CBCT: The third eye in orthodontics

Abstract

Accurate diagnostic imaging is essential to derive the correct diagnosis and treatment plan in orthodontics. In two-dimensional diagnosis, geometric distortion, superimposition of structures, projective displacements, and rotational errors are common. This case series, affirming that the CBCT is vital key in the diagnosis of some specific orthodontic conditions, and presenting five case reports which was difficult to diagnose it with two-dimensional radiograph. Case 1 includes horizontally impacted 21 with crown located labially, and root palatally with close proximity to nasopalatine canal, which was veiled in 2D orthopantomogram. Case 2 is an infrazygomatic implant case, the placement of which was debatable by seeing through the 2D IOPA radiograph. Here, CBCT removed the black curtain and proved its monarchy. Case 3 is a premolar impaction, which in 2D radiograph appeared like an iceberg, but its true anatomy was revealed by the CBCT. After this, the next case 4 is about the central incisor mimicking a canine in 2D radiograph, which was found to be supernumerary tooth on CBCT. Followed by temporomandibular disorder (5) which severity was brought to light by CBCT. The need for this case series is to wave the flag for CBCT in the orthodontic diagnosis which will help in delivering proper treatment plan and emphasis where it is essential to do CBCT.
