牙槽突裂植骨前后上颌矫形力对牙槽突位移影响的有限元分析
Effect of Maxillary Orthodontic Force on Alveolar Displacement before and after Alveolar Cleft Bone Grafting:A Finite Element Analysis
摘要
Abstract
Objective To simulate and compare the effect of maxillary orthodontic treatment on three-dimensional displacement of alveolar bone before and after alveolar cleft bone grafting.Methods On the finite element model of the original maxilla with cleft lip and palate,alveolar process bone grafting was simulated to form finite element models before and after alveolar process bone grafting.The same maxillary orthodontic force was added to both models,and the displacements of the alveolar process were observed.Results The displacement nephograms of the X-axis,Y-axis,and Z-axis showed an increasing trend of displacement in the maxillary alveolar bone area of both models;In the pre graft model,the displacement in the X-axis direction was significantly greater than that in the Y-axis and Z-axis(P＜0.01),while in the post graft model,the displacement in the Z-axis direction was significantly greater than that in the X-axis and Y-axis(P＜0.01).Conclusion Combination of maxillary horizontal with sagittal orthodontic treatment before and after bone grafting can increase displacement of the alveolar process in the three-dimensional direction.Before bone grafting,the sagittal orthodontic force should be appropriately increased,and after bone grafting,the horizontal orthodontic force should be appropriately increased.关键词
