IS MASTICATORY FORCE AT MOLAR REGION ANALOGICAL TO STAPLING MECHANICS AND BOTH BELONGING TO AN UNIDENTIFIED LEVER SYSTEM?

For easy and clear understanding of biomechanics, the inter-relationships of simple machines and musculoskeletal functions have always been attempted and established. The masticatory biomechanics is still under research because there is wide range of findings on masticatory muscles including the lack of complete clarity on their line of actions and lever arms too. As a prospective contribution to advanced research on mastication and management of Temporomandibular joint, there are two innovative concepts discussed in this article; (1) Strong correlation between stapling mechanics and Temporomandibular joint biomechanics at molar region (2) Scope for a new unidentified lever system named as fourth class lever. The principal intent of this article is to share these two innovative concepts to be explored further for practical applications in the field of Physical therapy, Dentistry and Engineering.
