Abstract: This case report describes the successful orthodontic treatment of a patient with Class Ⅱ malocclusion characterized by crowding and protrusion. The treatment involved the extraction of four first molars. Anchorage was reinforced using a transpalatal arch and mini-implant to facilitate space closure, which resulted in the favorable outcome of mesial advancement of the third molars to replace the extraction spaces of the first molars.

Key words: molar protraction, mini-implant anchorage, first molar missing, space closure
