Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. Various forms of skeletal anchorage, including miniscrews and miniplates, have been reported in the literature. Recently, great emphasis has been placed on the miniscrew type of temporary anchorage device (TAD). These devices are small, are implanted with a relatively simple surgical procedure, and increase the potential for better orthodontic results. Therefore, miniscrews not only free orthodontists from anchorage-demanding cases, but they also enable clinicians to have good control over tooth movement in 3 dimensions. The miniplate type also produces significant improvements in treatment outcomes and has widened the spectrum of orthodontics. The purpose of this paper is to update clinicians on the current concepts and versatile uses and clinical applications of skeletal anchorage in orthodontics.
自从在正畸治疗的支抗手段中引入微型种植体以来,正畸领域的范式已经开始转变。文献中报道了各种形式的骨支抗,包括微螺钉和微型钛板。最近,人们非常重视微螺钉型临时支抗装置(TAD)。这些装置体积小,植入手术相对简单,并且增加了获得更好正畸效果的可能性。因此,微螺钉不仅使正畸医生从对支抗要求较高的病例中解脱出来,还使临床医生能够在三维空间中很好地控制牙齿移动。微型钛板类型在治疗效果上也有显著改善,并拓宽了正畸学的范畴。本文的目的是向临床医生介绍正畸中骨支抗的当前概念、多种用途及临床应用。
