In Vitro and In Vivo Analysis of the Effects of 3D-Printed Porous Titanium Alloy Scaffold Structure on Osteogenic Activity

<div>(a) X-ray examination results of femur samples after scaffold implantation. (b) Micro-CT 3D reconstruction results. Yellow is bone tissue, and white is porous titanium alloy scaffold. (c) Results of new bone tissue parameters by micro-CT scanning in scaffold. (d) Fluorescent labeling results of newborn bone tissue in titanium alloy porous scaffold (multiple: ×200). Calcein labeled new bone tissue in green and titanium alloy material in black. (e) VG staining results of new born bone tissue in porous titanium alloy scaffold (multiple: ×200). Red is mature new bone tissue, brown gray is bone marrow tissue, and black is titanium alloy material. (f) Percentage of new bone area in porous titanium alloy scaffolds of the two groups. <svg height="10.7395pt" id="M20" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162 -10.1025
