Look, the radiograph shows thst at least 3 implants must have been placed immediately or late immediately after tooth extraction. These are the two rear in the lower jaw and the firt upper left. If the radiograph is directly after insertion, the findings sre regular. Nevertheless after so much time and ts not normal to have pain. It is possible that the teeth sockets where the implants where placed immediately were not fully decontaminated and after being sealed with inplants you got pain and pressure feeling there. This happens and it doesn't mean thwt the decision to place implants immediately was wrong. But having there pain, means thst these Implants should probably be extracted, wait for 6-8 weeks and repeat procedure. It then most probably worl fine.
