- 牙面部整形外科 牙面部整形外科
- 生物材料是一种生物材料.
背景情况:
- 在成长中的患者中,II类缺陷很常见.
- 有效的校正策略对于最佳结果至关重要.
- 透明对齐器提供了一个不那么明显的治疗选择.
研究的目的:
- 评估II类校正使用透明调整器对骨和牙的影响.
- 为了比较II类弹性与下前进 (MA) 与清晰对齐器.
主要方法:
- 研究了66名正在成长中的II类患者:45名接受了清晰对齐剂 (20弹性,25MA) 和21名对照患者的治疗.
- 在T1和T2进行了脑表测量和研究造测量.
- 在各组之间评估了骨和牙变化.
主要成果:
- 两个清晰对齐器组都被纠正为I类,与控制组不同.
- MA组显示了显著的骨变化 (SNA,ANB减少) 和dentoalveolar纠正.
- 弹性组显示出牙气囊纠正与显著的下切口倾斜;没有显著的骨变化.
结论:
- 带有弹性或MA的清晰对齐器对正在成长的患者的II类纠正有效.

02:07Improving Translational Accuracy
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...
