This pilot study describes responses of Sprague Dawley rats to mandibular retrusion. Lingually overcontoured crowns were cemented onto maxillary incisors to produce 3.5 mm of autoretrusion. Monitoring data indicate that activity was suppressed and nutritional intake was reduced. Histological evaluation of the 2-, 4-, 7-, and 59-day test specimens detected only a monocytic infiltrate response in the 4-day group.
这项初步研究描述了斯普拉格-道利大鼠对下颌后缩的反应。将舌侧轮廓过度的牙冠粘固在上颌切牙上，以产生3.5毫米的自动后缩。监测数据表明活动受到抑制，营养摄入减少。对2天、4天、7天和59天测试样本的组织学评估仅在4天组中检测到单核细胞浸润反应。
