Statement of Problem: Difficulty in accurate location of occlusal piane due to individuai variability and uncertainty of landmarks among edentulous subjects.
Purpose: To establish the reliability of certain intraoral anatomical landmarks in establishing the occlusal piane in edentulous subjects.
Materials and Methods: Samples of 75 edentulous subjects of both the sexes were selected randomly. A vestibular impression to record the corner of the mouth and buccinator groove was made in 25 subjects. In 50 subjects, parotid papilla and retromolar pad were located and the relation of both the landmarks was recorded to the established ala-tragus piane.
Results: Analysis showed the consistency of occlusal piane established from the corner of the mouth through the buccinator groove using a vestibular impression method. The retro molar pad also showed a consistent relation with the occlusal piane. However, the parotid papilla showed a variable relation with the occlusal piane.
Conclusion: Corner of the mouth, buccinator groove and retro molar pad are reliable guides in accurate location of the occlusal piane in edentulous subjects whereas parotid papilla can only be used as an adjunctive aid in the determination of occlusal plane.
