In a patient with unerupted and impacted maxillary
canine, the following radiographic techniques will be ideal for localization:
Typically, the occlusal radiograph is especially useful in the following cases:​

To locate precisely roots and supernumerary, unerupted, and impacted teeth (this technique is especially useful for impacted ​canines and third molars)​.
To localize foreign bodies in the jaws and stones in the ducts of sublingual and submandibular glands​.
To demonstrate and evaluate the integrity of the anterior, medial, and lateral outlines of the maxillary sinus​.
