IONTOPHORETIC DEVICE AND A METHOD OF DELIVERY FOR DENTAL APPLICATIONS

摘要

An iontophoretic dental device that positions electrodes at buccal and lingual gingiva is described herein. The iontophoretic dental device includes an electrode locating member and electrodes that are attached to the electrode locating member. Further described herein is an iontophoretic dental system for simultaneously positioning electrodes at the buccal and lingual gingiva of a tooth on which dental work is performed. The system includes a coupler, lead wires and an iontophoretic dental device that further includes a clamp and electrodes. The electrodes are operatively attached to the clamp. Also described herein is a method of delivering a medicament to teeth or surrounding oral tissues including placing an iontophoretic dental device on buccal and lingual gingiva, the device including a clamp, and applying current to the electrodes.

主权项

1. An iontophoretic dental device that positions electrodes at buccal and lingual gingiva, comprising:
an electrode locating member having a U-shape, the electrode locating member having a first arm and a second arm extending from a central location, wherein the electrode locating member is arranged and configured to straddle a target tooth such that the central point is positioned over the target tooth with the first arm and the second arm each having a length that extends from the central location of the electrode locating member to the buccal and lingual gingiva, respectively; and first and second electrodes, the first electrode coupled to an end of the first arm and the second electrode coupled to an end of the second arm, wherein, in use, the electrodes are positioned on the buccal and lingual gingiva and are arranged and configured to drive a medicament through the buccal and lingual gingiva to a root of the target tooth.
