Implant Rejections Shoulder What Happens To The Bone Site Where Bone Is Taken For Bone Augmentation?

What happens to the bone site where bone is taken for bone augmentation? - implant rejections shoulder

I read here that if the necessary bone for dental implants is better for the patient's own bone to move - the chin or lower jaw, because there is no rejection. That will be the place where it was taken? makes it grow again happened to the original that is (for
Patients who are older)? Also how big it usually take for the sinus lift / increase in the upper jaw bone on both sides, and it is safe to do
dental surgery and the use of local anesthesia and generally
more complications? Thank you.
