| 217 | Low-splash reducing implement for dental applications | US13986557 | 2013-05-14 | US09055989B2 | 2015-06-16 | Arthur Kitchings Weathers; T. Wilfred Pye |
| The invention is a low-splash dental fluid distribution implement with the ability to evenly wear down tooth decay, diseased tissue, or undesired dentin in oral applications with live patients. The directed multi-beams of pressurized fluid are a combined plurality of individual beams paired in such a manner that the reflected fluid bursts are inwardly directed against each other. This canceling effect prevents damage to the oral tissues of the patient's mouth by curtailing outward bound bursts of fluid arising from the initial directed impact. Also, the outer edges of the strike zone receive a comparable force as that which hits the center. | ||||||
