1. An assembly for a bone expansion, comprising:
a bone expansion apparatus, wherein the bone expansion apparatus is a distraction plate apparatus;
an activation tool for the bone expansion apparatus, wherein the activation tool includes a magnetic element solidly attached to a rotation shaft of the activation tool, the magnetic element being configured to interact coaxially with a remote magnetic element borne by the bone expansion apparatus, the activation tool further including an electric motor configured to cause the rotation shaft to rotate, and a control module controlling the rotation of the rotation shaft; and
a device to assist positioning of the magnetic element of the activation tool with respect to the magnetic element borne by the bone expansion apparatus,
wherein the device to assist positioning of the magnetic element of the activation tool includes a sheet of formable or thermoformable material configured to be attached to a subject and including a guide for positioning the magnetic element, wherein the formable or thermoformable material is a rigid material and is of a first shape and configured to be further shaped or modelled by a shaping operation to obtain a second shape which will be retained thereof unless further shaping operation is performed.
