Molare controlaterale
Osservando il moto cinematico mandibolare a livello del molare lediotrusivo possiamo notare come cambia sia la direzione ( angolo rispetto all'asse perpendicolare che interseca il punto 1 del condilo mediotrusivo ma anche la medializzazione nel ritorno allo stato iniziale che sostanzialmente corrisponde allo svincolo mediotrusivo tra la cuspide centrale e distale del primo molare.
