Application of direct magnification radiographic technique to the jaws

Direct magnification radiography is widely applicable to situations in which enhanced definition and enlarged images are desirable. This technique is capable of providing high subject resolution when conventional radiography is not definitive. It serves as a variable supplementary radiograph for the diagnosis of conditions in the oral and maxillofacial region. The general mechanics of the technique as well as its possible use as a supplementary high detail film are discussed. Three cases are reported in which this technique was applied in the diagnosis of oral and maxillofacial surgery patients.
