Is he talking about adults or children?

Thank you Dr. Derek Mahony. I just have 1 question, in the example at 51:20 you say you will even use headgear even though it is a class II patient. What do you anchor the facemask onto to ensure good changes and at what angle for this patient specifically? I ask this because I have the exact same classification.
Thanks.

I’m 45 can I still do this

I'm pretty sure he said if mandible is the right length he can do it at any age. I emailed him to ask about it but he refered me to a local orthodontist. Asked Mike Mew (I live 30min away from him) and he is not taking old patients like me;) But he told me to go to the same orthodontist. So if you are interested I can let you know what I have found out soon.

@@boombox4321 Orthodontist recommended by Dr Mahony told me that it's not necessary to use mara and can do the job with elastics. I actually had a different Orthodontist do it with elastics and I swear my jaw moved forward but he says its only dental movement...🤔

I saw an Orthodontist that also uses Orthotropics on children, he advised I should get surgery. I'm too old at this point (25). If the one side of a stroke victims face can sag including, the mandible, maxilla, and teeth melting down, why can't this be recorrected with tongue posture. swallowing, using those masticatory muscles again which in turn pull on the bone to change the shape of the face?
You do enough digging through surgery is a short term solution to a lifestyle problem. Most good results are achieved from a class 3 malocclusion, whereas class 2 results aren't that impressive. They pull everything out, the angle of the mandible barely changes and if they don't correct the source of the problem, most people relapse. Removing teeth, nerve damage, surgery complications, is it worth it? Once the relapse happens and even post-op they're face is longer and still points down because the counter-clockwise rotation isn't achieved.
I've been thinking if one can achieve a counter-clockwise rotation of the maxilla that can substantially improve the occlusal plane, naturally the mandible should follow (take that with a grain of salt). Once this is achieved you can use MSE to expand the maxilla if necessary, in conjunction with a face mask for forward growth (I need to look further into it). Once you achieve this rotation then you can get Mandibular distraction osteogenesis in particular, IMDO. This can bring the mandible out ( even widen) slowly, allowing time for muscles and nerves to stretch gradually and it's less invasive compared to traditional orthognathic surgery. Achieve the rotation, increase the length and width of necessary bones where necessary, maintain it with proper tongue posture, breathing, swallowing, chewing etc. (This is necessary whether you have a properly developed face and jaw or not). We realise it's bone growth and formation that's the foundation of straight teeth and a good jaw. When an orthodontist is so fixated on moving teeth instead of bone I loose interest fast. I understand they're professionals, they're trained to move teeth and it makes sense.
