Prefabricated Bar System for Immediate Loading in Edentulous Patients: A 5-Year Follow-Up Prospective Longitudinal Study

Figure 4

Passive seating and occlusal relationship of the removable prostheses were checked. Removable prostheses were released in correspondence with the expected bar volume. The contacts between the prostheses and the mucosal regions, which were not involved in the surgical procedures, were used as anatomical pre- and postsurgical landmarks to avoid variations in the occlusal relationships previously achieved. Four large openings were made according to planned cylinder emergence.
