A cephalometric study of incisor angulations in a Nigerian population.
This paper has the objective of establishing a standard norm for incisor angulations in a Nigerian population. The upper incisor angle to the Frankfort plane has a biological norm of between 119 degrees and 127 degrees, while the lower incisor angle (to the mandibular plane) is between 96 degrees and 104 degrees. The value for the interincisal angle is between 108 degrees and 116 degrees.
