providing a positive tooth model comprising at least one mock bracket, the at least one mock bracket comprises a fully formed distal part of a bracket, and a place holder instead of a proximal part of a bracket, the place holder extending perpendicular from the horizontal median of the at least one mock bracket to the portion of the positive tooth model representing a gum; or providing a positive tooth model comprising at least one a place holder, the place holder extending perpendicular from a horizontal median of the position for placing a bracket at one tooth to the portion of the positive tooth model representing the gum, wherein the distal portion of said place holder or apron is formed as a negative model of the proximal portion of a bracket; and placing a bracket with its proximal portion into the distal portion of the at least one place holder or apron in a form-fitting manner; using said positive tooth model for preparing a transfer tray, said transfer tray comprising at least one cavity for accommodating a bracket, said at least one cavity being configured to accommodate the distal part of the bracket in form-fitting manner; fitting a bracket into the at least one cavity of the transfer tray; placing the transfer tray accommodating the at least one bracket onto teeth of a patient within the patient's mouth; filling the space between the at least one bracket and a tooth within the patient's mouth with a curable resin; curing the curable resin thereby binding the at least one bracket to the tooth; and removing the transfer tray from the patient's mouth. |
