Occlusal radiography is defined as those intraoral radiographic techniques taken using a dental X-ray set where the image receptor (film packet or digital phosphor plate – 5.7 × 7.6 cm) is placed in the occlusal plane. Suitable-sized solid-state digital sensors are not currently available.
The terminology used in occlusal radiography is very confusing. The British Standards Glossary of Dental Terms (BS 4492: 1983) is inadequate in defining the various occlusal projections and in differentiating between them. The result is that there is still little uniformity in terminology.
The terminology used here is based broadly on the British Standards terms, shown in parentheses, but they have been modified in an attempt to make them more explicit, straightforward and practical so that often the name of the view indicates how it is taken.
2. The image receptor, suitably barrier wrapped, is placed flat into the mouth on to the occlusal surfaces of the lower teeth. The patient is asked to bite together gently. The image receptor is placed centrally in the mouth with its long axis crossways in adults and anteroposteriorly in children.
