<p>A dental instrument for applying powdered polymers has a reservoir for the powdered polymer that is pressurized at least while the polymer is being applied and communicates with a polymer nozzle through a line for conveying the powdered polymer, which contains a polymer-blocking mechanism. A line for conveying liquid monomer connects a liquid-monomer container, which is also pressurized, with a liquid-monomer nozzle. The release of liquid monomer is controlled by another blocking mechanism. The nozzles are positioned at an interval while being aimed at the same operating area.</p> |
