Hi Marcel,
I’d agree with Dr. Sammy as you cannot reinstall the same implant once it has failed. At the very least, the implant site will need time to heal and must be properly evaluated to see if a bone graft and re-implantation with a new implant can be attempted at a later date. It would also be useful if your dentist could tell you why the original implant failed.
I hope you find a good solution.
Best regards,
Ali
