20130122449Even impact reducing implement for dental applications - Fluid distributions implement to evenly wear down dental decay, diseased tissue, or undesired dentin in oral applications with live patients. The dentist has adjustable control over both the intensity and distribution field of a low-pressure sterile fluid, which may contain a pre-determined amount of reductive elements held in suspension. The implement must be supplied with a source of power and feed line of the chosen fluid. When switched on, it delivers one or a plurality of rapid bursts of varying impact strength in such a quick manner that the entire impact zone receives an even distribution of the liquid bursts. The desired result is the severe reduction in cratering, gouging, and non-symmetrical damage introduced by implements of the prior art such as drills, jet-stream fluid delivery systems, and tissue sanders with less danger of structural impairment to the patient in these cases of comparison.05-16-2013
20110008746APPARATUS OF LIQUID INJECTING FOR LIFTING MAXILLARY SINUS MUCOUS MEMBRANCE AND THE METHOD FOR THE SAME UTILIZING THIS APPARATUS - A liquid injection apparatus for lifting a maxillary sinus mucous membrane includes a passageway longitudinally extending through inside the apparatus; a connecting pipe formed at a rear portion to connect with a liquid supply apparatus; and an injection pipe 16 formed in a front portion, for being inserted into an implant hole extending to a bottom of a mucous membrane of a maxillary sinus, with a distal end of the injection pipe 16 spaced apart from the mucous membrane by a predetermined distance. The injection pipe is structured to inject liquid into the implant hole while closing the implant hole. The liquid injection apparatus can more easily lift the maxillary sinus mucous membrane without damaging the same by applying uniform pressure to the maxillary sinus mucous membrane when the maxillary sinus mucous membrane is being lifted.01-13-2011
