Effect of variation in manipulative force on the repetitiveness of centric relation registration: a computer-based...

Measurement of the influence of the degree of applied force on the resulting retruded border position of the mandible established that the position varied significantly in all three dimensions according to variation in the amount of force. On the basis of the analysis of the t-test (sampling error of 8%), it can be concluded that increasing the manipulative force on the mandible in the general male population will result in a significant three-dimensional increase in the distance from centric occlusion to centric relation. The measurement data document the variability of the retruded centric relation position according to the different amounts of applied retrusive force. The data question the choice of the retruded border position on the basis of its clinical repetitiveness.
