About

Digital transformation in the orthodontic field profoundly alters the way in which orthodontic treatment is perceived and delivered, moreover it aids in creating individualized orthodontic appliances.A crucial step in digital orthodontic planning in either indirect bonding or aligner treatment is localization of mesiodistal tip. Earlier, Panoramic radiographs were formerly recommended to assist clinicians in properly identifying mesiodistal root angulation. recommended to help clinician to identify mesiodistal root angulation accurately. Owens et al. recorded clinically significant variation between the radiographic and the true root angulation. Alternatively CBCT (Cone Beam Computed Tomography) guided mesiodistal root angulation assessment has superior clinical significance compared to the routinely taken panoramic radiograph . despite its accuracy ,CBCT is not justified as a part of diagnostic records for orthodontic treatment planning following the ALARA rule . To eliminate additional x ray dose Computer aided mesiodistal root angulation identification is provided by several softwares such as OrthoAnalyzer™ ,OrthoCAD® ,and SureSmile® , however, the accuracy remains questionable. These finding may point out the importance of studying the accuracy mesiodistal identification to carry on digital workflow without the radiographic guidance.
