Bone Augmentation and Bone Transplantation
Before the dental implant application, the bone to be implanted should have sufficient height and sufficient volume. However, after traumatic tooth extraction, if the patient has been toothless for many years, there may not be enough bone for implant application. Whether or not enough bone tissue is available is measured by measuring the panoramic x-ray with a special software program on the computer. In dental volumetric tomography (3D), bone dimensions can be measured by performing three-dimensional measurements. When the physician detects inadequate bone measurement before the implant application, bone formation methods are applied.
Bone graft using bone powder
Bone augmentation is the most common procedure in regional implant applications (with a few missing teeth). Often animal or synthetic bone powders are used. It may also be possible to placement an implant at the same time as the bone powder is used. Bone powder can sometimes be taken from the patient’s mouth without creating a wound (receiving site). This bone is one’s own bone, called autogenous bone. Autogenous bone is much safer and its success is much higher than artificial bone powders. The physician always wants to obtain bone with autogenous bone, but if this is impossible, artificial bone powders are used.
Block Bone Transplantation
In some cases bone grafting is not enough to create suitable bone volume. We should take bone from mandibula or from hip (on a very few occasion) and transplant to the insuffient bone for implant. If an operation is to be performed at this point, it is necessary to wait for bone formation for at least six months before implantation. After implantation, when three month waiting period is added a waiting period of approximately nine months should be happen. However, the most important factor to be success of dental implants in the mouth is that they have a healthy bone around the implant.
