The patient came with a maxillary hybrid prosthesis supported by an All on 4 system. They complained of pain and swelling in the first quadrant. There is abundant suppuration in the right posterior implant area. The treatment plan starts with the removal of the infected implant and antibiotic therapy. Another surgery will be completed 1.5 months later with flap opening and local cleaning. Bone reconstruction will be done with Augma Bond Apatite®. Five months later a new implant is placed in the grafted site and a month after this the new implant is placed using the old prosthesis. Throughout the treatment the patient will use his prosthesis fixed on the three remaining implants.
