摘　　要：目的观察麻花丝舌侧固定保持器、超强纤维舌侧固定保持器和Hawlay’s活动保持器对牙周组织的影响。方法选择36例固定矫治结束的正畸患者,去矫治器,全口洁治,牙面抛光,测量牙龈指数、菌斑指数、牙石指数为基线水平,随机分成3组,分别戴入Hawlay’s活动保持器、麻花丝舌侧固定保持器和超强纤维舌侧固定保持器。测量1周后及1、3、6个月后的牙周指数。结果麻花丝和超强纤维两种舌侧固定保持器的临床牙周指数明显高于Hawlay’s活动保持器,其中麻花丝固定保持器对牙周指数的影响高于超强纤维固定保持器。结论固定保持器对牙周健康的影响大于活动保持器,其中麻花丝舌侧固定保持器的影响更为明显。Objective To evaluate the periodontal effects of two kinds of bonded lingual fixed retainer and removable retainer.

The changes of periodontal clinical symptoms were assessed by GI, PLI, CI after one week, one month, three months, and six months. Results The GI, PLI, CI of group B and group C were significantly greater than those of group A, and these values of group B were greater than those of group C.
