Can a human bite be more forceful than a velociraptor?
By Gregory J. Sabino, Ph. D., Stony Brook ’16, contributing editor  

J aw movement is an orchestration of multiple muscles around the temporomandibular joint. During mastication in proper occlusion, the cusps of opposing teeth are guided into position with minimal contact time and minimal excess force. However, parafuncitonal habits, such as bruxism, can deal considerable damage to teeth and periodontal ligaments. Bite force is the amount of force that can be generated by the adductor muscle that is realized on the row of teeth. In sleep studies, observations show that nocturnal bruxism can even exceed voluntary maximal bite force by 40 to 50 percent.

Data from voluntary maximal bite force experiments range between 650 and 850 N for the average male. The second molar and supporting structures can withstand forces up to 1300 N. The human skull is quite efficient at generating bite forces, and our bite force related to body mass exceeds most primates. However, the strength of our musculature is the factor limiting our maximal bite.

In 1992, the record for the strongest bite of a modern human, according to the Guinness Book of Records was 4,337 N (975 lbf). While one can compare the strongest human bite to present day animals, how do we compare to extinct species such as dinosaurs? How would one calculate the bite force of animals that existed millions of years ago? There are three methods to calculating the bite force of dinosaurs, and each must make assumptions to reach their estimated value. Keep reading…
