Clinical Study
Histologic and Histomorphometric Comparison between Sintered Nanohydroxyapatite and Anorganic Bovine Xenograft in Maxillary Sinus Grafting: A Split-Mouth Randomized Controlled Clinical Trial
Figure 4
Biomaterial particles of both groups appeared to be surrounded and merged by newly formed bone. Several haversian systems () were noted in the newly formed bone. NHA: sintered nanohydroxyapatite; ABB: anorganic bovine bone; VB: vital bone; MS: marrow spaces (Toluidine Blue and Azure II; original magnification: 100x).
