The surgically assisted rapid maxillary expansion is a clinical surgical procedure which is used for the patients lacking in transverse match between upper and lower jaws and with malocclusions. Depending on the judgment of a clinician doing treatment, different kind of surgical procedures are adapted. In reality the best method chosen among the different procedure varies with the clinician’s personal subjective experiences. The aim of this study was to analyze the displacement (strain) and stress distributions using Finite Element Method (FEM) following the applications of different surgical procedures during surgically assisted rapid maxillary expansion. Methods: There were two groups which were control and test group, subjects to which the FEM analysis was performed in this study. In control group non-surgical rapid maxillary expansion was applied while in test group surgically assisted rapid maxillary expansion was applied. Results: This analysis allowed the choice of location for the surgical operations and determination of the procedures for the surgically assisted rapid maxillary expansion. The maximum strain was substantially increased from Test 1 to Test 4 which was due to the application of pterygomaxillary separation and it is indicated that pterygomaxillary separation is the most effective surgical method for rapid maxillary expansion. Conclusion: This study predicted methodology of clinical treatments of patients with maximum efficiency in the shortest time on the basis of FEA.
