The Born-Oppenheimer approximation provides a description of heavy-quark mesons firmly based on quenched Lattice QCD. The diabatic framework extends this description through the incorporation of unquenched Lattice QCD data on string breaking. This allows for a unified description of conventional quarkonium, made of QQbar, and unconventional quarkoniumlike mesons, containing meson-meson components as well. A successful description of the charmoniumlike and bottomoniumlike spectra comes out.
