Abstract

Purpose:
Was to compare between tracing method and Cone Beam imaging for recording Bennett movement and lateral condylar angle.
 
Material and methods: Ten completely edentulous patients were selected with ages ranged from 50-60 years, with average age 55years. Each patient received complete denture and teeth were arranged according to balanced occlusion concept. The lateral condylar angle was measured by Gothic arch tracer and with Cone Beam imaging for each side. The Immediate Bennett shift was measured using condylar tracing and the Cone Beam imaging for each condyle during its lateral shift.
 
Results: The result of this study showed that there was no significant difference between the Bennett angle measured by Gothic arch and the angle that get from Cone Beam and also there is no significant difference between the reading of immediate Bennett shift recorded by condylar tracer or Cone Beam.
 
Conclusion:
Within the limitation of this study, it can be concluded that, the Cone Beam recording can replace tracing method for recording Bennett angle and Bennett shift.
