This young patient is almost 10 years old when she first came in for a consultation. Besides the crowding and misalignment of her upper front teeth, her upper jaw is narrow and in a crossbite. Expansion of her upper jaw was done with a Hyrax appliance which she wore for 6 months in conjunction with partial upper braces. Treatment time for Phase I was 12 months and she will need a Phase II treatment when all her permanent teeth comes in.
