    ABSTRACT: 

     

     

    Introduction: Previous research by our group found condylar position to be a persevered attribute across the phylogenetic tree. Centric occlusion is determined by dentition, load, diet, environment, and masticatory muscles. There are several muscles involved in mastication including the temporalis, masseter, pterygoid, digastric, and multiple hyoid muscles; many of these muscles have subdivisions that work independently.

    Purpose: The purpose is to study the relation between dental loads, mastication processes and evaluate centric occlusion.

    Methods:  67 articles were obtained using PubMed, Science Direct, ResearchGate, and Google of which 12 papers were used to examine TMJ morphology and integration of its components.

    Results: The temporalis and masseter appear to be the most important muscles in mastication. It was determined that the greatest amount of variation in muscular activity occurred intra-species during different chewing cycles, rather than inter-species during the same chewing cycle. Although debate, there is support to suggest that mastication may simplistically be described as a class III lever system with the TMJ as the fulcrum. A support triangle is used for a more complex representation of the biomechanics involved in mastication. It has been observed that as bite force increases, TMJ resultant forces decrease, and bite point moves posteriorly. The Australopiths, as previously stated by our group diverged into gracile and robust forms which offered great insight into the study of centric relation and occlusion. While the two showed skeletal differences, the condylar position remained constant however dentition, loads, and muscular integration varied as a function of diet and positioning of the head. The gracile form displayed anterior dentition loading, and less developed temporalis and masseter muscles. This branch was unable to utilize their niche and thus became extinct. Using the support triangle biomechanics of mastication explains the dietary differences seen between gracile and robust forms.       

    Conclusion: Load position and muscular activity required for mastication is a function of diet therefore centric occlusion is primarily determined by diet.
