Skeletal, Dentoalveolar And Soft Tissue Parameters In Individuals With Palatal Maxillary Canine Displacement

Background: Studies reported on the skeletal relationship in subjects with palatally displaced canines were minimal.
Aim: To determine skeletal, dentoalveolar and soft tissue parameters in subjects with palatally displaced canines and to compare them with subjects with normally erupting canines. 
Material and Methods: A total of 120 lateral cephalograms for palatally displaced canines subjects were collected (70 females, 50 males; age 17.173.09 years). A control sample with no canine displacement matched the study group were included. Lateral cephalograms were traced and measurements were calculated.
Results: Majority of palatally displaced canines subjects (62%) had Class I skeletal and (33%) class II division 2 incisor relationships. Palatally displaced canines subjects had smaller maxillary and mandibular body lengths, smaller Mx-Mn and SN-Mn angles, reduced AFH, increased inter-incisal angle, smaller mandibular anterior and posterior dentoalveolar heights and retrusive upper and lower lips compared with the controls. 
Conclusions: Palatally displaced canines occurred mostly in Class I skeletal and class II division 2 incisor relationships with reduced vertical dimensions, short maxilla and mandibular body, small dentoalveolar heights and retruded upper and lower lips.
