large areas of the jaw
what are the uses of the occlusal technique?
supplemental technique, locate, evaluate, and aid in examination
what are the three principles of the occlusal technique?
1. position white side of film facing teeth to be radiographed
2. film is placed between occlusal surfaces
3. film stabilized by patient occluding
what is the mandibular cross sectional?
patient tilts head back until man arch is almost perpendicular to floor
what do you use for all other projections?
max arch parallel to floor and midsagittal plane perpendicular to floor
