Ct Scan data

Hi everyone
i work on a bio mechanic project. i am going to simulate a mandible bone
with implant. at first i want to use Materialise Mimics V10 to convert Ct Scan
data of a mandible without implant to a 3D model. i thought i could edit
the exported file on the other software (Ansys or Abaqus) to add the
implant. but, exported file from mimics can not have any edit .Actually
it has not volume and i need to have a 3D solid model. please help me !
