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 implants inserted in cryopreserved fresh frozen bones (CFFB) 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. 53 implants were inserted in 12 patients. Implants were inserted to replace 8 incisors, 4 cuspids, 21 premolars and 20 molars. The mean follow-up was 14 months. Three out of 53 implants were lost (i.e. survival rate SVR = 94.3%) and no differences were detected among the studied variables. Similar result was obtained by analyzing the crestal bone resorption around implant'neck (i.e. success rate). CFFB and native bone high and coparable survival and success rate. Spiral implants can be successfully inserted in native e grafted bone to perform an oral rehabilitationI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
