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-produces general purpose orthodontic devices, which are not orthodontic devices that have been specially customized as to design, cut, etc. for individual patients.
