Bovine hydroxyapatite (Bio-Oss®) induces osteocalcin, RANK-L and osteoprotegerin expression in sinus lift of rabbits

The aim of this study was to analyze and compare the expression of osteocalcin, RANK-L, osteoprotegerin, in sinus lift procedures using bovine hydroxyapatite (HA).Twenty four male rabbits underwent bilateral sinus lift procedures were distributed into two groups, according to the sinus filling material: Group 1) autogenous bone graft; and Group 2) bovine HA.
