Electroweak radiative one-loop corrections to Higgs boson pair production in {ital t{bar t}} fusion processes are calculated in the two-Higgs-doublet extension of the standard model. The numerical size of the nonstandard corrections is discussed for the process {ital t{bar t}}{r_arrow}{ital H}{sub 0}{ital H}{sub 0}. The relative difference between the predictions of the two-Higgs-doublet model and the minimal standard model for a light scalar {ital M}{sub {ital H}{sub 1}} and heavy {ital M}{sub {ital H}{sub 2}} and {ital M}{sub {Phi}} easily exceeds {minus}10{percent} in the forward and backward directions. In particular the angular-dependence corrections owing to the nonstandard Higgs bosons get larger where the box and cubic Higgs boson vertex corrections constitute the dominant part of the radiative corrections. {copyright} {ital 1996 The American Physical Society.}
