Abstract
Buccal crossbite or scissors bite is a rare form of malocclusion which is very difficult to treat especially in adults. A 23-year-old woman had been referred due to scissors bite on the right side and bilateral mandibular first molar extraction space. Scissors bite with large vertical overlap from the first premolar to the second molar was observed on the right side. Large overjet, crowding, mild protrusion and mild asymmetry were also presented. By using multiple orthodontic mini-implants, intrusion of the maxillary and mandibular posterior teeth and uprighting of the mandibular posterior teeth were successfully obtained. The extraction spaces of the mandibular first molar were closed and the mandibular third molars showed good occlusion after debonding.
