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 6

The new bone around some NHA particles presented osteons (), indicating a relative angiogenetic potential of the material. Vessels’ growth was present in pores of adequate dimension inside the biomaterial (black arrow). NHA: sintered nanohydroxyapatite; ABB: anorganic bovine bone; VB: vital bone; MS: marrow spaces (Toluidine Blue and Azure II; original magnification: 100x).
