All implants osseointegrated and were clinically stable at the time of the 12-month follow-up. No fractures or radiographically detectable alterations of the welded framework were evident. Results: Ten males and 10 females, with an average age of 51.8 years (SD = 15.1 years N = 20), were consecutively treated with 153 immediately loaded implants. Mean marginal bone loss and radiographically detectable alteration of the welded framework were assessed using periapical radiographs immediately after surgery and at 6- and 12-month follow-up examinations. This framework was used as a support for the final restoration, which was fitted on the same day as implant placement.

Final abutments were connected to the implants and welded to a titanium bar using an intraoral welding unit. Methods: Twenty patients with edentulous maxillae received a fixed restoration supported by an intraoral welded titanium bar.

Background: The aim of this prospective study was to evaluate the concept of intraoral welding as a suitable technique for the placement of a final restoration for the edentulous maxilla on the same day as surgery.
