Evaluation of alveolar bone grafting using limited cone beam computed tomography. There is a growing awareness of the need for economic evalua-tions in dentistry and further understanding in this field is a prerequisite since the diagnostic examination forms the basis for treatment planning and prognostic assessment. Axial section at mid-crown d , cemento-enamel junction e and mid-root f of the transposed teeth demonstrate details of tooth—tooth and tooth—bone relationships.

Effect of buccolingual root angulation on the mesiodistal angulation shown on panoramic radiographs. From the perspective of utility of CBCT as a diagnostic and treatment planning tool for transverse corrections, recent attempts have been made to understand if thesus maturation could help predict the relative magnitudes of skeletal vs dental expansion expected in patients undergoing RME with inconclusive findings.

CBCT in orthodontics: assessment of treatment outcomes and indications for its use
However, because of the position of the bond on toic tooth cingulum and despite desirable force vectors, it is likely that the cusp tip has continued to move along the root of the lateral incisor contributing to root resorption and difficulty in retrieval. An analysis of the mesiodistal measurements of these unerupted teeth revealed that the tooth marked with an asterisk most closely matches the contralateral lateral incisor morphologically and dimensionally, while the tooth marked with an arrowhead is almost 1 mm larger mesiodistally than the contralateral lateral incisor.

Manufacturing splints for orthognathic surgery using a three-dimensional printer. Besides aiding in tooth localization, CBCT is also valuable in determining the optimal site for surgical access to an thesiss tooth and more importantly contributes to significantly higher confidence in a clinician’s diagnosis and treatment planning than does the combination of panoramic, periapical and occlusal radiographs that traditionally have been used for this purpose.
Ever since, several CBCT systems have evolved that have been extensively used in the field of medical clinical imaging.

Pre-treatment CBCT images of a patient with bilateral complete transpositions of the maxillary canines and first premolars demonstrate the possible restrictions placed by boundary conditions on treatment options. Bimaxillary protrusion in which orthodontic treatment aims to reduce the dentoalveloar prominence is an example of a patient plus treatment-specific variable that can contribute to compromised alveolar boundary resulting in dehiscences following incisor retraction.
