Fifteen patients were selected, each presenting at least two jaw front teeth indicated for
extraction: in the Test Group (TG), post-extraction sockets was filled by synthetic bone
substitute ReproBone, and in the Control Group (CG) the socket was filled only by clot. In
both groups, the sockets were covered by a resorbable collagen membrane BioMend, which in
turn was covered by a flap. Computed tomography scans were acquired in the immediate
postoperative period and 6 months after surgery, and the horizontal and vertical dimensional
changes in bone crests were quantified.
