Abstract:
Objective:To study the impact of palatal scar force on the maxilla with unilateral cleft palate by finite element model. Methods:A 3-dimension finite element model of maxilla with cleft palate containing soft tissue was established,the soar force on the maxilla was analyzed by ansys.Results:Cleft area was identified as the center of rotation,cleft side of the maxilla reflected clock-wise rotation and non-cleft side anticlockwise rotation.The maxilla moved from outside to inside in cross section and front to back in the sagittal plane,and the former was greater than the latter.The outside of alveolar process was subjected to stress of mainly drawing force,the inside to stress of mainly compressive force.The deformation of maxilla was mainly in the front-end.Deformation of the alveolar was greater than that of maxilla body.Among deformations of three dimensions,the width was the largest,the length was the smallest,and the height was between both above.Conclusion:Along with the rotation of the maxilla,cleft area becomes gradually smaller.Among the three dimensions,the width is the largest,the length is the smallest and the height is between the both.The af-fect on maxilla is mainly in the front-end.The affect on the alveolar is greater than that on the maxilla body.
