Abstract:
An orthodontic bracket with a positioning guide is produced by thinly coating a first dental photopolymerizable composition 1 on a bonding surface of each orthodontic bracket B, building a second dental photopolymerizable composition 2 adhesive to the first composition 1 on the bonding surface, adhering it to a tooth surface of a dentition gypsum model 3 reproducing a patient's dentition, a separating material being previously coated on the tooth surface of the gypsum model 3, polymerizing/curing the first and second compositions 1 and 2 by irradiating light, thinly coating a third dental photopolymerizable composition 4 on a tongue side and/or a cheek side entire surface around the orthodontic bracket B on the gypsum model 3, the third composition 4 being easily abraded when an occlusal pressure is acted, and polymerizing/curing the third composition 4 by irradiating light to be integrated with at least the second composition 2.
