| ［摘要］ 目的 对改良式压膜保持器戴用期间的牙周健康状况与Hawley′s保持器戴用期间牙周健康状况进行比较和效果评价。方法 将80例结束固定正畸治疗的患者，随机分为改良式压膜保持器组和Hawley′s保持器组，每组40例，分别于拆除固定矫治装置全口洁牙后（作为基线数据）和戴保持器后1、3、6、12个月进行牙周指数［牙周袋探诊深度(PD)、菌斑指数(PLI)、牙龈指数(GI）］的检测；同时还教会患者自身有效的口腔卫生自我检查与自我维护的方法。结果 (1)无论压膜保持器组或Hawley′s保持器组，除各阶段的PLI与基线数据间差异有统计学意义（P<0.05）外，各阶段的PD、GI差异无统计学意义（P>0.05）；(2)两组间PD在3个月后差异有统计学意义（P<0.05），GI则在12个月后差异有统计学意义（P<0.05）。结论 (1)只要保持器设计制作合理，牙周预防保健措施到位，压膜保持器戴用期间对牙周健康的影响并不明显；(2)无论压膜保持器或Hawley′s保持器，戴用期间都必须采取各种措施预防牙体牙周病变。 |

| ［Abstract］ Objective To protect the periodontal health of patients wearing the reformed transparent full-arch wraparound retainers and evaluate the effects of the oral hygiene care during maintenance. The periodontal conditions were analyzed between the reformed transparent full-arch wraparound retainer and the Hawley′s retainer.Methods Eighty patients required retention after orthodontic treatment were divided into two groups. Patient wore the reformed transparent full-arch wraparound retainers or Hawley′s retainer was random. Each group had 40 patients. All patients were undergone scaling after remove of the fixed appliances and PD, PLI and GI were examined as the basic line data. Afollow-up examinations of PD, PLI and GI of each patient were carried out in one month, three months, six months and twelve months respectively during retention periods. In the mean time, in order to know the periodontal conditions in different periods and treat odontal and periodontal diseases in time, besides general oral health instruction, the methods of oral hygiene examination and maintenance by myself were instructed. Results (1)The data of PLI of basic line were significantly different from other different periods, but PD and GI were not different from other periods in the two groups. (2) PD in three months and GI in twelve months showed significant difference between two groups（P<0.05）.Conclusion (1) There is no bad effects on patient periodontal tissues when they wear transparent full-arch wraparound retainer if only the retainer are well designed and oral hygiene dealt efficiently. (2)No matter what type of retainer patient wear, some methods must be taken to prevent odontal and periodontal diseases. |
