ABSTRACT:
A human detention appliance or pacifier device or anti-thumb sucking device is made by a method of injection molding whereby a charge of fluoridating material is admixed with a high-temperature solvent, and then tumbled with a base thermoplastic molding material to form a pre-fluoridated mixture stable which is stable within the temperatures necessary to melt the mixture and the high-temperature limit of the high-temperature solvent, and physically embodied in the molding so that when used, the fluoridating material will leach out of the appliance and become mixed with fluids in the mouth at the buccal, labial, lingual and occlusal surfaces of the teeth which come in contact with the appliance.
