7. CONCLUSION
This study describes 3D model of the mechanism of the skull and lower jaw consisting
of two bodies and two joints. Kinematical and force conditions inputting into this model
were obtained experimentally, muscle physiological properties literary.
Those data were used for the creating of equilibrium equations and problem was solved
by static optimization, according to various criteria. Calculated muscle strength and
muscle forces resulting sequences were compared with the applied literature [6,8] with a
very good agreement.
The calculation was done also with simulation of TMJ implantation, which means the
masseter and temporalis muscle was interrupted where TMJ was implanted. Was shown
that every muscles on both bolus and balance sides increase force values and help
stabilizing and closing jaw function. The closing mouth function on the side with
interrupted muscle is adopted by musculus pterygoideus. There is no difference if
interrupted muscles are on bolus or balance side. Obtained results are close to published
conclusions in literature [9].
