Fig. 3From: Morphometric and histomorphometric evaluations of high-purity macro/microporous beta-tricalcium phosphate in maxillary sinus floor elevation: preliminary results on a retrospective, multi-center, observational studyUse of HPMM β-TCP with a resorbable collagen membrane in sinus floor elevation. In all cases, the sinus membrane is covered with a resorbable collagen membrane (Bio-Gide®, Geistlich Pharma AG, Wolhusen, Switzerland). The space between the lifted sinus membrane and the sinus floor is filled with HPMM β-TCPBack to article page
