Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Wide, bilateral chewing cycles were related to better masticatory performance, however, unilateral chewing was reported to be very common in population, and it has been associated to lateral asymmetry on bite force and occlusal contact area.
It has been reported that dolichofacial subjects need greater muscular effort during mastication when compared to meso and brachyfacial subjects. This may cause functional overloading of weaker masticatory muscles, and may lead to functional asymmetries.
