Disease relevance of Bite Force


High impact information on Bite Force

  • Influence of clenching intensity on bite force balance, occlusal contact area, and average bite pressure [4].
  • As the clenching intensity increased, the medio-lateral position of the bite force balancing point shifted significantly (P<0.01) from the preferred chewing side toward the midline [4].
  • Highly significant Pearson Product Moment correlation coefficients (p less than 0.005) were found between masseter and medial pterygoid cross-sectional size, and between the cross-sectional size of each muscle and bite force [5].
  • The CFA-mediated reduction of bite force and success rate was prevented in rats treated with anti-inflammatory agents administered intraperitoneally (dexamethasone, n = 5, or indomethacin, n = 5, 4 mg/kg) [6].
  • Then, growth series of M. domestica are used to assess how bite force potential changes with growth by evaluating craniodental changes using longitudinal sets of dorsoventral radiographs and by assessing maximal bite force potential at the Region I-II boundary of the jaw in juveniles (aged 70-80 days) and adults [7].

Biological context of Bite Force


Anatomical context of Bite Force

  • The bite force and occlusal contact area, which were mainly on the molars, increased with the clenching intensity, whereas the proportions of these two variables on each upper tooth usually did not change significantly [4].
  • The results indicated that the bite force and occlusal contact area on the whole dental arch increased with clenching intensity [4].
  • RESULTS: A multiple logistic regression analysis showed that whether participants had low bite force or not was significantly associated with gender, age, self-rated general health and occlusal support, but not TMJ noise or mouth opening limitation [10].
  • A multiple linear regression analysis, with stepwise maximum R2 improvement technique by forward selection and pair switching, was used to select the occlusal, morphologic, and histologic variables which explained most of the variation in bite force and electric masseter muscle activity [11].
  • The influence of craniofacial form on bite force and EMG activity of masticatory muscles. VIII-1. Bite force of complete denture wearers [12].

Associations of Bite Force with chemical compounds

  • Pain detection thresholds (PDTs) to pressure stimuli and maximal voluntary occlusal force (MVOF) were measured before capsaicin injection; 5, 15, and 45 minutes after the injection; and once a day for the following 3 days [13].
  • With even the static yield limit of titanium being exceeded in such cases, consecutive rapid failure of the miniplates becomes most likely when loading of the condylar region caused by bite forces cannot be prevented [14].
  • Consequently a study was carried out to determine the force required to fracture 20 randomly selected 25 and 32 ml polystyrene containers to see whether this exceeded the bite force of a child's jaw [15].
  • Bite force was tested during 'gentle biting', 'biting as when chewing', and 'maximal clenching'. Endurance tests and bite force discrimination tests were also performed [16].
  • CONCLUSION: Within the limitations of this study, zirconium implant abutments exceeded the established values for maximum incisal bite forces reported in the literature and tightly fit into the titanium implant after several millions of loading cycles [17].

Gene context of Bite Force

  • Surprisingly, the Mstn(-/-) mice demonstrated a disproportionate increase in bite force at higher stimulation frequencies with comparison of regression lines for force-frequency data (ANOVA, F=3.46, P<0.07) [18].
  • Bite forces from 4-month-old myostatin(-/-), dystrophin deficient (Mdx) and normal control mice were measured by load cell and field stimulation of the temporalis muscle [18].
  • The MASS and ZYGO muscles (and the PLAT in one of the monkeys) showed a significant increase in mean EMG amplitude during the holding phase compared with the pre-trial period, and the MASS showed the highest MAR. It was also the only muscle showing a significant increase in the EMG activity when the bite-force level was increased [19].
  • The bite force results obtained with the new bite force sensor and with the bite fork were analyzed with ANOVA and Scheffés tests [20].
  • Narrow-diameter ITI implants may be used to support FPDs for patients with low bite forces [21].
