To rotate an abutment, take these steps:
1. Right-click the implant.
2. Select Abutment > Rotation from the Implant shortcut menu.
3. Press the up or down arrows of the rotation spinner to adjust the position of the abutment.
When working with an engaging abutment, the abutment will rotate in fixed increments, corresponding to the valid angles, depending on the implant connection. For a non-engaging abutment, the abutment rotates in steps of 1 (one) degree with respect to the implant.
