Objective: To test the use of the MT surgical articulator manufactured by Bio art, a company located in São Carlos, SP, Brazil, as an efficient and reliable method for model surgery and to compare the values obtained to those obtained with the Erickson platform.
Material and Methods: Model surgeries were performed using the Erickson platform and the MT surgical articulator and surgical guides were obtained with the following types of jaw movement: advancement of 5.0 mm, posterior intrusion of 5.0 mm, total intrusion of 5.0 mm, left unilateral intrusion of 5.0 mm, left laterality of 5.0 mm, and left rotation of 5.0 mm. The guides were measured using two Erickson platforms, one of them modified with the adaptation of a tip to the caliper. Lin’s coefficient was used to determine the degree of concordance between the two pairs of measurements.
Results: The Lin coefficient obtained in the comparison of the measurements of the guides constructed on the Erickson platform to those obtained with the MT surgical articulator was 0.99721, with the maximum degree of concordance being 1.
Conclusion: There was no statistically significant difference between the measurements of the guides obtained on the Erickson platform and on the MT surgical articulator, a result that validates the use of the MT surgical articulator.
