发明名称 Bonding base and method of making the same for a plastic orthodontic bracket
摘要 A bonding base and method of making the base for a plastic orthodontic bracket to provide a mechanical lock that inhibits both shear and tensile forces when bonded to a tooth with a mechanical bonding adhesive. The bonding base includes a coating or layer of thermoset epoxy, urethane or acrylate chemistry having partially embedded therein a layer of textured particles that define multi-directional undercuts and projections. The method of making the bonding base includes the steps of applying a substantially uniform in thickness coating of the chosen chemistry to the tooth-attaching side of the bracket, next applying a layer of textured particles to the coating while it is wet, and then curing the coating to lock the textured particles to the bracket for producing a textured mechanical lock.
