The influence of gender and bruxism on the human maximum bite force

Abstract

The objective of this research was to evaluate the influence of gender and bruxism on the maximum bite force. The concordance for the physical examination of bruxism between examiners was also evaluated. One hundred and eighteen individuals, from both genders, bruxists and non-bruxists, with an average age of 24 years, were selected for this purpose. For group establishment, every individual was submitted to a specific physical examination for bruxism (performed by three different examiners). Subjects were then divided into four groups according to gender and the presence of bruxism. The maximum bite force was measured using a gnathodynamometer at the first molar area, three times on each side, performed twice. The two measurements were made with a 10-day interval. The highest value was recorded. The mean maximum bite force was statistically higher for males (587.2 N) when compared to females (424.9 N) (p<0.05), regardless of the presence of bruxism. The presence of bruxism did not influence the bite force (mean maximum bite force value for bruxists: 490.1 N, and for non bruxists: 522.1 N) (p>0.05). The concordance between examiners for physical examination of bruxism was considered optimal.

Biting Performance and Skull Biomechanics of a Chisel Tooth Digging Rodent (Ctenomys tuconax; Caviomorpha; Octodontoidea)

“… Bite force plotted against body mass in different species of subterranean rodents from tuco‐tucos (genus Ctenomys ), African mole‐rats (genus Fukomys ), and pocket gophers (genus Geomys ), and other mammals (data from Calderón et al, ; Christiansen, ; Freeman and Lemen, ; Van Daele et al, ; Becerra et al, ). Other Rodentia includes: Peromyscus leucopus , Onychomys leucogaster , Reithrodontomys megalotis , Zapus hudsonius , Perognathus flavescens , Dipodomys ordii .…”

“…The data were taken from Van Daele et al (), Freeman and Lemen (; Fig. ), Calderón et al (), Christiansen (), and Becerra et al (). The bite forces compared were measured at similar jaw position (anterior teeth).…”

Assessment of stress distribution around implant fixture with three different crown materials

“…The greatest natural forces exerted against teeth or implants during mastication can range from 42 to 1245 N. The average magnitude of force is greater in the molar region (200 lb), less in the canine area (~100 lb), and least in the anterior incisor region (~25e35 lb) [14]. These average bite-forces increase with parafunction to magnitudes that may approach 1000 lb [15]. It has been suggested that the general features of mastication in patients with normal and implant e restored dentition are approximately the same [16].…”

Gnathodynamometer - A Reliable Device for Assessing Jaw Bite Force

“…(8) In addition, bite force has been considered important in the diagnosis of the disturbances of the stomatognathic system. (9) Measuring bite forces to evaluate treatment modalities became increasingly popular. It is being applied for,  Measuring functional outcome after fracture reduction.…”
