The invention relates to a method for producing an attachment intended to form part of an orthodontic appliance and comprising a recess for receiving an orthodontic arch. During a first step, an attachment blank is produced, comprising an attachment portion of standardized configuration and dimensions and a base portion. During a second step, the base portion is shaped in order to provide the attachment with a customized configuration developed in accordance with the configuration of the tooth on which the attachment is to be placed and the desired position of the recess after the attachment has been secured to the tooth. Once it has been manufactured, the attachment has an attachment portion and a base. The invention also relates to the resulting attachment blank and attachment and to an orthodontic appliance including said attachment.
