Correlation between maximum bite force and craniofacial morphology of young adults in Indonesia

Abstract

The present study was conducted to evaluate the relationship between maximum bite force and craniofacial morphology. Sixty-four Indonesian female dental students aged 19-27 years with normal occlusion served as the subjects. The Dental Prescale System was used to measure the maximum bite force using a pressure sensitive sheets while craniofacial morphology measurements were determined from conventional lateral radiograms. The antero-posterior and right-left position of the occlusal load centre (the OLC) were measured also. Stepwise multiple regression analysis was performed to evaluate the relationship between bite force and craniofacial morphology while correlation analysis was used to evaluate the antero-posterior position of the OLC related to craniofacial morphology. Fifty-five per cent of the bite force could be explained by variations in the posterior facial height, gonial angle, antero-posterior size of the maxilla, and posterior length of the cranial base. The result showed a larger bite force implies a greater posterior facial height, smaller gonial angle, larger maxilla and straighter posterior length of the cranial base. This study suggests that among Indonesians, maximum bite force could be explained by craniofacial morphology as found in Caucasians. In addition, we proposed a clinical standard of the OLC for the comprehensive evaluation of occlusion.

Effects of gum chewing exercise on maximum bite force according to facial morphology

“…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. Thus, subjects with dolicho facial morphology are likely to have inferior masticatory efficiency (Gomes, Custodio, Jufer, Del Bel, & Garcia, 2010).…”

Occlusal Force in People in Their Sixties Attending College for Elderly

“…A pressure-sensitive film (Dental Prescale; Fuji Photo Film Co., Tokyo) is one such device 10,20) which has been used for occlusal force measurement in a number of studies 5,6,8,11,13,15,16,18) . It is designed to quantify occlusal pressure from occlusal contact marked on a thin horseshoe-shaped strip of film.…”

Application of "Prescale" as an Aid to Clinical Diagnosis in Orthodontics

“…This system is now being used in various fields of dental research, particularly by Japanese researchers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][22][23][24][25][26][27][28][29][30][31][32][33] . These studies have suggested that this system might help evaluating masticatory function and could be applicable to general dental clinical work.…”
