摘　　要：目的研究不同保持方式对牙周健康的影响。方法选择45例固定矫治结束的患者,随机分组,分别使用Hawley保持器、透明压模联冠保持器和固定保持器,于戴入后1周、1个月、3个月和6个月各检查1次,分别记录牙龈指数(GI)、菌斑指数(PI)和牙石指数(CI)。将测量结果作统计学分析。结果通过对使用保持器前后的纵向比较,Hawley保持器组在使用后各项牙周指数增加,但差异无统计学意义。透明压模联冠保持器组GI在使用后有显著性差异。固定保持器组中各项指数都有明显差异,其中CI差异最为明显。结论保持器影响口腔环境,使口腔自洁作用减弱,对牙周组织均有一定的影响,Hawley保持器对牙周组织的影响最小。Objective To evaluate the periodontal implication with three types retainers. Methods Forty five cases were divided into three groups,and three types of retainers were used for each group at random A follow-up periodontal examination was carried out in one week,one month,three months and six months later, respectively.The periodontal condition was scored according to three parameters：GI,PI,CI.Result In the group with Hawley retainer, the parameters GI, PI, CI increased, but showed no statistic difference. The parameter GI of the group with thermoplastic retainer was significant after using the retainer. The group with bonded retainer was more significant in parameters GI, PII, CI, especially the parameter CI. Conclusion Any types of retainers can affect the periodontal health, and the Hawley retainer has little effect on periodontal health.
