A preliminary study of maximum voluntary bite force and jaw muscle efficiency in pre-orthognathic surgery patients

Bite Force Evaluation of Mandibular Fractures Treated With Microplates and Miniplates

“…The bite force is related to different factors, such as tactile impulses, pain and pressure reception in the periodontal ligament, the number of residual teeth, and a visible decrease in the bite force with age owing to the age-dependent deterioration of dentition. 12,13 The complication rate of infections observed in this study was comparable to those in previous studies.…”

“…Hence, the fixation requirements based on the maximum voluntary bite force in noninjured subjects may be inflated, and this is may be the reason the semirigid form of fixation, such as monocortical fixation, has been used successfully. 12,13 An experimental study was performed by Feller et al 11 on the load-carrying capacity of a 2-piece acrylic model, which was connected by 2 titanium miniplates or 1 titanium microplate plus 1 titanium miniplate. They found that the loading capacity of the 2 miniplates was 470 N and that of the microplate/miniplate combination was 267 N. They found that the masticatory loads on the plates exceeding 200 N occurred 3 months after osteosynthesis.…”

Measurement of the Maximum Bite Force in the Natural Dentition with a Gnathodynamometer

“…The higher value in the molar region is explained by the greater periodontal area of the distal teeth in the natural dentition (6). The state of the dentition also has an influence on the maximum bite force -the type of the prosthetic construction, the number of natural teeth and the state of their periodontium (7). It is considered that generally the values of the maximum bite force in men are greater than in women and tend to decrease with age (8).…”

Effect of treatment of dentofacial deformities on the electromyographic activity of masticatory muscles

“…Adult individuals with dentofacial deformities opt for orthosurgical treatment for aesthetic and functional reasons 21 , with mastication being one of the main complaints. Several investigators have reported that individuals with dentofacial deformities, when compared to individuals with normal dental occlusion, have lower EMG activity in the masticatory muscles 3,12,14,15,22,23 , lower occlusal force 2,5,6,10,[13][14][15]19,22,23,25 , few occlusal contacts 6,10 , and lower masticatory efficiency 8,9,22 . The reasons for these lower values of muscle function have not been fully elucidated, but some investigators have attributed them to the different sensory experiences of individuals with dentofacial deformities or to a lower motivation of these individuals to generate force 14,15 .…”
