When somebody asks me, "what is the most important thing in Orthodontic treatment?" from my -year clinical experience, I would say to stabilize the position of the lower jaw and to establish healthy left and right temporomandibular joints (TMJ).The appearance of the face is greatly influenced by the position of the lower jaw, the position of the teeth, and the placement of chin, so it is important to decide the treatment method well before starting treatment. Focusing on the face and TMJ, and aligning the teeth accordingly, this is the orthodontic treatment that our clinic aims for.
