Orthopan ( panoramic radiograph, digital orthopantomograph ) is the most frequent image reproducing the entirety of the maxillofacial region, including the temporomandibular joints (TMJ). It can also be made in digital form on a CD (digital panoramic radiograph) to enable viewing on a computer screen. All panoramic images are made with digital CCD technology and show all the captured structures with high precision, which allows for spotting more details and making a better diagnostic application. Optimal imaging geometry creates a precise image of the teeth of the upper and lower jaw without distortion. It clearly shows pathological changes around the roots of all teeth, the state of the bone in case of periodontitis and cavity lesions on the teeth. Diagnostically speaking, it is the most important image for a timely detection of the diseases of the teeth and surrounding structures.
Orthopan shows at the same time teeth of the upper and lower jaws with surrounding tissues and structures. It is considered a basic diagnostic method in stomatology and is often developed as orientation image at the first examination. It is required in prosthetic treatment planning, in orthodontics and oral surgery when planning implant placement or removal of impacted teeth. Orthopan can be applied to the children because it is adapted small amount of radiation. The only group that is not supposed to take orthopan are pregnant women, especially in the first quarter.
