What is the first step in adding a mastoid bend?

• A. Heat the temple behind the bend
• B. Cool the temple
• C. Bend without heating
• D. Clamp and bend

Answer: (A)

When you add a mastoid bend, the first step is to soften the temple by applying heat to the area just behind where the bend will be. Heating makes the material pliable, allowing you to form the bend without cracking or distorting other parts of the frame. Heating behind the bend also helps protect the visible surface and ensures the bend takes evenly. Bending without heating is unlikely to hold the shape or could damage the frame, and simply cooling won’t enable the bend to form. After the temple softens, you would clamp and bend to the desired angle and let it set.
