Figure 1. Midpalatal suture expansion in mice.
(A) Occlusal view of 6-weeks-old mouse maxilla. Experimental/expansion maxilla with the opening loop bonded to the first and second molars (left) and non-operated control (right).
(B) The F/Δ diagram for the opening loop. Deformation was measured for 10 different loops at three force levels. Linear regression analysis was performed to create the trend line (R2=0.98). Since the force-deflection curve was measured at room temperature ex vivo, it is likely that force-deflection is different when the loop is placed in vivo.
