“…Proffit et al 20) reported that long-faced individuals have less occlusal force than individuals with normal vertical facial dimensions. Park 19) reported that the main frequency of electromyography of Dolico-facial type subjects was lower than that of Brachyo or Mesio facial type subjects.…”

We examined the feasibility of applying the Dental Prescale Occluzer System ™ to the evaluation of occlusion in orthodontic patients. The patients were classified according to the type of malocclusion or facial pattern. The values of occlusal contact area and occlusal force obtained from these individuals differed depending on the type of occlusion or facial pattern. These values were higher in individuals with normal occlusion than in patients with malocclusion and higher in patients with the Brachyo facial pattern than in those with the Dolico facial pattern. Because this system can very easily analyze the occlusal contact area, the mean pressure on each occlusal contact point, and the occlusal force during the process of orthodontic treatments, it can be useful as an aid for the initial diagnosis of occlusal problems, the observation of the changes in occlusion during treatment, and the establishment of the final goal of orthodontic treatments.

“…Normal structure of the stomatognathic system is indispensable for proper physiological function. Previous studies 8,20) have shown that malocclusion patients have masticatory function that is inferior to the function in subjects with normal occlusion. This inferiority can be improved by orthodontic treatment.…”

“…In addition, mastication also has a substantial effect on craniofacial morphology. Previous studies pointed to a correlation between the maximum bite force (MBF) and facial morphology (Abu Alhaija, Al Zo'ubi, Al Rousan, & Hammad, 2010; Braun et al, 1995; Proffit, Fields, & Nixon, 1983; Ringqvist, 1973; Sondang et al, 2003; Szymańska & Sidorowicz, in press). The mean bite force was twice as great in the normal as in long face subjects (Proffit et al, 1983).…”

The mean bite force was twice as great in the normal as in long face subjects (Proffit et al, 1983). Sondang et al (2003) reported that a larger bite force implies a greater mandibular plane angle and smaller gonial angle, suggesting that long face subjects exert a lower level of bite force.…”

Development of the masticatory system is influenced by functional needs. Furthermore, masticatory exercise can improve masticatory function. The aim of this study was to evaluate the potential effect of the gum chewing exercise on the maximum bite force (MBF) in adult subjects with different facial morphologies. MBF was measured by a portable occlusal force gauge and lateral cephalogram was used for evaluation of craniofacial morphology in 19 individuals (7 males and 12 females) with a mean age of 25.4 years (SD ± 4.3). The volunteers underwent gum chewing exercise for 5 min twice a day for 4 weeks. MBF was measured before (T1) and after the 4‐week exercise (T2). The facial morphology of the subjects was classified into the brachy (n = 7), mesio (n = 7), and dolicho (n = 5) facial types. In all three groups, exercise was associated with a significant increase in MBF, though the percent increase was highest in the dolicho facial type. We conclude that gum chewing exercise can improve masticatory performance, especially in individuals with dolicho facial morphology.

“…Some previous studies of the elderly have found that occlusal force is associated with age, gender 12) , change in occlusal direction 13) , the presence of implants or dentures 1) , facial morphology 14) , and craniomandibular disorders 11) . Most studies have used either transducers or a T-scan system in evaluating occlusal force.…”

Objectives: The goal of the present study was to investigate the relationship between occlusal function and body composition in 108 premenopausal healthy Japanese women aged 20-45 years.Methods: Pressure-sensitive sheets were used to measure occlusal function. Whole fat mass and lean mass, fat-free mass, and whole-bone mineral content were measured by dual-energy X-ray absorptiometry (DXA).Results: After being adjusted for age and the square of height, the whole lean mass and grip strength of the large occlusal contact-area group were found to be significantly higher than those of the small occlusal area groups (p<0.05, respectively). In the 1-year follow-up study, changes in weight in the small-occlusal contact-area group and the low-occlusal force group were significantly larger than other occlusal-contact area or occlusal-force groups. The mean occlusal-contact area and occlusal force were both significantly smaller in subjects with partial dentures than in those without (p<0.05).Conclusion: Large occlusal contact-area, high occlusal force, and no dentures may be associated with some good health conditions in premenopausal Japanese women.
