<p>An individual resin core (4) used for a bracket fitting method of an orthodontic appliance including an advance portion (41) packed between a base (31) of a bracket (3) and a tooth (11) and a core portion (42) extending from the advance portion (41) and covering a portion up to a cut edge (13) of the tooth (11) or an occlusal surface. The core (4) is individually formed for each tooth. Because this individual resin core (4) has low flexibility and is divided for each tooth, distortion and floating do not occur when it is fitted to the tooth of a patient, and the bracket (3) can be bonded correctly. Since the resin core (4) is independent of the alignment of teeth, it can be formed on a set-up tooth impression (1). Since the bracket (3) need not be returned to an original impression mold, technical work that would otherwise be necessary can be eliminated.</p> |
