The electric resistance welding technique (ERW) proved in the medium term to be a successful option in the rehabilitation of the edentulous mandible and maxilla with a fixed restoration delivered on the same day as implant placement, using both butt-joint and tapered connection implants.The aim was to evaluate the nine-year effectiveness of maxillary and mandibular full-arch immediately loaded prostheses fabricated using the intraoral welding technique (ERW).All patients received the same day of surgery a fixed, full-arch prosthesis supported by an intraorally welded titanium framework created directly in the mouth of the patient using a titanium bar and dedicated components. Lifetable analysis of implant survival, complications and any other adverse events were recorded at yearly follow-up for a period of nine years.The mean age of the patients at the time of surgery was 59 years (SD=11.1+ min- 44+ max- 80). 138 out of 162 (85.18%) implants placed in maxillary cases and 104 out of 124 (83.87%) implants placed in mandible cases completed the planned nine-year follow-up. At the nine-year control the accumulated mean marginal bone loss was respectively 1.43 mm (SD=0.71) for the implants placed in the maxilla (n=138) and 1.31 mm (SD=0.75) for the implants placed in the mandible (n=104). The fracture of the composite resin superstructure was the most common adverse event.After a nine-year follow-up period, the intraoral welding technique (ERW) proved to be a predictable technique for the restoration of the fully edentulous patient with a fixed and immediate long-term prosthesis.
