A clinician should avoid extracting maxillary teeth in Class III cases to contain the forward growth of the mandible. This article presents a case report of a pseudo Class III patient with anterior crossbite and maxillary blocked out canines, based on the best available evidence. We hereby propose a combination of rapid maxillary expansion with 2 × 4 appliance to provide a predictable and effective approach to managing pseudo Class III treatment with blocked out canines (moderate crowding) that were once considered implausible. A clinician should avoid extracting maxillary teeth in Class III cases to contain the forward growth of the mandible.
