牙槽骨强直（替代性吸收）是撕脱牙再植术后的一种严重并发症。本研究旨在探讨咀嚼刺激对撕脱牙再植后牙槽骨强直的影响。提取猴上切牙，风干1 h，进行牙髓治疗并再植。未使用夹板。在8周的愈合期内，一组猴子被给予硬颗粒食物，而另一组被给予软食物。用形态计量学方法对牙周状况进行组织学评价。给予硬颗粒食物的猴子的再植牙齿与给予软食物的猴子的牙齿相比，具有显著更少的关节强直和更大的由正常牙周膜包围的牙根面积。总之，发展强直似乎是部分防止或减少咀嚼刺激。
Dentoalveolar ankylosis (replacement resorption) is a serious complication after replantation of avulsed teeth. The purpose of the present study was to investigate the influence of masticatory stimulation on dentoalveolar ankylosis after replantation of avulsed teeth. Monkey upper incisors were extracted, air-dried for 1 h, endodontically treated and replanted. No splinting was used. One group of monkeys was given hard pelleted food, while another group was given soft diet during a healing period of 8 wk. The periodontal conditions were evaluated histologically with a morphometrical method. The replanted teeth of the monkeys given the hard pelleted food had significantly less ankylosis and a larger area of the root surrounded by a normal periodontal membrane than the teeth from the monkeys given a soft diet. In conclusion, development of ankylosis seemed to be partially prevented or reduced by masticatory stimulation.
