The orthodontic device-setting tool (1) is provided with: a fitting section (11) having a fitting surface, which covers and fits together with at least one of the incisal margin, the dental cusp, or the occlusal surface of a tooth； a foundation section (12), which has a back surface that adheres closely to the labial/buccal surface or the lingual surface of the tooth and has, on the surface opposite the back surface, a front face on which the orthodontic device (3) is mounted； and a connecting section (13) that connects the fitting section and the foundation section. The tool has a frame section (123), which protrudes from the front face of the foundation section and can fit together with the orthodontic device. Use of the orthodontic device-setting tool makes it possible to mount orthodontic devices such as corrective brackets without holding the patient for long periods of time and to mount the orthodontic devices accurately at the desired three-dimensional mounting positions for the orthodontic devices regardless of the skill level of the dentist practitioner. Moreover, the tool can even be used with mass-produced general purpose orthodontic devices, which are not orthodontic devices that have been specially customized as to design, cut, etc. for individual patients.La présente invention concerne un outil de mise en place (1) d'un dispositif orthodontique pourvu : d'une section d'adaptation (11) présentant une surface d'adaptation, qui recouvre et s'assemble à au moins un élément parmi le bord incisif, la cuspide dentaire ou la surface occlusale d'une dent ； d'une section de fondation (12), qui présente une surface arrière qui colle étroitement à la surface labiale/buccale ou à la surface linguale de la dent et présente, sur la surface opposée à la surface arrière, une face avant sur laquelle le dispositif orthodontique (3) est monté ； et d'une section de raccordement (13) qui raccorde la section d'adaptation et la section de fondation.
