thorough dental exam, we’ll be able to tell you if bone grafting to support implants is a good idea for you. It adds a little more time to the overall implant process, but the results — a new, more attractive smile — will be well worth it.

FourFactsaboutBoneGraftingforDentalImplants

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.

Are you considering dental implants for tooth replacement, and wondering whether you may need bone grafting? Come in and talk to us! With our up-to-date training and clinical experience, we can answer your questions, and present the treatment options that are best in your individual situation.
