支抗种植体的组织学研究进展

Progress of histological study on anchorage implants

支抗种植体是近年来国内外正畸学研究的热点之一。作者通过组织学研究的文献回顾,反映出支抗种植体微螺钉化、自攻化的发展方向。虽然种植支抗的加力时机尚有争论,但微螺钉存在骨结合,可即刻加力、长期应用,牙周损伤可自愈等新观点对传统认识提出了挑战。

The study and the application of anchorage implants had attracted more and more attention from the orthodontists. This article reviewed the histological studies involving the implants used as orthodontic anchorage and found tendency to be micro-implants and self-drilling. The new concepts of osseointegration between micro-implant and bone, immediate loading, long-term loading and periodontal repair after injury from anchorage implant evoked challenges to the conventional understanding.
