Fig. 7 The low- and high- magni fication images in the control group, demonstrating new bone formation in the upper and lower groups at 4, 12 and 24 weeks after surgery. Each black bar of the low- and high-magnification images shows 1,000 and 500 μm, respectively. Discussion (cid:696)-TCP is widely considered an option for use as a bone grafting material. However, few studies have used porous (cid:696)-TCP particles for sinus lift with tissue engineering techniques. In order maximize the surface area for cell attachment and proliferation, we fabricated the scafold into a highly porous 3-D structure through a rela- tively simple processing method involving a conventional sintering procedure. Previous stud- ies have used a slurry of (cid:697)-TCP and potato starch to produce (cid:696)-TCP that was in a thermodynami- cally stable phase at temperatures above 1,100 °C.16 Uchino et al. found that HA formation is rarely observed on the surface of porous (cid:696)-TCP Journal of Oral Science & Rehabilitation Volume 3 | Issue 1/2017 49
