you are taking a maxillary topographic occlusal projection. How is the film placed in their mouth and how do you aim the PID?
- film in mouth with white side facing the maxilla and long edge is side to side, placing the film posterior
- the PID is at +65 and the PID is placed between the eyebrows and bridge of the nose
which occlusal film would you be taking if the film is placed with the white side towards the maxilla and shift to the left or right? where would the PID be placed with this radiograph?
- Maxillary lateral projection
- the PID through the contact areas of hte intended interest at a +60 degree near the top edge of the corner of the eyebrow.
what size film would you be using for a pediatric occlusal projection and how would you place it in there mouth? where would you place the PID?
- size 2 film
- placed side to side in mouth
- the PID would be at +60 with the ray directed through the eyebrows and bridge of nose
what film would you be taking if the white side of the film was facing the mandible and the long edge was side to side near the posterior? what would you be doing with your PID for this shot?
- mandibular topographic occlusal projection
- the PID is directed throught the midline of the arch centered on the film, at a -55 degree angle
where would the film be placed for a mandibluar cross sectional occlusal projection and what would you do with the PID?
- film is placed with the white side facing the mandible and the long edge is side to side
- the PID is at a 90 degree angle and is centered on the chin
what film would you be taking if you were using a size two film and the PID was directed center on the chin? what angle would the PID be at?
- mandibular pediatric occlusal projection
t/f the patient needs to bite down hard on the occlusal film to hold it in place
false! Bite gently dont eat it!
