Abstract

This study was conducted to evaluate the influence of the frontal dentoskeletal form in complete denture wearers on the lateralized masticatory index and the direction of the bite force.<BR>The frontal dentoskeletal forms of eleven complete denture wearers in the normal face group were analyzed by posteroanterior cephalograms. The subjects were divided into left and right deviation groups, and the mechanisms of their jaw functions were analyzed in terms of the lateralized masticatory index and bite force angulation in the horizontal plane during vertical clenching. The magnitude of bite force was divided into two levels<BR>.<BR>As a result, it was found that the lateralized masticatory index was strongly influenced by the frontal dentoskeletal form and chewing habits during masticatory movement with relatively lower bite force.This suggested that the mandible function, including the direction of bite force and the frequency of the lateralized masticatory index, should be examined in detail to improve the right and left balance in the dentoskeletal form and denture retention and stability.
