To evaluate the maxillary alveolar repositioning of the infants with bilateral cleft lip and palate (BCLP) undergoing computer-aided nasoalveolar molding (CAD-NAM).
A total of 19 BCLP infants undergoing CAD-NAM were recruited as the treatment group, and 21 nonpresurgically treated BCLP patients served as controls. The upper alveolar morphology was measured and evaluated. Changes in all variables between pre- and post-CAD-NAM were compared.
By the end of CAD-NAM, significant difference was found in the P-A, P'-A', and L-ideal midline (P < 0.01); in the sagittal dimensions, significant difference was found in the P-TT', P'-TT', I-TT', A-X, and A'-X' (P < 0.01), while in the vertical dimensions, significant difference was found in the alveolus height in the bilateral canine regions (P < 0.01).
Computer-aided nasoalveolar molding can effectively reduce the cleft gap, correct the alveolar midline deviation, and retract the projection and outward rotation of the premaxilla segment, and normalize the contour of the alveolus.
评估接受计算机辅助鼻牙槽塑形(CAD-NAM)的双侧唇腭裂(BCLP)婴儿的上颌牙槽骨复位情况。
共招募19名接受CAD-NAM治疗的BCLP婴儿作为治疗组,21名未经手术治疗的BCLP患者作为对照组。对上颌牙槽形态进行测量和评估。比较CAD-NAM前后所有变量的变化。
在CAD-NAM结束时,P-A、P'-A'和L-理想中线存在显著差异(P<0.01);在矢状径方面,P-TT'、P'-TT'、I-TT'、A-X和A'-X'存在显著差异(P<0.01),而在垂直径方面,双侧尖牙区牙槽高度存在显著差异(P<0.01)。
计算机辅助鼻牙槽塑形可有效缩小腭裂间隙,纠正牙槽中线偏差,使前颌骨段的突出和向外旋转回缩,并使牙槽轮廓正常化。
