Abstract: Facemasks using tooth-borne anchorages have been used primarily for the treatment of
Class III malocclusion with maxillary undergrowth. However, when using a tooth as an anchorage, if
the stability of the tooth used as an anchor is weak, the anchoring function may fail as the tooth tilts.
Meanwhile, the use of skeletal anchorages such as implants, mini-implants, and mini-plates has been
claimed to minimize the side eects of using dental anchorage. This case report describes the treatment
of a six-year-old male patient with Class III malocclusion, presenting maxillary undergrowth and
mandibular prognathism. Due to the mobility of the anchoring primary teeth, a device using dental
anchorage was replaced with that using customized skeletal anchorage for the treatment. Customized
guides and miniplates for the surgery were fabricated in advance through a computer-assisted system,
in order to avoid possible damage to the adjacent tooth buds. The customized plates were accurately
and passively placed on the intended part, showing the desired outcome.
