Immediate Loading of Maxillary One-Piece Screw Implants Utilizing Intraoral Welding: A Case Report

Figure 1 . Schematic drawing of Mondani intraoral solder unit. Figure 2. Two blade and 8 screw implants inserted in the lower jaw of a patient. Figure 3. The 10 implants have been welded intraorally to a titanium bar by an electric current. Figure 4. Panoramic radiograph of 67-year-old Caucasian female patient. Figure 5. Intraoral photograph of patient before treatment. Figure 6. A panoramic radiograph confirms the deep bicortical placement of the implants. Figure 7. Immediate splinting is performed with a titanium supporting bar of 1.5-mm diameter set on the mucosa without any compression and welded to each implant with intraoral solder. The supporting bar must be placed so that the emerging abutments of the implants are free in the oral cavity. Figure 8. Intraoral view of provisional resin prosthesis cemented to the implants (immediate load). Figure 9. Panoramic radiograph taken 90 days after insertion of the provisional prosthesis.

Figure 12. Oral hygiene procedures are demonstrated to the patient. Figure 13. Thirteen-year follow-up radiograph shows preservation of bone surrounding all of the implants. Figure 14. Thirteen-year follow-up intraoral photograph shows healthy appearance of the oral mucosa.
