Hypothesis
Does the variation in vertical facial pattern affect maximum occlusal force and medial mandibular flexure?
Conclusion
The study found that maximum occlusal force and medial mandibular flexure did not vary with vertical facial pattern in the sample of Brazilian adults.
Supporting Evidence
- No significant difference of maximum occlusal force or medial mandibular flexure was found among the three facial patterns.
- Males had higher maximum occlusal force values than females.
- The study's sample was predominantly brachyfacial.
Takeaway
The shape of your face doesn't change how hard you can bite or how your jaw flexes when you open your mouth.
Methodology
The study used cephalometric analysis to classify subjects into facial pattern groups and measured maximum occlusal force and medial mandibular flexure.
Potential Biases
The study may not represent the broader Brazilian population due to its convenience sampling method.
Limitations
The sample had an unequal distribution of facial patterns and was drawn from a convenience sample of dental students and staff.
Participant Demographics
Participants were fully dentate adults aged 20 to 50, with a predominance of brachyfacial types.
