【Purpose of Imaging】To examine the anterior maxilla and palate, determine the position of impacted or supernumerary teeth, assess buccolingual tooth relationships, and evaluate maxillary fractures or lesions.

【Projection angle】The central ray is directed along the long axis of the maxillary anterior teeth and enters the center of the film. With the head positioned horizontally, the ray forms an angle of approximately +60° to +65° to the occlusal plane.
