We propose a simplified and computationally feasible model accounting for the dielectric
confinement in arbitrarily shaped many-electron quantum dots, within the local spin density
approximation. The model yields quite a good agreement with full configuration interaction
calculations including exact dielectric confinement. The model is used to study the influence of the
dielectric confinement on the electronic charge distribution of elongated quantum dots in the low
density regime. [-]
