Orthodontic treatment for patients with congenitally missing mandibular second premolars can be challenging. Treatment options include keeping the deciduous second molar, extracting the molars and allowing the space to close spontaneously, autotransplantation, prosthetic replacement, and orthodontic space closure. Space closure with orthodontic appliances is demonstrated in this case report.
