Abstract: A method for producing blanks for endodontic instruments (1), endodontic instruments (1), and a delivery device. The method comprises the steps of providing at least one rod (2) and machining the at least one rod (2) by a wire erosion such that an erosion pattern (4) is applied to the at least one rod (2). The material eroded away from the at least one rod (2) at least partially deposits as a layer on the at least one rod (2). The layer of the re-deposited material has a surface hardness which substantially corresponds to the hardness of the material of the at least one rod (2).

Abstract: A dental jacket made of a hard, solvent free, substantially non-hydrophilic polyurethane elastomer. The jacket elastomer has a hardness of not less than about Shore D65. A polyester or polyether polyol with a functionality greater than two and a molecular weight greater than one hundred is reacted with an isocyanate prepolymer prepared from one or more branched polyester or polyether polyols with a functionality greater than two; and then blending prepolymer and first polyester or polyether polyol with nanoparticles. In one embodiment, the polypropylene glycol triether and the isocyanate prepolymer comprises dicyclohexylmethane 4,4′-diisocyanate.
