case_images: Intraoral examination of all quadrants revealed longitudinal fractures involving 27, 37, and 46 (Figures 2      -9). On visual inspection of 27, the fracture line was running mesiodistally involving both the marginal ridges (Figures 2 and 7). The fracture segments cannot be displaced, but they can be visualized by wedging with a probe (Figure 2).
