In the original Table 1, some of the data under the column labelled ‘Total’ are reported incorrectly but the data used in the analyses are correct. Some rows in the ‘Total’ column incorrectly list the instantaneous force magnitude applied to the mandible at the time being modelled instead of the mean normalized electromyographic (EMG) magnitude at time of maximum strain magnitude in the lower lateral gauge. We have corrected the data in the ‘Total’ column and now report in Table 1 below the mean normalized EMG magnitude at time of maximum strain magnitude in the lower lateral gauge. The authors apologize for any inconvenience caused.
