Production method of orthodontic bracket with positioning guide

A production method of an orthodontic bracket with a positioning guide, which is bonded and fixed on a tongue side surface and/or a cheek side surface of each tooth of a patient, the production method comprising processes of:

• thinly coating a first dental photopolymerizable composition as a base material on a bonding surface of each orthodontic bracket mounted to an orthodontic wire, where the bonding surface is to be bonded to a tooth surface;
• building a second dental photopolymerizable composition having an adhesive property to said first dental photopolymerizable composition, on the bonding surface of the orthodontic bracket, in order to fill a gap which occurs between the tooth surface and the bonding surface of the orthodontic bracket at a time of bonding the orthodontic bracket to a tooth of the patient;
• adhering the bonding surface to a tooth surface of a dentition gypsum model reproducing a dentition of the patient, where a separating material is previously coated on the tooth surface of the dentition gypsum model;
• polymerizing/curing said first dental photopolymerizable composition and said second dental photopolymerizable composition by irradiating light;
• thinly coating a third dental photopolymerizable composition, which is easily abraded when a occlusal pressure is acted on a tongue side entire surface and/or a cheek side entire surface around the orthodontic bracket on the dentition gypsum model;
• and
• polymerizing/curing the third dental photopolymerizable composition by irradiating light so as to be integrated with at least the second dental photopolymerizable composition.
