Lasting (weeks) pain after seating of crown on implant abutment? (photo)

Since the crown has been seated on the implant (with maxillary sinus lift, bone crafting) abutment I’m in constant pain (increased pain when force is applied to crown/implant) in the area around the implant. The pain increases when force is applied to the crown/implant. Clindamycin brought not pain relief. I have seen the dentist several times regarding this issue and one occlusal adjustment has already been done.
