Why Expose the Canine Teeth?
The presence of canine teeth act as the cornerstone of oral upper/lower arches and add stability to the entire dentition. Canine teeth are demensionally the longest teeth and provide greater ability to incise foods. They help guide our lateral excursive movements and help form the esthetics of our dentition alignment. Research shows that the cause of canine impactions is mainly hereditary, therefore genetic. Canine impactions are more frequent among females than males (F : M = 2.3 : 1) or 1.17% of females and 0.51% of males. And, as it was previously mentioned, 85% of impactions are palatal impactions compared to 15% that are vestibular impactions.
Reasons Why Canines should be exposed
1. Arch Stabilty
The canines are one the widest and longest tooth type in the dentistion and its presence gives the arch great stability. The canine has a greater propensity of preventing migration of the adjacent teeth.
In the absence of canines, the arch is less stable and dentition aligment becomes increasingly weaker.
2. Cyst Potential
Cysts can develop in the presence of any impacted tooth and the canines are no exception. Dentigerous cysts and ameloblastomas are the most prevalent of this type.
3. Damage To Adjacent Teeth
Many times impacted canines are positions in a manner which compromises adjacent teeth. In many instances the canines cause resorption of adjacent teeth and possibly delayed eruption of teeth in their proximity.
