Purpose: To compare dimensional changes and bone quality of two different grafting materials used for socket preservation.
Materials and Methods: Thirty-three patients requiring extraction were recruited and randomly
assigned to receive: biphasic calcium sulfate/ hydroxyapatite (BCS/HA); bovine derived xenograft (BDX) or no grafting (Control). Ridge width (at −3 and −6 mm) and vertical distance from a
stent were measured at the time of extraction/grafting. Measurements were repeated at reentry
and core biopsies were harvested.
BCS/HA may be used as the material of choice for socket preservation with similar and sometimes even better results compared to BDX.
The significance of the greater residual scaffold found in the BDX
group on implant placement in these sites is yet to be determined.
