Palatal expansion is frequently applied in correction of maxillary transverse deficiency and upper dental arch constriction. 腭扩展是正畸常用的矫治上颌横向发育不足及上颌牙弓狭窄的固定矫治技术。
A Comparative Study of Fixed Palatal Arch and Face Bow in Reinforcing the Maxillary First Molar Anchorage 固定式横腭杆口外弓加强上颌磨牙支抗的比较研究
Objective To acquire the influence of different kinds of palatal lateral excisions on maxillary and dental arch growth and development by measuring the maxilla and dental arch width of models with different kinds of palatal lateral excisions continuously. 目的通过建立腭裂手术不同松弛切口动物模型,连续性测量上颌骨和牙弓宽度变化,了解不同松弛切口愈合对上颌骨及牙弓生长发育的影响作用。
The experiment also show the removable heavy labial wire anchorage system is better than Nance palatal arch and lip bumper. 实验研究也显示在阻止磨牙近中移动方面,该系统优于腭托及唇挡。
Conclusion: The palatal implant can significantly reinforce the anchorage of the molar and it is more effective than transpalatal arch. 结论:腭部种植支抗能明显加强磨牙的支抗,这种作用优于横腭杆。
Results: The amount of bleeding was lower than 20 ml. The palatal arch and the uvula were swelled little. Pseudomembrane sprouted 12 to 18 hours later. 结果:术中术后均无大出血,出血量均<20ml,腭弓、悬雍垂肿胀轻,伪膜于12~18h后萌出,术后12h后进半流质饮食。
Objective: To study changes of dental and palatal arch forms between adults and children after rapid maxillary expansion ( RME). 目的:比较观察经上颌快速扩大(RME)矫治后,成人与儿童牙弓和腭弓形态的变化差异。
In the traditional treatment programs, commonly used means of control are extraoral anchorage bow, intermaxillary traction, transverse palatal bar, Nance arch, lips files, tongue arch and so on. 在传统的治疗方案中,常用的支抗控制手段有口外弓、横腭杆、Nance弓、唇挡、舌弓等。
