Digitalized measurement of maximum bite force in Iraqi adult sample aged 18 - 25 years with different malocclusion groups

Abstract

Information concerning the maximum bite force in human population is important to clinical orthodontics. Additionally, the influence of bite force on the vertical stability of any treatment result is important. The new position of the dentition should be compatible with the dynamics of the muscular and occlusal forces in all planes. This study was conducted to assess the maximum bite force in the molar (left and right) and incisor region of Iraqi adult persons aged 18-25 years. Materials and method: The total sample size is (150) persons (75 male, 75 female) of untreated Iraqi subjects divided according to the class of malocclusion. The maximum bite force measurements were performed by a digital device (GM10) placed in the first molar area unilaterally on both the left and right sides which was used especially for this study. After that measured the maximum bite in the right central incisor region. Results: The maximum molar force was higher in class III followed by class II and then class I. The maximum incisal force was higher in class I followed by class II then class III. Conclusions: there was a very high significant difference between molar and incisal bite force. There was non significant difference between right and left side in all classes of malocclusion. Generally there was a very high significant difference regarding the genders, males have a greater bite force than females for class I, II, III
