Try the many tips provided in this link to retrieve your items. They may be buried in the ground for example, or accidentally became invisible. Also check your prim count. Did the available prims number lowered after you rezzed your objects? In that case, that means they have to be on your land. Good luck!

By any chance did you rez them on the suface of a cut megaprim? If you did, they most likely rezzed at the boundary of the uncut surface of that megaprim.
