Page 24: Radiographic Techniques: Long Cone Technique
ORIX 70 OPERATING INSTRUCTIONS RADIOGRAPHIC TECHNIQUES: LONG CONE TECHNIQUE With the long cone technique, the film surface is set parallel to the axis of the teeth. The film is normally placed away from the portion of teeth that comes in contact with tongue with the exception of the lower molars.
Page 25 ORIX 70 OPERATING INSTRUCTIONS a) Place the anterior side of the film on the median line of the lateral incisors. The contact point of the canine must be visible on the x-ray image. b) Place the film at a sufficient distance from the tongue as to reproduce the whole tooth.
Page 26 ORIX 70 OPERATING INSTRUCTIONS b) Place the film in the deepest area of the mouth and at a sufficient distance from the tongue. c) Place the film parallel to the longitudinal axis of the premolars and parallel to the oral surfaces of the crowns.
Page 27: Typical Inconveniences Of Intra Oral Films
