Implants inserted into homografts bearing fixed restorations.
OBJECTIVE
In the last decade several studies have evaluated the clinical outcome of implants inserted into autografts and rehabilitated with fixed restorations in either one- or two-step surgical protocols. However, no study has investigated implants placed into homografts; thus, a case series analysis was performed to verify the clinical outcome of implants inserted into fresh frozen bone (FFB) and bearing fixed prosthetic restorations.


METHODS
Fifty-eight patients underwent iliac crest homograft transplants and 238 implants were inserted. Seventy-one double-etched, 19 sandblasted and acid-etched-1 (SLA1), 10 grit-blasted and acid-etched, 73 anodic oxidized, 39 CaPo4 ceramic-blasted, 19 SLA2, and seven additional implants of various types were used. Implant diameter and length ranged from 3 to 5 mm and from 7 to 16 mm, respectively. Implants were inserted to replace 15 incisors, 14 canines, 102 premolars, and 107 molars. A total of 111 restorations were performed.


RESULTS
No implants were lost. Cox regression analysis showed that implant type and type of edentulism directly correlated with a lower bone resorption and thus had a better clinical outcome and success rate.


CONCLUSIONS
Implants bearing fixed restorations and inserted into FFB have higher survival and succes rates compared to those placed in nongrafted and grafted jaws reported in previous studies.
