Diagnosis and Treatment of Impacted Maxillary Canines Using CBCT

Cone-beam computed tomography (CBCT) imaging allows orthodontists to visualize the precise position of impacted canines and proximity of adjacent roots. 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.

Learning Objectives:

  • Describe the clinical situations for which CBCT is used
  • Discuss how to diagnose impacted maxillary canines through radiographs
  • Discuss factors associated with orthodontic treatment of impacted maxillary canines


Proper Inclination of Each Whole Tooth Relative to its Respective Alveolar Process

Conventional wisdom has suggested teeth should be centered over basal bone. Dr. Tong will discuss testing that hypothesis with a program he and his associates developed to measure inclination of teeth’s long axes and their respective alveolar process using CBCT. They compared the two measurements from 76 near-normal subjects, demonstrating the proper angular relationship between teeth and their alveolar housing. Dr. Tong will share the results of this program.

Learning Objectives:

  • Illustrate proper inclination of each whole tooth and its respective alveolar process
  • Assess the relationship between these two measurements
  • Determine inclination deviation from the norm when assessing clinical cases
