Introduction:The most commonly practiced method of orienting the occlusal plane is to
make it parallel to the ala-tragus or Camper’s plane. This study was, therefore,
undertaken to evaluate the validity of Tragus used in marking “ala-tragus line” while
establishing the occlusal plane by measuring the angle between landmarks and their
parallelism with occlusal plane.
Aims & Objective:The objective of the study is to evaluate the reliability of the most
commonly used extra oral landmark i.e. Ala-tragus line in determination of occlusal
plane in edentulous patients by comparing it with dentulous subjects.
Materials& Methods:Lateral cephalograms of Dentulous subjects were taken & were
subjected to Cephalometric analysis after tracing. Angles between Ala-tragus line &
occlusal plane was measured & subjected statistical analysis.
Conclusion:It was found that Ala-tragus line is not parallel to occlusal plane in natural
dentition as an angle exists between the two. However, it can assist in locating the
occlusal plane in edentulous patients.
