DISH Russian patent published in 2000 - IPC

FIELD: orthopedic stomatology, specifically, teeth prosthesis. SUBSTANCE: technical objective of invention is design of dish of simple and multipurpose structure made of dielectric material whose use ensures increased labor productivity and high quality of plaster mould and basic plastic of denture thanks to possibility of their drying and polymerization in SHF furnace. Both parts of dish, fixing latches, universal covers and four pairs of separable inserts of two type sizes are manufactured from construction dielectric plastic. Extruder incorporating cylinder, nut, screw rod and piston with lockpins is produced from metal if pressed into form of basic plastic or nut, screw rod, piston with lockpins and pusher are fabricated from construction dielectric plate if final extrusion of remainders of basic plastic from cylinder takes place. Diameter of smaller cylindrical stage of pusher equals diameter of outlet of cylinder and length of pusher is 0.5-1.0 mm longer than thickness of bottom of cylinder. EFFECT: design of simple and multipurpose dish ensuring increased labor productivity. 8 dwg
