Augmentation is an increase or extension of the jawbone and is needed by anyone in whom the dentist determines that the height of the tooth bone is not sufficient to place a dental implant in it. This usually happens when you lose a tooth for some reason, and over time, bone loss in that part of the jaw inevitably follows. The more time that passes between the extraction of the tooth and the installation of the implant, the greater the chances that you will need the installation of artificial bone.
