For the success of teeth implants, it is important to have the bone of the jaws to be strong and sufficient enough to give a holding to the implant. Due to periodontal diseases or by means of tooth erosion, sometimes there is very thin bone or brittle bone. This is a difficult situation for the surgeries to be performed. When dentists have such cases to handle, they usually go for bone regeneration as a first step in the reconstructive surgery.
In case of the back side upper tooth, there is the process of sinus augmentation, where the sinus floor is raised to provide enough bone for the tooth. Sometimes, bisposphonates are added to the area around the implants to regenerate bone in a natural manner. Bone regrafting is also a method used in some cases. In case of sinus augmentation, there is the need to regenerate the bones first, before the implant is proceeded with.
Ridge modification is another way of strengthening the jaw bones. These are required in cases of deformities in the upper and lower jaws, where ridges are uneven. Such deformities might be congenital, erosion or constant wearing of dentures or trauma. These defects are filled up with bone tissue or bone forming materials, which are helpful in regeneration of the bone in case of dental implants. In most procedures of dental implants, a considerable time is required for bone regeneration, to enable the prosthesis to fit properly.
