A method of indirect bonding used in orthodontic treatment includes the steps of placing a first component of an adhesive on base structure of an orthodontic appliance and a second component of the adhesive on portions of a patient's tooth. The appliance is connected to a transfer tray, and the transfer tray is placed over the tooth such that the first component and the second component contact each other and react to provide a bond for securing the appliance to the tooth. The bond has sufficient strength within two minutes and preferably within 1.5 minutes of the time that the first component contacts the second component to enable removal of the tray from the tooth without significantly changing the position of the appliance on the tooth.

[ We claim:] [1.] A method of indirect bonding an orthodontic appliance to a tooth comprising the steps of:creating a replica of a patient's tooth structure;releasably fixing at least one orthodontic appliance on the replica;making a transfer tray by placing matrix material over the replica as well as over each appliance;detaching the transfer tray with each appliance from the replica;placing a first component of an adhesive on base structure of each appliance;placing a second component of the adhesive on the patient's tooth structure; andplacing the transfer tray over the tooth structure such that the first component and the second component contact each other and react to provide a bond for securing each appliance to the tooth structure, wherein the adhesive has a set time of no greater than 60 seconds, and wherein the numeric average of the viscosity of the first component at 25.degree. C. and the viscosity of the second component at 25.degree. C. is greater than 30 poise using a shear rate of 10 sec.sup.-1.
