A method for fabricating a removable orthodontic appliance with lingual springs using a model of a patient's teeth. One or more ideal reference grooves (e.g., a central ideal reference groove, occlusal ideal reference groove, or gingival ideal reference groove) are cut into the lingual surfaces of the model teeth reflecting the desired, ideal positions of these teeth after orthodontic treatment. The orthodontic appliance is then cast on the model with the stem of each lingual spring stem embedded in the appliance and the tooth-contacting end of each lingual spring positioned in the reference groove of a model tooth.
