Patent ID: 6966773

Claim:
A tray fitted to at least some teeth of a patient's upper or lower arch for the application of medications to the teeth and to adjacent gum tissue for treatment of periodontal disease, said tray being of resilient elastomeric material molded to substantially conform to said teeth and gum tissue, said tray having at least one recess formed to conform to the teeth, a raised seal surrounding said recess corresponding to a location along the patient's gum line for applying along only the outer portion of the patient's gum line when the patient's teeth are disposed in the recess, said recess containing a quantity of a medication and a propulsion agent such that upon installation of said tray on the patient's teeth the medication is forced onto the surface of the teeth and subgingivally by the seal into any pockets in the patient's gums proximate said teeth, and the propulsion agent generates pressure within said recess so as to direct the medication onto the patient's teeth and into any of said pockets in the patient's gums proximate said teeth.
