The Aberrant Canine Part 2: Treatment
From Volume 11, Issue 1, January 2018 | Pages 6-12
Article
The permanent canine usually erupts uneventfully, but occasionally it may fail to do so. When this occurs there is a potential for the adjacent teeth to be damaged. Even when it does not cause any damage, treatment of the ectopically positioned canine can present a substantial challenge to the orthodontist. Part 1 addressed the aetiology and diagnosis of the aberrant canine. Part 2 will discuss the various treatment options for the aberrant canine tooth.
Following clinical and radiographic investigations, treatment decisions can be made based, not only on the type of malocclusion, but more particularly on the presenting features associated with the aberrant canine. It is the management of this canine that will now be described.
The treatment options for the developmentally absent canine are either to accept the resulting malocclusion, to reopen the space prior to prosthetic replacement, or to close the space.
Space closure may be prudent, especially if a good contact can be made between the lateral incisor and first premolar, which is not always possible in the lower arch. The first premolar can provide an aesthetic camouflage solution for the missing canine, but in the upper arch may require buccal root torque, mesial rotation and selective grinding of the palatal cusp to achieve the desired aesthetic outcome (Figure 1).
