Tetric Evoceream (Ivoclar Vivadent, Schaan, Liechtenstein). The tooth was then prepared with the diamond bur round end taper no. 8881-314-014 for an axial reduction of 0.8-1.0 mm, followed by a chamfer margin circumferentially and occlusal reduction of 1.0-1.5 mm with a round wheel no. 909:(Kappaomet, Brasseler, Lemgo, Germany) according to the recommended preparation guidelines of the manufacture of the hybrid ceramic block (Fig. 5).
