Implant screw outside of bone. Opinions?

Hi, I went to Government Dental College for Dental implant for last molar teeth(not wisdom), where they initially didn't tell that students will do the implant until the 1st surgery day itself. And I've shared the xray of implant after 5 months from the day 1st surgery of implant was done, here abutment is also placed now. Now after everything is done, they are telling that spacing is very less for Zirconia crown (which they initially said it will fit), and telling to go for metal crown, and also keep trimming my teeth above (which was RCT zirconia crown, which they already removed) They are putting both up and down metal crowns (bottom is implant and above is RCT treated), but I wanted zirconia. Now seeing these xrays, I feel like they have made big error in screw placement and this is causing spacing issue, but they are not admitting their mistake. Anyone please help me here with your opinion. Should I trust those MDS students? Thank you
