You're correct, Orthosynetics is the newest incarnation that has emerged from OCA/OEC.
From what I understand, they've morphed into a practice management company, doing all of your practice and employee management while you do the ortho. Somewhat akin to Sun Orthodontix but in a different format. The difference is that they don't have their fingers in any residency programs like they did when they were the OEC, so the potential for the ruination of the profession isn't (currently) there.
