Direct Measurement of Loads at the Temporomandibular Joint in Macaca arctoides

Abstract

Loads at the articulating surface of the head of the condyle were recorded in one male adult Macaca arctoides. Following surgical implantation of the pressure-sensitive foil, the monkey was given hard and soft foods to chew. Loads were recorded during incisal biting and molar chewing. The bite data showed the following: The condylar head was loaded during molar chewing with a maximum load of 1-3 lb. The condylar head was loaded with a larger load of 3-4 lb during incisal biting.
