A release substrate is releasably placed across a layer of adhesive that has been coated onto the base of an orthodontic appliance such as an orthodontic bracket. The release substrate enhances separation from the adhesive coated on the appliance such that the shape of the adhesive is essentially undisturbed and preferably substantially all of the adhesive remains on the base of the appliance when the substrate is detached from the adhesive. The release substrate is particularly suitable for use with adhesives that have a relatively low viscosity, adhesives that are more tacky and/or adhesives that have less cohesive strength than adhesives conventionally used with precoated orthodontic appliances.
