With Implants - Complete Arch Fixed Restoration Illustrated below is a patient who was wearing a complete upper denture but wanted to have a fixed ceramic bridge. After years of denture wearing and subsequent loss of bone, a three dimensional image was required to determine the feasibility of the treatment plan and to determine the amount of remaining bone and the ideal location of the implants. USE OF 3D IMAGING TO GUIDE THE PLACEMENT OF DENTAL IMPLANTS It is important that the amount and location of available bone is determined prior to the placement of dental implants. C.T. or Conebeam Imaging are used for this purpose. Implant location and the possible need for bone grafts are often determined by such diagnosie procedures. A C.T. image and a 3D model of the patient's jaw, show a lack of bone in the front of the mouth requiring either a graft procedure or for the placement of the implants farther back on the jaw.
