This case is going to replace 4 anteriors. Implants are Straumann NC.
Pretty straight forward set-up, then fabricating a laser assembled Ti bar.
Bar post ( Titan) were placed on the cast needing to be cut to proper height as in the photos using the putty matrix as a guide. Once done, the bar post are connected using Ti bar sections laser welded together. The bar is blasted with aluminum oxide and opaque with Sebond light pink. Placed on the cast, using the putty matrix for a quick reset of the teeth. Also verified on the articulator as well. Case is waxed up, invested and processed using Ivocap injection. The bar is held using analogs, and the holes are filled with gingifast to prevent acrylic flowing into them. Where the holes are in the wax, I leave a slight indentation so I can easily locate and run a burr into it to clean out the gingifast. Leaves a nice clean hole. Minimal amount of finishing, polish and seat back on the master cast.
