The patient had also received therapeutic irradiation. One year after radiotherapy, three implants were placed in the remaining maxillary bone without any bone augmentation. One of the implants failed during the osseointegration period. The implant replacing the failed one also failed during prosthetic procedures. The patient was unwilling to undergo another surgical episode, and the final prosthesis was completed on the two remaining implants. https://fid.tums.ac.ir/index.php/fid/article/view/1964 https://fid.tums.ac.ir/index.php/fid/article/download/1964/1008
