Giải thích
An occlusal radiograph uses a large receptor held between the occlusal surfaces and shows a wide segment of the maxilla or mandible, making it useful for locating fractures, impacted teeth, and salivary stones. Vertical bitewings show crowns and bone levels of a limited region. A cephalometric image is an extraoral skull projection, and interproximal is another name for the bitewing.
