Table 1 3D morphometric analysis of the constructs retrieved 7 and 30 days after rapid maxillary expansion (RME). The characterization of the 3D mineralized microarchitecture of the newly formed bone showed that the struts number (BNr) significantly increase from 7 to 30 days after RME. Coherently, the spacing (BSp) significantly decrease and the Conn. D significantly increase from 7 to 30 days after RME
