Abstract
A lock for orthodontic treatment comprises a holding member fixed to a molar band, and a spring wire having an end removably held by the holding member. The holding member is configured such that the end of the spring wire is held on the holding member by being moved axially along the holding member. One of the holding member and the spring wire has elasticity in a direction perpendicular to its axis. The holding member includes a first engagement portion for preventing the movement of the end of the spring wire in a mounting direction, and a second engagement portion for preventing the movement of the end of the spring wire in a removing direction. The spring wire includes a first locking portion for engaging with the first engagement portion of the holding member, and a second locking portion for engaging with the second engagement portion of the holding member.
