The debrided socket is packed with mineralized cortical/cancellous mix (50/50. .5-1.0 mm) hydrated with ~ .25 ml of .3 mg/ml of rhPDGF-BB (one component of GEM21S, Fig.2,3). B: buccal. It appears that the bone graft particulates stick to each other (fuse) and bind to seemingly denuded the mesial surface of the mesial root of the tooth #32 under the influence of rhPDGF-BB. The periodontal space is expected to form.
