Nankali's Masticatory Force Systematization force of the masticatory system and discovered the differences in the produced force, which was approximately doubled. The periodontal system controls automatically the measure of mastication force in this process and the jaw elevator muscles develop the main forces used in mastication. Dr. Weber worked out that 1 cm cross section surface area of any masticatory muscle can produce approximately 10 kg force. The following average surfaces were found: temporalis - 8 cm, masseter - 7.5 cm, and medial pterygoid - 4 cm which makes a total of 19.5cm. However, this force in some people is measured up to 3900N
Angle of the mandible Angle of the mandible The angle of the mandible (gonial angle) is located at the posterior border at the junction of the lower border of the ramus of the mandible. The angle of the mandible, which may be either inverted or everted, is marked by rough, oblique ridges on each side, for the attachment of the masseter laterally, and the pterygoideus internus (medial pterygoid muscle) medially; the stylomandibular ligament is attached to the angle between these muscles. The forensic term for the midpoint of the mandibular angle is the gonion. The gonion is a cephalometric landmark located at the lowest,
