GAP Australasian Dentist Mar Apr 2020

Category 80 Austràlàsiàn Dentist ZERAMEX®XT All on 8 – Fixed Md Prosthesis àlàn al Courtesy Dr. Michael Leistner à he 64-year-old patient presented in the practice for the new restoration of the lower jaw. àhe remaining teeth in the lower jaw were no longer suitable for a prosthetic solution. àhe roots of the teeth were only a few millimeters in the bone, all teeth were mobile (degrees of mobility from à to ). Dr. àeistner proposed a hybrid on four Zeramex Xà implants and locators, or a fixed prosthesis on eight Zeramex Xà implants. After this discussion, the patient did not come back for two years. àhe then came back with big problems. Another colleague had incorporated a ten units bridge construction on four of the previously existing seven teeth. àhe entire bridge was mobile and the patient was unable to eat solid food without causing severe pain. At that point the patient had already decided to go for a fixed restoration on eight implants, as per the initial recommendation, two years earlier. àhe fact that it was possible to use a 100% metal-free solution was also very appealing.
