Abstract
RTG projections are essential for diagnosis, treatment plan, follow-up and treatment outcomes.
Three-dimensional (3D) cephalometry, which is done using a cone- beam computerized tomography
(CBCT) examination, allows more detailed evaluation of the craniofacial hard and soft tissue structures than 2D radiograph. Using 3D analyses in diagnostic and treatment planning in orthodontics is more
than necessary in cases with impacted teeth, cleft lip, and skeletal discrepancies requiring surgical
interventions. CBCT has come into wider usage in other situations as root resorption,
temporomandibular joint (TMJ) morphology and pathology, supernumerary teeth, alveolar boundary
conditions and asymmetries; maxillary transverse dimensions and maxillary expansion; vertical
malocclusion and obstructive sleep apnoea.
The present descriptive study aimed to explore possible applications of 3D technologies during
the diagnosis, treatment plan, case monitoring and result assessment in orthodontics including their
advantages and disadvantages.
Utilisation of 3D technique was more than necessary in diagnostic and treatment planning in
this case because of presence of more than one impacted tooth. The fixed appliances, the surgical
exposure, cortectomy and orthodontic traction were done. The tooth movement and positioning to the
dental arch started six months ago.
The impacted tooth is already seen and the treatment continues. The severity of this case is
indication for utilization of control 2D and 3D radiographs in manner following the positioning of the central incisor on the appropriate place. 3D technique is less prone to error and can improve the
clinicians’ workflow.
