摘　　要：目的:探讨腭裂术后腭部不同部位瘢痕力对上颌骨的作用机制。方法:在建立的腭裂上颌骨三维有限元模型上,利用Ansys软件分组模拟腭部瘢痕力。第一组:整个腭板口腔面施加载荷力;第二组:裂隙缘处施加载荷力;第三组:腭板口腔面的外1/3处施加载荷力;第四组:腭板口腔面的内2/3处施加载荷力。结果:4组上颌骨均发生形变,第三组>第一组>第四组>第二组。结论:4组腭部瘢痕力均对上颌骨发育产生抑制。腭板口腔面近牙槽突区的瘢痕力影响最大,腭板口腔面内侧瘢痕力影响次之,裂隙区瘢痕力影响最小。Objective:To study the impact of palatal scar at different area on the development of maxilla with cleft palate after repair operation.Methods:On the established three-dimensional finite element model of the maxilla with cleft palate,Ansys was used to simulate palatal scar force in 4 groups.The loading force was applied to the whole oral surface of palatine plate(group 1),at cleft edge(group 2),at the 1/3 of the external oral surface of palatine plate(group 3)and 2/3 of he internal oral surface of palatine plate(group 4)respectively.Maxillary deformation after loading was analyzed.Results:Maxillary deformation occurred in all 4 groups:that of group 3>group 1>group 4>group 2.Conclusion:The scar force can inhibit the development of maxilla.The scar near the alveolar region is the most potential,followed by the scar on the medial side of palate and then at the cleft area.
