Three-dimensional (3D) micro-computed tomography (μCT) analysis. A Representative images of three-dimensional Micro CT reconstruction of MPS; B Axial images of MPS; C Coronal images of MPS; D Sagittal images of MPS; E The region of interest. BV, BV/TV and Tb. Sp were measured within ROI (2 mm × 0.8 mm × 1 mm) from the distal-palatal root of the first molar to the mesial-palatal root of the second molar and extended 400 μm from the bony edges bilaterally; Data were presented as mean ± SD. Differences were analyzed by one-way ANOVA (F–I). Comparative analyses of the Micro CT measurements on F suture width; G bone volume to tissue volume (BV/TV); H bone volume (BV) and I trabecular separateness (Tb. Sp). (* P < 0.05, ** P < 0.01, *** P < 0.001). Scale bar: 2 mm
