This study examined the potential for dental magnets to act as a driving force for osteogenesis in the palate of newborns with a unilateral cleft lip and palate. In the first part of the study dental magnets were arranged in a set up mimicking a distraction device and the curves of the magnetic attraction force versus gap distance curves generated, with and without the presence of palatal rugae tissue in between both sides of the distraction device. The attraction forces ranged from 1 to 12 N depending on the gap distance and the presence of soft tissue in the gap. In the second part of the study these forces were used as input for a 3D finite element model of the palate of a newborn affected by unilateral cleft lip and palate. In the analysis of load transfer, it was found that the strains generated by a magnetically induced distraction exceed 1,500 µstrain suggesting that bone locally is submitted to mild overload leading to bone apposition.

这项研究检查了牙科磁铁作为单侧唇裂和腭裂新生儿上颚骨生成驱动力的潜力。在研究的第一部分中，牙科磁铁被布置在一个模拟牵引装置的装置中，并生成了磁吸引力与间隙距离曲线的曲线，在牵引装置两侧是否存在腭皱组织. 吸引力的范围从 1 到 12 N，具体取决于间隙距离和间隙中软组织的存在。在研究的第二部分，这些力被用作受单侧唇裂和腭裂影响的新生儿的腭部 3D 有限元模型的输入。在载荷传递分析中，发现磁致牵引产生的应变超过 1，
