PTH accelerated maxillary reconstruction of maxillary expansion model rats. The rats were divided into control, PTH, expansion and expansion + PTH groups, respectively. A The bone rebuilding of maxillary expansion model rats was determined using microCT method. B The BV/TV, BS/BV, TbN, Tb.Th and Tb.Sp were quantized, respectively. *P < 0.05 versus control group; #P < 0.05 versus expansion group. BV/TV, trabecular bone volume fraction; BS/BV, smaller specific bone surface; TbN, trabecular number; Tb.Th, trabecular thickness; Tb.Sp, trabecular separation
