METHODS Cone-beam computed tomography images of 34 unilateral maxillary impacted canines (12 males, 22 females; mean age, 16.5 years) were collected. Twenty-one canines were palatally impacted (PIC), and 13 were buccally impacted (BIC). Angular measurements of lateral incisors (LIs), first premolars, and the impacted canines positions relative to a 3-dimensional coordinate system and canines' volume, length, and shape of the roots, were compared between the affected and contralateral control sides. The influence of canine position and severity of impaction was examined. Statistics included the paired t test, Wilcoxon signed rank test, and McNemar test. RESULTS In the PIC group, LIs showed significant mesiobuccal rotation (-17.1°), mesial angulation (8.4°), and buccal root torque (5°) and first premolars mesiobuccal rotation (6.1°). In the BIC group, LIs displayed mesiobuccal rotation (-18°) and significant palatal root torque (-5°). The canine volumes were similar in BICs and slightly smaller in PICs. The lengths were shorter in both, but root hooks were more prevalent in BICs. The severity of impaction affected the measured variables. CONCLUSIONS The differential position of the adjacent teeth is pathognomonic for PIC vs BIC, and impaction seems to affect canine development. The findings provide evidence-based clinical and radiographical clues for early diagnosis of canine displacement and planning the most efficient treatment strategy. In addition, they support timely orthodontic eruption before the development of the apical third of the root.

A sample of 20 patients with a variety of types of tooth impaction was investigated and five representative cases are described. The potential disadvantages of digital volume tomography--inferior spatial resolution of subtle structures and limited representation of soft tissues--were of no clinical significance in the presented cases of impacted teeth. The method provides 3-dimensional images closely akin to regular computerized tomography imaging, yet the amount of radiation produced is less than one sixth that for regular computer tomography and its cost is considerably less. There is reason to recommend the routine adoption of digital volume tomography imaging for positional diagnosis in most cases of impaction of teeth that are candidates for orthodontic resolution.
