In orthodontics, good bracket placement is the key to optimum occlusionesthetics and efficiency. Indirect bonding is a method where brackets are placed onto casts from which a custom tray is fabricated capturing these bracket positions. An adhesive is then applied to the custom base of each bracket in the tray which is then seated in the mouth and a curing light is used to transfer these brackets to the teeth one arch at a time. Because the curing light must pass through the tray, a portion of the light will be absorbed or scattered by the tray and therefore has the potential to decrease the composite degree of conversion which could negatively affect the bond strength and treatment success.
