Cephalometric Evaluation to Determine the Relationship between Hamular Notch Incisive Papilla Plane and Camper’s Plane’ in North-Indian Population (An In-vivo Study)

Aim and Objective: To determine the relationship between Hamular-Notch Incisive Papilla Plane and Camper’s Plane in edentulous patients. Also to know the relation between occlusal plane and ala- tragal line from superior, middle and inferior border of tragus to the inferior border of ala of nose.

Materials and Method: To assess the relationship between the occlusal plane and ala tragal line a template was made and subjects with template were subjected to lateral cephalograms and tracings were analyzed using Autocad software.

Results: Campers plane formed with the posterior reference point as an inferior point of the tragus was relatively parallel to the HIP (CPI-HIP). As per the results of multiple comparisons, there was no statistically significant difference between CPM-HIP and CPI-HIP. CPI and CPM were considered to be relatively parallel to the HIP.

Conclusion: In male and female both age group ≥55 years, it was inferred that the Camper’s plane I [i.e. the plane drawn from the lower border of ala of nose to the inferior border of tragus] was relatively more parallel to the occlusal plane. In the age group <55 years, it was inferred that the Camper's plane M [i.e. the plane drawn from the inferior border of ala of nose to the middle border of tragus] was relatively less parallel to the occlusal plane.
