Mod 1, case 1

[Chad Carter (Course Director)]

Shadi,

I have not thought about applying growth parsed at that level to the rotation of the occlusal plane. I don’t know that I could look at the condyle, maxilla and all four teeth traced on this ceph and come up with an occlusal plane movement answer with out looking at the traced occlusal plane itself.

With condyle tracing and then natural jaw position there is always the nature of the joint. For example I “unlock” a Class II Div 2 occlusion and all of a sudden it looks like their jaw grew but they actually postured relaxed with the disc in place.

Sorry I’m not much help there…

Thoughts from anyone else?

Sorry if I confused you! This is for Module #2 case #1 ( not module 1).

Got it! So for Module 2 Case 2 it looks like in the superimpositon that the change in occlusal plane is all due to the incisors. I’m looking at the intrusion and proclination of the maxillary incisors and then looks like straight proclination of the lower incisors. So whatever mechanics were in place were focused on leveling and maximizing the AP movement – exceptional vertical control of the molars too.

It’s like Orthodontics CSI looking at these sometime.

Hi! Just a follow up on this superimposition…I know md molars move forward due to growth about .5mm/yr – in this example, wouldn’t it be correct to include the Md molars in #4 of the answer? and say AP movement of md molars due to growth & tx effect or more AP movement of md molars due to tx effect? Thanks!

Pegah,

Good eye! You are correct. It’s on the list to update that response as well. I see the mandibular molars on Mod 2 Case 1 with prompt #10 have moved forward in the AP due to growth and treatment.
