Magister Chirurgiae Dentium (MChD) / There is a paucity of studies that make use of the alpha angle as a diagnostic tool to assist with
the interceptive treatment, prognosis, treatment duration and surgical outcome of possible
maxillary canine impaction in orthodontics. While the literature is replete with studies that
utilise the sector method, the alpha angle is an alternative approach to assess the possible
eruptive outcome of the unerupted canine.
It has been reported that if the alpha angle is greater than 25°, there is the possibility of external
root resorption. However, if the alpha angle is more than 31°, the prospect of canine eruption
decreases even if the deciduous canine is extracted as an interceptive measure.
The dental pantomograph has historically been used to predict canine eruption or possible
impaction. The use of this method, however, is wrought with limitations. These limitations
include magnification, distortion and blurred images. The use of cone-beam computed
tomography has been advocated as a means to overcome these limitations.
