Summary
The ala-tragus line is not parallel to the occlusal plane in dentate subjects. This finding suggests the ala-tragus line is not a reliable guideline for establishing the occlusal plane in complete denture construction.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Anatomy
Background:
- Establishing the occlusal plane is crucial for complete denture fabrication.
- Preclinical determination of the occlusal plane aids in clinical success.
Purpose of the Study:
- To assess the parallelism between the occlusal plane and the ala-tragus line in dentate individuals.
- To evaluate the ala-tragus line as a potential guideline for setting the occlusal plane in edentulous patients.
Main Methods:
- A comparative study analyzed 120 dentate subjects using photographs taken with a Fox plane.
- Digital image analysis software (Digimizer) measured angles between reference points: superior, middle, and inferior tragus (ATs, ATm, ATi) and the ala of the nose.
- Angles were computed between the Fox plane (FxP) and lines drawn to these reference points using SPSS for statistical analysis.
Main Results:
- Mean angles between the Fox plane and the ala-tragus reference points on the right side were 3.261°, 2.720°, and 2.245°.
- Mean angles on the left side were 2.347°, 2.558°, and 2.029°.
- These values indicate a lack of parallelism, as the angle values were not close to zero.
Conclusions:
- The study found no significant parallelism between the occlusal plane and the ala-tragus line in the evaluated dentate subjects.
- The ala-tragus line may not serve as a reliable anatomical landmark for establishing the occlusal plane in complete denture construction.

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
