This article describes the orthodontic treatment of a 14.5-year-old girl with severe bidentoalveolar protrusion. Specially designed sandblasted, large-grit, acid-etched (SLA) orthodontic microimplants (C-implants, Cimplant Co, Seoul, Korea) were placed in the alveolar bone in all 4 quadrants to provide anchorage for en-masse retraction without the help of banded or bonded molars. Successful retraction was achieved. The mandibular dentition was detailed by using conventional orthodontic appliances during the finishing stage. The osseointegration potential of these microimplants allows them to resist rotational force moments and control 3-dimensional movements of the anterior teeth during retraction. Facial esthetics improved for the patient, fullness of the upper and lower lips was reduced, and the interdental relationship was corrected. Biomechanical considerations, efficacy, and potential complications of the treatment technique are discussed.
