Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

科学领域:

  • 矯正牙科 矯正牙科是一種矯正牙科.
  • 面外科手术 面外科手术
  • 生物材料是一种生物材料.

背景情况:

  • 成年人快速 palatal 扩张由于结成熟提出了独特的挑战.
  • 微植入器辅助快速 palatal 扩张 (MARPE) 和骨大扩张器 (BAME) 是大扩张的先进技术.

研究的目的:

  • 为了比较MARPE和BAME在成年人关于皮质骨变化,中侧侧并行性,和骨横向尺寸.
  • 评估这些扩张方法对特定面结构的影响.

主要方法:

  • 18名成年患者接受MARPE治疗,18名接受BAME治疗.
  • 形束计算断层扫描 (CBCT) 扫描在扩张前和后获得.

主要成果:

  • 无论是MARPE还是BAME,都显著增加了上和下的宽度.
  • 在治疗后,深度显著下降.
  • 皮质骨插入和宽度显示非显著的增加.
  • 与MARPE相比,BAME显示前部口的频率更高.
  • 在这两组中,无论成熟程度如何,中间部口都平行.

结论:

  • 马尔佩和BAME在中侧线平行性和皮层骨变化方面产生了可比的结果.
  • 这两种方法都有效地增加了成年巴的横向尺寸.
  • 在MARPE和BAME之间做出选择可能取决于特定的治疗目标,例如前部口.
