[Impacted canine tooth and the eyebrow: the orbit-eyelid impact of occlusal dysfunction].
The orbital region and the dental occlusion are biomechanicaly interdependant. The maxillary basal bone is located in the orbital region due to the presence of the maxillary sinus. Any trouble of the dental occlusion such as a retained canine can involve a lack of projection of the supra and the infra-orbital rim. This lack of projection of the infra-orbital rim is responsible of lower eyelid fat pad; the lack of projection of the supra-orbital rim is responsible of an eyebrow-forehead ptosis. Clinical variations can be observed according to the side of the preeminent eye.
