The invention relates to a syringe (1) for dosed dispensing of material, in particular of free-flowing and/or pasty dental material, comprising a sleeve (10) for accommodating material and a piston (15) which can be inserted into the sleeve (10) and which comprises a piston member (15'), a frictional engagement element (25) which abuts an inner wall (35) of the sleeve (10), and an elastic element (30) coupling the frictional engagement element (25) and the piston member (15'), wherein the sleeve (10) and the piston (15) inserted into the sleeve (10) define an inner sleeve chamber (70) for accommodating the material, wherein the elastic element (30) can be tensioned, on insertion of the piston (15) and/or of the piston member (15') into the sleeve (10), by means of a relative lag of the frictional engagement element (25) in relation to the piston member (15'), wherein by relaxing the elastic element (30) it is possible for the piston member (15') to be expelled at least partially from the sleeve (10) while the frictional engagement element (25) remains motionless, in order to increase the volume of the inner sleeve chamber (70). The invention also relates to a corresponding method, a piston (15) and a frictionally engaging elastic element (20).
