An orthodontist assesses the growth and development of teeth and jaws and then determines the ideal time for treatment. Some patients require alignment of the jaws as well as the teeth. Appliances such as the Twin block and cross-bow appliance are used during adolescence to guide the growth of the upper and lower jaws. These appliances correct overbites and can provide optimal facial balance and aesthetics. There are also appliances such as the face-mask that can be used to treat or minimize under-bites.
