Which technique is used to set and expanded oval?

• A. Indirect
• B. Direct
• C. Diagonal
• D. Circumferential

Answer: (A)

Indirection in how pressure is applied is what makes this approach best for shaping an oval. When you use an indirect technique, you place contact and apply light, outward-reaching pressure that guides the edges of the oval to settle and gradually widen without forcing the center. This gentle, controlled method lets the tissue yield and the contour expand evenly, which is essential for a smooth, balanced oval.

Direct pressure, by contrast, pushes straight into the area you’re shaping and tends to compress or distort the outline rather than expand it, which is not ideal for achieving a natural oval. Diagonal or circumferential moves can create uneven results or follow paths that don’t align with the natural curves, whereas the indirect approach works with the tissue’s natural lines to set and enlarge the oval smoothly.
