What is the variety of facial profile in class II/1 malocclusion gnatic form?

• A. Convex profile
• B. Concave profile
• C. Rectilinear profile
• D. Slightly concave profile

Answer: (A)

In this skeletal pattern, the upper jaw tends to be relatively forward or the lower jaw is set back, which makes the side view of the face bow outward. The result is a forward-curving or convex soft-tissue silhouette from the forehead down to the chin. That forward projection of the maxilla (and/or retruded mandible) creates the pronounced convexity characteristic of Class II Division 1 gnathic form.

Concave or straight profiles are more typical of other skeletal patterns—for example, a concave profile often aligns with a Class III pattern where the mandible is prominent, and a straight profile suggests less pronounced anteroposterior discrepancy. Slight concavity is a milder form of these patterns and isn’t the usual presentation for this Class II/1 group.
