Kaukraft

Kaukraft is a term used in dentistry, biomechanics, and comparative anatomy to describe the force generated by the jaw muscles during biting and chewing. It is commonly quantified as the maximum bite force, often abbreviated MVBF, and reported in newtons (N) or sometimes kilograms-force (kgf). The concept encompasses both static biting strength and dynamic chewing performance.

Measurement of kaukraft relies on bite force transducers or pressure-sensitive sensors placed between teeth or on dental appliances. Tests typically include a static maximum voluntary bite, where a person clenches with maximum effort, and dynamic measurements taken during chewing. The bite point (incisors versus molars) and the design of the measuring device influence results because jaw lever mechanics and occlusion alter force transmission.

Values for humans vary widely due to methodology and individual factors. Reported MVBF ranges commonly fall in the hundreds of newtons, with average estimates often cited around 500–900 N, but values can be lower or exceed 1000 N depending on testing conditions, dental status, and anatomy. Factors such as age, sex, dental health, occlusal alignment, muscle strength, and training influence kaukraft.

Applications of kaukraft research include clinical assessment for temporomandibular disorders, orthodontic and prosthetic planning, and evaluation of restorative work and implant performance. In research, bite force data support investigations into feeding ecology, evolution of masticatory systems, and ergonomic design in sports and daily tasks. Cross-study comparisons require careful attention to measurement protocols and calibration to ensure meaningful interpretation.
