Influence of talon cusp in occlusal planning for a pier abutmentNammazi AMI, Alkhayrat AMA, Nawaf MHA, Waseem HMA, Khurshid A Mattoo.
Developmental disturbance of the teeth and associated structures may present clinically in a very mild or severe form. An extra cusp may sometimes look innocuous but clinically may impact the entire occlusal scheme if present on a critical tooth surface. Talons cusps are basically a form of dens evaginates that are present on palatal surfaces of anterior teeth. This article describes a case of the presence of a talon cusp on a deciduous maxillary canine in permanent dentition, whose anatomical features were not distinct. The patient also had a pier abutment on the same side. Rehabilitation of the missing teeth was done by fabricating a fixed-movable bridge in relation to the pier abutment in two different sections. The influence of the talon cusp on existing occlusion was minimal, although occlusal influences of such abnormality have been discussed.
