A Comparison of the Process of Remodeling of Hydroxyapatite/Poly-D/L-Lactide and Beta-Tricalcium Phosphate in a Loading Site

Figure 7

Tissue sections were stained by silver impregnation and observed at ×40 magnification. ((a), (c), and (e)) TCP group. ((b), (d), and (f)) HP group. ((a), (b)) 1 month. ((c), (d)) 3 months. ((e), (f)) 12 months. (g) Measurements of the infiltrated fibrous tissue. β-TCP (grey box), HA/PDLLA (black box). (g) The TCP group showed little fibrous tissue infiltration during the follow-up period. On the other hand, the HP group showed a stronger fibrous tissue infiltration than did the TCP group. : versus TCP group. †: versus 1 month. §: versus 3 months. Scale bars: 500 µm.
