The search is particularly sensitive to top-antitop resonant production. We use the full data sample of proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected by the CDF II detector at the Fermilab Tevatron, corresponding to an integrated luminosity of 9.45 fb$^-1$. No evidence for resonant production is found and upper limits on the production cross section times branching ratio for a narrow resonant state are extracted. Within a specific benchmark model, we exclude a $Z'$ boson with mass below 915 GeV/$c^2$ decaying into a top-antitop pair at the 95% credibility level assuming a $Z'$ boson decay width of $\Gamma_Z' = 0.012 M_Z'$. This is the most sensitive search for a narrow $q\barq$-initiated $t\bart$ resonance in the mass region below 750 GeV/$c^2$.
