骨牵张成形术是指机械拉伸已有骨组织以产生新骨的一个过程,其原理已在腭部快速扩弓及面中部牵引中得以应用,均是利用牵张骨缝以产生新骨,从而达到改建的效果。同样,作为牙槽骨与牙之间的“骨缝”的牙周韧带对于牵张的反应也应是相似的。对此,本文作者提出了“牙牵张”(dental distraction)这一新概念,即通过牵张牙周韧带以快速后移尖牙,并对其结果进行了讨论。 Osteoflage surgery refers to the process of mechanical stretching of bone tissue to produce new bone, the principle of which has been rapidly palatal expansion and surface traction in the middle of the plane are used to stretch the suture to produce new bone , So as to achieve the effect of reconstruction. Similarly, the periodontal ligament, which is the “suture” between the alveolar bone and the tooth, should respond similarly to stretch. In response, the authors propose a new concept of “dental distraction”, which is to rapidly re-position the canines by distracting the periodontal ligament, and the results are discussed.
