There is downward and palatal displacement of the crowns of image and image, which are mobile. Centric occlusion is not possible because of the slightly palatal position of image and image.

image What tests would you do prior to repositioning of the teeth?

Radiographs. Intraoral periapicals (Fig. 31.1) or an anterior occlusal view are needed to diagnose root fractures compared to luxation injuries. The upper lateral incisors should also be checked for injury. Consideration should also be given to taking radiographs of the lower incisors, which may also have received either direct or indirect trauma. Where there is no significant displacement of the coronal portion of a tooth with a root fracture, then an anterior occlusal radiograph will often detect root fractures that may not be so evident on periapical views. These radiographs will serve as baseline views prior to repositioning.

Vitality tests of all upper and lower incisors.
