Abstract

Objectives

Anchorage is resistance to an unwanted dental movement. The aim of this study is to analyze the biologic background for a correct control of the anchorage and to evaluate the different kinds of anchorage depending on the movement to be obtained.

Materials and methods

A systematic revision of the literature on orthodontic anchorage has been done on US National Library of Medicine on Medline database (www.ncbi.nim.nih.gov/pubmed). Keywords chosen were: “orthodontic and anchorage”. Fifteen articles were chosen: the full texts were evaluated.

Results

A good anchorage depends on the cellular activity of the periodontal system. From a biologic point of view the best anchorage is seen when there are no changes in the periodontal turn over. This can be obtained when the forces acting on the periodontal ligament and on the periodontal bone do not exceed the threshold promoting a dental movement.

Conclusions

The aim of the biomechanical forces is to minimize the unwanted side effects and to maximize the desired dental movements.

正畸锚。文献回顾

目的:支抗是对牙齿不需要的移动的抵抗。本研究的目的是分析正确控制支具的生物学背景，并根据需要获得的运动来评估不同种类的支具。材料与方法对美国国家医学图书馆Medline数据库(www.ncbi.nim.nih.gov/pubmed)上关于正畸支抗的文献进行了系统的修订。选择的关键词为:“正畸与支抗”。选择了15篇文章，对全文进行评价。结果良好的支抗依赖于牙周系统的细胞活性。从生物学的角度来看，最好的固支是在牙周翻转没有变化的情况下。当作用在牙周韧带和牙周骨上的力不超过促进牙齿运动的阈值时，可以获得这一点。结论生物力学力的目的是减少不良的副作用，最大限度地提高牙齿的运动能力。
