Abstract

Background

Orientation of the occlusal plane is one of the most important clinical procedures in the prosthodontic rehabili- tation of edentulous patients but definitions of the ala-tragus line (ATL) causes confusion, because the exact points of reference for this line are not clear.

Aim

The aim of this study was to corroborate a correlation between Camper's plane and natural occlusal plane in normal dentulous subjects and to ascertain the most relevant posterior reference point for establishing Camper's plane.

Materials and methods

In this study, 40 subjects with com- plete natural dentition and Angel's Class I occlusal relationship were selected. The subjects were photographed in sitting erect posture with head unsupported while clenching on a fox plane. The angles between the following lines were measured using digital screen protractor, the occlusal plane and Ala to superior border of tragus, the occlusal plane and Ala to middle border of tragus, as well as occlusal plane and Ala to inferior border of tragus. Descriptive statistics, one sample t-test and, independent t-test were done to analyze the data.

Results

There was no parallelism between the occlusal plane and ATL with three different posterior ends and one sample t-test showed that the angles between them were significantly different from zero (p < 0.001). However, the inferior border of the ATL had the lowest mean angle, 1.99° (4.32) and was almost parallel to the occlusal plane.

Conclusion

Ala-tragus line from Ala of the nose to the inferior border of tragus as a posterior reference point can be considered as a reliable occlusal plane for complete denture fabrication.
