CBCT and TADs in Contemporary Orthodontics
The introduction of cone-beam computed tomography (CBCT) and computer software in orthodontics has allowed orthodontists to provide more accurate diagnosis and treatment. The most common use of CBCT imaging allows orthodontists to visualize the precise position of supernumerary or impacted teeth, especially impacted canines. In doing so, the exact angulation of impaction and proximity of adjacent roots can be evaluated by orthodontists, allowing them to choose vector forces for tooth movement while minimizing root resorption. Even though 2-dimensional panoramic images can be used to view the position of the impacted canines, they have limitations because it is not possible to evaluate the impacted tooth position 3-dimensionally. An accurate knowledge of root position improves the determination of success in orthodontic treatment.
Temporary anchorage devices (TADs) offer a practical way to provide anchorage for various types of tooth movement, especially when used in concert with CBCT to aid in orthodontic diagnosis and treatment planning, treatment simulation, proper placement of TADs, and assessment of skeletal and dental changes.

Regeneration of Degenerated Dentitions
Degeneration of dentitions occurs as a result of loss of teeth and periodontium. The role played by the orthodontist in the reconstruction of the degenerating dentition has been influenced by an improved understanding of the tissue reaction to the interaction between orthodontics and periodontal treatment. By distributing the available teeth in an optimal position for prosthetic reconstruction and by generating necessary alveolar bone for implants the long term maintenance of reconstructed dentition is enhanced. Mini-implants as bone maintainers and semi-permanent replacements are demonstrated.
