Le rail d'alignement orthodontique (SCU; SCU'; SCU"; SCO; SCU1; SC01; SCU2; SC02) présente la forme d'une coque qui présente, du côté intérieur, une cavité (KU; KO) pour recevoir une pluralité de dents d'une rangée de dents d'une mâchoire et, du côté extérieur, une surface supérieure (OSU; OSO), une surface latérale intérieure (ISU; ISO) et une surface latérale extérieure (ASU; ASO). Du côté extérieur, il est disposé au moins un élément de codage d'orientation (S1, S2, S3; S4, L1, C4; S5, S6; L5, L6; S1a, S1b, S2'C1, C2, C3; P1, P2, P3) pour coder un décalage orthognatique.
