Implants will be immediately loaded using S-R abutments (Institut Straumann) with temporary restorations. An open-tray impression technique was used for provisional restoration. Provisional restorations were made digitally with polymethyl methacrylate (PMMA) (Telio CAD, Ivoclar Vivadent, Schaan, Lichtenstein). Plaster models with scan bodies were digitized with a laboratory scanner (3Shape E1, 3Shape, Copenhagen, Denmark). Final virtual design of provisional restoration was performed with 3D design software (exocad Matera 2.3, Exocad, Darmstadt, Germany). Drilling of PMMA blocks was performed in a 5-axis milling machine (Zenotec Select, Wieland, Pforzheim, Germany). After 6 weeks they will receive final prosthesis.

At the end of the 6-week healing period, definitive prosthetic restorations were delivered. In preparation for the definitive prosthesis, a final open-tray impression was taken with an individual tray and polyether material (Impregum Soft, 3M Espe, Seefeld, Germany). An analog ceramic layering technique was performed in the process of producing a porcelain fused to metal restoration (Shofu Vintage Halo Porcelain, Shofu Dental Corporation, Ratingen, Germany). The metal framework was made using cobalt chromium metal powder material (Starbond Easy Powder 45, Scheftner, Mainz, Germany) with additive manufacturing technologies (EOS, Krailling, Germany).
