Since the advent of Orthodontic copper, nickel and titanium wires 25 years ago, moving teeth got exponentially better. These wires offer light force over a long period of time - offering optimal teeth movement with less patient pain. In Orthodontics, moving the teeth slowly and consistently are key to allow the supporting bone and tissue to re-model, as the teeth move. Fast movement can cause shortening of teeth roots and negative changes to the supporting bone. Another benefit to these longer lasting wires: less frequent appointments for the patient.
A new technology offers even better results, by using lasers to treat these nickel titanium (NiTi) wires to offer different levels of force at different points along the wire. This enhances teeth movement because each tooth type requires different levels of force. The back teeth (molars) for instance, need much more force than the front teeth (incisors) to move. Normal NiTi wires give force throughout the wire length, but do not provide tooth-specific-tailored force amounts that align with what each tooth type needs. Often, molar teeth can be suborn in moving during treatment and often lag behind the incisors. This new wire provides just the right amount of force for each tooth type. The result: more efficient teeth movement, longer periods between Orthodontic visits and Orthodontic cases finishing sooner.
