Abstract
In the last decade, several investigators have reported that autologous and homologous fresh frozen bones (FFB) are effective materials to restore alveolar ridges previous to insert dental implants. Here we reported a comparative study between spiral implants inserted in FFB and native bone to evaluate their clinical outcome. Patients were grafted and spiral implants were inserted in the same surgical time. Several variables (patient, grafts, anatomic site, implant, prosthetic restoration) were investigated. Implant’ failure and peri-implant bone resorption were considered as predictor of clinical outcome. 51 implants were inserted in 12 patients. Implants were inserted to replace 8 incisors, 4 cuspids, 18 premolars and 21 molars. The mean follow-up was 14 months. No implant was lost. Peri-implant bone resorption (i.e. success rate) was used as predictor of clinical outcome but Kaplan Meier algorithm demonstrates that no studied variable has a statistical significant impact on clinical outcome. FFB and native bone havehigh and comparable survival and success rate. Spiral implants can be successfully inserted in native e grfted bone to performe an oral rehabilitationI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
