Abstract
Dental care for a patient with maxillary protrusion and constriction of the upper dentition caused by oral habits was conducted for correction of the malocclusion as well as the oral habits, by using a removable biteplate with a lateral expansion screw. The patient used this appliance from 9 years-7months of age to the permanent dentition period. After using a retainer for I year-10 months, the treatment resulted in an esthetically and functionally established permanent occlusion, without any relapse of the oral habits.
