Although the bisecting angle technique is still utilized and may be necessary in certain circumstances, the paralleling technique is the method of choice for intraoral radiography.
However, the use of bisecting angle technique remains relevant due to the increasing use of rigid digital receptors for intraoral radiography.
Rigid digital receptors are more difficult to place comfortably in the mouth particularly in children and the posterior regions of the mouth in adults.
The use of rigid digital receptors produces more retakes due to technical errors than phosphor plate receptors or film.
A good understanding of bisecting angle technique is necessary to correct dimensional errors associated with placement difficulties as well as instances when occlusal techniques are utilized for intraoral radiographic imaging particularly with rigid digital receptors.
