In the last decade, several investigators have reported that autologous and homologous fresh frozen (FFB) and cryopreserved homologue bones (CFFB) are effective materials to restore alveolar ridges previous to insert dental implants.

Abstract
In the last decade, several investigators have reported that autologous and homologous fresh frozen (FFB) and cryopreserved homologue bones (CFFB) are effective materials to restore alveolar ridges previous to insert dental implants. Here we reported a histological comparative study between FFB and CFFB. Patients were treated with a split mouth scheme for sinus lifting and bone grafting with FFB and CFFB. Eleven patients were enrolled, 9 males and 2 females, median age 51 years. They were treated at the Department of Maxillofacial Surgery, Civil Hospital,Castelfranco Veneto,Italy in the period January 2008 December 2008.The study was approved by Local Ethical Commetee. Histological evaluation was performed on bone speciments containing spiral between dental implants inserted in FFB and CFFB.However, FFB has an higher values of Vital Bone Volume Percentage suggesting it has higher potential in bone regeneration. In conclusion, iliac crest FFB and CFFB are valuablematerials for alveolar ridge augmentation and implant insertion. Spiral implants can be immediately inserted in grafted boneI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
