Customised Bluegrass appliance reminder therapy. Report of two cases.

BACKGROUND: Thumb sucking habits make up the majority of oral habits. While thumb sucking is considered normal during the first two years of life, if it is not controlled and persists beyond the preschool period it may cause deleterious effects on dentofacial structures. Reminder therapy using Bluegrass appliance has been proven successful to intercept thumb sucking habit. CASE REPORT: We present here two cases of thumb sucking habit in 7 and 10 year old children corrected by non- punitive reminder therapy using a customised Bluegrass appliance.
