THE ADVANTAGES OF USING CONE BEAM CT TO DETERMINE THE POSITION AND RESORPTION OF MAXILLARY CANINES

Objective. The aim of this research is to find the neighboring incisors resorption and maxillary canines’ impacted locations using “Cone-beam Computed Tomography” or CBCT. Study Design. A number of 210 IMC were examined through CBCT images. New Tom (propriety software) was used to take linear and angular measurements after locations of IMC were evaluated. Also, the investigation of NI of root resorption was carried out. Results. The results showed 45.20% buccal-labially impacted, 14.30% midalveolus, and 40.50% palatally impacted. A varied location included n_8 inverted impactions, n_18 horizontal impaction, n_31 situ impaction, n_12 distal impactions, n_67 mesial-labial impactions, and n_74 mesial-palatal impactions. Quantitative measurements resulted a 27.20% of root resorption of lateral, central incisors 23.40% and 94.30% of resorptions were observed due to close contact of impacted canines with incisors. Conclusion. IMC location variation occurs in three planes greatly and resorption is common of permanent NIs.
