Activator矫治器是较早用于临床的功能矫治器,由Andresen于1908年设计,对安氏Ⅱ类1分类错畸形患者有良好的治疗效果,通过前移下颌刺激下颌骨的生长且抑制上颌矢状向生长,从而调节上下颌骨矢状向的关系。目前,关于Activator矫治器的矫治原理还存在较多的分歧,其中之一就有Activator是否能刺激下颌髁突的生长,使下颌升支增长,增加下颌的综合长度。近年来,学者们从临床和动物实验2个方面进行了许多研究。本文就Activator矫治器对颞下颌关节的影响,及其与颞下颌关节紊乱病的关系作一综述。
The Activator appliance, an early functional clinical appliance, was designed by Andresen in 1908 to provide good treatment for patients with Class 1 division 1 malformations, by advancing the mandible to stimulate mandibular growth and inhibiting maxillary Sagittal growth, thereby adjusting the sagittal mandibular relationship. At present, there are still many disagreements about the principles of Activator appliance. One of them is whether Activator can stimulate the growth of the mandibular condyle, increase the mandibular ascending branch, and increase the combined length of the mandible. In recent years, many studies have been conducted on two aspects of clinical and animal experiments. In this paper, the effects of Activator appliance on temporomandibular joint and its relationship with temporomandibular disorder were reviewed.
