What I understand from the case posted sir, if it’s possible to post some xrays, clinical photographs, working casts etc could help more in understanding the situation.
Coming with the available information, whenever screw is tight but still crown is mobile, according to me, load is transmitted not onto screw but to the implant abutment connection due to OCCLUSAL OVERLOAD (as metal island is there due to less INTEROCCLUSAL space).
This could lead to Implant Fracture…
One more important thing to be noticed is also how tight are the contact areas, as that also may influence this.
Be cautious about this and if possible correct the Occlusion and, if not adjustable, may have to repeat the Prosthetics for long term peaceful sleep and long term success of prosthesis.
All the Best…
