I require help for this case

 Since the posteriors are present and in occlusion i dont think bite raising is required and what vertical dimension is lost should be restored by the crowns placed on the anteriors

Do correct me if this idea sounds inappropriate or if i have not been able to gauge the need of raising the bite

there is hardly any space for crowns in the lower anteriors. Bite raising will be required. If I put crowns without bite raising the crowns on the lower anteriors will come out.
