Example of the indirect method

Anterior trauma affecting teeth 23, 22, 21, and 11 (FDI) (ADA: 11, 10, 9, 8)

Standardized canal preparation with root canal burs*

Permanently incorporated ceramic build-ups with ComoPost. The preparation margin is located approx
2–3 mm below the build-up.

Situation after the incorporation of the all-ceramic crowns (IPS Empress).

Preparation for the impression using impression posts**

Pre-drilling with a root canal reamer (eg Gates-Glidden or Peeso from Brasseler)

* It must be noted that a 1.7-mm root bur was used for pre-drilling in tooth 23, 21 and 11(FDI)
(ADA: 11, 9, and 8), while a 1.4-mm root bur was used for tooth 22 (FDI) (ADA: 10).
