<p>A system for long term releasing of medication in the mouth, and especially an intra-oral fluoride releasing system (IFRS) for releasing fluoride over a long term for inhibiting the formation of caries in the teeth. The system uses a holder (10) for retaining and protecting intra-oral fluoride tablets (100) or other intra-oral medicament in the form of fluoride releasing devices (IFRD). The holder (10) has a plate (30) with retaining sides (40) and retaining posts (50) or a carrier. The tablet (100) will fit within the holder (10). The tablet (100) may be located in the carrier, or ligature bands (200) can be tied around the tablet (100) in order to releaseably hold the IFRD within the holder (10). The system causes a level of fluoride to be maintained over a long term within the mouth which has been found chemically effective for caries control and without causing severe irritation to oral tissues. In another embodiment, the user of an orthodontic bracket is provided with a system where a post (300) is attached to the orthodontic appliance (360) perhaps at the archwire slot, and the IFRD is placed within the mouth at a site removed from the orthodontic brackets (360) themselves. This unique combination provides for better oral hygiene and yet delivery of a fluoride to the mouth through the IFRD. <IMAGE></p> |
