Vertical direction impaction of kissing molars: A case report

Figure 1 Teeth #17 and #67 in the vertical direction, showing impacted kissing molars.

Figure 2 Cone-beam computed tomography image of kissing molars, the root of tooth #17 appears close to the inferior alveolar nerve, the kissing molars and tooth #18 were close, and the distal bone of tooth #18 was absorbed. A: Coronal plane; B: Sagittal plane.

Figure 3 Classification of kissing molars according to the impaction direction (from left to right: Type A, vertical, Type B, tilted, Type C, transverse).

Figure 4 Kissing molars; the overlapping region of the two teeth, and the acute angle formed by the long axis of the two teeth should be considered when identifying kissing molars.
