  A Lorentz symmetry violation aether-type theoretical model is considered to
investigate the Casimir effect and the generation of topological mass
associated with a self-interacting massive scalar fields obeying Dirichlet,
Newman and mixed boundary conditions on two large and parallel plates. By
adopting the path integral approach we found the effective potential at one-
and two-loop corrections which provides both the energy density and topological
mass when taken in the ground state of the scalar field. We then analyse how
these quantities are affected by the Lorentz symmetry violation and compare the
results with previous ones found in literature.
