ObjectiveBehaviour of autogenous bone block in sinus lift and surgical consequencesStudy Design: Twelve sinus lifts with autogenous hip bone blocks and simultaneous insertion of two implants in 6 adult female sheep. Polychrome sequential labelling and histologic and histomorphometric evaluation after 6, 16 and 26 weeks.ResultsAugmentation material in the apical third was almost fully resorbed after 26 weeks (p=0.00388).Percentage of bone tissue increased 0.5-1.0 mm from the implant in crestal region (15.3 ± 7.5% to 16.2 ± 10.1%), while it vanished in the apical region from 16 to 26 weeks (4.2 ± 10.4% to 0 %). (p=0,363)ConclusionsAutogenous bone block leaves an apical thin but functionally crucial layer covering implants in a form follows function way.Denial of animal originated biomaterials and prion diseases remain a rarely discussed issue.The use of an implant length adapted autogenous transplant with osseoinductive advantages should be taken into consideration.
