Downswung and Downgrown: The Difference Matters

[thecel]

A downswung mandible is when the mandibular plane angle (MPA) is steeply downslanted and the difference between the MPA and the occlusal plane angle (OPA) is small. In other words, both the jawline and the occlusal plane are nearly equally downslanting. The lower jaw appears “swung” down.

A downgrown mandible is when the MPA is steeply downslanted and the OPA is pretty straight. The difference between the MPA and the OPA is big.

With a downswung mandible, bimax with counterclockwise rotation (CCW) has a strong potential to ascend.

With a downgrown-not-downswung mandible, there’s not much room for CCW. The amount of CCW that makes the MPA ideal is very un-ideal for the OPA; it’d make the occlusal plane angle upward-slanted, which looks really ugly and uncanny.

good thread but edit it & add pictures for the low iq people here

True, you would just give yourself SFS if you fucked up the occlusal plane

How can you fix a downgrown mandible? Is there no fix?

Good thread. I have a downgrown mandible what are some fixes?

gonial implants + chin height shaveoff

How a too-CCW-ly rotated occlusal plane loo

I might be retarded but what does a too CW rotated or ideal rotated occlusal plane look like then I’m jus looking at teeth and gums

Also Downswung looks way better ngl tall face vs soy face

Do u mean CWly?

 

[blahblahblahblahbla]

Thats literally my OP and im convinced it makes me uglier lol. I would be a giga mogger with a 6° steeper jaw

 

[LEFORT17]

gonial implants + chin height shaveoff

looks good

Basically you are higher ranking subhuman than others if there is a mismatch between your occlusal plane angle and your mandibular plane angle.

I was just wondering i wasnt really expecting much

Can I dm you for opinion on my surgeon’s plan for my trimax

 

[enlightful]

Also Downswung looks way better ngl tall face vs soy face

Nigga no it doesn't

Tall face=shit facial harmony and low fwhr

Fuck this site,I wanted to share a picture but it doesn't let me do it

 

[gigacumster3000]

you got this bro, good thread tbh! i think a lot of people here would find that really helpful and informative your bone structure looks pretty solid ngl, just gotta keep mewing consistently and youll see those improvements.
