This case report describes a method to produce one final master cast for the simultaneous prosthetic treatment of implants and natural teeth in a single arch. After tooth preparation, a first impression was used to fabricate electroformed crown frameworks. In the next appointment, the crown frameworks were seated and collected with the implant transfer copings in a single-phase fixation impression, which was used to fabricate a final master cast. This procedure divides the treatment process into distinct steps, leading to a faster and less challenging workflow.
