ABSTRACT:
An orthodontic appliance, such as a plate, has means defining at least one opening therein, the opening having a resilient and deformable inner surface portion, and an elongated wire-type member having at least one end which is removably insertable in the opening of the first member. The elongated member has an engaging means for resiliently deforming the inner surface portion of the opening for lockingly and non-rotatably engaging the elongated member in the opening. When the plate is of a relatively hard material, a sleeve of resilient, deformable material is used to define the opening for receiving the elongated member.
