摘要:

目的 探究在唇腭裂术后瘢痕及上颌扩弓联合前牵引治疗综合影响下上颌骨发育的变化情况。方法 在原腭裂上颌骨有限元模型基础上,利用ANSYS 17.0软件进行布尔操作形成唇腭裂上颌骨有限元模型,同时添加唇腭裂术后瘢痕力及上颌扩弓联合前牵引力进行力学分析。结果 上颌骨在三维方向上均出现明显形变,形变位移比较结果为X轴>Z轴>Y轴。结论 在唇腭裂术后瘢痕及上颌扩弓联合前牵引治疗综合影响下,上颌骨在三维方向上均出现明显生长抑制现象,其中以横向及矢状向生长抑制最明显。

Abstract:

Objective To study the comprehensive impact of scar and maxillary expansion combined with protraction on the development of maxilla with cleft lip and palate after repair operation. Methods In the original finite element model of the maxilla with cleft palate, a finite element model of the maxilla with cleft lip and palate was established by using Boolean operation in ANSYS. Scar force after cleft lip and palate repair and maxillary expansion force combined with protraction were added simultaneously to process the stress analysis. Results Maxillary deformation occurred in the three-dimensional direction. The comparison of displacements was as follows: X-axis>Z-axis>Y-axis. Conclusion Maxillary growth is significantly inhibited in the three-dimensional direction under the comprehensive impact of scar and maxillary expansion combined with protraction after repair operation, especially transverse and sagittal growth.

Key words: cleft lip and palate, scar, orthodontic treatment, maxillary growth, three-dimensional finite element
