A SIMPLE PRACTICAL APPROACH TO IMPLANT REPLACEMENT  OF  UPPER ANTERIORS SANS BONE GRAFTS  IN SPITE OF A NARROW RIDGE P2513 WERE USED. P STANDS FOR PROSTHODONTIC HEAD.  25 IS THE DIAMETER IN mm. 13 IS THE THREADED LENGTH OF  THE IMPLANT IN mm.  THE UNIVERSAL DESIGN OF THE  PROSTHODONTIC HEAD ALLOWS IT TO BE USED IN ALMOST  ALL CASES. THE PRINCIPLE OF ACCURATE PLACEMENT AKA  PROSTHODONTIC DRIVEN PLACEMENT OF THE IMPLANTS  MUST BE ASSIDOUSLY FOLLOWED. AN ALGINATE IMPRESSION IS TAKEN AND THE RESULTING  MODEL SENT TO THE LAB FOR THE FINAL PFM BRIDGE. THE EXISTING ACRYLIC PARTIAL TEETH ARE REMOVED FROM  THE PLATE AND TEMPORARY CROWN AND BRIDGE ACRYLIC IS  USED TO FASHION THE TEMPORARY BRIDGE IN THE MOUTH AND  CEMENTED AWAITING THE PERMANENT.
