Figure 4.

Two plastic models with the same deformity as in the model of Figure 2. In (A): cuts with obliquity of 65° were made in both models, but in opposite directions; this corrected the angular deformity. In (B), the two models after correction of the angular deformity are compared with an intact model (center). In the model on the left, in which the inclination of the cut was incorrect, correction of the angular deformity was possible, but the rotational error increased (lower left). On the other hand, in the model on the right, in which the obliquity of 65° was in the correct direction, the corrections of both the angular and the rotational deformity were perfect (lower right).
