Is my maxilla downswung? (From ceph x-ray)

[Naris030]

SNA angle is 81 degrees(normal range). I have a gummy smile, and a narrow palate (30mm) due to tongue tie

So is my maxilla just downswung or is it downswung and recessed ?

And if so is there anything I can do at 18. Looking at biobloc, can that cause facial upswing?

Not even a question.

@Allornothing , what are the signs of downwards growth you can see? Because it looks like my occlusal plane is at 0 degrees.

It’s not about occlusal plane. It’s about antegonial notch, tilted out philtrum, downturned lips, high gonial angle.

Thanks for the knowledgeable response. Since all of the signs of my downward growth are on my lower third/LeFort 1 area, can my type of downwards growth and recession be fixed with a bimax?

I don’t think antegonial notch is from down growth

Yeah you’re right actually my bad. Antegonial notch is its own thing where the maxilla isn’t necessarily downgrown, but the mandible and chin (uniquely in this case) are.

Plenty of downgrown men have no antegonial notch. There’s 2 different types of downgrowth.

I thought it’s from massetar

It’s either due to downgrowth far along down the mandible, or it’s closer to the gonion due to angularity at the gonion from extra bone deposition at the bottom. There’s 2 types. The second type is masc and aesthetic. The first isn’t.

Could u show examples

First type.

Second type.

Notice how for the good type, it’s the gonion dips, not the second half of the mandible.
