Angulation of the counter bevel placed in cast restoration is determined by:: (A) Amount of indicated involvement for facial/lingual surface, (B) Measured by the embracing angle, (C) Amount of needed retention, (D) All of the above
Answer is D. Angulation of the Counter Bevel
Measured by the embracing angle: Angle between the bevel and the long axis of the crown - 30 to 70 degrees.
Factors Determining the Angulation
1. Amount of indicated involvement for the facial / lingual surface:

The more the desirable involvement is, the less will be the embracing angle to preserve tooth structure.

2. Amount of needed retention:

The shorter the preparation walls, the less will be the embracing angle with the long axis.
May be parallel to the intracoronal wall proper.

3. Type of cast alloy:

The less the castability, the greater will be the embracing angle.
Allows more bulk marginally.
