摘要
目的评估一种新设计的微创腭板面罩组合,用于治疗因上颌骨缺损导致的发育性III类错牙合畸形:方法:16 名年龄在 7 到 9 岁之间的混合牙列早期上颌缺损 III 类患者(8 名男孩和 8 名女孩)参与了这项研究,并接受了腭板组合面罩的治疗。口内矫治器和口外矫治器之间连接了口外矫治器;矫治器与咬合面成 30°。每个象限的压力为 250-300 克。在上颌前突之前和之后立即拍摄头颅X光片。此外,还对骨骼测量值进行了测量、制表和统计分析。采用学生 t 检验法比较牵引前和牵引后的测量结果,显著性水平设定为 p 值:SNA角和上颌长度分别增加了3.13±1.52度和2.60±0.75毫米(p),具有统计学意义:腭板面罩组合是上颌骨缺损导致的 III 类错牙合畸形的一种有效替代治疗方法,且疼痛和不适感极小。
Evaluation of Maxillary Protraction Using a Mini Screw-Retained Palatal C-Shaped Plate and Face Mask.
Objective: To evaluate a newly designed minimally invasive palatal-plate face mask combination for the management of developing Class III malocclusion due to maxillary deficiency.
Methods: A sample of 16 Class III patients due to maxillary deficiency in the early mixed dentition (8 boys and 8 girls) aged between 7 and 9 years participated in this study and were treated with a combination of palatal plate face masks. Extra-oral elastics were attached between the intra-oral and extra-oral appliances; the elastics were set at 30° to the occlusal plane. The force magnitude was 250-300 g per quadrant. Cephalometric radiographs were taken before and immediately after maxillary protraction. In addition, skeletal measurements were measured, tabulated, and statistically analyzed. The pre- and post-protraction measurements were compared using the Student's t-test, and the significance level was set at a p-value <0.05.
Results: A statistically significant increase in SNA angle and maxillary length was observed by 3.13±1.52 degrees and 2.60±0.75 mm (p<0.05), respectively, indicating forward maxillary growth. The skeletal and soft tissue patterns were also improved, as evidenced by the statistically significant increase in the ANB angle, Wits appraisal, and H angle by 4.50±1.28 degrees, 5.30±1.86 mm, and 5.02±3.24 degrees (p<0.05), respectively. A favorable clockwise mandibular rotation was observed as evidenced by the increase in the SN/MP angle and the decrease in the SNB angle by 1.46±1.96 degrees and -1.38±1.86 degrees (p<0.05), respectively.
Conclusion: The palatal-plate facemask combination is an effective treatment alternative for Class III malocclusion due to maxillary deficiency with minimal pain and discomfort.
