概括
迷你螺旋锁大伸缩 (MAMP) 和骨锁大伸缩 (BAMP) 均有效治疗III类缺陷. BAMP实现了更大的上腔的提升,而MAMP导致了更大的鼻腔尺寸.
科学领域:
- 矯正牙醫和牙臉整形醫學
- 面生物学 面生物学
- 在正牙科中使用生物材料.
背景情况:
- 骨III类缺陷在成长期患者中是一个重大挑战,通常需要骨科干预来纠正大缺陷.
- 大延伸技术旨在推进中脸部,改善面部美学和功能.
- 使用小螺丝或小板的骨固定,与传统的牙固定相比,提供了一种更受控制的方法来进行尾伸展.
研究的目的:
- 为了比较三维 (3D) 治疗结果的迷你螺杆固定大延伸 (MAMP) 和骨固定大延伸 (BAMP) 在成长中的患者骨III类缺陷.
- 为了评估和量化骨和牙的变化诱导每个延伸协议.
- 为了评估两种骨架固定方法之间的部位移和鼻腔尺寸的差异.
主要方法:
- 追溯性研究比较了两个骨定大伸缩协议:MAMP (n=22) 和BAMP (n=24).
- 患有III类骨缺陷的患者被用III类弹性皮带治疗,这些弹性皮带固定在上扩展器和下骨固定装置上 (MAMP的小螺丝,BAMP的小板).
- 通过使用圆束计算机断层扫描 (CBCT) 扫描分析了三维位移,这些扫描叠加在头骨底部. 统计分析包括协差分析 (ANCOVA).
主要成果:
- 两种MAMP和BAMP疗法都导致了骨III类缺陷的显著改善.
- 与BAMP组相比,MAMP组表现出较少的前部和3D部位移 (MD:分别为-1.09 mm和-1.27 mm).
- 与BAMP组相比,在MAMP组 (MD: 2.36 mm) 中观察到鼻腔宽度显著增加. 部变化在两组中都相似且可以忽略不计.
结论:
- MAMP和BAMP都是有效的3D骨固定方法,用于在患有III类恶性闭塞的成长期患者中进行尾延伸.
- 在BAMP治疗中,表达了更高程度的上腺进步.
- 马普疗法对扩大鼻腔的效果更为明显,这表明改善鼻腔呼吸的潜在益处.

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
