Abstract:
A device useful for delivering a predetermined treatment agent using a non-adhesive carrier for controlled regional release where the relationship between pore size, molecular weight, concentration and the like are predetermined to achieve specific predetermined time and quantity of release. The device includes a mouthguard shaped for extended contact with a substantial portion of the users mouth, such as all of the teeth and gums, for example, so as to provide treatment to a major region of the mouth as opposed to specific topical points of treatment. The mouthguard is held in position by properly fitting it to the patient, such as by softening and molding in situ. The portion of the mouthguard that is in direct contact with the region of treatment is formed from a polymeric material having a network of porous cavities that are sized to incorporate the treatment agent and release that agent over a predetermined period of time. The specific rate of release is controlled by balancing the molecular weight, molecule size, cavity dimensions, and specific properties of the carrying fluid, such as surface tension, solubility and viscosity. Specific preferred treating agents are sodium fluoride for cavity prevention and saliva control agents used during athletic sport participation.
