Abstract :Twenty-two implants were placed in four Taiwan patients to support immediate full-arch restorations (one mandible and three maxilla) with intact opposite dentition. Passive-fit metalreinforced frameworks were fabricated chairside by intraoral welding method, and all patients had definitive restorations on surgery day. All restorations were fabricated by screw-retained, implantlevel components with full occlusal loading on the first day. Patients were recalled seven days, one month, three months and six months, with the follow-up period being over nine months until April 2016. All implants were osseo-integrated, no infection was observed around the implants, and no fracture or cracking was found on the restorations. All patients were satisfied with the restorations.
