What causes the ramus to be lower than the mandible

[Mealworm]

I have this thing where my ramus is lower than my mandible, so it looks like I have an antegonial notch, but I don't

You have an antegonial notch, that's what it's called when the ramus surpasses the mandible body lol

The antegonial notch is a dip in the jaw, but mine's straight. But my ramus kind of cuts under the jaw.

The antegonial notch is caused by bone growth around the ramus and it's genetic

13 Hovell14 in 1964 stated that “when the condylar growth fails to contribute to the lowering of the mandible, the masseter and the medial pterygoid, by continued growth, cause the bone in the region of the angle to grow downward producing antegonial notching.”
