Abstract
A useful method of handling orthognathic treatment models is
described that utilises magnetic attachment of study models to
an articulator, allowing rapid and reliable manipulation between
pre- and post-operative positions of the maxilla and/or
mandible. Both the orthodontic and surgical staff can easily
study planned surgical movements.
