From: Pulsed electromagnetic fields promote osteogenesis and osseointegration of porous titanium implants in bone defect repair through a Wnt/β-catenin signaling-associated mechanism

Figure 5

Effects of 6-week and 12-week PEMF exposure on the osseointegration of pTi implants in the region of bone defect via μCT scanning.

A tube volume with 6.0 mm diameter and 8.0 mm length was defined as the volume of interest (VOI), which completely covered the region of the pTi implant. (A) Reconstructed 3-D μCT images determined by the VOI and 2-D mid-coronal and mid-sagittal slices. The regions with white color represent titanium alloys and the areas with yellow color represent cancellous bones. (B) Quantitative comparisons of μCT characteristic parameters of trabecular bones between the Control and PEMF groups (n = 6), including bone volume per tissue volume (BV/TV), bone surface per bone volume (BS/BV), trabecular number (Tb.N), trabecular thickness (Tb.Th) and trabecular separation (Tb.Sp). Values are all expressed as mean ± S.D. *Significant difference from the Control group at 6 weeks with P < 0.05. #Significant difference from the Control group at 12 weeks with P < 0.05.
