## 3 Treatment Plan Supported with Radiological Analysis  
Histopathological recognition supported by proper interpretation of OPG is the foundation for diagnosis. However, two-dimensional radiograph images have many limitations. The most significant are magnification and distortion of the image. Even if the patient is positioned properly, the object is enlarged by about 15-25% [13,12]. Moreover, magnification depends on the individual jaw shape and the area of the dental arch and is most apparent in the canine region [13]. Another problem is the overlap of structures and reflections of anatomical structures that can hinder interpretation [12]. Because of the reasons described above, panoramic X-rays are not sufficient to establish a treatment plan that demands a multidisciplinary approach; therefore, a cone-beam computed tomography (CBCT) examination is recommended. In order to plan optimal surgical access, surgeons need precise, three-dimensional information about the size and extent of the lesion that is not visible on the bucolingual display in OPG. Orthodontists require the accurate location of unerupted teeth, especially their spatial position relative to the roots of adjacent teeth, to assess the potential risk of root resorption during orthodontic traction [14]. The evaluation of alveolar

boundary conditions is another crucial factor that determines orthodontic mechanics [15]. Measurements should include vertical and buccolingual dimensions of the alveolar bone, as well as the relationship with the position of teeth. CBCT helps to determine the boundary of tooth movement to avoid iatrogenic fenestrations and dehiscence [15,16].  
In a study presented by [PERSON] et al. [17], conventional radiographs were compared with CBCT according to their utility in establishing a treatment plan for impacted maxillary amines. The change from the 2D technique to 3D imaging resulted in a difference in the assessment of the actual mesiodistal (21%) and labiopalatal (16%) cusp tip position, which brought about modifications in the treatment approach [17].  
An example of CBCT implementation in an orthodontic treatment plan is 3D biomechanics [15]. Because each patient with an odontogenic cyst presents a unique problem to solve, morphological reconstructions obtained with CBCT can be useful in planning the individual position of every orthodontic attachment and achieving a proper force vector. The distance of the virtual bracket from the center of resistance can be visualized, the tipping or translational movement can be better predicted, and the anchorage can be controlled [15].
