Success rate of long implants inserted in fresh frozen bone.
J Pak Dent Assoc Dec ;17(2):86-91.

OBJECTIVE: To evaluate the clinical out come on a series of long implants inserted into homologue Fresh Frozen Bone (FFB). PATIENTS AND METHODS: This retrospective study was conducted in the period between December 2003 and December 2006, 33 patients were operated on at the Civil Hospital, Castelfranco Veneto, Italy and 85 Us inserted. The mean follow-up period was 28 months. Implant diameter and length ranged from 3.3 to 5.0 mm and from 14 to 16 mm, respectively. RESULTS: No implants were lost (i.e. SRV = 100%) and no differences were detected among the studied variables. On the contrary, Cox regression showed that implant diameter (i.e. narrow - implants, diameter 3.75 mm) and prosthetic restoration (i.e. removable dentures) correlated with a statistically significant lower delta IAJ (i.e. reduced crestal bone loss) and thus a better clinical outcome. CONCLUSION: FFB is a good material to be used in pre-prosthetic surgery. LIs inserted into FFB can be considered reliable, although a higher marginal bone loss has to be expected when wider implants and fixed prosthetic restorations are used.
