Management of Class I Type 3 malocclusion using simple removable appliances

According to Dewey's modification of angle's malocclusion, Class I Type 3 malocclusion is the Class I malocclusion with anterior crossbite. This case report illustrates the treatment of the 13-year-old patient, with a crossbite of the maxillary right permanent central and lateral incisors. Two upper acrylic removable appliances, each with an expansion jackscrew, were used to correct the crossbite. The total active treatment time was 6 months, and the treatment outcome was successfully maintained for the subsequent 6 months. General and pediatric dentists, as well as orthodontists, may find this technique useful in managing crossbite cases of the permanent dentition by the removable appliance and utilizing the discussion and illustrations for further clinical guidance.
