Effects of Twin Inclined Plane Device on Adaptation and Ultrastructure Variations in Condyle of Growing Rats

Figure 8

The SEM images (magnification ×4,000; white dotted box ×10,000) of the posterior area of the condylar surface. The condylar surface of the control group shows a shallow wavy appearance and uniformly distributed collagen fibers. (e, f) The condylar surface in the experimental group at days 3 and 14 shows that the gel layer flaked off, and the internal collagen net was exposed with evulsion of the collagen fibers. (g) The condylar surface in the experimental group at day 30 shows that the changes in the condylar surface began to reverse, and tissue repair was observable around the altered areas. (h) The condylar surface in the experimental group at day 60 shows the repair processes, in which the fibers were slowly surrounded by the matrix, and the disorganized collagen fibers on the surface were less than those in the experimental group at day 30.
