Rejuvenation of maxillary implant bar retained hybrid fixed prosthesis: A novel technique (original) (raw)

Abstract

Experimental Groups • 1 st Clinical Visit: An impression was made which simultaneously recorded the edentulous maxilla and picked-up the maxillary hybrid prosthesis with the gold bar suprastructure in poly-vinyl-siloxane (PVS) material. The occlusion was registered on the old prosthesis (Fig. 3,4 & 5) • 1 st Laboratory Stage: A master cast was fabricated (Fig. 6) and articulated (Fig. 7) against mandibular cast using a bite registration (Fig. 3) made at the 1 st clinical visit. The acrylic veneer and teeth were removed from the metal suprastructure (Fig. 9) and a new wax up (Fig. 10) for the hybrid prosthesis was completed using an index (Fig. 8) on the original gold bar. • 2 nd Clinical Visit: Same day, a wax try-in of the prosthesis was performed and relationships confirmed. • 2 nd Laboratory Stage: The verified prosthesis was processed , finished and polished overnight in the laboratory . • 3 rd Clinical Visit: The refurbished prosthesis was fitted the next day (Fig. 12).
