In order for bite forces to be used clinically, they must be reliable. While bite force transducers are accurate and precise during bench tests, widely varying reliabilities of intra-oral bite forces have been reported when measured in human subjects. Because few studies have reported total reliability, the clinical use of intra-oral bite forces measurements remains questionable. The purposes of this study were to (i) estimate total reliability, including both within- and between-session reliabilities, of repeated maximum incisor and molar bite force measurements and (ii) demonstrate how extraneous variation affects reliability by comparing estimates for which the effects of age have and have not been controlled. A sample of 28 healthy subjects with Class I normal occlusion (seven subjects in each of four age groups: 5, 8, 11 and 14 years) performed two sessions approximately 90 min apart. Each session consisted of three maximum voluntary bites at three bite positions (incisor and right and left molars). For each bite position, between-subject variance (true variance), between-session variance and within-session variance were calculated using Multilevel modelling procedures. The variances were used to estimate between-session reliabilities, within-session reliabilities and total reliabilities. Within-session reliabilities were substantially higher than between-session reliabilities, which in turn was higher than total reliabilities at all bite positions. Reliabilities were highest at the incisor bite position. Not controlling for age effects substantially overestimated total reliability at all bite positions. After controlling for age effects, total reliabilities of repeated maximum bite forces were low to moderate.

“…4). The measurements were performed using an occlusal bite force transducer [29]. Six measures of 5 s duration were performed, acquiring data of occlusal force every 0.02 s. In each session, the maximum bite force in the molar, premolar and incisor regions was recorded.…”

The results from the patient analyzed showed that fixed support prostheses on three implants are not recommended from a structural point of view because they do not adequately support occlusal loads. Excessive stress in the superstructure and the cortical bone can be expected, which would anticipate the failure of the restoration. Fixed support prostheses on four implants with a cantilever length of 10mm properly resist occlusal loading.

“…For example, to measure tendon force, a metal buckle has to be implanted around the tendon (Biewener et al, 1988) and to measure joint contact forces, a force transducer has to fit around a joint (Westerhoff et al, 2009). Most applications require developing custom-made transducers for specific anatomical constraints, degrees of freedom (Dai et al, 2011), ergonomics (Isaza et al, 2009) and sensitivity requirements (Reinhardt et al, 2009). Strain gages bonded to doubly supported or cantilever beams are the basis of most force transducers used to estimate deflecting forces ranging from millinewtons to several newtons (Bartsch et al, 2007;Zumwalt et al, 2006).…”
