Changing the horizontal angulation would cause overlapping.When the distal surfaces of the canines are not visible on a premolar bite-wing image,the solution is to position the anterior edge of the receptor at the midline of the mandibular canine.Increasing the vertical angulation would cause foreshortening.Decreasing vertical angulation would cause elongation.
