| ABSTRACTBackground: Difficulties arise when attempting to imagine the interpupillary line and comparing it with the Fox planeguide and not more difficult than holding any instrument over the movable pupils just to demonstrate theinterpupillary line. The aim of this study was to introduce ear lobes as alternative landmarks for the interpupillary lineduring orientation of the occlusal plane. Also, the other aim was to compare the ear lobes with the pupils of the eyesto verify that they were indifferent as anatomical landmarks.Materials & methods: The alternative landmarks, ear lobes, were presented and the method for orienting the occlusalplane with these landmarks was introduced. Digital pictures of 30 subjects, who participated in the study, wereanalyzed to compare the parallelism of the interpupillary line with the ear lobes.Results: The results of this study showed that the interpupillary line was parallel with the line drawn between both earlobes for the same subject.Conclusion: The ear lobes were reliable and dependable alternative landmarks for the orientation of the occlusalplane and could be used with less effort than that of the conventional method utilizing the interpupillary line.Key words: earlobe, landmark, occlusal plane.
