We present a new technique for analyzing heavy-quark bound states in lattice QCD. The method is based upon a nonrelativistic reformulation of the heavy-quark dynamics that is systematically developed starting from the Dirac theory. It is far superior to traditional relativistic techniques, as we illustrate in a numerical study of the {Upsilon} and {psi} meson families.
