case report I Tab. 1_Specimen classification of surgical and prosthetic planning. I 19implants3_2015 All of the implants had shown similar radi- ographic findings: lack of osseointegration at the crestal third and crater-like vertical bone resorption in some cases. These findings were unexpected, tak- ingintoconsiderationthatnocomplicationshadoc- curredduringtreatment.Insomecases,patientshad received implants from other manufacturers on the contralateral side and these were functioning as ex- pected. After explantation, none of the osteotomies showed soft-tissue ingrowth. Also, regions that had been augmented showed no bone loss or wall de- fects. Based on these findings, we decided to replace all of the explanted implants but #006 and 008 (the first two failed implants) immediately with implants from different manufacturers. In all of the cases, the patients received prostheses after three to four months and the surgical and prosthetic treatments were successful.
